C8051F582-IQR

Overview

The C8051F582-IQR is a mixed-signal ISP Flash MCU from the C8051F58x family, featuring an 8-bit CIP-51 core with up to 50 MIPS throughput. It includes 128 kB of banked Flash memory and 8448 bytes of internal data RAM. The device integrates a 12-bit ADC supporting up to 200 ksps, three comparators, and automotive qualification for -40°C to +125°C operation. 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 32-pin QFP package.

Feature Summary

• Automotive qualified for extended temperature ranges
• Integrated CAN 2.0 and LIN 2.1 controllers without external crystals
• On-chip debug circuitry for full-speed non-intrusive in-system debugging
• High-speed pipelined 8051 core executing most instructions in one or two system clocks

Applications

• Automotive embedded control systems
• Industrial sensor networks requiring CAN/LIN communication
• Mixed-signal data acquisition applications
• Low-power battery-operated devices

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors. Confirm the specific suffix matches the required package type. Check official notices for end-of-life status as this model may be discontinued. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this part when automotive certification is mandatory alongside integrated CAN and LIN capabilities. Consider the 32-pin footprint constraints against the available I/O count. Evaluate power consumption profiles against the typical operating current specifications at the target clock frequency. Verify that the 128 kB Flash capacity meets application code storage needs.

Part Context

This microcontroller belongs to the C8051F58x/F59x family of mixed-signal ISPs. It shares architectural similarities with other members like the C8051F580 but differs in pin count and peripheral availability. The series represents a transition toward highly integrated single-chip solutions for industrial and automotive markets.
