HF88M04

The HF88M04 is a command interfaced 512K x 8 bit Mask ROM. HF88M04 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.
