AT28C256-15PU Datasheet PDF – 256K paged CMOS EPROM

Part Number: AT28C256-15PU

Function: 256K(32K x 8) paged CMOS EPROM

Package: 28 Pin DIP, SIOC

Manufacturer: Atmel Corporation





The AT28C256-15PU is a high-performance electrically erasable and programmable read only memory. Its 256K of memory is organized as 32,768 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 150 ns with power dissipation of just 440 mW. When the device is deselected, the CMOS standby current is less than 200 µA.

The AT28C256 is accessed like a Static RAM for the read or write cycle without the need for external components. The device contains a 64-byte page register to allow writing of up to 64 bytes simultaneously. During a write cycle, the addresses and 1 to 64 bytes of data are internally latched, freeing the address and data bus for other operations. Following the initiation of a write cycle, the device will automatically write the latched data using an internal control timer.
