CMOS IC

LC723481W,723482W,723483W

Low-Voltage ETR-Controller

Overview

The LC723481W, 723482W, and 723483W are low-

voltage electronic tuning radio microcontrollers that

include a PLL that operates up to 250 MHz and a 1/4 duty

1/2 bias LCD driver on chip. These ICs include an on-chip

DC-DC converter, making it is easy to create the supply

voltages required for tuning and allowing cost reductions

in end products.

These ICs are optimal for use in low-voltage portable

audio equipment that includes a radio receiver.

I/O ports: 16 pins (Of these 8 can be switched over to

function as LCD ports as a mask options.)

PLL: Dead band control is supported. (Four types)

Reference frequencies: 1, 3, 3.125, 5, 6.25, 12.5,

and 25 kHz

Input frequencies: FM band: 10 to 250 MHz

AM band: 0.5 to 40 MHz

Input sensitivity:

FM band: 35 mVrms (50 mVrms at 130 MHz or higher

frequency)

AM band: 35 mVrms

IF counting: Using the HCTR input pin for 0.4 to

12 MHz signals

External reset input: During CPU and PLL operations,

instruction execution is started from

location 0.

Built-in power-on reset circuit:

The CPU starts execution from location 0 when power is

first applied.

Halt mode: The controller-operating clock is stopped.

Backup mode: The crystal oscillator is stopped.

Static power-on function: Backup state is cleared with

the PF port

• Beep tone: 1.5625 and 3.125 kHz

• Built-in low-pass filter amplifier: This circuit obviates

the need for an external amplifier for the PLL circuit and

contributes to reduced end product costs.

• Built-in DC/DC converter:

Cost reduced in tuner-use power supply circuit

• Memory retention voltage: 0.9 V at least

• V

voltage

— PLL: 1.8 to 3.6 V

— CPU: 1.4 to 3.6 V

— ADC: 1.6 to 3.6 V

• Optional function switches:

— PH0 to PH3/S13 to S16

— PG0 to PG3/S17 to S20

— PG0 to PG3 (open-drain output/general-purpose

output)

— PH0 to PH3 (open-drain output/general-purpose

output)

— FM DC/DC clock (75 kHz or 1/256 times the local

FM oscillator frequency)

— AM DC/DC clock (1/2, 1/4, 1/8, or 1/16 times the

AM local oscillator frequency)
