Motorola, Inc. 1995
256K x 4 Bit Fast Static Random
Access Memory
The MCM6728B is a 1,048,576 bit static random access memory organized
as 262,144 words of 4 bits. This device is fabricated using high performance sili-
con–gate BiCMOS technology. Static design eliminates the need for external
clocks or timing strobes.
This device meets JEDEC standards for functionality and revolutionary pinout,
and is available in a 400 mil plastic small–outline J–leaded package.
Single 5 V
±
10% Power Supply
Fully Static — No Clock or Timing Strobes Necessary
All Inputs and Outputs Are TTL Compatible
Three State Outputs
Fast Access Times: 8, 10, 12 ns
Center Power and I/O Pins for Reduced Noise
