29C256 SMD PLCC 256k 120ns CMOS Flash Memory in Pakistan

The 29C256 is a five-volt-only in-system Flash programmable and erasable read-only memory (PEROM). Its 256K of memory is organized as 32,768 words by 8 bits. The device offers access times to 70 ns with a power dissipation of just 275 mW. When the device is deselected, the CMOS standby current is less than 300 µA. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from a static RAM. Reprogramming the AT29C256 is performed on a page basis; 64 bytes of data are loaded into the device and then simultaneously programmed.
