1. Description  
The AT29LV020 is a 3-volt-only in-system Flash programmable and erasable read  
only memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes by  
8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device  
offers access times to 100 ns with power dissipation of just 54 mW over the industrial  
temperature range. 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.  
To allow for simple in-system reprogrammability, the AT29LV020 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 AT29LV020 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 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.
