W49F002U
256K × 8
CMOS FLASH MEMORY
GENERAL DESCRIPTION
The W49F002U 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 W49F002U 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 µS (typ.
)
• Fast Erase operation: 10...
