29C512中文资料512K 64K x 8 5-volt Only CMOS Flash Memory数据手册Microchip规格书

描述 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.
