C8051F562-IM

Overview

The C8051F562-IMR is an automotive-grade, mixed-signal microcontroller from Silicon Labs' C8051F56x family. It features a high-speed 8-bit CIP-51 core operating at up to 50 MIPS with a 50 MHz clock. The device integrates 32 kB of in-system programmable Flash memory and 2.25 kB of internal data RAM (256 + 2048 XRAM). Key analog peripherals include a 12-bit ADC with up to 200 ksps sampling rate and two comparators. Digital interfaces encompass CAN 2.0, LIN 2.1, UART, SMBus, and SPI. 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 qualified compliance with AEC-Q100 standards for robust operation in demanding environments.
• Integrated CAN 2.0 and LIN 2.1 controllers enabling direct network connectivity without external transceivers or crystals.
• High-performance CIP-51 architecture executing 70% of instructions in one or two system clocks for efficient processing.
• On-chip debug circuitry supporting full-speed, non-intrusive in-system debugging without requiring separate emulator hardware.

Applications

• Automotive body control modules and sensor interface units
• Industrial communication gateways utilizing CAN and LIN protocols
• Battery management systems requiring precise analog monitoring
• Motor control applications leveraging PWM and timer capabilities

Procurement Notes

Verify the specific suffix 'IMR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets the AEC-Q100 qualification requirements mandated by your target automotive application specifications. Ensure compatibility with existing design infrastructure regarding the 32-pin QFN package dimensions and thermal characteristics.

Selection Notes

Select this model when automotive reliability is mandatory alongside integrated CAN/LIN bus connectivity. The 32 kB Flash capacity suits firmware-heavy applications, while the 12-bit ADC resolution supports precision sensing tasks. Consider the 50 MIPS throughput for real-time control loops. Evaluate pin count constraints as this variant offers 33 digital I/O lines within a compact footprint suitable for space-constrained PCB layouts.

Part Context

This component belongs to the C8051F56x series, designed specifically for automotive and industrial sectors. It shares architectural similarities with the C8051F55x and C8051F57x families but distinguishes itself through optimized peripheral sets for vehicle networks. The series emphasizes system-on-chip integration, reducing external component counts and simplifying board design for cost-sensitive mass production.

Replacement Considerations

Consult official documentation for pin-compatible alternatives within the C8051F55x/56x/57x family. Verify functional equivalence regarding CAN/LIN controller availability and Flash size before substituting. Note that newer designs may require migration to current Silicon Labs MCU portfolios due to end-of-life status.
