1 / 14 page Ordering number : ENN6472 32700RM (OT) No. 6472-1/14 Overview The LC72348G/W and LC72349G/W are low-voltage electronic tuning microcontrollers that include a PLL that operates up to 230 MHz and a 1/4 duty 1/2 bias LCD driver on chip. These ICs can contribute to further end product cost reduction than the LC72341 series while providing improved standby current characteristics. Also these ICs can use the application program for the LC72341 series except the IF counter function. These ICs are optimal for use in low-voltage portable audio equipment that includes a radio receiver. Function • Program memory (ROM): — 3072 × 16 bits (6K bytes) LC72348G/W — 4096 × 16 bits (8K bytes) LC72349 G/W • Data memory (RAM): — 192 × 4 bits LC72348 G/W — 256 × 4 bits LC72349 G/W • Cycle time: 40 µs (all 1-word instructions) at 75kHz crystal oscillation • Stack: 8 levels • LCD driver: 48 to 80 segments (1/4 duty, 1/2 bias drive) • Interrupts: One external interrupt Timer interrupts (1, 5, 10, and 50 ms) • A/D converter: Three input channels (5-bit successive approximation conversion) • Input ports: 7 ports (of which three can be switched for use as A/D converter inputs) • Output ports: 6 ports (of which 1 can be switched for use as the beep tone output and 2 are open- drain ports) • I/O ports: 16 ports (of which 8 can be switched for use as LCD ports and as mask options) Continued on next page.
