4 Megabit (512 K x 8-Bit/256 K x 16-Bit)
CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
s Single power supply operation
— 5.0 volt-only operation for read, erase, and
program operations
— Minimizes system level requirements
s Manufactured on 0.32 m process technology
— Compatible with 0.5 m Am29F400 device
s High performance
— Access times as fast as 45 ns
s Low power consumption (typical values at
5 MHz)
— 1 A standby mode current
— 20 mA read current (byte mode)
— 28 mA read current (word mode)
— 30 mA program/erase current
s Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
seven 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
seven 32 Kword sectors (word mode)
— 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 previously locked sectors
s Top or bottom boot block configurations available
s Embedded Algorithms
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
s Minimum 1,000,000 program/erase cycles per
sector guaranteed
s 20-year data retention at 125
°C
— Reliable operation for the life of the system
s Package option
— 48-pin TSOP
— 44-pin SO
— Known Good Die (KGD)
(see publication number 21258)
s Compatibility with JEDEC standards
— Pinout and software compatible with single-
power-supply Flash
— Superior inadvertent write protection
s Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
s Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
s 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
s Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
