4 Megabit (512 K x 8-Bit/256 K x 16-Bit)
CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
I
Single power supply operation
— 5.0 volt-only operation for read, erase, and
program operations
— Minimizes system level requirements
I
Manufactured on 0.35 μm process technology
— Compatible with 0.5 μm Am29F400 device
I
High performance
— Access times as fast as 55 ns
I
Low power consumption (typical values at 5
MHz)
— 1 μA standby mode current
— 20 mA read current (byte mode)
— 28 mA read current (word mode)
— 30 mA program/erase current
I
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
I
Top or bottom boot block configurations
available
I
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
I
Minimum 1,000,000 program/erase cycles per
sector guaranteed
I
Package option
— 48-pin TSOP
— 44-pin SO
I
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power-supply Flash
— Superior inadvertent write protection
I
Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
I
Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
I
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
I
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
