MCM6229A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 256K X 4 Bit Static Random Access Memory The MCM6229A is a 1,048,576 bit static random access memory organized as 262,144 words of 4 bits, fabricated using high-performance silicon-gate CMOS technology. Static design eliminates the need for external clocks or timing strobes, while CMOS circuitry reduces power consumption and provides for greater reliability. The MCM6229A is equipped with both chip enable (E) and output enable (<3) pins, allowing for greater system flexibility and eliminating bus contention problems. The MCM6229A is available in 400 mil, 28-lead surface-mount SOJ packages. Single 5 V ± 10% Power Supply Fast Access Times:20, 25, 35, and 45 ns Equal Address and Chip Enable Access Times All Inputs and Outputs are TTL Compatible Three-State Outputs Low Power Operation: 170/150/140/130 mA Maximum, Active AC BLOCK DIAGRAM A3 A4 A7 A6 AS ROW DECODER MEMORY MATRIX 512 ROWS x 2048 COLUMNS Al0 ...
