UPD17072 Product details

Description

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 i
