Motorola, Inc. 1995
64K x 4 Bit Static RAM
The MCM6709R is a 262,144 bit static random access memory organized as
65,536 words of 4 bits, fabricated using high–performance silicon–gate BiCMOS
technology. Static design eliminates the need for external clocks or timing
strobes.
Output enable (G) is a special control feature that provides increased system
flexibility and eliminates bus contention problems.
The MCM6709R meets JEDEC standards and is available in a revolutionary
pinout 300 mil, 28 lead plastic surface–mount SOJ package.
Single 5 V
±
10% Power Supply
Fully Static — No Clock or Timing Strobes Necessary
All Inputs and Outputs are TTL Compatible
Center Power and I/O Pins for Reduced Noise
Three State Outputs
Fast Access Times: MCM6709R–6 = 6 ns
MCM6709R–7 = 7 ns
MCM6709R–8 = 8 ns
