Advance Information
512K x 8 Bit Static Random
Access Memory
The MCM6946 is a 4,194,304–bit static random access memory organized as
524,288 words of 8 bits. Static design eliminates the need for external clocks or
timing strobes.
The MCM6946 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 MCM6946 is available in a 400 mil, 36–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: 195/185 / 180 / 175 mA Maximum, Active AC
• Available in TSOP or SOJ Packages
