GENERAL DESCRIPTION

The W29C020C is a 2-megabit, 5-volt only CMOS flash memory organized as 256K

device can be written (erased and programmed) in-system with a standard 5V power supply. A 12-volt

operations with extremely low current consumption compared to other comparable 5-volt flash memory

products. The device can also be written (erased and programmed) by using standard EPROM

programmers.

FEATURES

Single 5-volt write (erase and program)

operations

Fast page-write operations

Fast chip-erase operation: 50 mS

Two 8 KB boot blocks with lockout

Whole chip cycling: 10K (typ.)

Read access time: 70/90/120 nS

Twenty-year data retention

128 bytes per page

Page write (erase/program) cycle: 10 mS

(max.)

Effective byte-write (erase/program) cycle

time: 39 S

Optional software-protected data write

is not required. The unique cell architecture of the W29C020C results in fast write (erase/program)

256K
