Preliminary W27E02

´ 8 ELECTRICALLY ERASABLE EPROM

256K

1. GENERAL DESCRIPTION

The W27E02 is a high speed, low power consumption Electrically Erasable and Programmable Read

Only Memory organized as 262,144 ´ 8 bits. It requires only one supply in the range of 5.0V ± 10% in

normal read mode. The W27E02 provides an electrical chip erase function.

2. FEATURES

· Fully static operation

· Single power supply voltage: 5.0V ±10%

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

· Read operating current: 30 mA (max.)

· All inputs and outputs directly TTL/CMOS

compatible

· Three-state outputs

· Erase/Programming operating current:

30 mA (max.)

· Available packages: 32-pin 600 mil DIP, 32-lead

PLCC and 32-lead STSOP

· Standby current: 20 mA (max.)

· +12V erase/programming voltage
