DATA SHEET

Am29LV320MT/B

32 Megabit (2 M x 16-Bit/4 M x 8-Bit) MirrorBit

™

3.0 Volt-only Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

■ Single power supply operation

— 3 V for read, erase, and program operations

■ Manufactured on 0.23 µm MirrorBit process

technology

■ Secured Silicon Sector region

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

identification through an 8-word/16-byte random

Electronic Serial Number, accessible through a

command sequence

— May be programmed and locked at the factory or by

the customer

■ 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

single-power supply flash, and superior inadvertent

write protection

■ Minimum 100,000 erase cycle guarantee per sector

■ 20-year data retention at 125°C

PERFORMANCE CHARACTERISTICS

■ 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

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

programming time for multiple-word/byte updates

— 4-word/8-byte page read buffer

— 16-word/32-byte write buffer

■ 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 & HARDWARE FEATURES

■ Software features

— Program Suspend & Resume: read other sectors

before programming operation is completed

— Erase Suspend & Resume: read/program other

sectors before an erase operation is completed

— Data# polling & toggle bits provide status

— Unlock Bypass Program command reduces overall

multiple-word programming time

— CFI (Common Flash Interface) compliant: allows host

system to identify and accommodate multiple flash

devices

■ Hardware features

— Sector Group Protection: hardware-level method of

preventing write operations within a sector group

— Temporary Sector Unprotect: V

changing code in locked sectors

— WP#/ACC input:

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

— Hardware reset input (RESET#) resets device

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

erase cycle completion
