DATA SHEET
Am29F002B/Am29F002NB
2 Megabit (256 K x 8-Bit)
CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
■ Embedded Algorithms
— 5.0 Volt-only operation for read, erase, and
program operations
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Minimizes system level requirements
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
■ Manufactured on 0.32 µm process technology
— Compatible with 0.5 µm Am29F002 device
■ Minimum 1,000,000 write cycle guarantee per
■ High performance
sector
— Access times as fast as 55 ns
■ 20-year data retention at 125°C
— Reliable operation for the life of the system
■ Package option
■ Low power consumption (typical values at
5 MHz)
— 1 µA standby mode current
— 20 mA read current
— 32-pin PDIP
— 32-pin TSOP
— 30 mA program/erase current
— 32-pin PLCC
■ Flexible sector architecture
■ Compatibility with JEDEC standards
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors
— Pinout and software compatible with
single-power supply Flash
— Supports full chip erase
— Superior inadvertent write protection
— Sector Protection features:
■ Data# Polling and toggle bits
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
— Provides a software method of detecting
program or erase operation completion
Sectors can be locked via programming equipment
■ Erase Suspend/Erase Resume
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
■ Top or bottom boot block configurations available
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data (not available on Am29F002NB)
