The µPD17010 is a 4-bit single-chip CMOS microcontroller containing hardware for digital tuning systems. The CPU uses a 17K architecture and can directly manipulate the data memory and control various operations and peripheral hardware with a single instruction. All instructions are 16-bit 1-word instructions.
