C8051F568-IM

Overview

The C8051F568-9 is an automotive and industrial mixed-signal ISP Flash MCU from the C8051F56x family, manufactured by Silicon Labs. It features a high-speed 8051 core delivering up to 50 MIPS at a 50 MHz clock frequency. The device integrates 32 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM. 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 within a supply voltage range of 1.8 V to 5.25 V and supports a temperature range of –40 °C to +125 °C, compliant with AEC-Q100 standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 for extended temperature operation
• Integrated CAN 2.0 and LIN 2.1 controllers enabling direct network connectivity without external crystals
• On-chip debug circuitry supporting full-speed, non-intrusive in-system debugging
• High-performance pipelined 8051 core executing 70% of instructions in one or two system clocks

Applications

• Automotive body control modules
• Industrial communication gateways
• Sensor interface nodes requiring LIN/CAN connectivity
• Embedded systems needing in-circuit reprogrammability

Procurement Notes

Verify the specific ordering suffix '-9' corresponds to the 40-pin QFN package variant. Confirm that the component status is acceptable for current designs, as the datasheet indicates this family is not recommended for new designs. Ensure compatibility with existing PCB footprints and validate that the AEC-Q100 grade meets project requirements.

Selection Notes

Select this model when automotive reliability and integrated LIN/CAN capabilities are required in a compact form factor. Consider the 32 kB Flash size and 2304 bytes RAM against application memory needs. Evaluate the 40-pin QFN package constraints for thermal management and board space. Verify that the 1.8 V to 5.25 V supply range aligns with the system power architecture.

Part Context

This part belongs to the C8051F55x/56x/57x Mixed Signal ISP Flash MCU family. The C8051F56x series specifically targets automotive and industrial applications, offering pin-for-pin compatibility with other members of the family. It shares the same core architecture and peripheral set as the C8051F55x and C8051F57x, differentiated primarily by memory size and package options.
