W29C020-12B规格书详情
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.
