C8051F527-C-IMR

Overview

The C8051F527-C-IMR is an automotive-grade, 8-bit microcontroller from Silicon Labs' C8051F52x family. It features a high-speed CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device integrates 2 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. Key peripherals include a 12-bit ADC with 200 ksps throughput, a hardware SPI port, a UART, and a LIN 2.1 controller. It operates within a supply voltage range of 2.0 V to 5.25 V and supports an extended temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust industrial and vehicle applications
• Integrated 12-bit analog-to-digital converter supporting programmable throughput and windowed interrupts
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Hardware LIN 2.1 controller capable of master and slave operations without requiring an external crystal

Applications

• Motor control systems
• Sensor interface circuits
• Parking assistance modules
• Seat position and adjustment controllers
• Fluid level monitoring units

Procurement Notes

Verify the specific suffix 'C-IMR' against the manufacturer's current ordering guide to confirm package type and tape-and-reel specifications. Confirm that the component status remains active or note End-of-Life implications if applicable. Ensure compatibility with existing PCB footprints for the DFN-10 package before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability and LIN bus connectivity are required in a compact form factor. The integrated 12-bit ADC and comparator support precise signal conditioning needs. Consider the limited 2 kB Flash capacity for complex firmware requirements. Verify that the 256-byte RAM suffices for real-time data processing tasks.

Part Context

This part belongs to the C8051F52x/F53x family of mixed-signal microcontrollers. These devices are designed for cost-sensitive applications requiring high integration. The family utilizes the CIP-51 architecture, which offers enhanced performance over traditional 8051 cores while maintaining instruction set compatibility. This specific model targets automotive environments due to its wide temperature rating.
