- A low pin count (LPC) interface for host communication and LPC device access
How to Use the NPCE781LA0DX IC?
The NPCE781LA0DX IC can be used for various applications that require an embedded controller with LPC interface and advanced features. Some of the possible applications include:
- Notebook computers
- Desktop computers
- Industrial PCs
- Embedded systems
- Smart devices
To use the NPCE781LA0DX IC, you need to follow these steps:
- Download the Nuvoton Npce781la0dx Datasheet 11.pdf from the Nuvoton website or other sources. This document contains all the information you need to understand the features, functions, specifications, and pin assignments of the IC.
- Design your system according to your application requirements and the specifications of the NPCE781LA0DX IC. You need to consider the power supply, clock source, reset circuit, LPC bus, SPI flash, GPIOs, ADCs, PWMs, UARTs, SIRQs, SMBus, ECI, PS/2, CIR, and other interfaces of the IC. You also need to select the appropriate external components, such as resistors, capacitors, crystals, flash memory, keyboard, mouse, fan, battery, etc.
- Program the NPCE781LA0DX IC using the SPI flash interface. You need to write your own firmware code or use the existing code provided by Nuvoton or other sources. You can use any SPI flash programmer that supports the NPCE781LA0DX IC. You need to follow the programming procedure and commands described in the datasheet.
- Test and debug your system using the ECI interface. You can use any ECI debugger that supports the NPCE781LA0DX IC. You can monitor and control the status and parameters of the IC using the ECI commands described in the datasheet.
How to Use the CIR Interface?
The CIR interface is a feature of the NPCE781LA0DX IC that allows it to receive infrared signals from a remote control. The CIR interface can support various consumer infrared (CIR) standards, such as RC-6, XBox*, and Generic CIR. The CIR interface can be used for applications that require remote control inputs, such as media players, smart TVs, or home automation systems.
To use the CIR interface, you need to follow these steps:
- Connect an infrared receiver module to the CIR pin of the NPCE781LA0DX IC. The CIR pin is pin 128 of the 128-pin LQFP package. You also need to connect a pull-up resistor and a bypass capacitor between the CIR pin and the ground, as shown in the datasheet.
- Select the CIR standard that matches your remote control in the BIOS of your system. You can choose from RC-6, XBox*, or Generic CIR options. The BIOS settings may vary depending on your system manufacturer and model.
- Install the CIR driver for your operating system. For Windows 10*, you can download the CIR driver from the Intel website. For Linux*, you can use the drivers supplied by your Linux distribution or community.
- Test and use your remote control with your system. You can use any application that supports CIR inputs, such as Windows Media Center*, Kodi*, or LIRC*.
