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. All the instructions consist of 16 bits per word. In addition, a one-time PROM version, the µ PD17P149, is also available for program evaluation. The functions of these microcontrollers are described in detail in the following User’s Manual. Be sure to read the following manual when designing your system: µ PD17145 Subseries User’s Manual: IEU-1383 FEATURES 17K architecture Program memory (ROM) : General-purpose register type : Instruction length fixed to 16 bits : µPD17145(A1) : 2 KB (1024 × 16 bits) : µPD17147(A1) : 4 KB (2048 × 16 bits) : µPD17149(A1) : 8 KB (4096 × 16 bits) Data memory (RAM) External interrupt Instruction execution time 8-bit A/D converter Timer Serial interface POC circuit (mask option) Operating voltage Operating temperature : VDD = 2.7 to 5.5 V (at 400 kHz to 2 MHz) : VDD = 4.5 to 5.5 V (at 400 kHz to 8 MHz) : Ta = –40 to +110 ˚C : 110 × 4 bits : 1 (INT pin, with sense input) : 2 µs (at 8 MHz: ceramic oscillation) : 4 channels, absolute ...
