W29C040

512K ´ 8 CMOS FLASH MEMORY

GENERAL DESCRIPTION

The W29C040 is a 4-megabit, 5-volt only CMOS page mode EEPROM organized as 512K ´ 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 W29C040 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

- 256 bytes per page

- Active current: 25 mA (typ.)

- Standby current: 20 mA (typ.)

- Page write (erase/program) cycle: 5 mS

(typ.)

· Automatic write (erase/program) timing with

internal VPP generation

- Effective byte-write (erase/program) cycle

time: 19.5 mS

· End of write (erase/program) detection

- Toggle bit

- Optional software-protected data write

· Fast chip-erase operation: 50 mS

· Two 16 KB boot blocks with lockout

- Data polling

· Latched address and data

· All inputs and outputs directly TTL compatible

· JEDEC standard byte-wide pinouts

· Available packages: TSOP and PLCC

· Typical page write (erase/program) cycles:

1K/10K (typ.)

· Read access time: 90/120 nS

· Ten-year data retention

Publication Release Date: May 1999
