66 / 1348 page  Chapter 1 Device Overview MC9S12XD-Family MC9S12XDP512 Data Sheet, Rev. 2.21 66 Freescale Semiconductor 1.2.4.2 VDDR1, VDDR2, VSSR1, VSSR2 — Power and Ground Pins for I/O Drivers and for Internal Voltage Regulator External power and ground for I/O drivers and input to the internal voltage regulator. Because fast signal transitions place high, short-duration current demands on the power supply, use bypass capacitors with high-frequency characteristics and place them as close to the MCU as possible. Bypass requirements depend on how heavily the MCU pins are loaded. 1.2.4.3 VDD1, VDD2, VSS1, VSS2 — Core Power Pins Power is supplied to the MCU through VDD and VSS. Because fast signal transitions place high, short-duration current demands on the power supply, use bypass capacitors with high-frequency characteristics and place them as close to the MCU as possible. This 2.5-V supply is derived from the internal voltage regulator. There is no static load on those pins allowed. The internal voltage regulator is turned off, if VREGEN is tied to ground. NOTE No load allowed except for bypass capacitors. 1.2.4.4 VDDA, VSSA — Power Supply Pins for ATD and VREG VDDA,VSSA are the power supply and ground input pins for the voltage regulator and the analog-to-digital converters. 1.2.4.5 VRH, VRL — ATD Reference Voltage Input Pins VRH and VRL are the reference voltage input pins for the analog-to-digital converter. 1.2.4.6 VDDPLL, VSSPLL — Power Supply Pins for PLL Provides operating voltage and ground for the oscillator and the phased-locked loop. This allows the supply voltage to the oscillator and PLL to be bypassed independently. This 2.5-V voltage is generated by the internal voltage regulator. NOTE No load allowed except for bypass capacitors. |
