LC7233N-8818

Single-Chip PLL and Controller with

LCD Driver

Overview

The LC7233N-8818 is a single-chip electronic tuning

microcontroller that supports control of an electronic

tone/volume control IC (the LC7538JMD) 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 receive all major worldwide radio transmissions.

Features

• Supports detachable front panel products. System chips:

LC7233N, LC75853E/W and LC7538JMD

• Supports anti-theft LED flashing and reminder to

remove panel alarm functions.

• Supports control of an electronic tone/volume control IC

(the LC7538JMD). Functions: bass, treble, balance,

fader

• Muting function (with key, out and electronic tone

controls)

• Supports two color illumination control (dual systems).

• Reduced LCD display output pin count achieved by

operating at 1/3 duty and 1/3 bias drive using the

LC75853E/W.

• Up to 36 stations can be stored in preset memory: 6

stations for each band (FM1, FM2, FM3, VF, MW

(MW1) and LW (MW2)). Previous station function also

supported.

• Auto preset memory function

• Radio monitor output: operates during tape FF/REW.

• CD function (with key, in, and out)

• Tape function (Flashing direction display supported

when FF and REW signal inputs are provided.)

• Rich selection of double function keys for use with tape

players

• Tape character display

• Supports use of electronic power switch.

• Twenty diode matrix settings

• Supports radio reception throughout the world.

• Supports AM stereo reception in the USA and Japan.
