Description
The AT49F010/HF010 are 5-volt only in-system programmable and erasable Flash
Memories. Their 1 megabit of memory is organized as 131,072 words by 8 bits. Man-
ufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer
access times to 45 ns (HF version) 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
A.
