DISTINCTIVE CHARACTERISTICS

This Data Sheet states AMD’s current technical specifications regarding the Products described herein. This Data

Sheet may be revised by subsequent versions or modifications due to changes in technical specifications.

Single power supply operation

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

— Regulated voltage range: 3.0 to 3.6 volt read and

Manufactured on 0.32 µm process technology

— Compatible with 0.5 µm Am29LV400 device

High performance

— Full voltage range: access times as fast as 70 ns

— Regulated voltage range: access times as fast as

Ultra low power consumption (typical values at

5 MHz)

— 200 nA Automatic Sleep mode current

— One 8 Kword, two 4 Kword, one 16 Kword, and

— Supports full chip erase

— Sector Protection features:

Unlock Bypass Program Command

— Reduces overall programming time when issuing

operations for battery-powered applications

write operations for compatibility with high

performance 3.3 volt microprocessors

55 ns

seven 64 Kbyte sectors (byte mode)

seven 32 Kword sectors (word mode)

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

multiple program command sequences

Top or bottom boot block configurations

available

Embedded Algorithms

— Embedded Erase algorithm automatically

— Embedded Program algorithm automatically

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

— 48-ball FBGA

— 48-pin TSOP

— 44-pin SO

Compatibility with JEDEC standards

— Pinout and software compatible with single-

— Superior inadvertent write protection

Data# Polling and toggle bits

— Provides a software method of detecting program

Ready/Busy# pin (RY/BY#)

— Provides a hardware method of detecting

Erase Suspend/Erase Resume

— Suspends an erase operation to read data from,

Hardware reset pin (RESET#)

— Hardware method to reset the device to reading

preprograms and erases the entire chip or any

combination of designated sectors

writes and verifies data at specified addresses

power supply Flash

or erase operation completion

program or erase cycle completion

or program data to, a sector that is not being

erased, then resumes the erase operation
