... CMOS and TTL Compatible Inputs and Outputs Commercial and Industrial Temperature Ranges Description The AT29C010A is a 5-volt-only in-system Flash programmable and erasable read only memory (PEROM). Its 1 megabit of memory is organized as 131,072 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times with power dissipation of just 275 mW over the commer- cial temperature range ...

... Description (Continued) tion of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29C010A 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 internally latched, freeing the address ...

... These two 8K memory sections are referred to as boot blocks . Secure code which will bring up a system can be contained in a boot block. The AT29C010A blocks are lo- cated in the first 8K bytes of memory and the last 8K bytes of memory. The boot block programming lockout feature can therefore support systems that boot from the lower addresses of memory or the higher addresses ...
