DATA SHEET MOS INTEGRATED CIRCUIT µPD784224, 784225, 784224Y, 784225Y www.datasheet4u.com 16/8-BIT SINGLE-CHIP MICROCONTROLLERS The µPD784224 and 784225 are products of the µPD784225 Subseries in the 78K/IV Series. Besides a highspeed and high performance CPU, these controllers have ROM, RAM, I/O ports, 8-bit resolution A/D and D/A converters, timers, serial interfaces, a real-time output port, interrupt functions, and various other peripheral hardware. The µPD784224Y and 784225Y are based on the µPD784225 Subseries with the addition of a multimastersupporting I2C bus interface. Flash memory versions, the µPD78F4225 and 78F4225Y, which replace the internal ROM of the mask ROM version with flash memory, and various development tools are also available. The functions are explained in detail in the following user’s manuals.
