GENERAL DESCRIPTION

The MT5C1008 SRAM is a high-performance CMOS

static RAM organized as 131, 072 words by 8 bits, offering low

active power and ultra low standby and data retention current

levels. Easy memory expansion is provided by an active LOW

Chip Enable (CE1\), an active HIGH Chip Enable (CE2), and

active Low Output Enable (OE\), and three-state drivers.

Writing to the device is accomplished by taking Chip Enable

One (CE1\) and Write Enable (WE\) inputs LOW and Chip

Enable Two (CE2) input HIGH. Data on the eight I/O pins (I/O0

through I/O7) is then written into the location specified on the

address pins (A0 through A16).

Reading from the device is accomplished by taking

Chip Enable One (CE

1

\) and Output Enable (OE\) LOW while

forcing Write Enable (WE\) and Chip Enable Two (CE

2

) HIGH.

Under these conditions, the contents of the memory location

specified by the address pins will appear on the I/O pins.

The eight input/output (I/O0 through I/O7) are placed

in a high-impedance state when the device is deselected (CE1\)

HIGH or CE2 LOW), the outputs are disabled (OE\ HIGH), or

during a write operation (CE1\ LOW, CE2 HIGH, and WE\ LOW).
