Datasheet
DATASHEET
Distinctive Characteristics
Architectural Advantages
 Single power supply operation
â 3 volt read, erase, and program operations
 Manufactured on 0.23 um MirrorBit process
technology
 SecSi⢠(Secured Silicon) Sector region
â 128-word/256-byte sector for permanent, secure
identification through an 8-word/16-byte random
Electronic Serial Number, accessible through a
command sequence
â May be programmed and locked at the factory or by
the customer
 Flexible sector architecture
â 256Mb: 512 32 Kword (64 Kbyte) sectors
â 128Mb: 256 32 Kword (64 Kbyte) sectors
â 64Mb (uniform sector models): 128 32 Kword (64
Kbyte) sectors or 128 32 Kword sectors
â 64Mb (boot sector models): 127 32 Kword (64 Kbyte)
sectors + 8 4Kword (8Kbyte) boot sectors
â 32Mb (uniform sector models): 64 32Kword (64
Kbyte) sectors of 64 32Kword sectors
â 32Mb (boot sector models): 63 32Kword (64 Kbyte)
sectors + 8 4Kword (8Kbyte) boot sectors
 Compatibility with JEDEC standards
â 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
â 90 ns access time (128Mb, 64Mb, 32Mb),
100 ns access time (256Mb)
â 4-word/8-byte page read buffer
â 25 ns page read times (128Mb, 64Mb, 32Mb)
â 30 ns page read times (256Mb)
â 16-word/32-byte write buffer
â 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)
â 18 mA typical active read current (64 Mb, 32 Mb)
â 25 mA typical active read current (256 Mb, 128 Mb)
â 50 mA typical erase/program current
â 1 µA typical standby mode current
 Package options
â 40-pin TSOP
â 48-pin TSOP
â 56-pin TSOP
â 64-ball Fortified BGA
â 48-ball fine-pitch BGA
â 63-ball fine-pitch BGA
Software & Hardware Features
 Software features
â Program Suspend & Resume: read other sectors
before programming operation is completed
â Erase Suspend & Resume: read/program other
sectors before an erase operation is completed
â Data# polling & toggle bits provide status
â CFI (Common Flash Interface) compliant: allows host
system to identify and accommodate multiple flash
devices
â Unlock Bypass Program command reduces overall
multiple-word programming time
 Hardware features
â Sector Group Protection: hardware-level method of
preventing write operations within a sector group
â Temporary Sector Unprotect: VID-level method of
charging code in locked sectors
â 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
â Hardware reset input (RESET#) resets device
â Ready/Busy# output (RY/BY#) detects program or
erase cycle completion
