Am29LV320D

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

CMOS 3.0 Volt-only, Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

■

Secured Silicon (SecSiTM Sector)

— 64 Kbyte Sector Size; Replacement/substitute

devices (such as Mirrorbit

™) have 256 bytes.

— Factory locked and identifiable: 16 bytes (8

words) available for secure, random factory

Electronic Serial Number; verifiable as factory

locked through autoselect function.

ExpressFlash option allows entire sector to be

available for factory-secured data

— Customer lockable: Can be programmed once

and then permanently locked after being

shipped from AMD

■

Zero Power Operation

— Sophisticated power management circuits

reduce power consumed during inactive

periods to nearly zero.

■

Package options

—48-pin TSOP

— 48-ball FBGA

■

Sector Architecture

— Eight 8 Kbyte sectors

— Sixty-three 64 Kbyte sectors

■

Top or bottom boot block

■

Manufactured on 0.23 µm process

technology

■

Compatible with JEDEC standards

— Pinout and software compatible with

single-power-supply flash standard

PERFORMANCE CHARACTERISTICS

■

High performance

— Access time as fast 90 ns

— Program time: 7µs/word typical utilizing

Accelerate function

■

Ultra low power consumption (typical

values)

— 2 mA active read current at 1 MHz

— 10 mA active read current at 5 MHz

— 200 nA in standby or automatic sleep mode

■

Minimum 1 million erase cycles guaranteed

per sector

■

20 Year data retention at 125°C

— Reliable operation for the life of the system

SOFTWARE FEATURES

■

Supports Common Flash Memory Interface

(CFI)

■

Erase Suspend/Erase Resume

— Suspends erase operations to allow

programming in non-suspended sectors

■

Data# Polling and Toggle Bits

— Provides a software method of detecting the

status of program or erase cycles

■

Unlock Bypass Program command

— Reduces overall programming time when

issuing multiple program command sequences

HARDWARE FEATURES

■

Any combination of sectors can be erased

■

Ready/Busy# output (RY/BY#)

— Hardware method for detecting program or

erase cycle completion

■

Hardware reset pin (RESET#)

— Hardware method of resetting the internal

state machine to the read mode

■

WP#/ACC input pin

— Write protect (WP#) function allows protection

of two outermost boot sectors, regardless of

sector protect status

— Acceleration (ACC) function provides

accelerated program times

■

Sector protection

— Hardware method of locking a sector, either

in-system or using programming equipment,

to prevent any program or erase operation

within that sector

— Temporary Sector Unprotect allows changing

data in protected sectors in-system
