AT29BV010A  
1. Description  
The AT29BV010A is a 2.7-volt only in-system Flash Programmable and Erasable  
Read Only Memory (Flash). Its 1 megabit of memory is organized as 131,072 words  
by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS EEPROM technol-  
ogy, the device offers access times to 120 ns, and a low 54 mW power dissipation.  
When the device is deselected, the CMOS standby current is less than 50 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  
Low Voltage Flash family of products.  
To allow for simple in-system reprogrammability, the AT29BV010A does not require  
high input voltages for programming. The device can be operated with a single 2.7V to  
3.6V supply. Reading data out of the device is similar to reading from an EPROM.  
Reprogramming the AT29BV010A is performed on a sector basis; 128 bytes of data  
are loaded into the device and then simultaneously programmed.  
During a reprogram cycle, the address locations and 128 bytes of data are captured at  
microprocessor speed and internally latched, freeing the address and data bus for  
other operations. Following the initiation of a program cycle, the device will automati-  
cally 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.
