W49F020T-90B - Brand New Winbond Electronics IC Chips
-
Description
The W49F020 is a 2-megabit, 5-volt only CMOS flash memory organized as 256K x 8 bits. It can be programmed and erased in-system with a standard 5V power supply, eliminating the need for a 12-volt VPP. The unique cell architecture of the W49F020 enables fast program/erase operations with extremely low current consumption compared to other comparable 5-volt flash memory products. Additionally, the device can also be programmed and erased using standard EPROM programmers.
