32K x 36 Bit Pipelined BurstRAM
Synchronous Fast Static RAM
The MCM69P536C 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 32K
words of 36 bits each. This device integrates input registers, an output register,
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 cir-
cuitry reduces the overall 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.
Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst
addresses can be generated internally by the MCM69P536C (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 are 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
synchronous write enable SW are provided to allow writes to either individual
bytes or to all bytes. The four bytes are designated as “a”, “b”, “c”, and “d”. SBa
controls DQa, SBb controls DQb, etc. 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.
For read cycles, pipelined SRAMs output data is temporarily stored by an
edge–triggered output register and then released to the output buffers at the next
rising edge of clock (K).
The MCM69P536C operates from a 3.3 V power supply and all inputs and
outputs are LVTTL compatible.
MCM69P536C–4 = 4 ns Access / 7.5 ns Cycle
MCM69P536C–4.5 = 4.5 ns Access / 8 ns Cycle
MCM69P536C–5 = 5 ns Access / 10 ns Cycle
MCM69P536C–6 = 6 ns Access / 12 ns Cycle
MCM69P536C–7 = 7 ns Access / 13.3 ns Cycle
