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.

Note: 2. The VSENSE voltage
When the VDD voltage falls, the VSENSE flag is set at the point that voltage falls under 1.75 V (typical). The TST instruction can be used to read the
value of the VSENSE flag. Applications can easily determine when the batteries are exhausted by monitoring this flag. After VSENSE is set when the
supply voltage falls, it will not be reset if the supply voltage rises by less than 0.1 V, because the voltages detected by the VSENSE circuit differ when
the supply voltage is falling and when the supply voltage is rising.
