1. 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. Man-

ufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers

access times to 70 ns with power dissipation of just 275 mW over the commercial tem-

perature 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 written to

in excess of 10,000 times.

To allow for simple in-system reprogrammability, the AT29C512 does not require high

input voltages for programming. Five-volt-only commands determine the operation 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.

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.
