W29C020C

256K ´ 8 CMOS FLASH MEMORY

GENERAL DESCRIPTION

The W29C020C is a 2-megabit, 5-volt only CMOS flash memory organized as 256K 8 bits. The

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

is not required. The unique cell architecture of the W29C020C results in fast write

(erase/program) 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

Software and hardware data protection

Low power consumption

· Fast page-write operations

- Active current: 25 mA (typ.)

128 bytes per page

Standby current: 20 A (typ.)

Page write (erase/program) cycle: 10 mS

(max.)

· Automatic write (erase/program) timing with

internal V generation

Effective byte-write (erase/program) cycle

· End of write (erase/program) detection

time: 39 S

Toggle bit

Optional software-protected data write

Data polling

· 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

· Latched address and data

· All inputs and outputs directly TTL compatible

· JEDEC standard byte-wide pinouts

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

TSOP, and 32-pin PLCC
