Description:The GD32F505CGT7 is a compact yet powerful microcontroller from GigaDevice's GD32F5 series, built around an ARM Cortex-M4F core operating at 200MHz with integrated FPU for high-efficiency signal processing and control algorithms. It combines substantial memory capacity (3MB Flash and 256KB SRAM) with comprehensive connectivity features including Ethernet MAC, USB OTG, and CAN interfaces. Packaged in a space-efficient LQFP48 form factor, this MCU is engineered for applications requiring both high performance and a small footprint. With an industrial operating temperature range (-40°C to +85°C) and robust peripheral set, it delivers reliable performance for connected industrial devices, IoT edge nodes, and advanced embedded systems where board space is constrained but functionality must remain uncompromised.Features:Core: ARM® Cortex®-M4F @ 200MHz with FPU and Memory Protection Unit (MPU)Memory: 3MB embedded Flash, 256KB SRAMConnectivity:10/100M Ethernet MAC with MII/RMII interfaceUSB 2.0 Full-Speed OTG controllerCAN 2.0B interfaceMultiple USART/UART, I2C, SPI (with I2S capability) interfacesAnalog & Timers:16-channel 12-bit ADC (up to 2.6 MSPS)2-channel 12-bit DACAdvanced-control PWM timers, general-purpose timers, basic timers, watchdog timersOperating Range: 2.6V to 3.6V supply voltage, -40°C to +85°C industrial temperature rangePackage: LQFP48 (7x7mm)Security & System: CRC calculation unit, 96-bit unique ID, Real-Time Clock (RTC)Applications:Compact Industrial Control: PLC I/O modules, motor drivers, industrial sensor nodes with networkingIoT Edge & Gateway Devices: Space-constrained wired IoT gateways, protocol converters, edge computing nodesConsumer Electronics: Networked smart appliances, portable media devices, advanced remote controlsAutomotive Electronics: Compact telematics units, CAN bus data loggers, aftermarket diagnostic interfacesMedical Devices: Portable patient monitors, handheld diagnostic equipment, wearable medical sensorsPower Management: Solar micro-inverters, smart meters, compact battery management systemsBuilding Automation: Smart thermostats, lighting controllers, compact access control panels
