MOTOROLA FAST SRAM
Motorola, Inc. 1999
1M x 4 Bit Static Random
Access Memory
The MCM6949 is a 4,194,304–bit static random access memory organized as
1,048,576 words of 4 bits. Static design eliminates the need for external clocks
or timing strobes.
The MCM6949 is equipped with chip enable (E) and output enable (G) pins,
allowing for greater system flexibility and eliminating bus contention problems.
Either input, when high, will force the outputs into high impedance.
The MCM6949 is available in a 400 mil, 32–lead surface–mount SOJ package.
Single 3.3 V – 5%, + 10% Power Supply
Fast Access Time: 8/10/12/15 ns
Equal Address and Chip Enable Access Time
All Inputs and Outputs are TTL Compatible
Three–State Outputs
Power Operation: 195/165/160/155 mA Maximum, Active AC
