C8051F563-IQ

Overview

The C8051F563-IQ is an automotive and industrial mixed-signal ISP Flash MCU from Silicon Labs, part of the C8051F56x family. It features a high-speed 8051 core with up to 50 MIPS throughput at a 50 MHz clock frequency. The device integrates 32 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM (including 2048 bytes XRAM). Key analog peripherals include a 12-bit ADC supporting up to 200 ksps conversion speed and two comparators. Digital interfaces encompass CAN 2.0, LIN 2.1, UART, SMBus, and SPI. It operates on a supply voltage range of 1.8 V to 5.25 V and supports an operating temperature range of –40 °C to +125 °C.

Feature Summary

• Integrated CAN 2.0 and LIN 2.1 controllers for robust automotive communication without requiring external crystals.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging with breakpoint and single-stepping capabilities.
• High-performance pipelined 8051 core executing 70% of instructions in one or two system clocks for efficient processing.
• In-circuit reprogrammable Flash memory allowing field upgrades and non-volatile data storage.

Applications

• Automotive electronic control units and sensor nodes
• Industrial automation and motor control systems
• LIN bus network master and slave devices
• Portable instrumentation and data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors as this series is marked Not Recommended for New Designs. Confirm package type matches design requirements, typically QFP-32 or QFN-32. Ensure compatibility with existing firmware architectures due to potential end-of-life status. Check for specific AEC-Q100 qualification documentation if deploying in automotive environments. Validate supply voltage ranges against target application power rails.

Selection Notes

Select this model when automotive-grade reliability and integrated LIN/CAN connectivity are required within a constrained footprint. Consider the 32 kB Flash capacity for complex firmware applications. Evaluate the 12-bit ADC resolution for precision sensing needs. Verify that the 1.8 V to 5.25 V input supply aligns with system power distribution. Assess pin count availability against peripheral requirements before finalizing selection.

Part Context

This component belongs to the C8051F55x/56x/57x Mixed Signal ISP Flash MCU family by Silicon Laboratories. These devices are designed as standalone system-on-a-chip solutions featuring on-chip voltage regulators, power-on resets, and watchdog timers. The family emphasizes high integration levels suitable for space-constrained designs while maintaining broad peripheral support for mixed-signal applications.

Replacement Considerations

Pin-for-pin compatibility exists between the C8051F56x series and the C8051F55x/57x series. Cross-reference with C8051F50x/1x and C8051F54x series for alternative options within the same ecosystem. Verify memory sizes and peripheral counts match exactly when substituting to ensure functional equivalence.
