C8051F043-GQ

Overview

The C8051F043-GQ is an 8-bit microcontroller from the Silicon Labs C8051F04x family, featuring a CIP-51 core with up to 25 MIPS throughput at 25 MHz. It includes 64 kB of in-system programmable Flash and 4352 bytes of internal data RAM. The device integrates a 10-bit SAR ADC with 13 external inputs, two 12-bit DACs, three analog comparators, and a precision voltage reference. Digital peripherals include CAN 2.0B, SMBus, SPI, and dual UARTs.

Feature Summary

Integrated full-speed USB 2.0 controller for host or device applications
On-chip JTAG debug circuitry supporting non-intrusive in-circuit debugging
Programmable digital crossbar allows flexible pin assignment for peripherals
Multiple power-saving sleep and shutdown modes for low-power operation

Applications

Industrial control systems requiring CAN communication
Data acquisition systems utilizing high-resolution ADCs
Embedded modems and voice over IP telephones
Medical diagnostic equipment and point-of-sale terminals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and absence of physical damage upon receipt. Ensure compatibility with existing design specifications regarding voltage levels and interface requirements before integration into production systems.

Selection Notes

Select this model when specific analog features like dual 12-bit DACs and a 10-bit ADC are required alongside standard digital interfaces. Consider the 64 kB Flash capacity for complex firmware needs. Evaluate power consumption profiles against application requirements given the available sleep modes.

Part Context

This component belongs to the C8051F04x series of mixed-signal system-on-chip microcontrollers. It shares architectural similarities with other members of the family but offers distinct peripheral configurations tailored for cost-sensitive and high-performance applications within the broader embedded control market.
