| ADVANCED INFORMATION CY7C1016 256K x 4 Static RAM Features * High speed -- tAA = 10 ns * Output enable (OE) feature * CMOS for optimum speed/power * Center power/ground pinout * Automatic power-down when deselected * TTL-compatible inputs and outputs output enable (OE), and three-state drivers. The device has an automatic power-down feature that significantly reduces power consumption when deselected. Writing to the device is accomplished by taking chip enable (CE) and write enable (WE) inputs LOW. Data on the four I/O pins (I/O0 through I/O3) is then written into the location specified on the address pins (A0 through A17). Reading from the device is accomplished by taking chip enable (CE) LOW while forcing write enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the four I/O pins. The four input/output pins (I/O 0 through I/O3) are placed in a high-impedance state when the device is deselected (CE HIGH), or during a write operation (CE and WE LOW). The CY7C1016 is available in standard 400-mil-wide SOJs. Functional Description The CY7C1016 is a high-performance CMOS static RAM organized as 262,144 words by 4 bits. Easy memory expansion is provided by an active LOW chip enable (CE), an active LOW Logic Block Diagram Pin Configuration SOJ Top View NC A0 A1 A2 A3 CE I/O0 VCC GND I/O1 WE A4 A5 A6 A7 NC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 INPUT BUFFER A1 A2 A3 A4 A5 A6 A7 A8 A9 ROW DECODER SENSE AMPS I/O3 I/O2 I/O1 I/O0 512 x 512 x 4 ARRAY A17 A16 A15 A14 A13 OE I/O3 GND VCC I/O2 A12 A11 A10 A9 A8 NC C1016-2 COLUMN DECODER A0 A 10 A 11 A 12 A 13 A 14 A 15 A 16 A 17 POWER DOWN CE WE C1016-1 Cypress Semiconductor Corporation * 3901 North First Street * San Jose * CA 95134 * 408-943-2600 April 1995 ADVANCED INFORMATION CY7C1016 256K x 4 Static RAM Selection Guide Maximum Access Time (ns) Maximum Operating Current (mA) Maximum Standby Current (mA) Document #: 38-00439 7C1016-10 10 175 55 7C1016-12 12 165 175 50 50 7C1016-15 15 155 165 40 40 Commercial Military Commercial Military Cypress Semiconductor Corporation * 3901 North First Street * San Jose * CA 95134 * 408-943-2600 April 1995 |
