The N9H series, developed by Nuvoton, is based on the ARM926EJ-S core. This series includes the N9H30F71IEC model with a CPU operating at up to 300 MHz. The series is distinguished for its use of a Multi Chip Package (MCP) with SDRAM stacked, size ranging from 2 MB to 128MB, thereby reducing PCB size and electromagnetic interference (EMI) to minimize system design efforts and shorten the product design cycle time.
Function & Applications
Conveniently complete with a Board Support Package (BSP) bearing the emWin embedded GUI library licensed from SEGGER, the N9H series enables developers to quickly and efficiently create high quality Human Machine Interfaces (HMI). This series has been designed ideally for LCD display applications such as the HMI of home automation and industrial automation. The N9H30F71IEC specifically supports industrial temperature from - 40 ℃ to 85 ℃ targeting Industrial Control and HMI.
For optimum performance, the N9H30F71IEC exhibits a maximum resolution of 1024 x 768 via its 24-bit TFT RGB interface. It also contains a 2D graphics accelerator, MJPG/H.264 video decoder, and resistive touch screen interface. Its hardware video codec is capable of H.264 720P performance at 25fps and supports MJPEG.
Package Types, Interfaces & Pin Configuration
The N9H30F71IEC offers 216-pin LQFP packages stacked with 128 MB DDR-II Memory to reduce PCB size and EMI issues. Interface support includes SPI, I2C, SDIO/ eMMC, NAND Flash, up to 11 sets of UART, and USB 2.0 Host/Device along with 24bit LCD controller interface, 2 sets CAN, and 2 sets 10/100Mbps Ethernet MAC. It's video input interface supports CCIR656/CCIR601 interface with a max resolution up to 3M pixels.
Reliability & Lifespan
One feature guaranteeing reliability is its operational temperature tolerance, exhibited by models N9H20 and N9H26 supporting operating temperatures from -20 ℃ to 85 ℃. The N9H30F71IEC model goes further, supporting an industrial standard temperature range of - 40 ℃ to 85 ℃.
