3 / 102 page 3 µPD17145(A1), 17147(A1), 17149(A1) POC circuit Operating voltage Package One-time PROM version µPD17P149 Timer 3 channels • Internal interrupt: 4 FUNCTION LIST Part Number µPD17145 (A1) µPD17147 (A1) µPD17149 (A1) Item ROM capacity 2 KB (1024 × 16 bits) 4 KB (2048 × 16 bits) 8 KB (4096 × 16 bits) RAM capacity 110 × 4 bits Stack Address stack × 5, interrupt stack × 3 • I/O : 20 I/O ports 23 • Input : 2 • Sense input (INT pinNote): 1 A/D converter input 4 channels (shared with port pins), absolute accuracy: ±1.5 LSB MAX. • 8-bit timer/counter: 2 channels (can be used as 1 channel of 16-bit timer) • 7-bit basic interval timer: 1 channel (can be used as watchdog timer) Serial interface 1 channel (3-wire) • Multiple interrupt by hardware (3 levels MAX.) • External interrupt (INT): 1 Rising edge, falling edge, or both rising and falling edges selectable for detection. Interrupt • Timer 0 (TM0) • Timer 1 (TM1) • Basic interval timer (BTM) • Serial interface (SIO) Instruction execution time 2 µs (at 8 MHz, ceramic oscillation) Standby function HALT, STOP Mask option (Can be used in application circuit that operates on VDD = 5 V ± 10 %, 400 kHz to 4 MHz) 2.7 to 5.5 V (at 400 kHz to 2 MHz) 4.5 to 5.5 V (at 400 kHz to 8 MHz) 28-pin plastic shrink DIP (400 mil) 28-pin plastic SOP (375 mil) Quality grade is "standard" and not (A1). Operating temperature range: Ta = –40 to +85 ˚C Note The INT pin is used as an input pin (sense input) when the external interrupt function is not used. The status of this pin is read by using the INT flag of a control register, not by a port register. Caution The PROM version is functionally compatible with the mask ROM versions but its internal circuit and part of the electrical characteristics are different from those of the mask ROM versions. To replace the PROM version with a mask ROM version, thoroughly conduct application evaluation by using a sample of the mask ROM version. |
