LC7233

The LC7233 is designed as the single-chip electronic tuning microcontroller that supports control of an electronic tone / /volume control IC and handles detachable front panel products based on the LC75853E/W keyed LCD driver. It is designed for automotive use and incorporates a PLL-based receiver that can receiver all major worldwide radio transmissions.

Features of the LC7233 are:(1)supports detachable front panel products, system chips;(2)supports anti-theft LED flashing and reminder to remove panel alarm functions;(3)supports control of an electronic tone / volume control IC, functions: bass, treble, balance and fader;(4)muting function (with key, out and electronic tone controls);(5)supports two color illumination control (dual systems);(6)reduced LCD display output pin count achieved by operating at 1/3 duty and 1/3 bias drive using the LC75853E/W;(7)auto preset memory function;(8)radio monitor output: operates during tape FF/REW;(9)tape character display;(10)supports use of electronic power switch;(11)twenty diode matrix settings.

The absolute maximum ratings of the LC7233 can be summarized as:(1)maximum supply voltage: -0.3 to +6.5 V;(2)allowable power dissipation: 400 mW;(3)operating temperature: -40 to +85;(4)storage temperature: -45 to +125.
