C8051F067-GQ

Overview

The C8051F067-GQ is a mixed-signal microcontroller featuring an 8051 core operating at up to 25 MHz. It includes 32 kB Flash memory, 4352 bytes of internal RAM, and 24 general-purpose I/O pins. The device integrates two 16-bit SAR ADCs with throughput up to 1 Msps, three analog comparators, five 16-bit timers, and six PCA channels. It supports TQFP-64 packaging and operates within a voltage range of 2.7 V to 3.6 V across temperatures from -40 °C to +85 °C.

Feature Summary

• Integrates two high-speed 16-bit SAR ADCs capable of 1 Msps throughput with direct memory access support.
• Includes on-chip JTAG debug circuitry for non-intrusive in-circuit debugging and boundary scan compliance.
• Features a pipelined 8051 core executing 70% of instructions in one or two system clocks.

Applications

• High-resolution data acquisition systems
• Precision measurement instrumentation
• Industrial control applications

Procurement Notes

Verify the component status before procurement as the datasheet indicates this family is not recommended for new designs. Confirm package type and suffix compatibility with existing board layouts. Ensure supply chain sources provide authentic Silicon Labs products to avoid counterfeit risks during integration.

Selection Notes

Select this model when dual 16-bit ADC performance is required alongside standard 8051 compatibility. Compare pin counts against the C8051F060/2 variants if more GPIOs are needed. Evaluate power consumption requirements against the specified sleep modes and operating voltage limits.

Part Context

This part belongs to the C8051F06x series of highly integrated mixed-signal microcontrollers. It shares the same core architecture and peripheral set as other members like the C8051F060 and C8051F066, differing primarily in memory size and available I/O pins.

Replacement Considerations

Silicon Labs recommends alternative devices for new designs due to the end-of-life status of this family. Consult current product portfolios for compatible successors offering similar analog capabilities and interface options.

FAQ

Does the C8051F067 include a 10-bit ADC?

No, the C8051F067 does not include the 10-bit ADC found in the C8051F060/1/2/3 variants; it features two 16-bit SAR ADCs instead.

What is the maximum clock frequency?

The device supports a maximum clock frequency of 25 MHz, delivering up to 25 MIPS throughput.
