64K x 18 Bit BurstRAM
Synchronous Fast Static RAM
With Burst Counter and Registered Outputs

The MCM67J618B is a 1,179,648 bit synchronous static random access
memory designed to provide a burstable, high–performance, secondary cache
for the i486 and Pentium microprocessors. It is organized as 65,536 words
of 18 bits, fabricated with Motorola’s high–performance silicon–gate BiCMOS
technology. The device integrates input registers, a 2–bit counter, high speed
SRAM, and high drive registered output drivers onto a single monolithic circuit
for reduced parts count implementation of cache data RAM applications. Syn-
chronous design allows precise cycle control with the use of an external clock (K).
BiCMOS circuitry reduces the overall power consumption of the integrated func-
tions for greater reliability.
Addresses (A0 – A15), data inputs (D0 – D17), and all control signals except
output enable (G) are clock (K) controlled through positive–edge–triggered non-
inverting registers.
This device contains output registers for pipeline operations. At the rising edge
of K, the RAM provides the output data from the previous cycle.
Output enable (G) is asynchronous for maximum system design flexibility.
Burst can be initiated with either address status processor (ADSP) or address
status cache controller (ADSC) input pins. Subsequent burst addresses can be
generated internally by the MCM67J618B (burst sequence imitates that of the
i486) and controlled by the burst address advance (ADV) input pin. The following
pages provide more detailed information on burst controls.
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 flexibility for incoming signals.
Dual write enables (LW and UW) are provided to allow individually writeable
bytes. LW controls DQ0 – DQ8 (the lower bits), while UW controls DQ9 – DQ17
(the upper bits).
This device is ideally suited for systems that require wide data bus widths and
cache memory. See Figure 2 for applications information. Single 5 V ± 5% Power Supply Fast Access Time/Fast Cycle Time = 5 ns/100 MHz, 7 ns/80 MHz Byte Writeable via Dual Write Enables Internal Input Registers (Address, Data, Control) Output Registers for Pipelined Applications Internally Self–Timed Write Cycle ADSP, ADSC, and ADV Burst Control Pins Asynchronous Output Enable Controlled Three–State Outputs Common Data Inputs and Data Outputs 3.3 V I/O Compatible High Board Density 52–Lead PLCC Package ADSP Disabled with Chip Enable (E) — Supports Address Pipelining
