PRELIMINARY
Am29F002/Am29F002N
2 Megabit (256 K x 8-Bit)
CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
■ Top or bottom boot block configurations
available
— 5.0 Volt-only operation for read, erase, and
program operations
■ Embedded Algorithms
— Minimizes system level requirements
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
■ High performance
— Access times as fast as 55 ns
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
■ Low power consumption (typical values at 5
MHz)
■ Minimum 100,000 write cycle guarantee per
— 1 µA standby mode current
— 20 mA read current
sector
■ Package option
— 32-pin PDIP
— 32-pin TSOP
— 32-pin PLCC
— 30 mA program/erase current
■ Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors
■ Compatibility with JEDEC standards
— Supports full chip erase
— Pinout and software compatible with single-
power supply Flash
— Sector Protection features:
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
— Superior inadvertent write protection
■ Data# Polling and toggle bits
Sectors can be locked via programming
equipment
— Provides a software method of detecting
program or erase operation completion
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
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data (not available on Am29F002N)
