7 / 108 page 7 T8xC5121 4164C–SCR–07/03 RST V CC I/O Reset input Holding this pin low for 64 oscillator periods while the oscillator is running resets the device. The Port pins are driven to their reset conditions when a voltage lower than V IL is applied, whether or not the oscillator is running. This pin has an internal pull-up resistor which allows the device to be reset by connecting a capacitor between this pin and VSS. Asserting RST when the chip is in Idle mode or Power-down mode returns the chip to normal operation. The output is active for at least 12 oscillator periods when an internal reset occurs. XTAL1 V CC I Input to the on-chip inverting oscillator amplifier To use the internal oscillator, a crystal/resonator circuit is connected to this pin. If an external oscillator is used, its output is connected to this pin. XTAL2 V CC O Output of the on-chip inverting oscillator amplifier To use the internal oscillator, a crystal/resonator circuit is connected to this pin. If an external oscillator is used, XTAL2 may be left unconnected. V CC PWR Supply voltage V CC is used to power the internal voltage regulators and internal I/O’s. LI PWR DC/DC input LI must be tied to V CC through an external coil (typically 4, 7 µH) and provide the current for the pump charge of the DC/DC converter. CVCC PWR Card Supply voltage CVCC is the programmable voltage output for the Card interface. It must be connected to an external decoupling capacitor. DVCC PWR Digital Supply voltage DVCC is used to supply the digital core and internal I/Os. It is internally connected to the output of a 3V regulator and must be connected to an external decoupling capacitor. EV CC V CC PWR Extra supply voltage EV CC is used to supply the level shifters of UART interface I/O pins. It must be connected to an external decoupling capacitor. This reference voltage is generated internally (automatically or not), or it can be connected to an external voltage reference. CVSS GND DC/DC ground CVSS is used to sink high shunt currents from the external coil. VSS GND Ground ONLY FOR PLCC52 version Table 1.
