DATA SHEET
MOS INTEGRATED CIRCUIT
µPD17P719
4-BIT SINGLE-CHIP MICROCONTROLLER WITH
BUILT-IN HARDWARE DEDICATED TO DIGITAL TUNING SYSTEMS
The µPD17P719 is produced by replacing the built-in masked ROM of the µPD17717, µPD17718, and µPD17719
with a one-time PROM.
The µPD17P719 allows programs to be written once, so that the µPD17P719 is suitable for preproduction in
µPD17717, µPD17718, or µPD17719 system development or low-volume production.
When reading this document, also refer to the publications on the µPD17717, µPD17718, or µPD17719.
The electrical characteristics (including power supply currents) and PLL analog characteristics of
the µPD17P719 differ from those of the µPD17717, µPD17718, and µPD17719. In high-volume application
set production, carefully check those differences.
FEATURES
