LC72341W规格书详情
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.
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.
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
