Product Description
The AT49BP1604(T) is a 2.7 volt 16-megabit Flash memory. The memory is divided
into 40 blocks for erase operations. It’s synchronous architecture allows fast sequen-
tial “burst” accesses of 25 ns after an initial random access of 100 ns. The 16 data
lines are multiplexed with 16 address lines (A0-A15) to reduce pin count. Four
address lines (A16-A19) are not multiplexed. This device can be read or repro-
