1 / 12 page 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 Package Dimensions unit: mm 3159-QFP64G unit: mm 3159-SQFP64 CMOS IC 31398RM (OT) No. 5799-1/12 Preliminary SANYO: QFP64G [LC72341G, 72342G, 72343G] SANYO: SQFP64 [LC72341W, 72342W, 72343W] SANYO Electric Co.,Ltd.
