Preliminary W49F201
128K
× 16 CMOS FLASH MEMORY
Publication Release Date: June 1999
- 1 -
Revision A1
GENERAL DESCRIPTION
The W49F201 is a 2-megabit, 5-volt only CMOS flash memory organized as 128K
× 16 bits. The
device can be programmed and erased in-system with a standard 5V power supply. A 12-volt VPP is
not required. The unique cell architecture of the W49F201 results in fast program/erase operations
with extremely low current consumption (compared to other comparable 5-volt flash memory
products). The device can also be programmed and erased using standard EPROM programmers.
FEATURES
Single 5-volt operations:
− 5-volt Read/Erase/Program
Fast Program operation:
− Word-by-Word programming: 50 µS (max.)
Fast Erase operation: 60 mS (typ.)
Fast Read access time: 45/55 nS
Endurance: 1K/10K cycles (typ.)
Ten-year data retention
Hardware data protection
