C8051F017-GQR

Overview

The C8051F017-GQR is a mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a high-speed 8051 CPU core with up to 25 MIPS throughput at 25 MHz. It integrates 32 KB of ISP Flash memory and 2304 bytes of internal SRAM. The device includes a 10-bit SAR ADC with programmable gain amplifier, two 12-bit DACs, analog comparators, and a precision voltage reference. Digital peripherals include hardware SMBus, SPI, UART, four 16-bit timers, and a Programmable Counter Array. It operates on a 2.7V to 3.6V supply in a 64-pin TQFP package.

Feature Summary

• On-chip JTAG debug circuitry enables full-speed, non-intrusive in-system debugging without external emulation hardware.
• Integrated mixed-signal peripherals include a 10-bit ADC with data-dependent windowed interrupt generator and dual 12-bit DACs.
• Hardware serial interfaces allow concurrent operation of SMBus, SPI, and UART ports.
• Pipelined instruction architecture executes 70% of the instruction set in one or two system clock cycles.

Applications

• In-system programming and firmware development using Keil µVision software
• Mixed-signal control systems requiring simultaneous analog-to-digital conversion and digital I/O processing
• Industrial monitoring applications utilizing built-in temperature sensors and voltage comparators

Procurement Notes

Verify component authenticity through authorized Silicon Laboratories distributors. Confirm the specific GQR suffix corresponds to the 64-pin TQFP package variant. Ensure compatibility with existing design infrastructure before procurement, as this series is marked not recommended for new designs. Validate that the required flash capacity and peripheral sets align with project specifications.

Selection Notes

Select this model when a complete mixed-signal solution is required within a single chip. The C8051F017 provides sufficient memory and analog capabilities for complex embedded tasks. Consider the 64-pin form factor for expanded I/O requirements. Evaluate power consumption profiles against application needs, noting typical operating current values at maximum clock speeds.

Part Context

This component belongs to the C8051F0xx mixed-signal MCU family, which shares a common architectural foundation including the CIP-51 CPU core and crossbar logic. Variants within this family differ primarily in memory sizes, ADC resolution, and available pin counts. The F017 specifically offers higher RAM capacity compared to base models like the F000 series.
