256KB and 512KB BurstRAMTM Secondary Cache Module for PentiumTM
The MCM72BA32SG and MCM72BA64SG are designed to provide a burstable, high performance, 256K/512K L2 cache for the Pentium microprocessor. The modules are configured as 32K x 72 and 64K x 72 bits in a 136 pin dual readout single inline memory module (DIMM). The module uses four of Motorola's MCM67B518 or MCM67B618 BiCMOS BurstRAMs. Bursts can be initiated with either address status processor (ADSP) or address status controller (ADSC). Subsequent burst addresses are generated internal to the BurstRAM by the burst advance (ADV) input pin. Write cycles are internally self timed and are initiated by the rising edge of the clock (K) input. Eight write enables are provided for byte write control. The cache family is designed to interface with popular Pentium cache controllers with on board TAG. PD0 - PD2 are reserved for density and speed identification. * Pentium-style Burst Counter on Board * Dual Readout SIMM for Circuit Density * Single 5 V 5% Power Supply * All Inputs and Outputs are TTL Compatible * Three State Outputs * Byte Parity * Byte Write Capability * Fast Module Clock Rates: 66 MHz, 60 MHz, 50MHz * Decoupling Capacitors for each Fast Static RAM * High Quality Multi-Layer FR4 PWB With Separate Power and Ground Planes * I/Os are 3.3 V Compatible

NOTE: All registers are positive-edge triggered. The ADSC or ADSP signals control the duration of the burst and the start of the
next burst. When ADSP is sampled low, any ongoing burst is interrupted and a read (independent of W and ADSC) is performed using the new external address. Alternatively, an ADSP-initiated two cycle WRITE can be performed by asserting ADSP and a valid address on the first cycle, then negating both ADSP and ADSC and asserting LW and/or UW with valid data on the second cycle (see Single Write Cycle in WRITE CYCLES timing diagram). When ADSC is sampled low (and ADSP is sampled high), any ongoing burst is interrupted and a read or write (dependent on W) is performed using the new external address. Chip enable (E) is sampled only when a new base address is loaded. After the first cycle of the burst, ADV controls subsequent burst cycles. When ADV is sampled low, the internal address is advanced prior to the operation. When ADV is sampled high, the internal address is not advanced, thus inserting a wait state into the burst sequence accesses. Upon completion of a burst, the address will wrap around to its initial state. See BURST SEQUENCE TABLE. Write refers to either or both byte write enables (LW, UW).

NOTES: 1. A read cycle is defined by UW and LW high or ADSP low for the setup and hold times. A write cycle is defined by LW or UW low and ADSP high for the setup and hold times. 2. All read and write cycle timings are referenced from K or G. 3. G is a don't care when UW or LW is sampled low. 4. Maximum access times are guaranteed for all possible Pentium external bus cycles. 5. Transition is measured 500 mV from steady-state voltage with load of Figure 1B. This parameter is sampled rather than 100% tested. At any given voltage and temperature, tKHQZ max is less than tKHQZ1 min for a given device and from device to device. 6. This is a synchronous device. All addresses must meet the specified setup and hold times for ALL rising edges of K whenever ADSP or ADSC is low, and the chip is selected. All other synchronous inputs must meet the specified setup and hold times for ALL rising edges of K when the chip is enabled.Chip enable must be valid at each rising edge of clock for the device (when ADSP or ADSC is low) to remain enabled.
