W29C020 - 256K x 8 CMOS FLASH MEMORY
The W29C020 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 W29C020 results in fast write (erase/program) operatio
W29C020 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 µS
* Optional software-protected data write
