CB = total capacitance of one bus line in pF. As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions. The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation. This parameter is not tested but ensured by characterization. For endurance estimates in a specific application, please consult the Total EnduranceTM Model which can be obtained at www.microchip.com.

DS21178G-page 3 24AA00/24LC00/24C00 2.0 2.1 PIN DESCRIPTIONS SDA Serial Data 4.0 BUS CHARACTERISTICS The following bus protocol has been defined: * Data transfer may be initiated only when the bus is not busy. * During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition. Accordingly, the following bus conditions have been defined (Figure 4-1). This is a bidirectional pin used to transfer addresses and data into and data out of the device. It is an open drain terminal, therefore the SDA bus requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz). For normal data transfer SDA is allowed to change only during SCL low. Changes during SCL high are reserved for indicating the Start and Stop conditions. 2.2 SCL Serial Clock 4.1 Bus Not Busy (A) This input is used to synchronize the data transfer from and to the device. Both data and clock lines remain high. 4.2 Start Data Transfer (B) 2.3 Noise Protection The SCL and SDA inputs have Schmitt Trigger and filter circuits which suppress noise spikes to assure proper device operation even on a noisy bus. A high-to-low transition of the SDA line while the clock (SCL) is high determines a Start condition. All commands must be preceded by a Start condition. 4.3 Stop Data Transfer (C) 3.0 FUNCTIONAL DESCRIPTION The 24XX00 supports a bidirectional 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as a transmitter, and a device receiving data as a receiver. The bus has to be controlled by a master device which generates the Serial Clock (SCL), controls the bus access, and generates the Start and Stop conditions, while the 24XX00 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated. A low-to-high transition of the SDA line while the clock (SCL) is high determines a Stop condition. All operations must be ended with a Stop condition. 4.4 Data Valid (D) The state of the data line represents valid data when, after a Start condition, the data line is stable for the duration of the high period of the clock signal. The data on the line must be changed during the low period of the clock signal. There is one bit of data per clock pulse. Each data transfer is initiated with a Start condition and terminated with a Stop condition. The number of the data bytes transferred between the Start and Stop conditions is determined by the master device and is theoretically unlimited. DS21178G-page 4 (c) 2007 Microchip Technology Inc. 24AA00/24LC00/24C00 4.5 Acknowledge Each receiving device, when addressed, is obliged to generate an acknowledge after the reception of each byte. The master device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: The 24XX00 does not generate any Acknowledge bits if an internal programming cycle is in progress. The device that acknowledges has to pull down the SDA line during the Acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge related clock pulse. Of course, setup and hold times must be taken into account. A master must signal an end of data to the slave by not generating an Acknowledge bit on the last byte that has been clocked out of the slave. In this case, the slave must leave the data line high to enable the master to generate the Stop condition (Figure 4-2). FIGURE 4-1: SCL (A) (B) DATA TRANSFER SEQUENCE ON THE SERIAL BUS (C) (D) (C) (A) SDA Start Condition Address or Acknowledge Valid Data Allowed to Change Stop Condition FIGURE 4-2: ACKNOWLEDGE TIMING Acknowledge Bit SCL 1 2 3 4 5 6 7 8 9 1 2 3 SDA Data from transmitter Data from transmitter Receiver must release the SDA line at this point so the Transmitter can continue sending data. Transmitter must release the SDA line at this point allowing the Receiver to pull the SDA line low to acknowledge the previous eight bits of data. (c) 2007 Microchip Technology Inc. DS21178G-page 5 24AA00/24LC00/24C00 5.0 DEVICE ADDRESSING 6.0 6.1 WRITE OPERATIONS Byte Write After generating a Start condition, the bus master transmits a control byte consisting of a slave address and a Read/Write bit that indicates what type of operation is to be performed. The slave address for the 24XX00 consists of a 4-bit device code `1010' followed by three "don't care" bits. The last bit of the control byte determines the operation to be performed. When set to a one a read operation is selected, and when set to a zero a write operation is selected (Figure 5-1). The 24XX00 monitors the bus for its corresponding slave address all the time. It generates an Acknowledge bit if the slave address was true and it is not in a programming mode. FIGURE 5-1: CONTROL BYTE FORMAT Read/Write Bit Device Select Bits S 1 0 1 0 Don't Care Bits x x x R/W ACK Slave Address Start Bit Acknowledge Bit Following the Start signal from the master, the device code (4 bits), the "don't care" bits (3 bits), and the R/W bit (which is a logic low) are placed onto the bus by the master transmitter. This indicates to the addressed slave receiver that a byte with a word address will follow after it has generated an Acknowledge bit during the ninth clock cycle. Therefore, the next byte transmitted by the master is the word address and will be written into the Address Pointer of the 24XX00. Only the lower four address bits are used by the device, and the upper four bits are "don't cares." The 24XX00 will acknowledge the address byte and the master device will then transmit the data word to be written into the addressed memory location. The 24XX00 acknowledges again and the master generates a Stop condition. This initiates the internal write cycle, and during this time the 24XX00 will not generate Acknowledge signals (Figure 7-2). After a byte Write command, the internal address counter will not be incremented and will point to the same address location that was just written. If a Stop bit is transmitted to the device at any point in the Write command sequence before the entire sequence is complete, then the command will abort and no data will be written. If more than 8 data bits are transmitted before the Stop bit is sent, then the device will clear the previously loaded byte and begin loading the data buffer again. If more than one data byte is transmitted to the device and a Stop bit is sent before a full eight data bits have been transmitted, then the Write command will abort and no data will be written. The 24XX00 employs a VCC threshold detector circuit which disables the internal erase/write logic if the VCC is below 1.5V (24AA00 and 24LC00) or 3.8V (24C00) at nominal conditions. DS21178G-page 6 (c) 2007 Microchip Technology Inc. 24AA00/24LC00/24C00 7.0 ACKNOWLEDGE POLLING FIGURE 7-1: Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally timed write cycle. ACK polling can be initiated immediately. This involves the master sending a Start condition followed by the control byte for a Write command (R/W = 0). If the device is still busy with the write cycle, then no ACK will be returned. If no ACK is returned, then the Start bit and control byte must be re-sent. If the cycle is complete, then the device will return the ACK and the master can then proceed with the next Read or Write command. See Figure 7-1 for flow diagram.

DS21178G-page 7 24AA00/24LC00/24C00 8.0 READ OPERATIONS Read operations are initiated in the same way as write operations with the exception that the R/W bit of the slave address is set to one. There are three basic types of read operations: current address read, random read and sequential read. After the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the internal Address Pointer is set. Then the master issues the control byte again, but with the R/W bit set to a one. The 24XX00 will then issue an acknowledge and transmits the eight bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the device discontinues transmission (Figure 8-2). After this command, the internal address counter will point to the address location following the one that was just read. 8.1 Current Address Read The 24XX00 contains an address counter that maintains the address of the last word accessed, internally incremented by one. Therefore, if the previous read access was to address n, the next current address read operation would access data from address n + 1. Upon receipt of the slave address with the R/W bit set to one, the device issues an acknowledge and transmits the eight-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the device discontinues transmission (Figure 8-1). 8.3 Sequential Read Sequential reads are initiated in the same way as a random read except that after the device transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the device to transmit the next sequentially addressed 8-bit word (Figure 8-3). To provide sequential reads the 24XX00 contains an internal Address Pointer which is incremented by one at the completion of each read operation. This Address Pointer allows the entire memory contents to be serially read during one operation. 8.2 Random Read Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, first the word address must be set. This is done by sending the word address to the device as part of a write operation.

Note the following details of the code protection feature on Microchip devices: * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." * * * Code protection is constantly evolving.
