W24L01
128K
8 CMOS STATIC RAM
Publication Release Date: January 2, 2002
- 1 - Revision A6
GENERAL DESCRIPTION
The W24L01 is a normal-speed, very low-power CMOS static RAM organized as 131072
8 bits that
operates on a wide voltage range from 2.7V to 3.6V power supply. The W24L01 family, W24L01-LE
and W24L01-LI, can meet the requirement of various operating temperature. This device is
manufactured using Winbond's high performance CMOS technology.
FEATURES
Low power consumption
Access time: 55 nS /70 nS
2.7V to 3.6V supply voltage
Fully static operation
All inputs and outputs directly TTL compatible
Three-state outputs
Battery back-up operation capability
Data retention voltage: 1.5V (min.)
Packaged in 32-pin 450 mil SOP, standard type
one TSOP (8 mm
20 mm), small type one
TSOP (8 mm
13.4 mm) and 48-pin CSP

Notes:
1. During this period, I/O pins are in the output state, so input signals of opposite phase to the outputs should not be applied.
2. The data output from D
OUT
are the same as the data written to D
IN
during the write cycle.
3. D
OUT
provides the read data for the next address.
4. Transition is measured
500 mV from steady state with C
L
= 5 pF. This parameter is guaranteed but not 100% tested.
