AT29C512-90JU

Flash Mem Parallel 5V 512Kbit 64K x 8 90ns 32Pin PLCC

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 temperature 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.
