Description  
The AT29C256 is a five-volt-only in-system Flash programmable and erasable read  
only memory (PEROM). Its 256K of memory is organized as 32,768 words by 8 bits.  
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers  
access times to 70 ns with power dissipation of just 275 mW. When the device is  
deselected, the CMOS standby current is less than 300 µA. The device endurance is  
such that any sector can typically be written to in excess of 10,000 times.
