1. 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 to 70 ns with power dissipation of just 275 mW over the commer-

cial temperature range. When the device is deselected, the CMOS standby current is

less than 100 µA. The device endurance is such that any sector can typically be writ-

ten to in excess of 10,000 times.

To allow for simple in-system reprogrammability, the AT29C010A 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 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 and data bus for other operations. Following the initiation

of a program cycle, the device will automatically 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.
