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
