The WWDT time-out interval is calculated as follows: Pre-scale Value * Counter Value / FWWDT Pre-scale Value: The pre-scale value counter Value: The maximum value of the counter, which is a constant 64 FWWDT: Clock source frequency of WWDT There are two kinds of WWDT clock sources for selection: HCL...

The Window Watchdog Timer (WWDT) protects the entire system by restarting the chip when the program is unable to control due to unexpected errors during the execution of the program and the WwDT counter is reset incorrectly. The WWDT has a 6-bit counter, and a settable Reload Window. During operatio...

The GPIO De-bounce function is used to filter noise or interference on the pin. After a voltage signal generates a rising or falling edge, if the time to keep high or low level exceeds the De-bounce time set by the user, a GPIO interrupt occurs. However, there is a limitation related to this functio...

The SWD or ICE interface contains five pins, including VDD, ICE_DAT, ICE_CLK, nReset and VSS. Through the SWD or ICE interface, the user can do MCU programming or debugging with the Nu-Link. Specifically, the nReset pin is used to reset the MCU or initialize SWD and ICE signals. If the Reset pin is ...

Standard 8051 series which can be divided into Part numbers with ISP function: Part numbers without ISP function: The user can write the ISP program through a third-party programming tool. Low Pin 8051 series which can be divided into Part numbers with ISP function: Part numbers without ISP function...

Please read storage conditions and related precautions on the chip vacuum packaging aluminum bag. For the location of the storage conditions and related precautions, please refer to the following figure.

Currently, the LCD driver function is supported by four Nuvoton MCU series: Nano110, Nano 130, Nano 112, and N76E616 series. Specifically, the first three series include the ARM/ Cortex? M0 core, and the last one includes the 8051 core. Related specifications are listed below: Note: Charge pump can ...

VDD12 in the NUC505 can be powered from an external LDO or internal LDO. External LDO: VDD12 in the NUC505 is connected to an external 1.2V, and LDO_CAP connects a 4.7uF capacitor to ground, as shown in Figure 1. Internal LDO: LDO_CAP in the NUC505 is first connected to the 4.7uF capacitor, and then...

The RTC function in the NUC505 needs to be enabled by RTC_WAKEUP. When the system is powered on, RTC_nRWAKE needs to be grounded so that the RTC function can be enabled. After power on, if the RTC_nRWAKE pin continues low for a period of time (set by the RTC_POWCTL register), the system hardware wil...

Use the ICP tool to enable the MTP encryption function. The related MTP setting is shown in Figure 1. After the MTP related setting, you can select MTP to encrypt the file. Then, refresh the data area and save the file to obtain an encrypted bin file, as shown in Figure 3. Then, select the Offline P...
