INTRODUCTION

UT9Q512K32 Quantified Commercial
Off-the-Shelf product is a high-performance 2M byte
(16Mbit) CMOS static RAM multi-chip module (MCM),
organized as four individual 524,288 x 8 bit SRAMs with a
common output enable. Memory expansion is provided by
an active LOW chip enable (En), an active LOW output
enable (G), and three-state drivers. This device has a power-
down feature that reduces power consumption by more than
90% when deselected
.
Writing to each memory is accomplished by taking chip
enable (En) input LOW and write enable (Wn) inputs LOW.
Data on the eight I/O pins (DQ
0
through DQ
7
) is then written
into the location specified on the address pins (A
0
through
A
18
). Reading from the device is accomplished by taking
chip enable (En) and output enable (G) LOW while forcing
write enable (Wn) HIGH. Under these conditions, the
contents of the memory location specified by the address
pins will appear on the I/O pins.
The input/output pins are placed in a high impedance state
when the device is deselected (En HIGH), the outputs are
disabled (G HIGH), or during a write operation (En LOW
and Wn LOW). Perform 8, 16, 24 or 32 bit accesses by
making Wn along with En a common input to any
combination of the discrete memory die.
