C8051F047-GQR

Overview

The C8051F047-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F04x family, featuring a CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 32 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. The device includes a 10-bit SAR ADC with 13 external inputs, three analog comparators, and a precision voltage reference. Digital peripherals comprise a Bosch CAN 2.0B controller, hardware SMBus/I2C, SPI, and two UARTs. It operates on a 2.7 V to 3.6 V supply within a -40 °C to +85 °C temperature range.

Feature Summary

• High-performance pipelined 8051 core executing most instructions in one or two system clocks
• Integrated 10-bit SAR ADC with programmable gain amplifier and windowed interrupt generator
• On-chip JTAG debug circuitry supporting non-intrusive in-circuit debugging and boundary scan
• Flexible digital I/O with programmable crossbar decoder for peripheral pin assignment

Applications

• Industrial control systems requiring CAN bus communication
• Data acquisition systems utilizing high-resolution analog-to-digital conversion
• Portable instruments with low-power sleep modes
• Sensor interface applications with integrated temperature sensing

Procurement Notes

Verify component authenticity against official Silicon Labs documentation. Confirm package type matches the 100-TQFP specification. Check revision status as this family is marked Not Recommended for New Designs. Ensure environmental compliance aligns with project requirements.

Selection Notes

Select this model for designs needing 32 kB Flash and 10-bit ADC resolution. Compare with C8051F046 if different port configurations are required. Consider power consumption characteristics during active and sleep modes. Validate peripheral availability against specific application interface needs.

Part Context

This component belongs to the C8051F04x series of fully integrated mixed-signal System-on-Chip microcontrollers. It shares architectural similarities with other members like the C8051F040 and F042 but differs in memory size and ADC resolution. The GQR suffix indicates a specific tape-and-reel packaging option suitable for automated assembly processes.
