DATA SHEET
MOS INTEGRATED CIRCUIT
µPD17145(A1), 17147(A1), 17149(A1)
SMALL, GENERAL-PURPOSE
4-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD17145(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 µPD17P149, 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:
µPD17145 Subseries User’s Manual: IEU-1383

4 channels (shared with port pins), absolute accuracy: ±1.5 LSB MAX.
3 channels
• 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)
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.
• Timer 0 (TM0)
• Internal interrupt: 4
• Timer 1 (TM1)
• Basic interval timer (BTM)
• Serial interface (SIO)
2 µs (at 8 MHz, ceramic oscillation)
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)
µPD17P149
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.
