C8051F583-IQ

Overview

The C8051F583-IQ is an automotive-qualified mixed-signal ISP Flash MCU from Silicon Labs, featuring a high-speed 8051 core with up to 50 MIPS throughput at a 50 MHz clock. It integrates 128 kB of banked Flash memory and 8448 bytes of internal data RAM. The device includes a 12-bit ADC supporting up to 200 ksps, three comparators, CAN 2.0 and LIN 2.1 controllers, two UARTs, and SPI ports. 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-grade qualification compliant with AEC-Q100 standards for extended temperature operation.
• Integrated CAN 2.0 and LIN 2.1 controllers enabling direct network connectivity without external crystals.
• On-chip debug circuitry providing full-speed, non-intrusive in-system debugging capabilities.

Applications

• Automotive sensor interface systems
• Industrial motor control applications
• Embedded communication gateways

Procurement Notes

Verify the current lifecycle status before procurement as this component may be marked Not Recommended for New Designs. Confirm package availability and ensure compatibility with existing design constraints given potential obsolescence timelines.

Selection Notes

Select this MCU for designs requiring robust automotive compliance and integrated serial bus controllers. Evaluate the 128 kB Flash capacity against application firmware size requirements. Consider the 32-pin QFP/QFN package dimensions for PCB layout optimization.

Part Context

This part belongs to the C8051F58x/F59x family of mixed-signal microcontrollers. It shares architectural similarities with the C8051F50x and C8051F51x series, offering pin-for-pin compatibility within specific package configurations to facilitate migration between different memory variants.

Replacement Considerations

Silicon Labs recommends the EFM8BB31F64I-QFN32 as a replacement for related obsolete parts in this family. Verify functional equivalence and pinout compatibility before substituting.
