Am29SL160C

16 Megabit (2 M x 8-Bit/1 M x 16-Bit)

CMOS 1.8 Volt-only Super Low Voltage Flash Memory

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

■

Secured Silicon (SecSi) Sector: 256-byte sector

— Factory locked and identifiable: 16 bytes 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: Customer may program own

custom data. Once locked, data cannot be changed

■

Zero Power Operation

— Sophisticated power management circuits reduce

power consumed during inactive periods to nearly

zero

■

Package options

— 48-ball FBGA

— 48-pin TSOP

■

Top or bottom boot block

■

Manufactured on 0.32 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: 8 µs/word typical using Accelerate

■

Ultra low power consumption (typical values)

— 1 mA active read current at 1 MHz

— 5 mA active read current at 5 MHz

— 1 µA 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

same bank

■

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 reading array data

■

WP#/ACC input pin

— Write protect (WP#) function allows protection of two

outermost boot sectors, regardless of sector protect status

— Acceleration (ACC) function accelerates program

timing

■

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
