C8051F565-IQR

Overview

The C8051F565-IQR is an 8-bit mixed-signal microcontroller from the C8051F56x family, manufactured by Silicon Labs. It features a high-speed CIP-51 core operating at up to 50 MHz with 50 MIPS throughput. The device includes 16 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM (256 + 2048 XRAM). Key peripherals include a 12-bit ADC with up to 200 ksps sampling rate, two comparators, CAN 2.0 and LIN 2.1 controllers, and hardware-enhanced UART, SMBus, and SPI interfaces. It operates on a supply voltage of 1.8 V to 5.25 V and supports -40°C to +125°C automotive temperature range.

Feature Summary

• Integrated 12-bit analog-to-digital converter supporting up to 200 ksps sampling rates with selectable gain and window detection capabilities.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Hardware support for CAN 2.0 and LIN 2.1 communication protocols without requiring external crystals.
• Pipelined instruction architecture executing 70% of instructions in one or two system clocks for high throughput.

Applications

• Automotive embedded systems requiring AEC-Q100 qualification
• Industrial control applications utilizing CAN and LIN bus networks
• Data acquisition systems employing high-speed 12-bit ADCs
• Battery-powered devices leveraging low-power stop modes

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity upon receipt. Check datasheet revision status as this part is marked Not Recommended for New Designs. Ensure ESD precautions are followed during handling. Validate pin compatibility with existing PCB footprints before integration.

Selection Notes

Select this MCU for designs requiring robust automotive-grade reliability and integrated CAN/LIN connectivity. Consider the 16 kB Flash limit for complex firmware requirements. Evaluate power consumption profiles against application needs, noting typical active current at 50 MHz. Verify that the 32-pin QFN package fits the mechanical constraints of the target enclosure.
