Functional description

The AS29LV800 is an 8 megabit, 3.0 volt Flash memory organized as 1 Megabyte of 8 bits/512Kbytes of 16 bits each. For flexible erase and program capability, the 8 megabits of data is divided into nineteen sectors: one 16K, two 8K, one 32K, and fifteen 64k byte sectors; or one 8K, two 4K, one 16K, and fifteen 32K word sectors. The ×8 data appears on DQ0–DQ7; the ×16 data appears on DQ0–DQ15. The AS29LV800 is offered in JEDEC standard 48-pin TSOP and 44-pin SOP packages. This device is designed to be programmed and erased in-system with a single 3.0V VCC supply. The device can also be reprogrammed in standard EPROM programmers.
