HY29F400A  
4 Megabit (512Kx8/256Kx16) 5 Volt-only Flash Memory  
KEY FEATURES  
5 Volt Read, Program, and Erase  
– Minimizes system-level power requirements  
High Performance  
– Access times as fast as 50 ns  
Low Power Consumption  
– 20 mA typical active read current in byte  
mode, 28 mA typical in word mode  
– 30 mA typical program/erase current  
– 5 µA maximum CMOS standby current  
Compatible with JEDEC Standards  
– Package, pinout and command-set  
compatible with the single-supply Flash  
device standard  
Sector Protection  
– Any combination of sectors may be locked  
to prevent program or erase operations  
within those sectors  
Temporary Sector Unprotect  
– Allows changes in locked sectors  
(requires high voltage on RESET# pin)  
Internal Erase Algorithm  
– Automatically erases a sector, any  
combination of sectors, or the entire chip  
Internal Programming Algorithm  
– Automatically programs and verifies data  
at a specified address  
– Provides superior inadvertent write  
protection  
Fast Program and Erase Times  
– Byte programming time: 7 µs typical  
– Sector erase time: 1.0 sec typical  
– Chip erase time: 11 sec typical  
Data# Polling and Toggle Status Bits  
– Provide software confirmation of  
completion of program or erase  
operations  
Ready/Busy# Output (RY/BY#)  
– Provides hardware confirmation of  
completion of program and erase  
operations  
Sector Erase Architecture  
– Boot sector architecture with top and  
bottom boot block options available  
– One 16 Kbyte, two 8 Kbyte, one 32 Kbyte  
and seven 64 Kbyte sectors in byte mode  
– One 8 Kword, two 4 Kword, one 16 Kword  
and seven 32 Kword sectors in word mode  
– A command can erase any combination of  
sectors  
– Supports full chip erase  
Erase Suspend/Resume  
100,000 Program/Erase Cycles Minimum  
Space Efficient Packaging  
– Available in industry-standard 44-pin  
PSOP and 48-pin TSOP and reverse  
TSOP packages  
Temporarily suspends a sector erase  
operation to allow data to be read from, or  
programmed into, any sector not being  
erased  
GENERAL DESCRIPTION  
LOGIC DIAGRAM  
The HY29F400A is a 4 Megabit, 5 volt only CMOS  
Flash memory organized as 524,288 (512K) bytes  
or 262,144 (256K) words. The device is offered in  
industry-standard 44-pin PSOP and 48-pin TSOP  
packages.

The HY29F400A can be programmed and erased  
in-system with a single 5-volt VCC supply. Internally  
generated and regulated voltages are provided for  
program and erase operations, so that the device  
does not require a high voltage power supply to  
perform those functions. The device can also be  
programmed in standard EPROM programmers.  
Access times as fast as 55 ns over the full operat-  
ing voltage range of 5.0 volts ± 10% are offered  
for timing compatibility with the zero wait state re-  
quirements of high speed microprocessors. A 55  
ns version operating over 5.0 volts ± 5% is also
