2 / 13 page (Continued from preceding page.) • PLL: Supports dead band control (two types) Reference frequencies: 1, 3, 5, 6.25, 12.5, and 25 kHz • Input frequencies: FM band: 10 to 230 MHz AM band: 0.5 to 10 MHz • Input sensitivity: FM band: 35 mV rms (50 mV rms at 130 MHz or higher frequency) AM band: 35 mV rms • External reset input: During CPU and PLL operation, instruction execution is started from location 0. • Built-in power-on reset circuit: The CPU starts executing from location 0 when power is first applied. • Static power-on function: Backup state clear function using the BATT pin. • Halt mode: The controller operating clock is stopped. • Backup mode: The crystal oscillator is stopped. • Beep tone: 1.5 and 3.1 kHz • Built-in DC-DC converter: Two systems (One system can be used as an external circuit power supply by providing an external transistor.) • Built-in low-pass filter amplifier: An external low-pass filter amplifier circuit is no longer required in end products. • Remaining power check function: The battery voltage can be directly converted to a digital value by the A/D converter. • Memory retention voltage: 0.9 V or higher. •VDD voltage: 0.9 to 1.8 V • Package: SQFP-64 (0.5 mm lead pitch) No. 6171-2/13 LC72344W, 72345W LC72344W LC72345W XOUT TEST2 PA3 PA2 PA1 PA0 PB3 PB2 PB1 PB0 PC3 PD3 PC2 PC1 PC0 PD2 S2 S5 S7 S9 S12/PH0 S11 S8 S6 S4 S3 S10 S13/PH1 S15/PH3 S14/PH2 S17/PG1 (Top view) S16/PG0 1 2 3 4 5 6 7 8 11 9 10 14 15 12 16 13 48 47 45 46 43 44 41 39 40 42 36 37 38 35 33 34 Pin Assignment |
