C8051F124R

Overview

The C8051F124R is an 8-bit mixed-signal microcontroller from Silicon Labs, part of the C8051F12x family. It features a high-speed 8051 core with up to 50 MIPS throughput and 128 KB of in-system programmable Flash memory. The device includes 8448 bytes of internal RAM and supports operation at 2.7V to 3.6V. Key peripherals include an 8-bit ADC with 500 ksps throughput, two 12-bit DACs, analog comparators, and multiple digital interfaces such as SMBus, SPI, and dual UARTs. It is housed in a 100-TQFP package.

Feature Summary

• Integrated 8-bit SAR ADC with programmable throughput up to 500 ksps and differential/single-ended inputs
• Two 12-bit DACs capable of synchronized timer-triggered output for jitter-free waveform generation
• On-chip JTAG debug circuitry supporting non-intrusive in-circuit debugging and boundary scan
• Hardware support for SMBus, SPI, and concurrent dual UART serial communication

Applications

• Data acquisition systems requiring high-speed analog-to-digital conversion
• Waveform generation and signal processing applications utilizing synchronized DAC outputs
• Industrial control systems needing robust digital communication interfaces
• Embedded systems requiring on-chip debugging capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notifications or last-time-buy notices prior to procurement decisions. Ensure packaging specifications match project requirements.

Selection Notes

Select this model when high-speed 8-bit ADC performance and precise 12-bit DAC synchronization are required. Consider the 100-pin TQFP package for sufficient I/O availability. Evaluate power supply constraints against the 2.7V to 3.6V operating range. Compare peripheral sets against alternative C8051F series members if specific interface counts differ.

Part Context

This component belongs to the C8051F12x series of fully integrated mixed-signal system-on-chip microcontrollers. It shares architectural similarities with other C8051F devices but distinguishes itself through specific analog peripheral configurations, including the dedicated 8-bit ADC and dual 12-bit DACs found in this variant.

Replacement Considerations

Consult official Silicon Labs documentation for verified substitute part numbers within the C8051F family. Cross-reference pinouts and peripheral compatibility before considering alternatives.
