Am29F002/Am29F002N
2 Megabit (256 K x 8-Bit)
CMOS 5.0 Volt-onl y Boot Sec tor Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
— 5.0 Volt-only operation for read, erase, and
program operations
— Minimizes system level requirements
■ High performan ce
— Access times as fast as 55 ns
■ Low power consu mp tio n (typical values at 5
MHz)
— 1 µA standby mode current
— 20 mA read current
— 30 mA program/erase current
■ Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors
— Supports full chip erase
— Sector Protection features:
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
Sectors can be locked via programming
equipment
Temporary Sector Unprotect feature allows code
changes in prev iously locked sectors
■ Top or bottom boot block configurations
available
■ Embedded Algori thms
— Embedded Erase algorithm automatically
preprogr ams and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically
writes and verifies data at specif ied addresses
■ Minimum 100,000 write cycle guarantee per
sector
■ Package option
— 32-pin PDIP
— 32-pin TSOP
— 32-pin PLCC
■ Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
■ Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
■ Erase Suspend/Erase Resume
— Suspends an er ase operati on to read dat a from,
or progr am data to, a sector that is not being
erased, then res umes the erase operation
■ Hardware reset pin (RESET#)
— Hardware method t o reset the device t o reading
array data (not available on Am29F002N)
