It features 256KB single-cycle flash memory, 96KB low-latency SRAM and rich communication peripherals. This MCU integrates a complete 10/100 Ethernet MAC and on-chip PHY, USB 2.0 Full-Speed Host/Device/OTG controller, and dual CAN 2.0B interfaces. Suitable for industrial and commercial environments, The is widely applied in industrial automation systems, smart grids, network gateways and embedded test equipment.
Core Advantages
80MHz ARM Cortex-M3 Core Execution
Equipped with a high-speed 32-bit RISC core, nested vector interrupt controller (NVIC) and single-cycle multiplier, it delivers high instruction efficiency and ensures stable operation for real-time control loops.
On-Chip 10/100 Ethernet MAC & Physical Layer (PHY)
Integrated 10/100 Mbps Ethernet MAC and PHY eliminates the need for external transceiver chips, effectively reducing PCB layout complexity and overall BOM cost.
Advanced Simultaneous Multi-Bus Communications
Integrates dual CAN controllers, USB 2.0 Full-Speed OTG, and up to three independent UARTs, enabling stable data interaction between local networks and traditional industrial equipment.
Substantial Internal Volatile & Non-Volatile Memory
Built-in 256KB program flash and 96KB SRAM provide sufficient resources to run real-time operating systems (RTOS), network protocol stacks and large data buffers.
