HF88M02

The HF88M02 is a command interfaced 256K x 8 bit Mask ROM. HF88M02 features command mode interface with external CPU or MCU. In other words, it uses only 8-bit data bus and a few additional control pins to load addresses and provide the ROM access as well as expansion I/O ports capability. This design not only reduces pin count required to access data in ROM dramatically but also allows for systems expansion to higher capacity memories while using the existing board design. The application areas include voice, graphic, data storage in consumer product.
