D32PRO

The D32PRO is a royalty-free, silicon proven, high performance soft core of a single-chip 32-bit embedded controller, with Floating Point Coprocessor.

The D32PRO is a royalty-free, silicon-proven high-performance 32-bit embedded controller soft core, featuring an integrated Floating Point Coprocessor. Designed for low-power, connected devices, the D32PRO delivers excellent code density, energy efficiency, and computational performance, making it a strong alternative to ARM Cortex M0/M0+/M1/M3 cores in deeply embedded and IoT applications.

With its optimized instruction set, the D32PRO reduces system instruction memory requirements while maintaining high performance. It is particularly suited for always-on, always-listening devices, low-frequency systems such as Bluetooth Low Energy (BLE) applications, and embedded platforms requiring dual- or multi-core scalability.

The D32PRO IP Core is fully customizable, allowing implementation in exact configurations to meet your project-specific requirements. It comes ready with a wide array of peripherals, including:

• USB

• SPI

• LCD

• HDLC

• UART

• Ethernet MAC

• CAN

• LIN

• RTC

This rich peripheral support enables rapid SoC integration with the CPU for advanced embedded designs.

Delivered with a fully automated test bench and a complete set of tests, the D32PRO ensures straightforward validation and seamless SoC integration at every stage of the design process.

Key Features:

• 32-bit embedded controller with integrated Floating Point Coprocessor

• Silicon-proven and royalty-free

• Optimized for low-power, always-on connected devices

• High code density reduces system instruction memory requirements

• Supports dual- and multi-core architectures

• Ready-to-use peripherals for rapid SoC integration (USB, SPI, UART, CAN, Ethernet, LCD, HDLC, LIN, RTC)

• Fully automated test bench for validation

• Ideal replacement for ARM Cortex M0/M0+/M1/M3 in IoT and embedded applications

D32PRO vs ARM Cortex-M Selection Guide

Why Choose D32PRO over ARM Cortex-M?

1. Floating Point Performance: Integrated FPU allows faster calculations in signal processing, sensor fusion, and IoT applications.

2. Ultra-Low Power: Optimized for always-on operation, saving battery life in connected devices.

3. High Code Density: Reduces on-chip memory requirements, lowering system cost.

4. Fully Customizable: Tailor peripherals, memory, and interfaces to your exact SoC needs.

5. Multi-Core Support: Unlike Cortex-M, D32PRO can scale to dual- or multi-core configurations for higher performance embedded systems.

6. Rich Peripheral Set: Pre-integrated, ready-to-use peripherals accelerate development and reduce integration time.

7. Royalty-Free Licensing: Eliminates recurring licensing costs, unlike proprietary ARM cores.
