Overview
The C8051F041-GQ is an 8-bit microcontroller from the Silicon Labs C8051F04x family, featuring a pipelined CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 64 kB of in-system programmable Flash and 4352 bytes of internal data RAM. Key analog peripherals include a 12-bit SAR ADC with 13 external inputs and a precision voltage reference. Digital interfaces comprise a Bosch CAN 2.0B controller, SMBus, SPI, and two UARTs. The device operates on a 2.7 V to 3.6 V supply within a -40 °C to +85 °C temperature range.
Feature Summary
- Features a high-speed 8051-compatible core executing most instructions in one or two system clocks.
- Integrates a 12-bit SAR ADC with programmable gain amplifier and windowed interrupt generation.
- Includes hardware support for Bosch CAN 2.0B, SMBus, SPI, and dual UART serial communication.
- Provides on-chip JTAG debug circuitry for non-intrusive in-circuit debugging and boundary scan.
Applications
- Industrial control systems requiring CAN bus connectivity
- Data acquisition systems utilizing high-resolution analog-to-digital conversion
- Embedded applications needing robust serial communication protocols
