W19B320BT/B DATASHEET
1. GENERAL DESCRIPTION
The W19B320BT/B is a 32Mbit, 2.7~3.6-volt single bank CMOS flash memory organized as 4M x 8 or
2M × 16 bits. The word-wide (× 16) data appears on DQ15-DQ0, and byte-wide (x 8) data appears on
DQ7-DQ0. The device can be programmed and erased in-system with a standard 3.0-volt power
supply. A 12-volt V
is not required. The unique cell architecture of the W19B320BT/B results in fast
PP
program/erase operations with extremely low current consumption (compared to other comparable 3-
volt flash memory products). The device can also be programmed and erased by using standard
EPROM programmers.
