Architectural Advantages
* Single power supply operation
- 3 volt read, erase, and program operations
* Manufactured on 0.23 um MirrorBit process technology
* SecSi™ (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
- 256Mb: 512 32 Kword (64 Kbyte) sectors
- 128Mb: 256 32 Kword (64 Kbyte) sectors
- 64Mb (uniform sector models): 128 32 Kword (64 Kbyte) sectors or 128 32 Kword sectors
- 64Mb (boot sector models): 127 32 Kword (64 Kbyte) sectors + 8 4Kword (8Kbyte) boot sectors
- 32Mb (uniform sector models): 64 32Kword (64 Kbyte) sectors of 64 32Kword sectors
- 32Mb (boot sector models): 63 32Kword (64 Kbyte) sectors + 8 4Kword (8Kbyte) boot sectors
* Compatibility with JEDEC standards
- Provides pinout and software compatibility for singlepower 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 (128Mb, 64Mb, 32Mb), 100 ns access time (256Mb)
- 4-word/8-byte page read buffer
- 25 ns page read times (128Mb, 64Mb, 32Mb)
- 30 ns page read times (256Mb)
- 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
