UPD17149 SMALL/ GENERAL-PURPOSE 4-BIT SINGLE-CHIP MICROCONTROLLERS

DATA SHEET MOS INTEGRATED CIRCUIT µPD17145(A1), 17147(A1), 17149(A1) SMALL, GENERAL-PURPOSE 4-BIT SINGLE-CHIP MICROCONTROLLERS The µ PD17145(A1), 17147(A1), and 17149(A1) are 4-bit single-chip microcontrollers integrating an 8-bit A/D converter (4 channels), a timer function (3 channels), and a serial interface. These microcontrollers employ a CPU of the general-purpose register type that can execute direct memory operations and direct memory-to-memory data transfer for efficient programming..
