Overview
The C8051F534-C-IT is an automotive-qualified, 8-bit microcontroller from the Silicon Labs C8051F52x/F53x family. It features a high-speed CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device integrates 4 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 comparator, and a LIN 2.1 controller. It supports supply voltages from 2.0 V to 5.25 V and operates within a temperature range of –40 °C to +125 °C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for extended industrial temperature ranges.
- Integrated LIN 2.1 controller supporting both master and slave modes without requiring an external crystal.
- High-precision internal oscillator with ±0.5% accuracy suitable for UART and LIN-Master operations.
- On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging.
Applications
- Automotive body control modules
- LIN bus network nodes
- Industrial sensor interfaces
Procurement Notes
Verify component authenticity through authorized channels. Confirm package integrity and pin alignment against TSSOP-20 specifications. Review the datasheet revision history for any errata or silicon revisions that may impact design implementation. Ensure compliance with RoHS directives and automotive quality requirements before integration.
Selection Notes
Select this part when automotive reliability and LIN communication are required. The integrated voltage reference and comparator simplify analog signal conditioning. Consider the 4 kB Flash limit for complex applications. Verify power supply stability within the 2.0 V to 5.25 V range to ensure proper operation of the internal LDO regulator.
Part Context
This component belongs to the C8051F52x/F53x series of mixed-signal microcontrollers. It utilizes the CIP-51 architecture, which offers enhanced performance over traditional 8051 cores. The series is designed for cost-sensitive applications requiring high integration and low latency. The specific suffix indicates automotive grade qualification and TSSOP-20 packaging.
Replacement Considerations
Consult the manufacturer's product selection guide for direct substitutes within the C8051F53x family. Verify pin compatibility and peripheral availability when considering alternative packages or memory sizes. Check for end-of-life notices on current inventory.
