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
VPP 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

· Two 8 KB boot blocks with lockout
· Whole chip cycling: 10K (typ.)
· Read access time: 70/90/120 nS
· Twenty-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
