C8051F017

Overview

The C8051F017 is a mixed-signal System-on-Chip microcontroller from Silicon Labs, featuring a high-speed CIP-51 core operating at up to 25 MIPS with a 25 MHz clock. It integrates 32 KB of ISP Flash memory and 256 bytes of internal SRAM. The device includes a 10-bit SAR ADC with programmable throughput up to 100 ksps, two 12-bit DACs, and two analog comparators. Digital peripherals consist of hardware SMBus, SPI, and UART interfaces alongside a Programmable Counter Array. It operates on a supply voltage of 2.7V to 3.6V within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a pipelined 8051 CPU architecture capable of executing the majority of instructions in one or two system clock cycles for high throughput.
• Features a fully integrated JTAG debug circuitry that supports full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Includes a programmable digital I/O crossbar decoder allowing flexible assignment of peripheral functions to physical pins.
• Provides on-chip analog resources including a precision voltage reference, temperature sensor, and brown-out detector.

Applications

• Industrial control systems requiring mixed-signal processing
• Data acquisition applications utilizing onboard ADC and DAC capabilities
• Embedded USB or serial communication devices using concurrent SMBus/SPI/UART ports

Procurement Notes

Verify the specific package variant (TQFP-64, TQFP-48, or LQFP-32) required for your design, as the datasheet covers multiple form factors for this part number. Confirm RoHS compliance status and ensure the ordering suffix matches the desired temperature grade and packaging style. Cross-reference the pinout diagrams in the official documentation to validate footprint compatibility before finalizing procurement.

Selection Notes

Select the C8051F017 when a design requires a balance of moderate code space and integrated analog peripherals. This model is suitable for applications needing 10-bit ADC resolution rather than the 12-bit version found in the F00x series. Consider this part if the project benefits from the specific 256-byte RAM configuration and does not require the larger memory capacity of the F005/06/07 variants.

Part Context

This component belongs to the C8051F0xx family of mixed-signal MCUs, which are distinguished by their high integration levels and ISP Flash technology. The F017 variant specifically differentiates itself within the family by offering 10-bit ADC resolution compared to the 12-bit resolution of the F00x counterparts, while sharing the same 32 KB Flash and core architecture.

Replacement Considerations

C8051F010: Offers identical specifications but with 10-bit ADC resolution instead of 12-bit. C8051F012: Provides the same core and memory but with 10-bit ADC resolution. C8051F007: Features 12-bit ADC resolution and 2304 bytes of RAM, requiring software adaptation for memory differences.
