SEMICONDUCTOR TECHNICAL DATA

MCM69P818

256K x 18 Bit Pipelined

BurstRAM Synchronous

Fast Static RAM

The MCM69P818 is a 4M bit synchronous fast static RAM designed to provide

a burstable, high performance, secondary cache for the PowerPC and other

high performance microprocessors. It is organized as 256K words of 18 bits

each. This device integrates input registers, an output register, a 2–bit address

counter, andahighspeedSRAMontoasinglemonolithiccircuitforreducedparts

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

control with the use of an external clock (K).

PBGA

CASE 999–02

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 MCM69P818 (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 synchro-

nous write enable (SW) are provided to allow writes to either individual bytes or

to all 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. 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–triggeredoutput register and then released to the output buffers at the next

rising edge of clock (K).

The MCM69P818 operates from a 3.3 V core power supply and all outputs

operate on a 2.5 V or 3.3 V power supply. All inputs and outputs are JEDEC stan-

dard JESD8–5 compatible.
