The W39L020 is a 2Mbit, 3.3-volt only CMOS flash memory organized as 256K x 8 bits. For flexible erase capability, the 2Mbits of data are divided into 4 uniform sectors of 64 Kbytes, which are composed of 16 smaller even pages with 4 Kbytes. The byte-wide (x 8) data appears on DQ7 - DQ0. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is not required. The unique cell architecture of the W39L020 results in fast program/erase operations with extremely low current consumption (compared to other comparable 3.3-volt flash memory products). The device can also be programmed and erased by using standard EPROM programmers. |
