UPD17P709

DATA SHEET MOS INTEGRATED CIRCUIT µPD17P709 4-BIT SINGLE-CHIP MICROCONTROLLER WITH BUILT-IN HARDWARE DEDICATED TO DIGITAL TUNING SYSTEMS The µPD17P709 is produced by replacing the built-in masked ROM of the µPD17704Note, µPD17705Note, µPD17707, µPD17708, and µPD17709 with a one-time PROM. The µPD17P709 allows programs to be written once, so that the µPD17P709 is suitable for preproduction in µPD17704, µPD17705, µPD17707, µPD17708, or µPD17709 system development or low-volume production. When reading this document, also refer to the publications on the µPD17704, µPD17705, µPD17707, µPD17708, or µPD17709. Note Under development The electrical characteristics (including power supply currents) and PLL analog characteristics of the µPD17P709 differ from those of the µPD17704, µPD17705, µPD17707, µPD17708, and µPD17709. In high-volume application set production, carefully check those differences. FEATURES Compatible with the µPD17704, µPD17705, µPD17707, µPD17708, and µPD17709 Built-in one-time PROM Supply voltage : 32K bytes (16384 × 16 bits) : VDD = 5 V ±10% ORDERING INFORMATION Part number Package 80-pin plastic QFP (14 × 14 mm, 0.65-mm pitch) µPD17P709GC-3B9 The information in this document is subject to change without notice.
