256 Megabit, 128 Megabit, 64 Megabit, and 32 Megabit, 3.0 Volt-only Page Mode Flash Memory featuring 0.23 μm MirrorBit Process Technology

General Description

The S29GL256/128/064/032M family of devices are 3.0 V single power Flash memory manufactured using 0.23 μm MirrorBit technology. The S29GL256M is a 256?Mbit, organized as 16,777,216 words or 33,554,432 bytes. The S29GL128M is a 128 Mbit, organized as 8,388,608 words or 16,777,216 bytes. The S29GL064M is a 64 Mbit, organized as 4,194,304 words or 8,388,608 bytes. The S29GL032M is a 32 Mbit, organized as 2,097,152 words or 4,194,304 bytes. Depending on the model number, the devices have an 8-bit wide data bus only, 16-bit wide data bus only, or a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The devices can be programmed either in the host system or in standard EPROM programmers.

Distinctive Characteristics

Architectural Advantages

■ Single power supply operation

— 3 volt 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

— 256 Mb: 512 32-Kword (64 Kbyte) sectors

— 128 Mb: 256 32-Kword (64 Kbyte) sectors

— 64 Mb (uniform sector models): 128 32-Kword (64-Kbyte) sectors or 128 32 Kword sectors

— 64 Mb (boot sector models): 127 32-Kword (64-Kbyte) sectors + 8 4Kword (8Kbyte) boot sectors

— 32 Mb (uniform sector models): 64 32-Kword (64-Kbyte) sectors of 64 32-Kword sectors

— 32 Mb (boot sector models): 63 32-Kword (64 Kbyte) sectors + 8 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

■ 100,000 erase cycles typical per sector

■ 20-year data retention typical

Performance Characteristics

■ High performance

— 90 ns access time (128 Mb, 64 Mb, 32 Mb), 100 ns access time (256 Mb)

— 4-word/8-byte page read buffer

— 25 ns page read times (128 Mb, 64 Mb, 32 Mb)

— 30 ns page read times (256 Mb)

— 16-word/32-byte write buffer

— 16-word/32-byte write buffer reduces overall programming time for multiple-word updates

■ Low power consumption (typical values at 3.0 V, 5 MHz)

— 18 mA typical active read current (64 Mb, 32 Mb)

— 25 mA typical active read current (256 Mb, 128 Mb)

— 50 mA typical erase/program current

— 1 μA typical standby mode current

■ Package options

— 40-pin TSOP

— 48-pin TSOP

— 56-pin TSOP

— 64-ball Fortified BGA

— 48-ball fine-pitch BGA

— 63-ball fine-pitch 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

— CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices

— Unlock Bypass Program command reduces overall multiple-word programming time

■ Hardware features

— Sector Group Protection: hardware-level method of preventing write operations within a sector group

— Temporary Sector Unprotect: VID-level method of charging code in locked sectors

— WP#/ACC input accelerates programming time (when high voltage is applied) for greater throughput during system production. Protects first or last sector regardless of sector protection settings on uniform sector models

— Hardware reset input (RESET#) resets device

— Ready/Busy# output (RY/BY#) detects program or erase cycle completion
