N9H20K31N

Introduction

The N9H20K31N is a product in the N9H Human Machine Interface (HMI) Series developed by the company Nuvoton. It is based on the ARM926EJ-S core and CPUs operating at up to 200 MHz. The inclusion of Multi Chip Package (MCP) with SDRAM stacked, size ranging from 2 MB to 128MB, substantially minimizes PCB size and electromagnetic interference (EMI) - thereby reducing system design efforts and shortening product design cycle time. The N9H20K31N operates at up to 200 MHz and uses 8 MB SDRAM memory.

Function & Applications

The N9H series is designed to provide a high-quality Human Machine Interface (HMI). It delivers a built-in 24-bit TFT RGB interface with resolution support up to 1024x768, 2D graphics accelerator, MJPEG/ H.264 video decoder and resistive touch screen interface for LCD-based display applications. With a strong focus on LCD display applications, it is ideal for use as the HMI of home automation and industrial automation systems.

Performance Parameters

Key performance parameters of the N9H20K31N include operating power of up to 200 MHz, 8 KB I-cache/ 8 KB D-cache, and support for Boot from SPI Flash, NAND Flash or USB Device. It offers 128-pin packages stacked with 8 MB SDRAM Memory. The product also includes a video input interface that supports CCIR656/ CCIR601 interface with a maximum resolution up to 2M pixels.

Package Types, Interface & Pin Configuration

The N9H20K31N is provided in LQFP128 package types. It features built-in multiple interfaces including SPI, I²C, PWM, SDIO/eMMC, 2 sets of UART, NAND Flash interface, and 24bit LCD controller. Furthermore, it includes a full-speed USB 2.0 host and high-speed USB 2.0 device controller for added flexibility in design applications.

Reliability & Lifespan

The N9H20K31N is designed with high reliability supporting temperatures from -20 °C to 85 °C. It should be noted that the N9H30 component of the N9H series goes a step further by supporting industrial standard temperature from - 40 °C to 85 °C.

Standards & Certifications

Specific standards and certifications related to the N9H20K31N product are not provided in the available details. However, as a part of the N9H series, it's assumed to follows the standard manufacturing quality and safety protocols.

Application Cases & Reference Designs

The N9H20K31N is ideal for home control and HMI applications due to its design and performance features. The use of Nuvoton's licensed emWin embedded GUI library facilitates the quick and efficient creation of smooth, professional-quality HMI on this series. Examples of application cases or reference designs haven't been provided within the available content. The ease of use, along with flexible design options, certainly make the N9H20K31N a strong candidate for different design configurations in the automation industry.
