NEC PD17072 17073 handbook

µPD17072 and 17073 are low-voltage 4-bit single-chip CMOS microcontrollers containing hardware ideal for organizing a digital tuning system. The CPU employs 17K architecture and can manipulate the data memory directly, perform arithmetic operations, and control peripheral hardware with a single instruction. All the instructions are 16-bit one-word instructions. As peripheral hardware, a prescaler that can operate at up to 230 MHz for a digital tuning system, a PLL frequency synthesizer, and an intermediate frequency (IF) counter are integrated in addition to I/O ports, an LCD controller/driver, A/D converter, and BEEP. Therefore, a high-performance, multi-function digital tuning system can be configured with a single chip of µPD17072 or 17073. Because the µPD17072 and 17073 can operate at low voltage (VDD = 1.8 to 3.6 V), they are ideal for controlling battery-cell driven portable devices such as portable radio equipment, headphone stereos, or radio cassette recorders.
