1 Gigabit, 512 Megabit, 256 Megabit and 128 Megabit 3.0 Volt-only Page Mode Flash Memory featuring 90 nm MirrorBit Process Technology

General Description

The Spansion S29GL01G/512/256/128P are Mirrorbit? Flash products fabricated on 90 nm process technology. These devices offer a fast page access time of 25 ns with a corresponding random access time as fast as 90 ns. They feature a Write Buffer that allows a maximum of 32 words/64 bytes to be programmed in one operation, resulting in faster effective programming time than standard programming algorithms. This makes these devices ideal for today’s embedded applications that require higher density, better performance and lower power consumption.

Distinctive Characteristics

■ Single 3V read/program/erase (2.7-3.6 V)

■ Enhanced VersatileI/O? control

– All input levels (address, control, and DQ input levels) and outputs are determined by voltage on VIO input. VIO range is 1.65 to VCC

■ 90 nm MirrorBit process technology

■ 8-word/16-byte page read buffer

■ 32-word/64-byte write buffer reduces overall programming time for multiple-word updates

■? Secured Silicon Sector region

– 128-word/256-byte sector for permanent, secure identification through an 8-word/16-byte random Electronic Serial Number

– Can be programmed and locked at the factory or by the customer

■ Uniform 64 Kword/128 Kbyte Sector Architecture

– S29GL01GP: One thousand twenty-four sectors

– S29GL512P: Five hundred twelve sectors

– S29GL256P: Two hundred fifty-six sectors

– S29GL128P: One hundred twenty-eight sectors

■ 100,000 erase cycles per sector typical

■ 20-year data retention typical

■ Offered Packages

– 56-pin TSOP

– 64-ball Fortified BGA

■ Suspend and Resume commands for Program and Erase operations

■ Write operation status bits indicate program and erase operation completion

■ Unlock Bypass Program command to reduce programming time

■ Support for CFI (Common Flash Interface)

■ Persistent and Password methods of Advanced Sector Protection

■ WP#/ACC input

– Accelerates programming time (when VHH is applied) for greater throughput during system production

– Protects first or last sector regardless of sector protection settings

■ Hardware reset input (RESET#) resets device

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