DATASHEET
Am29LV320MT/B
32 Megabit (2 M x 16-Bit/4 M x 8-Bit) MirrorBit铮?/div>
3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
鈻?/div>
Single power supply operation
鈥?3 V for read, erase, and program operations
鈻?/div>
Manufactured on 0.23 碌m MirrorBit process
technology
鈻?/div>
SecSi铮?(Secured Silicon) Sector region
鈥?128-word/256-byte sector for permanent, secure
identification through an 8-word/16-byte random
Electronic Serial Number, accessible through a
command sequence
鈥?May be programmed and locked at the factory or by
the customer
鈻?/div>
Flexible sector architecture
鈥?Sixty-three 32 Kword/64-Kbyte sectors
鈥?Eight 4 Kword/8 Kbyte boot sectors
鈻?/div>
Compatibility with JEDEC standards
鈥?Provides pinout and software compatibility for
single-power supply flash, and superior inadvertent
write protection
鈻?/div>
Minimum 100,000 erase cycle guarantee per sector
鈻?/div>
20-year data retention at 125掳C
PERFORMANCE CHARACTERISTICS
鈻?/div>
High performance
鈥?90 ns access time
鈥?25 ns page read times
鈥?0.5 s typical sector erase time
鈥?15 碌s typical effective write buffer word programming
time: 16-word/32-byte write buffer reduces overall
programming time for multiple-word/byte updates
鈥?4-word/8-byte page read buffer
鈥?16-word/32-byte write buffer
鈻?/div>
Low power consumption (typical values at 3.0 V, 5
MHz)
鈥?13 mA typical active read current
鈥?50 mA typical erase/program current
鈥?1 碌A typical standby mode current
鈻?/div>
Package options
鈥?48-pin TSOP
鈥?48-ball Fine-pitch BGA
鈥?64-ball Fortified BGA
SOFTWARE & HARDWARE FEATURES
鈻?/div>
Software features
鈥?Program Suspend & Resume: read other sectors
before programming operation is completed
鈥?Erase Suspend & Resume: read/program other
sectors before an erase operation is completed
鈥?Data# polling & toggle bits provide status
鈥?Unlock Bypass Program command reduces overall
multiple-word programming time
鈥?CFI (Common Flash Interface) compliant: allows host
system to identify and accommodate multiple flash
devices
鈻?/div>
Hardware features
鈥?Sector Group Protection: hardware-level method of
preventing write operations within a sector group
鈥?Temporary Sector Unprotect: V
ID
-level method of
changing code in locked sectors
鈥?WP#/ACC input:
Write Protect input (WP#) protects top or bottom two
sectors regardless of sector protection settings
ACC (high voltage) accelerates programming time for
higher throughput during system production
鈥?Hardware reset input (RESET#) resets device
鈥?Ready/Busy# output (RY/BY#) indicates program or
erase cycle completion
