INFORMATION

S29AL016M

16 Megabit (M x 16-Bit)

3.0 Volt-only Boot Sector Flash Memory

Featuring MirrorBitTM Technology

MCP Flash Module

Distinctive Characteristics

Architectural Advantages

Single power supply operation

— 3 V for read, erase, and program operations

Manufactured on 0.23 µm MirrorBitTM process

technology

SecSiTM (Secured Silicon) Sector region

— 128-word sector for permanent, secure identification

through an 8-word random Electronic Serial Number,

accessible through a command sequence

— May be programmed and locked at the factory or by

the customer

Flexible sector architecture

— One 8 Kword, two 4 Kword, one 16 Kword, and thirty-

one 32 Kword sectors (word mode)

Compatibility with JEDEC standards

— Provides pinout and software compatibility for single-

power supply flash, and superior inadvertent write

protection

Top or bottom boot block configurations available

100,000 erase cycle typical per sector

20-year typical data retention

Performance Characteristics

High performance

— 90/100 ns access time

— 0.7 s typical sector erase time

Low power consumption (typical values at 5 MHz)

— 400 nA standby mode current

— 15 mA read current

— 40 mA program/erase current

— 400 nA Automatic Sleep mode current

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 Protection: hardware-level method of

preventing write operations within a sector

— Temporary Sector Unprotect: VID-level method of

changing code in locked sectors

— Hardware reset input (RESET#) resets device

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

erase cycle completion
