W19B160BT/B DATA SHEET
1. GENERAL DESCRIPTION
The W19B160B is a 16Mbit, 2.7~3.6 volt CMOS flash memory organized as 2M
×
8 or 1M
×
16 bits.
For flexible erase capability, the 16Mbits of data are divided into one 16Kbyte, two 8Kbyte, one
32Kbyte, and thirty-one 64Kbyte sectors. The word-wide (× 16) data appears on DQ15-DQ0, and
byte-wide (× 8) data appears on DQ7−DQ0. The device can be programmed and erased in-system
with a standard 2.7~3.6V power supply. A 12-volt V
PP
is not required. The unique cell architecture of
the W19B160B results in fast program/erase operations with extremely low current consumption. The
device can also be programmed and erased by using standard EPROM programmers.
