With a maximum clock speed of 120 MHz, 512 KB Flash, and 64 KB SRAM, it integrates rich peripherals and communication interfaces. Designed for real-time performance, low power consumption, and industrial-grade reliability, it is ideal for applications such as industrial automation, smart home systems, medical devices, and network communication equipment.

Key Features

High-Efficiency Processing

• ARM Cortex-M3 Core: Supports Thumb-2 instruction set for optimized code density and execution efficiency.
• 120 MHz Clock Speed: Delivers robust processing power for complex algorithms and real-time control.
• Memory Protection Unit (MPU): Enhances system security by safeguarding critical memory regions.

Rich Peripheral Integration

• Communication Interfaces:
  • 10/100M Ethernet MAC (RMII interface, external PHY required)
  • USB 2.0 OTG (Host/Device support)
  • 4x UART (with fractional baud rate generation and IrDA support)
  • 3x I2C (1x Fast-mode Plus up to 1 Mbit/s), 2x SPI, 2x CAN 2.0B
• Analog Capabilities:
  • 8-channel 12-bit ADC with 200 kHz conversion rate and DMA support
  • 10-bit DAC with dedicated conversion timer
• Timers & PWM:
  • 4x 32-bit general-purpose timers, 6-output PWM for motor control
  • Quadrature encoder interface for motion control applications

Low-Power Design

• Multi-Power Modes: Sleep, Deep-sleep, Power-down, and Deep-power-down modes reduce power consumption; typical active mode current as low as 200 μA/MHz.
• Wide Voltage Range: Operates from 2.4V to 3.6V, suitable for battery-powered and low-voltage applications.

Industrial-Grade Reliability

• Temperature Range: -40°C to +85°C, ensuring stable operation in harsh environments.
• EMC Immunity: Robust design for interference resistance in industrial settings.

Technical Specifications

Typical Applications

• Industrial Control: PLCs, motor drives, HMI interfaces, and industrial networking.
