C8051F565-IM

Overview

The C8051F565-IM is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F56x family, featuring a high-speed CIP-51 core operating at up to 50 MHz. It integrates 16 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM (256 + 2048 XRAM). The device includes a 12-bit ADC with up to 200 ksps throughput, two comparators, and multiple digital peripherals including 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 automotive qualification standards.

Feature Summary

• Integrated 12-bit analog-to-digital converter with selectable gain and built-in temperature sensor
• Hardware-accelerated communication interfaces including CAN 2.0 and LIN 2.1 controllers without external crystals
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging via C2 interface
• Pipelined instruction architecture executing 70% of instructions in one or two system clocks

Applications

• Automotive body control modules requiring AEC-Q100 compliance
• Industrial monitoring systems utilizing high-speed ADC and comparator inputs
• Networked devices implementing CAN or LIN bus protocols for master/slave communication
• Portable instrumentation powered by low-voltage supplies within the 1.8 V to 5.25 V range

Procurement Notes

Verify component authenticity through authorized distributors as this part is designated Not Recommended for New Designs. Confirm package integrity upon receipt, specifically checking for QFN-32 solder joint quality. Ensure design reviews account for the obsolescence status when planning long-term production runs. Cross-reference datasheet revision 1.4 for any errata updates prior to final implementation.

Selection Notes

Select this model when specific pin counts and peripheral sets of the C8051F56x series are required. Compare against C8051F55x and C8051F57x variants to match exact memory sizes and I/O configurations. Evaluate power consumption requirements against typical stop mode currents if battery operation is critical. Ensure software tools support the CIP-51 architecture for efficient development cycles.

Part Context

This component belongs to the C8051F55x/56x/57x family of mixed-signal ISPs. These devices share a common architectural foundation but differ in memory capacity and pin count. The C8051F565-IM specifically utilizes a 32-pin QFN package, distinguishing it from the 24-pin and 40-pin options available in the broader family lineup.

Replacement Considerations

C8051F565-IM is obsolete; consider C8051F56x derivatives with updated availability or migrate to newer Silicon Labs MCU families such as EFM8 or C8051T.
