C8051F530A-ITR

Overview

The C8051F530A-ITR is an automotive-grade 8-bit microcontroller from the Silicon Labs C8051F52x/F53x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz system clock. It integrates 8 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. The device includes a 12-bit ADC with programmable throughput up to 200 ksps, a LIN 2.1 controller, hardware SPI, and UART interfaces. Operating within a supply voltage range of 2.0 V to 5.25 V and a temperature range of –40 °C to +125 °C, it is housed in a 20-pin TSSOP package.

Feature Summary

• Automotive qualified to AEC-Q100 standards for reliability in harsh environments
• Integrated LIN 2.1 controller supporting both master and slave modes without external crystals
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging
• High precision internal oscillator with ±0.5% accuracy for stable timing

Applications

• Automotive body control modules
• Industrial sensor nodes requiring LIN communication
• Battery management systems
• HVAC controllers in vehicles

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required tape-and-reel packaging format. Check current lifecycle status as this series may be subject to obsolescence notices. Ensure environmental compliance documentation aligns with project requirements.

Selection Notes

Select this model when automotive qualification and LIN bus integration are mandatory. Compare against the standard C8051F530 variant if industrial grade suffices. Consider pin count and peripheral availability relative to the 20-pin TSSOP footprint. Evaluate power consumption profiles across active and sleep modes for battery-operated applications.

Part Context

This component belongs to the C8051F52x/F53x family of ISP Flash MCUs designed for cost-sensitive embedded applications. The 'A' designation indicates silicon revision A, while 'ITR' specifies the 20-pin TSSOP package with tape-and-reel shipping. It shares architectural similarities with other members of the C8051F series but offers distinct automotive certifications.
