UPD17071GB-012-1A7中文资料瑞萨数据手册PDF规格书

DESCRIPTION

The µPD17071GB-012 is a CMOS microcontroller with an on-chip PLL frequency synthesizer for receiving international FM and AM and Japanese TV broadcasting.

In addition, because it includes a prescaler (230 MHz MAX.), IF counter, and LCD controller/driver, it constitutes a high-performance, multi-function FM, AM, or TV tuner on a single chip.

Housed in a 56-pin QFP and driven by two dry cells at a low voltage (VDD = 1.8 to 3.6 V), the µPD17071GB-012 is ideal for creating a compact portable clock radio and radio cassette recorder.
