W29C022

´ 8 CMOS FLASH MEMORY

256K

GENERAL DESCRIPTION

The W29C022 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 VPP is

not required. The unique cell architecture of the W29C022 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

- 128 bytes per page

- Active current: 25 mA (typ.)

- Standby current: 20 mA (typ.)

- Page write (erase/program) cycle: 10 mS

(max.)

· Automatic write (erase/program) timing with

internal VPP generation

- Effective byte-write (erase/program) cycle

time: 39 mS

· End of write (erase/program) detection

- Toggle bit

- Optional software-protected data write

· Fast chip-erase operation: 50 mS

· Two 8 KB boot blocks with lockout

· Typical page write (erase/program) cycles: 1K

· Ten-year data retention

- Data polling

· Latched address and data

· All inputs and outputs directly TTL compatible

· JEDEC standard byte-wide pinouts
