NEC µPD10/100 Series
Integrated Circuits

This series is a member of the JMOS family. See the general notes about the JMOS family for more details.
Known Devices: µPD10, µPD10C, µPD11, µPD13, µPD13C, µPD14, µPD15C,
µPD101C, µPD102C, µPD106, µPD110C, µPD116C.
Source of Data: - Series data and pinouts for the µPD10, µPD13, µPD14 were derived from a manufacturer schematic and reverse engineering of a Toshiba Model BC-1212 (1996 Jul).
- µPD116C: Pinout was derived from reverse engineering of a Casio 121B by Mick Metselaar (2006 Dec).
- Others: Data was derived from reverse engineering of a Commodore DAC-612 (2000 Feb).
Packaging: TO-100 (10-pin) and TO-101 (12-pin) cans and standard DIP. Devices in a DIP package have a suffix of "C" appended to the part number. In some cases the same device was produced in both can and DIP packages, the "C" distinguishing them.
Related Series: NEC µPD1, Toshiba TM4000, Hitachi HD3100, Hitachi HD700
Notes:
 
  • The µPD110C is inferred to be 4 MOS transistors as shown below. In logic terms, each element appears as a bidirectional switch with an inverted control input. The switch is closed when the control input is FALSE (-24V). They can be used several ways: inverters, XOR gates, AND gates with inverted inputs, etc.

    Due to their bidirectionality, care is taken in use to ensure other 'wire-ORed' outputs do not feed back through the element to affect the state of the signal on the non-inverted input.

 
  • IC packages as viewed from above.
