CHAPTER 1 GENERAL
The µPD17120, 17121, 17132 and 17133 are 4-bit single-chip microcontrollers employing the 17K architecture
and containing 8-bit timer (1 channel), 3-wire serial interface, and power-on/power-down reset circuit.
The µPD17P132 and 17P133 are the one-time PROM version of the µPD17132 and 17133, respectively, and are
suitable for program evaluation at system development and for small-scale production.
The following are features of the µPD17120 subseries.
• Comparator input (µPD17132, 17133, 17P132, 17P133 only)
. Comparison function with external reference voltage (Vref)
. Can be used as 4-bit A/D converter by using 15 types of internal reference voltage (1/16 to 15/16 VDD) depending
on the software
• 3-wire serial interface: 1 channel
• Power-on/power-down reset circuit (reducing external circuits)
µPD17P132 and 17P133 can operate in the same way as mask ROM version
. VDD = 2.7 to 5.5 V
These features of the µPD17120 subseries are suitable for use as a controller or a sub-microcomputer device in
the following application fields;
• Electric fan
• Hot plate
• Audio equipment
• Mouse
• Printer
• Plain paper copier
