GENERAL DESCRIPTION
The Am29LV320MH/L is a 32 Mbit, 3.0 volt single power supply flash memory device organized as 2,097,152 words or 4,194,304 bytes. The device has an 8-bit/16-bit bus and can be programmed either in the host system or in standard EPROM programmers.
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 VIO pin; operates
from 1.65 to 3.6 V
◾ Manufactured on 0.23 µm 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
— Sixty-four 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
— 15 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)
— 13 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
