ADVANCE INFORMATION
Am29LV033MU
32 Megabit (4 M x 8-Bit) MirrorBit 3.0 Volt-only
Uniform Sector Flash Memory with VersatileI/O Control
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
■ Single power supply operation
— 3 volt read, erase, and program operations
■ VersatileI/O control
— Device generates and tolerates data voltages on CE#
and 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
— 256-byte sector for permanent, secure identification
through an 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 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
— 0.4 s typical sector erase time
— 3.0 µs typical write buffer byte programming time:
32-byte write buffer reduces overall programming
time for multiple-byte updates
— 8-byte read page buffer
— 32-byte write buffer
■ Low power consumption (typical values at 3.0 V,
5 MHz)
— 30 mA typical initial Page read current; 10 mA typical
intra-Page read current
— 50 mA typical erase/program current
— 1 µA typical standby mode current
■ Package options
— 40-pin TSOP
— 48-ball FBGA
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
— Unlock Bypass Program command reduces overall
multiple-byte programming time
— CFI (Common Flash Interface) compliant: allows host
system to identify and accommodate multiple flash
devices
■ Hardware features
— Sector Group Protection: hardware method of
preventing write operations within a sector group
— Temporary Sector Unprotect: V_ID-level method of
changing code in locked sectors
— ACC (high voltage) pin accelerates programming
time for higher throughput during system production
— Hardware reset pin (RESET#) resets device
— Ready/Busy# pin (RY/BY#) detects program or erase
cycle completion
