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 DOUT are the same as the data written to DIN during the write cycle.
3. DOUT provides the read data for the next address.
4. Transition is measured ±500 mV from steady state with CL = 5 pF. This parameter is guaranteed but not 100% tested.
