2 / 13 page No. 7275-2/13 LC723461W, 723462W Continued from preceding page. • External reset input: During CPU and PLL operations, instruction execution is started from location 0. • Built-in power-on reset circuit: The CPU starts execution from location 0 when power is first applied. • Halt mode: The controller-operating clock is stopped. • Backup mode: The crystal oscillator is stopped. • Static power-on function: Backup state is cleared with the PF port • Beep tone: 1.5 and 3.1 kHz • Built-in DC-DC converter: For LCD and A/D converter use (3 V) Can also be used for TU + B creation by using a secondary coil. (The DC-DC converter voltage step-up operation can be stopped with the DCDCC instruction.) • Built-in remaining battery life verification function: Converts the VDD pin level through AD converter. • Memory retention voltage: 0.5 V or higher • Dedicated memory power supply: The RAM retention time has been increased by the provision of a dedicated memory power supply. • Package: SQFP-64 (0.5-mm pitch) • VDD power supply: 0.9 to 1.8 V Pin Assignment 15 16 13 14 11 12 9 10 7 8 5 6 3 4 1 2 61 62 63 64 58 59 60 54 55 56 51 52 53 49 50 57 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 30 31 17 18 19 20 21 22 23 24 25 26 27 28 29 S3 S4 S5 S6 S7 S8 S9 S10 S11 S12 S13/PH 0 S14/PH 1 S15/PH 2 S16/PH 3 S17/PG0 S18/PG1 XOUT LC723461W/3462W SQFP-64 PA3 PA2 PA1 PA0 PB3 PB2 PB1 PB0 PC3 PC2 PC1 PC0 PD3 PD2 IN T1/P D I/O I/O I/O I/O I/O I O O I I *: The VDD pin can also function as ADI2 A/D converter input. |
