Description  
The AT29C1024 is a 5-volt-only in-system Flash programmable and erasable read  
only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16  
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device  
offers access times to 70 ns with power dissipation of just 330 mW. When the device  
is deselected, the CMOS standby current is less than 200 µA. The device endurance  
is such that any sector can typically be written to in excess of 10,000 times.
