C8051F341-GQR

Overview

The C8051F341-GQR is an 8-bit mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F34x family. It features a high-speed pipelined 8051 core operating at 48 MIPS, paired with 32 kB of in-system programmable Flash memory and 2304 bytes of RAM. The device integrates a full-speed USB 2.0 function controller with an integrated transceiver and clock recovery circuitry. Digital peripherals include four 16-bit timers, a Programmable Counter Array (PCA), SPI, SMBus, and dual UARTs. The unit operates within a voltage range of 2.7 V to 5.25 V and supports industrial temperature ranges.

Feature Summary

• Integrates a high-performance 48 MIPS 8051-compatible core with on-chip debug capabilities for non-intrusive system debugging.
• Includes a fully compliant USB 2.0 function controller with integrated transceiver and clock recovery, eliminating external components.
• Features flexible digital communication interfaces including hardware-enhanced SPI, SMBus, and multiple UART ports.
• Provides versatile analog and timing resources such as a Programmable Counter Array with capture/compare modules and general-purpose timers.

Applications

• USB-enabled PC peripherals and point-of-sale terminals
• Embedded modems and voice over Internet Protocol (VoIP) telephones
• Medical diagnostic equipment requiring mixed-signal processing
• Weigh scales and portable instrumentation

Procurement Notes

Verify component status before procurement as this series is marked Not Recommended for New Designs. Confirm package type matches the required footprint, specifically the 48-pin TQFP variant for this model. Ensure design reviews account for end-of-life planning given the manufacturer's recommendation against new implementations.

Selection Notes

Select this model when a 32 kB Flash capacity suffices for firmware requirements, distinguishing it from the 64 kB variants in the same family. Verify that the 48 MHz core speed meets processing needs compared to lower-frequency options. Check peripheral availability, noting that specific analog features like the 10-bit ADC are reserved for other members of the C8051F34x series.

Part Context

This component belongs to the C8051F34x Full Speed USB Flash MCU family produced by Silicon Laboratories. The family provides mixed-signal SoC solutions designed for applications demanding USB connectivity alongside robust CPU performance. The C8051F341-GQR specifically utilizes the 48-pin TQFP package configuration within this lineup.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate newer Silicon Labs MCU families or alternative vendors for long-term supply assurance due to the 'Not Recommended for New Designs' status.
