MCM69F618C

64K x 18 Bit Flow–Through

BurstRAM Synchronous

Fast Static RAM

The MCM69F618C is a 1M–bit synchronous fast static RAM designed to pro-

vide a burstable, high performance, secondary cache for the 68K Family,

PowerPC , 486, i960 , and Pentium microprocessors. It is organized as 64K

words of 18 bits each. This device integrates input registers, a 2–bit address

counter, and high speed SRAM onto a single monolithic circuit for reduced parts

count in cache data RAM applications. Synchronous design allows precise cycle

controlwiththeuseofanexternalclock(K). BiCMOScircuitryreducestheoverall

power consumption of the integrated functions for greater reliability.

Addresses (SA), data inputs (DQx), and all control signals except output

enable (G) and Linear Burst Order (LBO) are clock (K) controlled through

positive–edge–triggered noninverting registers.

BurstscanbeinitiatedwitheitherADSPorADSCinputpins. Subsequentburst

addresses can be generated internally by the MCM69F618C (burst sequence

operates in linear or interleaved mode dependent upon the state of LBO) and

controlled by the burst address advance (ADV) input pin.

Write cycles are internally self–timed and initiated by the rising edge of the

clock (K) input. This feature eliminates complex off–chip write pulse generation

and provides increased timing flexibility for incoming signals.

Synchronous byte write (SBx), synchronous global write (SGW), and syn-

chronous write enable SW are provided to allow writes to either individual bytes

or to both bytes. The two bytes are designated as “a” and “b”. SBa controls DQa

and SBb controls DQb. Individual bytes are written if the selected byte writes SBx

are asserted with SW. BothbytesarewrittenifeitherSGW is asserted or if all SBx

and SW are asserted.

For read cycles, a flow–through SRAM allows output data to simply flow freely

from the memory array.

The MCM69F618C operates from a 3.3 V power supply and all inputs and

outputs are LVTTL compatible and 5 V tolerant.
