C8051F526-IM

Overview

The C8051F526-IM is an automotive-grade, 8-bit microcontroller from the Silicon Labs C8051F52x family. It features a high-speed 8051 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 2 kB of in-system programmable Flash memory and 256 bytes of internal RAM. Key peripherals include a 12-bit ADC with 200 ksps throughput, a LIN controller, SPI, UART, and three 16-bit timers. 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 automotive environments
Integrated LIN 2.1 controller supporting both master and slave modes without requiring external crystals
On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging via the C2 interface

Applications

LIN bus communication nodes in automotive networks
Industrial sensor interfaces requiring analog signal processing
Motor control applications utilizing timer and PWM capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the QFN and DFN variants are sensitive to moisture and physical damage. Ensure that the specific suffix matches the required pinout and thermal characteristics for your PCB layout design.

Selection Notes

Select this model when automotive reliability and compact form factors are critical. The integrated LIN controller simplifies network implementation compared to standard UART solutions. Consider the 2 kB Flash limit for complex firmware requirements; larger memory variants may be necessary for extensive application logic.

Part Context

This component belongs to the C8051F52x/F53x series, designed specifically for space-constrained automotive and industrial systems. The family emphasizes high integration by combining analog peripherals, digital I/O, and communication interfaces into small packages like the 10-pin DFN and 20-pin QFN.
