W24L01 Datasheet, PDF (1/11 Pages) Winbond – 128K X 8 CMOS STATIC RAM

W24L01
128K × 8 CMOS STATIC RAM
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
