DESCRIPTION

The M5M54R16A is a family of 262144-word by 16-bit static RAMs, fabricated with the high performance CMOS process and designed for high speed application. These devices operate on a single 3.3V supply, and are directly TTL compatible.

They include a power down feature as well. In write and read cycles, the lower and upper bytes are able to be controled either togethe or separately by LB and UB.

FEATURES

? Fast access time M5M54R16AJ,ATP-10 ... 10ns(max)

M5M54R16AJ,ATP-12 ... 12ns(max)

M5M54R16AJ,ATP-15 ... 15ns(max)

? Single +3.3V power supply

? Fully static operation : No clocks, No refresh

? Common data I/O

? Easy memory expansion by S

? Three-state outputs : OR-tie capability

? OE prevents data contention in the I/O bus

? Directly TTL compatible : All inputs and outputs

? Separate control of lower and upper bytes by LB and UB
