C8051F589-IMR

Overview

The C8051F589-IMR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F58x/F59x family, featuring a high-speed 8051 core with up to 50 MIPS throughput. 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 and 32 external single-ended inputs, alongside three comparators. Communication interfaces include 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 is housed in a 40-pin QFN package.

Feature Summary

• Automotive qualified for operation across a temperature range of –40 °C to +125 °C
• Features an on-chip debug circuitry for full speed, non-intrusive in-system debugging without requiring an emulator
• Supports CAN 2.0 and LIN 2.1 controllers that operate without an external crystal
• Includes a programmable internal oscillator with ±0.5% accuracy suitable for CAN and master LIN operations

Applications

• Automotive embedded control systems
• Industrial process monitoring and control
• LIN bus network nodes
• CAN bus communication modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision level matches design requirements. Check for RoHS compliance status as indicated in official documentation. Ensure the package marking aligns with the ordered part number to prevent counterfeit risks during assembly.

Selection Notes

Select this model when automotive qualification and robust analog peripherals are required. The integrated CAN and LIN controllers simplify system design by removing external transceivers or crystals. Consider the 128 kB Flash capacity for complex firmware applications. Evaluate the 40-pin QFN footprint against available PCB space constraints.

Part Context

This component belongs to the C8051F58x/F59x mixed-signal ISP Flash MCU family. It shares pin-for-pin compatibility with other devices in the C8051F50x, C8051F51x, and C8051F58x/59x series. The family emphasizes high integration within small form factors, combining significant processing performance with extensive analog capabilities.

Replacement Considerations

Compatible substitutes within the same family include C8051F580, C8051F581, C8051F584, and C8051F585. These parts offer identical pinouts and functional specifications but may differ in Flash memory size or I/O count.
