AT29C1024-70JI集成電路（IC）的存儲器規(guī)格書PDF中文資料

Description

The AT29C1024 is a 5-volt-only in-system Flash programmable and erasable read only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 330 mW. When the device is deselected, the CMOS standby current is less than 200 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 AT29C1024 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 AT29C1024 is performed on a sector basis; 128 words of data are loaded into the device and then simultaneously programmed.
