C8051F580-IM

Overview

The C8051F580-IM is an 8-bit mixed-signal ISP Flash MCU from the Silicon Labs C8051F58x family, housed in a 48-QFN (7x7) package. It features a high-speed pipelined 8051 core delivering up to 50 MIPS at a 50 MHz clock speed. The device integrates 128 KB of banked Flash memory and 8448 bytes of internal data RAM (including 8192 bytes of XRAM). Key analog peripherals include a 12-bit ADC with up to 200 ksps throughput, three comparators, and a built-in temperature sensor. Digital interfaces encompass CAN 2.0, LIN 2.1, two UARTs, SMBus, and SPI. It operates on a supply voltage of 1.8 V to 5.25 V and supports an industrial temperature range of –40 °C to +125 °C.

Feature Summary

• High-speed 8051 microcontroller core with pipelined architecture for efficient instruction execution.
• Integrated 12-bit analog-to-digital converter with programmable gain and multiple input channels.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Automotive qualified design supporting wide operating temperatures and robust digital communication controllers.

Applications

• Industrial control systems requiring mixed-signal processing
• Automotive electronic modules utilizing CAN and LIN bus protocols
• Smart instrumentation and sensor interface applications
• Data acquisition systems needing high-resolution analog conversion

Procurement Notes

Verify the specific suffix 'IM' corresponds to the 48-QFN package variant when ordering. Confirm that the component status aligns with project requirements, as this family may be marked as not recommended for new designs. Ensure compatibility with existing development tools and verify that the automotive qualification meets specific industry standards if applicable to the target application environment.

Selection Notes

Select this model when a complete system-on-chip solution is needed to reduce bill-of-materials count. The integrated CAN and LIN controllers eliminate the need for separate transceivers or external protocol chips. Consider the 12-bit ADC resolution and speed for precision measurement tasks. Evaluate the 50 MIPS performance against computational demands to ensure adequate headroom for real-time control loops.

Part Context

This component belongs to the C8051F58x/F59x mixed-signal ISP Flash MCU family by Silicon Laboratories.
