C8051F562-IQ

Overview

The C8051F562-IQ is an automotive-qualified, mixed-signal ISP Flash MCU from the C8051F56x family. It features a high-speed 8051 core with up to 50 MIPS throughput and 32 kB of in-system programmable Flash memory. The device integrates a 12-bit ADC supporting up to 200 ksps sampling rate and up to 32 external single-ended inputs. Digital peripherals include CAN 2.0 and LIN 2.1 controllers without requiring external crystals, alongside hardware UART, SMBus, and SPI interfaces. It operates on a supply voltage of 1.8 V to 5.25 V within a temperature range of –40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliable operation in demanding environments.
• Integrated CAN 2.0 and LIN 2.1 communication controllers that eliminate the need for external crystal oscillators.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without additional emulation hardware.
• High-performance pipelined 8051 core executing 70% of instructions in one or two system clocks.

Applications

• Automotive body control modules
• Industrial sensor nodes
• LIN/CAN bus gateway devices

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors. Confirm the specific ordering suffix matches the required package type and temperature grade. Check for current availability status as this series may be subject to lifecycle changes. Ensure design compliance with AEC-Q100 requirements if used in automotive contexts.

Selection Notes

Select this model when automotive reliability and integrated LIN/CAN connectivity are required without external clock components. Consider the 32 kB Flash capacity and 12-bit ADC resolution against application data logging needs. Evaluate the 40-pin QFN package constraints for PCB layout. Compare power consumption in stop mode against battery-operated system requirements.

Part Context

This component belongs to the C8051F55x/56x/57x mixed-signal microcontroller family. These devices are designed as complete system-on-a-chip solutions, integrating analog peripherals, digital interfaces, and a high-speed CPU. The family emphasizes pin-for-pin compatibility across different memory configurations to simplify product line extensions.

Replacement Considerations

Consult the official datasheet for pin-compatible alternatives within the C8051F56x series. Verify that substitute parts maintain identical package dimensions and electrical characteristics. Cross-reference specific ordering suffixes to ensure matching thermal and voltage ratings.
