1. Description  
AT29C040A  
The AT29C040A is a 5-volt only in-system Flash Programmable and Erasable Read  
Only Memory (PEROM). Its 4 megabits of memory is organized as 524,288 words by  
8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS EEPROM technology,  
the device offers access times up to 90 ns, and a low 220 mW power dissipation.  
When the device is deselected, the CMOS standby current is less than 100 µA. The  
device endurance is such that any sector can typically be written to in excess of  
10,000 times. The programming algorithm is compatible with other devices in Atmel’s  
5-volt only Flash family.  
To allow for simple in-system reprogrammability, the AT29C040A does not require  
high input voltages for programming. Five-volt-only commands determine the opera-  
tion of the device. Reading data out of the device is similar to reading from an  
EPROM. Reprogramming the AT29C040A is performed on a sector basis; 256 bytes  
of data are loaded into the device and then simultaneously programmed.  
During a reprogram cycle, the address locations and 256 bytes of data are internally  
latched, freeing the address and data bus for other operations. Following the initiation  
of a program cycle, the device will automatically erase the sector and then program  
the latched data using an internal control timer. The end of a program cycle can be  
detected by DATA polling of I/O7. Once the end of a program cycle has been  
detected, a new access for a read or program can begin.
