C8051F805-GSR

The C8051F805-GSR is a member of Silicon Labs' C8051F80x-83x mixed-signal ISP Flash MCU family. It integrates a high-speed pipelined 8051 core capable of up to 25 MIPS throughput with a 25 MHz clock. The device includes 16KB of in-system programmable Flash memory and 512 bytes of internal data RAM. It features 13 general-purpose I/O pins, an internal oscillator, and connectivity options including SMBus (I2C-compatible), SPI, and UART/USART serial interfaces. On-chip peripherals include a 10-bit ADC with up to 12 channels, a comparator, programmable counter array (PCA) with PWM, a temperature sensor, and a watchdog timer. The microcontroller operates from a 1.8V to 3.6V supply and is specified for -40°C to +85°C temperature range. It is available in a 16-pin SOIC package (16-SOIC) for surface mount assembly. The device also features on-chip debug circuitry for non-intrusive in-system debugging, eliminating the need for an emulator. Typical applications include capacitive touch sensing, industrial control, sensor interfacing, and embedded control systems.
