erations for battery-powered applications
Ultra low power consumption (typical values
at 5 MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 9 mA read current
— 20 mA program/erase current
Manufactured on 200 nm process technology
— Fully compatible with 0.23 µm Am29LV320D, 0.32 µm
Am29LV033C, and 0.33 µm MBM29LV320E devices
Flexible sector architecture
— Boot sector models: Eight 8-Kbyte sectors; sixty-
three 64-Kbyte sectors; top or bottom boot block
configurations available
— Uniform sector models: Sixty-four 64-Kbyte sectors
Cycling endurance: 1,000,000 cycles per
sector typical
Data retention: 20 years typical
Software Features
CFI (Common Flash Interface) compliant
— Provides device-specific information to the system,
allowing host software to easily reconfigure for
different Flash devices
Sector Protection features
— A hardware method of locking a sector to prevent any
program or erase operations within that sector
— Sectors can be locked in-system or via programming
equipment
— Temporary Sector Unprotect feature allows code
changes in previously locked sectors
Erase Suspend/Erase Resume
— Suspends an erase operation to read data from, or
program data to, a sector that is not being erased,
then resumes the erase operation
Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
Data# Polling and toggle bits
— Provides a software method of detecting program or
erase operation completion
— Unlock Bypass Program Command
Reduces overall programming time when issuing
multiple program command sequences
Secured Silicon Sector
— 128-word sector for permanent, secure identification
through an 8-word random Electronic Serial Number
— May be programmed and locked at the factory or by
the customer
— Accessible through a command sequence
Hardware Features
Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting program or
erase cycle completion
Compatibility with JEDEC standards
— Pinout and software compatible with single-power
supply Flash
— Superior inadvertent write protection
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading array
data
Package Options
48-ball FBGA
48-pin TSOP
40-pin TSOP
WP#/ACC input pin
— Write protect (WP#) function allows protection of two
outermost boot sectors (boot sector models only),
regardless of sector protect status
— Acceleration (ACC) function provides accelerated
program times
Performance Characteristics
High performance
— Access times as fast as 70 ns
