C8051F536A-ITR

Overview

The C8051F536A-ITR is an automotive-qualified, fully integrated mixed-signal System-on-a-Chip microcontroller from Silicon Laboratories. It features a high-speed CIP-51 core operating at up to 25 MIPS with a 25 MHz system clock. The device includes 2 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. Key peripherals include a 12-bit ADC with up to 200 ksps throughput, a hardware LIN 2.1 controller, SPI, and UART interfaces. It operates within a supply voltage range of 2.0 V to 5.25 V and supports an industrial temperature range of –40 °C to +125 °C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for robust operation in demanding environments.
• Integrated LIN 2.1 controller supporting both master and slave modes without requiring external crystals.
• High-performance CIP-51 architecture delivering up to 25 MIPS throughput via pipelined instruction execution.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.

Applications

• Automotive body control modules and sensor interface units
• Industrial communication gateways utilizing LIN bus protocols
• Embedded systems requiring precise analog signal acquisition via the 12-bit ADC
• Cost-sensitive embedded controllers needing integrated flash programming capabilities

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Ensure design compliance with the specified electrical characteristics and thermal limits. Review the latest datasheet revision for any errata or pinout updates before finalizing PCB layouts.

Selection Notes

Select this component when automotive reliability and LIN bus integration are required. The 2 kB Flash capacity suits applications with moderate code size requirements. Verify that the 256-byte RAM suffices for real-time data processing needs. Consider the TSSOP-20 package constraints regarding thermal dissipation and available board space for the specific enclosure design.

Part Context

This part belongs to the C8051F52x/F53x family of mixed-signal microcontrollers.
