C8051F061-GQ

Overview

The C8051F061-GQ is an analog-intensive mixed-signal microcontroller from Silicon Labs, featuring a high-speed 8051 core operating at up to 24.5 MHz with 25 MIPS throughput. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key peripherals include two 16-bit SAR ADCs capable of 1 Msps, a 10-bit SAR ADC, two 12-bit DACs, three analog comparators, and a Bosch CAN 2.0B controller. The device provides 24 general-purpose I/O pins, supports multiple serial interfaces including UART, SPI, and SMBus, and operates within a supply voltage range of 2.7 V to 3.6 V across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual 16-bit SAR ADCs with direct memory access for high-speed data acquisition without software overhead.
• Includes a hardware Bosch CAN 2.0B controller for robust automotive and industrial network communication.
• Features on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-circuit debugging and boundary scan capabilities.

Applications

• Industrial control systems requiring precise analog signal processing
• Automotive embedded networks utilizing CAN bus protocols
• Portable medical equipment and test instrumentation

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm that the component meets RoHS standards if required by your assembly process. Check for any manufacturer notices regarding end-of-life status or recommended design alternatives before finalizing procurement plans.

Selection Notes

Select this model when high-resolution analog conversion and CAN connectivity are required in a single chip. Ensure the 24 GPIO count suffices for your interface needs, as other variants offer more pins. Verify that the 2.7V to 3.6V supply range aligns with your system power architecture.

Part Context

This component belongs to the C8051F06x family of highly integrated mixed-signal microcontrollers. These devices are designed as standalone system-on-chip solutions, combining a fast 8051 CPU with extensive analog and digital peripherals to reduce external component counts in embedded designs.

Replacement Considerations

Silicon Laboratories has marked the C8051F06x family as Not Recommended for New Designs. Consult official documentation for current recommended replacements or alternative product lines suitable for new development projects.
