C8051F536-C-IM

Overview

The C8051F536-C-IM is an 8-bit microcontroller from the C8051F52x/F53x family, manufactured by Silicon Laboratories. It features a high-speed CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 2 kB of ISP Flash memory and 256 bytes of internal data RAM. Key peripherals include a 12-bit ADC with programmable throughput up to 200 ksps, a LIN 2.1 controller, hardware SPI, and UART. It operates on a supply voltage of 2.0 to 5.25 V and is available in a 20-pin QFN package.

Feature Summary

• Integrated 12-bit analog-to-digital converter with programmable throughput and windowed interrupt generation
• Built-in LIN 2.1 controller supporting both master and slave modes without requiring an external crystal
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging via the C2 interface
• High-precision internal oscillator with ±0.5% accuracy suitable for UART and LIN-Master operations

Applications

• Automotive systems requiring AEC-Q100 qualification
• Industrial control applications utilizing LIN bus communication
• Data acquisition systems employing high-resolution analog sensing
• Embedded devices needing robust in-system programming capabilities

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm the specific revision level matches project requirements, as datasheet revisions may impact electrical characteristics. Ensure the ordering suffix corresponds to the correct package type and temperature range. Request official documentation directly from the manufacturer to validate specifications before integration into production designs.

Selection Notes

Select this model when a compact 8-bit solution with integrated LIN functionality is required. The 2 kB Flash capacity suits applications with moderate code size constraints. Consider the 20-pin QFN package for space-sensitive designs. Evaluate the 256-byte RAM limit against application stack and variable requirements. Verify that the 2.0 V minimum supply voltage aligns with the system power architecture.

Part Context

This component belongs to the C8051F52x/F53x series of mixed-signal microcontrollers. These devices are designed for cost-sensitive applications requiring high integration. The family shares a common instruction set and peripheral architecture, differing primarily in memory sizes and pin counts. This specific variant offers a balance of processing speed and analog performance within a small form factor.

Replacement Considerations

Consult the official product selection guide for direct substitutes within the C8051F52x/F53x family. Variants such as C8051F530 or C8051F534 offer different memory configurations but maintain pin compatibility. Verify peripheral availability and memory size differences before substitution. Cross-reference package dimensions to ensure mechanical fit.
