Description
The AT49F512 is a 5-volt-only in-system programmable and erasable Flash Memory. Its 512K of memory is organized as 65,536 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 70 ns with a power dissipation of just 165 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA.
