2.7 Volt
Features

Description
The PDM21048LL is a very low power CMOS static
RAM organized as 131,072 x 8 bits. Writing to this
device is accomplished when the write enable (WE)
and the chip enable (CE1) inputs are both LOW, and
CE2 is high. Reading is accomplished when WE and
CE2 remain HIGH and CE1 and OE are both LOW.
The PDM21048LL operates from a single +2.7V
power supply and all the inputs and outputs are
fully TTL- compatible. The device supports low data
retention voltage for battery back-up operation with
low current.
The PDM21048LL is available in a 32-pin plastic
TSOP (I) and a 32-pin plastic STSOP (I).
High-speed access times
