Its 1 megabit of memory is organized as 131,072 words by 8bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the deviceoffers access times to 70 ns with power dissipation of just 275 mW over the commercialtemperature range. When the device is deselected, the CMOS standby current isless than 100 µA. The device endurance is such that any sector can typically be writtento in excess of 10,000 times.To allow for simple in-system reprogrammability, the AT29C010A does not requirehigh input voltages for programming.
