3.0 Volt-only Uniform Sector Flash Memory
with VersatileI/O™ Control
This product has been retired and is not available for designs. For new and current designs, S29GL064A supersedes Am29LV640M H/L and is the factory-recommended migration path.
Please refer to the S29GL064A datasheet for specifications and ordering information. Availability of this document is retained for reference and historical purposes only.
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
„ Single power supply operation
— 3 V for read, erase, and program operations
„ VersatileI/O™ control
— Device generates data output voltages and tolerates
data input voltages on the DQ inputs/outputs as
determined by the voltage on the V_IO pin; operates
from 1.65 to 3.6 V
„ Manufactured on 0.23 µm 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
— One hundred twenty-eight 32 Kword/64-Kbyte sectors
„ Compatibility with JEDEC standards
— Provides pinout and software compatibility for
single-power supply flash, and superior inadvertent
write protection
„ Minimum 100,000 erase cycle guarantee per sector
„ 20-year data retention at 125°C
PERFORMANCE CHARACTERISTICS
„ High performance
— 90 ns access time
— 25 ns page read times
— 0.5 s typical sector erase time
— 22 µs typical effective write buffer word programming
time: 16-word/32-byte write buffer reduces overall
programming time for multiple-word/byte updates
— 4-word/8-byte page read buffer
— 16-word/32-byte write buffer
„ Low power consumption (typical values at 3.0 V, 5
MHz)
— 30 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 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
— 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
HARDWARE FEATURES
— Sector Group Protection: hardware-level method of
preventing write operations within a sector group
— Temporary Sector Unprotect: V_ID-level method of
changing code in locked sectors
— WP#/ACC input:
Write Protect input (WP#) protects first or last sector
regardless of sector protection settings
ACC (high voltage) accelerates programming time for
higher throughput during system production
— Hardware reset input (RESET#) resets device
— Ready/Busy# output (RY/BY#) indicates program or
erase cycle completion
