Nuvoton N9H20/N9H26 32-bit Microprocessors

Nuvoton N9H20/N9H26 32-bit Microprocessors are built on an Arm® ARM926EJ-S CPU and integrated with USB2.0 HS host/device. These microprocessors' open-source code environment provides product development with more flexibility. The N9H20/N9H26 32-bit microprocessors provide a Multi-Chip Package (MCP) to ensure high performance and to minimize the system design efforts. These microprocessors operate at input/output 3.3V voltage and -40°C to 125°C storage temperature range. The N9H20/N9H26 32-bit microprocessors are ideal for Human Machine Interface (HMI), home appliances, and advertisement.
