Preliminary W49F002A
256K
× 8 CMOS FLASH MEMORY
Publication Release Date: September 12, 2001

Revision A1
GENERAL DESCRIPTION
The W49F002A is a 2-megabit, 5-volt only CMOS flash memory organized as 256K
× 8 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 W49F002A 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
5-volt Erase
5-volt Program
Fast program operation:
Byte-by-byte programming: 35 S (typ.)
Fast erase operation: 100 mS (typ.)
Fast read access time: 120 nS
Ten-year data retention
Hardware data protection
One 16K byte Boot Block with Lockout
protection
Typical page write (erase/program) cycles:
10
100
Two 8K byte parameter blocks
Two main memory blocks (96K, 128K) Bytes
Low power consumption
Active current: 25 mA (typ.)
Standby current: 20 A (typ.)
Automatic program and erase timing with
internal VPP generation
End of program or erase detection
Toggle bit
Data polling
Latched address and data
TTL compatible I/O
JEDEC standard byte-wide pinouts
Available packages: 32-pin DIP and PLCC
