UT621024
Rev. 1.5
128K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
FEATURES
The UT621024 is a 1,048,576-bit low power
„ Access time : 35/55/70ns (max.)
„ Low power consumption :
Operating : 60/50/40 mA (typical)
Standby : 2µA (typical) L-version
CMOS static random access memory
organized as 131,072 words by 8 bits. It is
fabricated using high performance, high
reliability CMOS technology.
1µA (typical) LL-version
„ Single 5V power supply
„ All inputs and outputs TTL compatible
„ Fully static operation
„ Three state outputs
The UT621024 is designed for low power
application. It is particularly well suited for
battery back-up nonvolatile memory
application.
„ Data retention voltage : 2V (min.)
„ Package : 32-pin 600 mil PDIP
32-pin 450 mil SOP
32-pin 8mmx20mm TSOP-1
The UT621024 operates from a single 5V
power supply and all inputs and outputs are
fully TTL compatible.

Notes :
1. WE or CE1 must be HIGH or CE2 must be LOW during all address transitions.
2. A write occurs during the overlap of a low CE1 , a high CE2 and a low WE .
3. During a WE controlled with write cycle with OE LOW, tWP must be greater than tWHZ+tDW to allow the I/O drivers
to turn off and data to be placed on the bus.
4. During this period, I/O pins are in the output state, and input singals must not be applied.
5. If the CE1 LOW transition occurs simultaneously with or after WE LOW transition, the outputs remain in a high
impedance state.
6. tOW and tWHZ are specified with CL=5pF. Transition is measured ± 500mV from steady state.
