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.
