Datasheet  
DATASHEET  
Distinctive Characteristics  
„
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  
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  
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  
— 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  
— Unlock Bypass Program command reduces overall  
multiple-word programming time  
— 64Mb (boot sector models): 127 32 Kword (64 Kbyte)  
sectors + 8 4Kword (8Kbyte) boot sectors  
„
Hardware features  
— 32Mb (uniform sector models): 64 32Kword (64  
Kbyte) sectors of 64 32Kword sectors  
— 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  
— 32Mb (boot sector models): 63 32Kword (64 Kbyte)  
sectors + 8 4Kword (8Kbyte) boot sectors  
„
Compatibility with JEDEC standards  
— Provides pinout and software compatibility for single-  
power supply flash, and superior inadvertent write  
protection  
— 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  
„
„
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
