C8051F534-IM

Overview

The C8051F534-IM is an automotive-grade, 8-bit mixed-signal microcontroller from Silicon Labs. It features a high-speed 8051 core operating at up to 25 MHz with 25 MIPS throughput. The device integrates 4 kB of in-system programmable Flash memory and 256 bytes of internal RAM. Key peripherals include a 12-bit ADC with up to 200 ksps throughput, a LIN 2.1 controller, hardware SPI, and UART interfaces. It operates within a supply voltage range of 2.0 V to 5.25 V and supports an industrial temperature range of -40°C to +125°C.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards for robust operation in demanding environments.
Integrated LIN 2.1 controller supporting both master and slave modes without requiring an external crystal.
On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.

Applications

LIN bus communication nodes in automotive networks
Industrial sensor interface modules
Motor control applications

Procurement Notes

Verify the specific suffix 'IM' corresponds to the 20-pin QFN package (4x4 mm) as defined in the datasheet. Confirm that the component meets the required AEC-Q100 automotive grade specifications if deployed in vehicle systems. Check current lifecycle status, as this part may be subject to end-of-life notices.

Selection Notes

Select this MCU when a small form factor is required alongside automotive reliability. The integrated LIN controller simplifies network design by removing the need for external transceivers or crystals. Ensure the 4 kB Flash capacity meets application code requirements before choosing over larger variants in the F53x family.

Part Context

This component belongs to the C8051F52x/F53x family of mixed-signal microcontrollers. These devices are designed to provide high performance and low power consumption in compact packages. The family shares common architectural features, including the CIP-51 core and extensive analog peripherals, tailored for cost-sensitive embedded applications.
