CMOS IC

LC72311W, 72312W, 72313W

Low-Voltage ETR-Controller

Preliminary

Overview

•

A/D converter:

Four-input 8-bit converter

The LC72311W, LC72312W, and LC72313W are

low-voltage single-chip FM/AM electronic tuning

microcontrollers that include a built-in PLL circuit for

frequencies up to 230 MHz, a 1/4 duty 1/2 bias LCD

controller, and a small EEPROM. These microcontroller

also provide a low-power standby mode that reduces power

consumption by switching the system clock frequency.

Furthermore, since these devices include a low-pass filter

amplifier required for the electronic tuning system and a

tuning voltage generator circuit, they can contribute to

reduced end product costs through lower parts counts.

These ICs are optimal for use in low-voltage portable audio

equipment that includes a radio receiver.

•

Input ports:

9 or 10 ports (Ports PA, PF, and HCTR)

The PF port is shared with the A/D converter, and HCTR

is shared with the IF counter.

•

Output ports:

8 ports (Ports PB and PE)

PE3 is shared with the BEEP pin, PE0 to PE2 are

open-drain ports, and the PB port can be switched to

function as an open-drain port.
