N9H30F51I

Microprocessors Overview

The N9H30F51I is a 32-bit microprocessor based on the ARM926EJ-S core, operating at up to 300 MHz. It integrates 16 KB I-cache and 16 KB D-cache within a 216-pin LQFP package stacked with 64 MB DDR-II memory. Key peripherals include an LCD controller supporting up to 1024x768 resolution, video input interfaces (CCIR656/601), dual SD host controllers, NAND Flash interface, 11 UARTs, two CAN channels, two Ethernet MACs, and High-Speed USB 2.0 Host/Device controllers.

Microprocessors Feature Summary

• Integrates ARM926EJ-S processor core with hardware cache for efficient execution
• Features stacked 64 MB DDR-II memory in package to reduce PCB size and EMI
• Includes dedicated 2D graphics accelerator and JPEG decoder for HMI applications
• Supports multiple boot sources including SPI Flash, NAND Flash, eMMC, and USB

Microprocessors Applications

• Industrial Human-Machine Interface (HMI) systems
• Industrial control panels requiring robust connectivity
• Smart home central control units with networking capabilities
• Interactive display terminals with video playback functions

Microprocessors Procurement Notes

Verify component status as the N9H30 series may be subject to end-of-life notices or obsolescence warnings from Nuvoton. Confirm availability through authorized distributors and check for recommended replacement parts such as the N9H30F61IEC if current stock is limited. Ensure design-in compatibility with existing firmware and hardware layouts before finalizing procurement plans.

Microprocessors Selection Notes

Select this model for designs requiring high-performance processing combined with integrated graphics acceleration and substantial onboard memory. The industrial temperature range (-40°C to 85°C) makes it suitable for harsh environments. Consider pinout compatibility and peripheral requirements like Ethernet and CAN when comparing against other N9H variants.

Microprocessors Part Context

This component belongs to the N9H series of 32-bit microprocessors designed primarily for Human-Machine Interface applications. The series leverages the ARM926EJ-S architecture to deliver multimedia capabilities, including video decoding and 2D graphics acceleration, while maintaining low power consumption and small form factor through package-stacked memory solutions.

Microprocessors Replacement Considerations

Publicly confirmed substitutes include the N9H30F61IEC and N9H30F63IEC, which share similar core specifications and peripheral sets. Verify package compatibility and thermal ratings when transitioning between these variants.
