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
