AT29C010A

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 industrial

temperature range. 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.

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.
