C8051F017-GQ

Overview

The C8051F017-GQ is a mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a high-speed 8051 CPU core capable of up to 25 MIPS. It integrates 32KB of ISP Flash memory and 2304 bytes of internal SRAM. The device includes a 10-bit SAR ADC with programmable throughput up to 100ksps, two 12-bit DACs, and two analog comparators. Digital peripherals include hardware SMBus, SPI, and UART interfaces alongside four general-purpose 16-bit timers. Operating within a supply voltage range of 2.7V to 3.6V, it supports multiple power-saving modes and features on-chip JTAG debug circuitry.

Procurement Notes

Verify component authenticity by checking for manufacturer markings and datasheet revision consistency. Confirm package type matches the specific suffix requirements. Ensure compliance with RoHS directives if applicable. Note that this product family is marked as not recommended for new designs; evaluate alternative solutions for long-term projects. Validate operating temperature ranges against environmental specifications.

Selection Notes

Select this model when existing system architectures utilize the C8051F0xx family. Consider the 10-bit ADC resolution and 2304-byte RAM capacity for memory-intensive tasks. Evaluate the 2.7V to 3.6V supply requirement against available power rails. Assess the need for concurrent serial interface usage and on-chip debug capabilities during design phase.

Part Context

This component belongs to the Silicon Labs C8051F0xx mixed-signal MCU family, which shares common architectural features such as the CIP-51 CPU core and crossbar logic. Variants within the family differ primarily in ADC resolution (10-bit vs 12-bit) and SRAM size. The GQ suffix typically denotes a specific package configuration, likely TQFP, though exact pin counts vary by family member.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the C8051F0xx family is designated as not recommended for new designs, consult Silicon Laboratories for current equivalent recommendations or migration paths to supported families.
