The following sections provide signal descriptions and related information about the functionality and configuration of the SPC560P34/SPC560P40 devices.

The internal voltage regulator requires an external NPN ballast, approved ballast list availbale in Table 15 , to be connected as shown in Figure 10 . Capacitances should be placed on the board as near as possible to the associated pins. Care should also be taken to limit the serial inductance of the V DD_HV_REG , BCTRL and V DD_LV_CORx pins to less than L Reg . (refer to Table 16 ).

Note:

The voltage regulator output cannot be used to drive external circuits. Output pins are to be used only for decoupling capacitance.

VDD_LV_COR must be generated using internal regulator and external NPN transistor. It is not possible to provide V DD_LV_COR through external regulator.

For the SPC560P34/SPC560P40 microcontroller, capacitor(s), with total values not below CDEC1 , should be placed between V DD_LV_CORx /V SS_LV_CORx close to external ballast transistor emitter. 4 capacitors, with total values not below C DEC2 , should be placed close to microcontroller pins between each V DD_LV_CORx /V SS_LV_CORx supply pairs and the VDD_LV_REGCOR /V SS_LV_REGCOR pair . Additionally, capacitor(s) with total values not below CDEC3 , should be placed between the V DD_HV_REG /V SS_HV_REG pins close to ballast collector. Capacitors values have to take into account capacitor accuracy, aging and variation versus temperature.

All reported information are valid for voltage and temperature ranges described in recommended operating condition, Table 10 and Table 11 .

1. Functional operating conditions are given in the DC electrical characteristics. Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the listed maxima may affect device reliability or cause permanent damage to the device.
2. Absolute maximum voltages are currently maximum burn-in voltages.
3. The difference between each couple of voltage supplies must be less than 300 mV, VDD_HV_IOy - V DD_HV_IOx < 300 mV.
4. Guaranteed by device validation.
5. Minimum value of TV DD must be guaranteed until V DD_HV_REG reaches 2.6 V (maximum value of V PORH )
6. Only when V DD_HV_IOx < 5.2 V

1. The difference between each couple of voltage supplies must be less than 100 mV, VDD_HV_IOy -VDD_HV_IOx < 100 mV.
2. To be connected to emitter of external NPN. Low voltage supplies are not under user control-they are produced by an onchip voltage regulator-but for the device to function properly the low voltage grounds (V SS_LV_xxx ) must be shorted to high voltage grounds (V SS_HV_xxx ) and the low voltage supply pins (V DD_LV_xxx ) must be connected to the external ballast emitter.
4. The low voltage supplies (V DD_LV_xxx ) are not all independent. - V DD_LV_COR1 and V DD_LV_COR2 are shorted internally via double bonding connections with lines that provide the low voltage supply to the data flash memory module. Similarly, V SS_LV_COR1 and V SS_LV_COR2 are internally shorted. - V DD_LV_REGCOR and V DD_LV_RECORx are physically shorted internally, as are V SS_LV_REGCOR and V SS_LV_CORx .
