LC72341G/W

Low-Voltage Single-Chip Microcontrollers with On-Chip PLL and LCD Driver Circuits

SANYO -> Panasonic 

Ordering number : EN*5799

Preliminary

CMOS IC

LC72341G/W, LC72342G/W, LC72343G/W

Low-Voltage Single-Chip Microcontrollers with On-

Chip PLL and LCD Driver Circuits

Overview

The LC72341G/W, LC72342G/W, and LC72343G/W are

single-chip microcontrollers with both a 1/4-duty 1/2-bias

LCD driver circuit and a PLL circuit that can operate at up

to 250 MHz integrated on the same chip. These ICs are

ideal for use in portable audio equipment.

Reference frequencies of 1, 3, 5, 6.25, 12.5, and

25 kHz can be provided.

• Input frequency range

— FM band: 10 to 130 MHz

130 to 250 MHz

— AM band: 0.5 to 15 MHz

Functions

• High-speed programmable divider

• Program memory (ROM)

— LC72341G/W: 2048 words × 16 bits (4KB)

— LC72342G/W: 3072 words × 16 bits (6KB)

— LC72343G/W: 4096 words × 16 bits (8KB)

• Data memory (RAM)

— LC72341G/W: 128 words × 4 bits

— LC72342G/W: 192 words × 4 bits

— LC72343G/W: 256 words × 4 bits

• Instruction cycle time

— 40 µs (for all single-word instructions.)

• Stack

— 4 levels (LC72341G/W)

— 8 levels (LC72342G/W, and LC72343G/W)

• LCD driver

— 48 to 80 segments (1/4-duty 1/2-bias drive)

• Timer interrupts

— One timer circuit providing intervals of 1, 5, 10, and

50 ms.

• External interrupts

— One external interrupt (INT)

• A/D converter

— Two channels (5-bit successive approximation)

• Input ports

— 7 (Of which two can be switched to function as A/D

converter inputs)

• Output ports

— 6 (Of which one can be switched to function as the

BEEP tone output. Two ports are open-drain ports.)

• I/O

ports

— 16 (Of which 8 can be selected to function as LCD

ports as mask options.)

• PLL circuit

— Two types of dead band control are supported, and an

unlock detection circuit is included.
