PERFORMANCE 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

— 3 V for read, erase, and program operations

Manufactured on 0.23 µm MirrorBit process

technology

SecSi

— 128-word/256-byte sector for permanent, secure

— May be programmed and locked at the factory or by

Flexible sector architecture

— Sixty-three 32 Kword/64-Kbyte sectors

— Eight 4 Kword/8 Kbyte boot sectors

Compatibility with JEDEC standards

— Provides pinout and software compatibility for

Minimum 100,000 erase cycle guarantee per sector

20-year data retention at 125 C

High performance

— 90 ns access time

— 25 ns page read times

— 0.5 s typical sector erase time

— 15 µs typical effective write buffer word programming

— 4-word/8-byte page read buffer

— 16-word/32-byte write buffer

identification through an 8-word/16-byte random

Electronic Serial Number, accessible through a

command sequence

the customer

single-power supply flash, and superior inadvertent

write protection

time: 16-word/32-byte write buffer reduces overall

programming time for multiple-word/byte updates

SOFTWARE & HARDWARE FEATURES

Low power consumption (typical values at 3.0 V, 5

MHz)

— 13 mA typical active read current

— 50 mA typical erase/program current

— 1 µA typical standby mode current

Package options

— 48-pin TSOP

— 48-ball Fine-pitch BGA

— 64-ball Fortified BGA

Software features

— Program Suspend & Resume: read other sectors

— Erase Suspend & Resume: read/program other

— Data# polling & toggle bits provide status

— Unlock Bypass Program command reduces overall

— CFI (Common Flash Interface) compliant: allows host

Hardware features

— Sector Group Protection: hardware-level method of

— Temporary Sector Unprotect: V

— WP#/ACC input:

— Hardware reset input (RESET#) resets device

— Ready/Busy# output (RY/BY#) indicates program or

before programming operation is completed

sectors before an erase operation is completed

multiple-word programming time

system to identify and accommodate multiple flash

devices

preventing write operations within a sector group

changing code in locked sectors

Write Protect input (WP#) protects top or bottom two

sectors regardless of sector protection settings

ACC (high voltage) accelerates programming time for

higher throughput during system production
