Advance Information  
8M Late Write HSTL  
The MCM63R836A/918A is an 8M–bit synchronous late write fast static RAM  
designed to provide high performance in secondary cache and ATM switch,  
Telecom, and other high speed memory applications. The MCM63R918A  
(organized as 512K words by 18 bits) and the MCM63R836A (organized as  
256K words by 36 bits) are fabricated in Motorola’shighperformancesilicongate  
copper CMOS technology.  
The differential clock (CK) inputs control the timing of read/write operations of  
theRAM. AttherisingedgeofCK, alladdresses, writeenables, andsynchronous  
selects are registered. An internal buffer and special logic enable the memory to  
accept write data on the rising edge of CK, a cycle after address and control  
signals. Read data is also driven on the rising edge of CK.  
FC PACKAGE  
PBGA  
CASE 999D–01  
The RAM uses HSTL inputs and outputs. The adjustable input trip–point (V  
)
ref  
and output voltage (V  
) gives the system designer greater flexibility in  
DDQ  
optimizing system performance.  
The synchronous write and byte enables allow writing to individual bytes or  
the entire word.  
The impedance of the output buffers is programmable, allowing the outputs to  
match the impedance of the circuit traces which reduces signal reflections.
