Overview
The C8051F541-IQR is an automotive and industrial mixed-signal microcontroller from the C8051F54x family, manufactured by Silicon Labs. It features a high-speed 8051 core operating at up to 50 MHz with 16 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. The device includes a 12-bit ADC supporting up to 200 ksps and 25 external single-ended inputs, along with two comparators. It offers 25 digital I/O pins that are 5 V tolerant and supports communication interfaces including LIN 2.1, UART, SMBus, and SPI. The component is qualified to AEC-Q100 standards for operation between -40 °C and +125 °C.
Feature Summary
- Integrated 12-bit analog-to-digital converter with up to 200 ksps sampling rate and built-in temperature sensor
- Hardware-enhanced serial communication peripherals including LIN 2.1 controller, UART, SMBus, and SPI
- On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
- Automotive-grade qualification compliant with AEC-Q100 specifications for extended temperature ranges
Applications
- Motor control systems
- Sensor interface circuits
- Parking assistance modules
- Seat position and adjustment controllers
- Fluid level monitoring applications
Procurement Notes
Verify the specific suffix 'IQR' against official documentation to confirm package type and temperature range variations. Confirm end-of-life status as the C8051F54x series is marked Not Recommended for New Designs. Ensure compatibility with existing design constraints before procurement.
Selection Notes
Select this component when a small form factor MCU with integrated analog peripherals is required for automotive or industrial environments. Consider the 32-pin QFN/QFP package availability and verify pinout compatibility with other members of the C8051F54x family if migration is planned.
Part Context
The C8051F541-IQR belongs to the C8051F54x family of highly integrated mixed-signal microcontrollers. This family provides standalone system-on-a-chip solutions with on-chip voltage regulators, power-on resets, and watchdog timers. The devices are designed for applications requiring significant performance and integration within constrained physical spaces.
Replacement Considerations
Silicon Labs recommends EFM8BB52F16I-QFN20 as a replacement for the C8051F543-IM, which shares similar automotive qualifications and package types within the C8051F54x family context.
