GENERAL DESCRIPTION

The W29C020 is a 2-megabit, 5-volt only CMOS flash memory organized as 256K x 8 bits. The device can be written (erased and programmed) in-system with a standard 5V power supply. A 12-volt VPPis not required. The unique cell architecture of the W29C020 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

· Fast page-write operations

- 128 bytes per page

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

- Effective byte-write (erase/program) cycle time: 39 mS

- Optional software-protected data write

· Fast chip-erase operation: 50 mS

· Two 8 KB boot blocks with lockout

· Typical page write (erase/program) cycles: 100/1K/10K

· Read access time: 70/90/120 nS

· Ten-year data retention

· Software and hardware data protection

· Low power consumption

- Active current: 25 mA (typ.)

- Standby current: 20 mA (typ.)

· Automatic write (erase/program) timing with internal VPP generation

· End of write (erase/program) detection

- Toggle bit

- Data polling

· Latched address and data

· All inputs and outputs directly TTL compatible

· JEDEC standard byte-wide pinouts

· Available packages: 32-pin 600 mil DIP, 450 mil SOP, TSOP, and 32-pin PLCC
