PRELIMINARY  
Am29F400B  
4 Megabit (512 K x 8-Bit/256 K x 16-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  
Manufactured on 0.35 µm process technology  
— Compatible with 0.5 µm Am29F400 device  
— Embedded Program algorithm automatically  
writes and verifies data at specified addresses  
High performance  
— Access times as fast as 55 ns  
Minimum 1,000,000 program/erase cycles per  
Low power consumption (typical values at 5  
sector guaranteed  
MHz)  
Package option  
— 48-pin TSOP  
— 44-pin SO  
— 1 µA standby mode current  
— 20 mA read current (byte mode)  
— 28 mA read current (word mode)  
— 30 mA program/erase current  
Compatibility with JEDEC standards  
— Pinout and software compatible with single-  
power-supply Flash  
Flexible sector architecture  
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and  
seven 64 Kbyte sectors (byte mode)  
— Superior inadvertent write protection  
Data# Polling and toggle bits  
— One 8 Kword, two 4 Kword, one 16 Kword, and  
seven 32 Kword sectors (word mode)  
— Provides a software method of detecting  
program or erase operation completion  
— Supports full chip erase  
Ready/Busy# pin (RY/BY#)  
— Sector Protection features:  
— Provides a hardware method of detecting  
program or erase cycle completion  
A hardware method of locking a sector to  
prevent any program or erase operations within  
that sector  
Erase Suspend/Erase Resume  
Sectors can be locked via programming  
equipment  
— Suspends an erase operation to read data from,  
or program data to, a sector that is not being  
erased, then resumes the erase operation  
Temporary Sector Unprotect feature allows code  
changes in previously locked sectors  
Hardware reset pin (RESET#)  
— Hardware method to reset the device to reading  
array data
