DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

— Full voltage range: 2.7 to 3.6 volt read and write

operations for battery-powered applications

— Regulated voltage range: 3.0 to 3.6 volt read and

write operations and for compatibility with high

performance 3.3 volt microprocessors

■ Manufactured on 0.32 µm process technology

— Compatible with 0.5 µm Am29LV008 device

■ High performance

— Full voltage range: access times as fast as 90 ns

— Regulated voltage range: access times as fast as

70 ns

■ Ultra low power consumption (typical values at 5

MHz)

— 200 nA Automatic Sleep mode current

— 200 nA standby mode current

— 7 mA read current

— 15 mA program/erase current

■ Flexible sector architecture

— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and

fifteen 64 Kbyte sectors

— Supports full chip erase

— Sector Protection features:

A hardware method of locking a sector to prevent

any program or erase operations within that

sector

Sectors can be locked in-system or via

programming equipment

Temporary Sector Unprotect feature allows code

changes in previously locked sectors

■ Unlock Bypass Program Command

— Reduces overall programming time when issuing

multiple program command sequences

■ Top or bottom boot block configurations

available

■ Embedded Algorithms

— Embedded Erase algorithm automatically

preprograms and erases the entire chip or any

combination of designated sectors

— Embedded Program algorithm automatically

writes and verifies data at specified addresses

■ Minimum 1,000,000 write cycle guarantee per sector

■ 20-year data retention at 125°C

— Reliable operation for the life of the system

■ Package option

— 40-pin TSOP

■ Compatibility with JEDEC standards

— Pinout and software compatible with single-

power supply Flash

— Superior inadvertent write protection

■ Data# Polling and toggle bits

— Provides a software method of detecting program

or erase operation completion

■ Ready/Busy# pin (RY/BY#)

— Provides a hardware method of detecting

program or erase cycle completion

■ Erase Suspend/Erase Resume

— Suspends an erase operation to read data from,

or program data to, a sector that is not being

erased, then resumes the erase operation

■ Hardware reset pin (RESET#)

— Hardware method to reset the device to reading

array data
