13 / 82 page ![]() SPC560D30x, SPC560D40x Package pinouts and signal descriptions Doc ID 16315 Rev 5 13/82 3.4 Pad types In the device the following types of pads are available for system pins and functional port pins: S = Slow(a) M = Medium(a) (b) F = Fast(a) (b) I = Input only with analog feature(a) J = Input/Output (‘S’ pad) with analog feature X = Oscillator 3.5 System pins The system pins are listed in Table 5. Table 4. Voltage supply pin descriptions Port pin Function Pin number LQFP64 LQFP100 VDD_HV Digital supply voltage 7, 28, 34, 56 15, 37, 52, 70, 84 VSS_HV Digital ground 6, 8, 26, 33, 55 14, 16, 35, 51, 69, 83 VDD_LV 1.2V decoupling pins. Decoupling capacitor must be connected between these pins and the nearest VSS_LV pin.(1) 11, 23, 57 19, 32, 85 VSS_LV 1.2V decoupling pins. Decoupling capacitor must be connected between these pins and the nearest VDD_LV pin.(1) 10, 24, 58 18, 33, 86 VDD_BV Internal regulator supply voltage 12 20 1. A decoupling capacitor must be placed between each of the three VDD_LV/VSS_LV supply pairs to ensure stable voltage (see the recommended operating conditions in the device datasheet for details). a. See the I/O pad electrical characteristics in the device datasheet for details. b. All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium (see the PCR[SRC] description in the device reference manual). |
