S29AL004D Known Good Die  
4 Megabit (512K x 8-Bit/256 K x 16-Bit)  
CMOS 3.0 Volt-only, Boot Sector Flash Memory  
Data Sheet Supplement  
Distinctive Characteristics  
„ Single power supply operation  
„ Embedded Algorithms  
2.7 to 3.6 V for read, program, and erase operations  
Embedded Erase algorithm automatically  
preprograms and erases the entire chip or any  
combination of designated sectors  
„ Manufactured on 0.20µm process technology  
„ High performance  
Embedded Program algorithm automatically writes  
and verifies data at specified addresses  
Access times as fast as 70 ns  
„ Ultra low power consumption (typical values  
„ Minimum one million write cycle guarantee  
per sector  
„ Compatibility with JEDEC standards  
at 5 MHz)  
200 nA Automatic Sleep mode current  
200 nA standby mode current  
9 mA read current  
Pinout and software compatible with single-power  
supply Flash  
20 mA program/erase current  
Superior inadvertent write protection  
„ Flexible sector architecture  
„ Data# Polling and toggle bits  
One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and seven  
64 Kbyte sectors (byte mode)  
Provides a software method of detecting program or  
erase operation completion  
One 8 Kword, two 4 Kword, one 16 Kword, and seven  
32 Kword sectors (word mode)  
„ Ready/Busy# pin (RY/BY#)  
Provides a hardware method of detecting program or  
erase cycle completion  
Supports full chip erase  
Sector Protection features:  
„ Erase Suspend/Erase Resume  
„ A hardware method of locking a sector to  
prevent any program or erase operations  
within that sector  
Suspends an erase operation to read data from, or  
program data to, a sector that is not being erased,  
then resumes the erase operation  
Sectors can be locked in-system or via programming  
equipment  
„ Hardware reset pin (RESET#)  
Temporary Sector Unprotect feature allows code  
changes in previously locked sectors  
Hardware method to reset the device to reading array  
data  
„ 20-year data retention at 125°C  
„ Unlock Bypass Program Command  
Reduces overall programming time when issuing  
multiple program command sequences  
Reliable operation for the life of the system  
„ Tested to data sheet specifications at  
„ Top or bottom boot block configurations  
temperature  
available  
„ Quality and reliability levels equivalent to  
standard packaged components
