48 / 97 page NuMicro NUC230/240 Datasheet Dec. 30, 2014 Page 48 of 97 Revision 1.01 6.2.3 System Power Distribution In this chip, the power distribution is divided into three segments. Analog power from AVDD and AVSS provides the power for analog components operation. Digital power from VDD and VSS supplies the power to the internal regulator which provides a fixed 1.8 V power for digital operation and I/O pins. USB transceiver power from VBUS offers the power for operating the USB transceiver. Battery power from VBAT supplies the RTC and external 32.768 kHz crystal. The outputs of internal voltage regulators, LDO and VDD33, require an external capacitor which should be located close to the corresponding pin. Analog power (AVDD) should be the same voltage level with the digital power (VDD). 錯誤! 找不到參照來源。Figure 6-2 shows the NuMicro NUC230 power distribution, and Figure 6-3 shows the NuMicro NUC240 power distribution. 12-bit SAR-ADC Brown- out Detector Low Voltage Reset Analog Comparator Temperature Seneor FLASH Digital Logic Internal 22.1184 MHz & 10 kHz Oscillator AVDD AVSS LDO_CAP 1uF GPIO NUC230 Power Distribution LDO PLL POR50 POR18 External 32.768 kHz Crystal IO cell RTC ULDO 1.8V 1.8V Figure 6-2 NuMicro NUC230 Power Distribution Diagram |
