W27L02

256K × 8 ELECTRICALLY ERASABLE EPROM

1. GENERAL DESCRIPTION

The W27L02 is a high speed, low power consumption Electrically Erasable and Programmable Read

Only Memory organized as 262,144 x 8 bits. It requires only one supply in the range of 3.3V ±10% in

normal read mode. The W27L02 provides an electrical chip erase function.

2. FEATURES

• +12V erase/programming voltage

• Fully static operation

• Wide range for power supply voltage:

3.3V ±10%

• High speed access time: 70/90 nS (max.)

• Read operating current: 15 mA (max.)

• All inputs and outputs directly TTL/CMOS

compatible

• Three-state outputs

• Erase/Programming operating current:

30 mA (max.)

• Available packages: 32-lead PLCC and 32-lead

STSOP

• Standby current: 20 µA (max.)
