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

— 64 Kbyte Sector Size; Replacement/substitute

devices (such as Mirrorbit

— 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
