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

PowerPC , 486, i960 , and Pentium microprocessors. It is organized as 32K

words of 36 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

control with the use of an external clock (K). BiCMOS circuitry reduces the overall

power consumption of the integrated functions for greater reliability.

positive–edge–triggered noninverting registers.

addresses can be generated internally by the MCM69F536C (burst sequence

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

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

and provides increased timing flexibility for incoming signals.

bytes or to all bytes. The four bytes are designated as “a”, “b”, “c”, and “d”. SBa

controls DQa, SBb controls DQb, and so on. Individual bytes are written if the

selected byte writes SBx are asserted with SW. All bytes are written if either SGW

is asserted or if all SBx and SW are asserted.

Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst

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