C8051F590-IMR

Overview

The C8051F590-IMR is a mixed-signal ISP Flash MCU from the C8051F58x/F59x family, featuring a high-speed 8051 core with up to 50 MIPS throughput at 50 MHz. It includes 96 kB of banked Flash memory and 8448 bytes of internal data RAM. Key analog peripherals comprise a 12-bit ADC with up to 200 ksps sampling rate and three comparators. Digital interfaces include CAN 2.0 and LIN 2.1 controllers without external crystals, two UARTs, SMBus, and SPI. The device operates on a supply voltage of 1.8 to 5.25 V and supports automotive temperature ranges from –40 to +125 °C.

Feature Summary

• Integrated CAN 2.0 and LIN 2.1 controllers eliminate the need for external crystal oscillators.
• On-chip debug circuitry enables full-speed, non-intrusive in-system debugging without external emulators.
• High-speed pipelined 8051 core executes 70% of instructions in one or two system clocks.
• Automotive qualified performance with extended temperature range support.

Applications

• Automotive body control modules
• Industrial motor control systems
• In-vehicle network communication nodes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm that the component meets RoHS compliance requirements for your region. Check for any end-of-life notices as this family is marked not recommended for new designs. Ensure compatibility with existing development tools and programming interfaces before procurement.

Selection Notes

Select this part when automotive qualification and integrated CAN/LIN connectivity are required without external clock components. Consider the 96 kB Flash size and 12-bit ADC resolution for applications needing moderate processing power and precise analog signal acquisition. Evaluate the 40-pin QFN package constraints for PCB layout if space is limited. Compare power consumption in stop mode against other MCUs if battery life is critical.

Part Context

This microcontroller belongs to the Silicon Labs C8051F58x/F59x mixed-signal ISP Flash MCU family. It shares architectural similarities with other members like the C8051F58x series but offers specific memory and peripheral configurations tailored for robust embedded control. The family emphasizes ease of development through on-chip debugging and in-system programmability.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the C8051F58x/F59x family is marked 'Not Recommended for New Designs', consult Silicon Laboratories for current alternative recommendations or legacy support options.
