PRELIMINARY
PDM31096
4 Megabit 3.3V Static RAM
Description
512K x 8-Bit
1
The PDM31096 is a high-performance CMOS static
RAM organized as 524,288 x 8 bits. Writing is
2 ^{accomplished when the write enable (WE) and chip}
enable CE inputs are both LOW. Reading is
accomplished when WE remains HIGH and CE and
OE are both LOW.
3 ^{The PDM31096 operates from a single +3.3V power}
supply and all the inputs and outputs are fully TTL-
compatible.
4 ^{The PDM31096 is available in a 36-pin 400-mil plas-}
tic SOJ package and a 44-pin plastic TSOP (II)
package.
