Am29DL400B

4 Megabit (512 K x 8-Bit/256 K x 16-Bit)

CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory

DISTINCTIVE CHARACTERISTICS

Simultaneous Read/Write operations

— Host system can program or erase in one bank,

— Zero latency between read and write operations

— Read-while-erase

— Read-while-program

Single power supply operation

— 2.7 to 3.6 volt read and write operations for

Manufactured on 0.35 µm process technology

High performance

— Access times as fast as 70 ns

Low current consumption (typical values

at 5 MHz)

— 7 mA active read current

— 21 mA active read-while-program or read-while-

— 17 mA active program-while-erase-suspended

— 200 nA in standby mode

— 200 nA in automatic sleep mode

— Standard t

Flexible sector architecture

— Two 16 Kword, two 8 Kword, four 4 Kword, and

— Two 32 Kbyte, two 16 Kbyte, four 8 Kbyte, and

— Any combination of sectors can be erased

— Supports full chip erase

Unlock Bypass Program Command

— Reduces overall programming time when

then immediately and simultaneously read from

the other bank
