W29D040C

512K x 8 CMOS FLASH MEMORY

GENERAL DESCRIPTION

The W29D040C is an 4Mbit, 5-volt only CMOS flash memory organized as 512K ´ 8 bits. For flexible

erase capability, the 4 Mbits of data are divided into 8 uniform sectors of 64 Kbytes. The byte-wide (´ 8)

data appears on DQ7- DQ0. The device can be programmed and erased in-system with a standard 5V

power supply. A 12-volt VPP is not required. The unique cell architecture of the W29D040C results in fast

program/erase operations with extremely low current consumption (compared to other comparable 5-volt

flash memory products). The device can also be programmed and erased by using standard EPROM

programmers.

FEATURES

operations

· Typical program/erase cycles:

- 10K/100K

· Fast byte-write operation

· Twenty-year data retention

- Chip programming cycle: 20 S (typ.)

- Chip erase cycle: 1 S (typ.)

· Sector erase architecture

· Low power consumption

- Active current: 30 mA (typ.)

- Standby current: 1 mA (typ.)

· End of program detection

- 8 uniform sectors of 64K bytes each

- Any combination of sectors can be erased

- Supports full chip erase

- Software method: Toggle bit/Data polling

· TTL compatible I/O

· JEDEC standard byte-wide pinouts

· Sector protection

· Available packages: 32-pin PLCC, 32-pin

TSOP and 32-pin PDIP

- Sectors can be locked via programmer

· Read access time: 55/70 ns
