Distinctive Characteristics
Architectural Advantages
Single pow er supply operation
— 3 volt read, erase, and program operations
Enhanced VersatileI / O
 control
— All input levels (address, control, and DQ input levels) 
and outputs are determined by voltage on V
IO
 input. 
V
IO
 range is 1.65 to V
CC
Manufactured on 110 nm MirrorBit process 
technology
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
— S29GL512N: Five hundred twelve 64 Kword (128 
Kbyte) sectors
— S29GL256N: Two hundred fifty-six 64 Kword (128 
Kbyte) sectors
— S29GL128N: One hundred twenty-eight 64 Kword 
(128 Kbyte) sectors
Compatibility w ith J EDEC standards
— Provides pinout and software compatibility for 
single-power supply flash, and superior inadvertent 
write protection
100,000 erase cycles per sector typical
20-year data retention typical
Performance Characteristics
High performance
— 90 ns access time (S29GL128N, S29GL256N)
— 100 ns (S29GL512N)
— 8-word/16-byte page read buffer
— 25 ns page read times
— 16-word/32-byte write buffer reduces overall 
programming time for multiple-word updates
Low  pow er consumption ( typical values at 3.0 V, 5 
MHz)
— 25 mA typical active read current; 
— 50 mA typical erase/program current
— 1 μA typical standby mode current
Package options
— 56-pin TSOP
— 64-ball Fortified BGA 
Software & Hardware Features
Softw are features
— Program Suspend and Resume: read other sectors 
before programming operation is completed
— Erase Suspend and Resume: read/program other 
sectors before an erase operation is completed
— Data# polling and toggle bits provide status
— Unlock Bypass Program command reduces overall 
multiple-word programming time 
— CFI (Common Flash Interface) compliant: allows host 
system to identify and accommodate multiple flash 
devices
Hardw are features
— Advanced Sector 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
— Hardware reset input (RESET#) resets device
— Ready/Busy# output (RY/BY#) detects program or 
erase cycle completion
