   • Buzzer output capability
• Interrupt function with importance attached to applications
   • For power-off detection
   • For remote controlled reception
• Product with an on-chip PROM : µPD75P216A, µPD75P218 (on-chip EPROM : WQFN package)

The UPD75216A is a microcomputer with a CPU capable of 1-, 4-, and 8-bit data processing, ROM, RAM, I/O ports,a fluorescent display tube controller/driver, a watch timer, a timer/pulse generator capable of outputting 14-bit PWM,a serial interface and a vectored interrupt function integrated on a single-chip.

The UPD75216A is a product with the ROM capacity and the number of display segments extended for theµPD75208.

UPD75216A uses the VCR, ECR and CD fluorescent display tubes as display devices and is most suitable for applications requiring the timer/watch function and high-speed interrupt servicing.  It can help to provide the unit with many functions and to decrease performance costs.
