W49L102P-70B

64K x 16 CMOS 3.3V FLASH MEMORY

Winbond 

Preliminary W49L102

64K × 16 CMOS 3.3V FLASH MEMORY

GENERAL DESCRIPTION

The W49L102 is a 1-megabit, 3.3-volt only CMOS flash memory organized as 64K × 16 bits. 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 W49L102 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 using standard EPROM programmers.
