... CMOS and TTL Compatible Inputs and Outputs Commercial and Industrial Temperature Ranges Description The AT29C512 is a 5-volt-only in-system Flash programmable and erasable read only memory (PEROM). Its 512K of memory is organized as 65,536 words by 8 bits. Manu- factured with Atmel’s advanced nonvolatile CMOS technology, the device offers ac- cess times with power dissipation of just 275 mW over the commercial tem- perature range ...

... Description (Continued) To allow for simple in-system reprogrammability, the AT29C512 does not require high input voltages for pro- gramming. 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 AT29C512 is performed on a sector basis; 128-bytes of data are loaded into the device and then simultaneously programmed ...
