Automotive and Industrial Microcontrollers

Automotive and Industrial Microcontrollers

Silicon Labs Automotive/Industrial microcontrollers are auto-grade products qualified and tested to the AEC-Q100 specification with high temperature operation up to 125 °C. These industrial and automotive MCUs include a CAN 2.0B interface, LIN 2.1 interface, an integrated precision oscillator (±0.5%) that allows full spec operation without an external crystal oscillator, 1.8 to 5.25 V supply voltage and a 12-bit ADC. All automotive and industrial family MCU products are implemented in small form factor packages.

Highest Functional Density

These Industrial and Automotive mixed-signal microcontrollers combine a high-speed 8051 CPU, Flash memory, best-in-class analog peripherals and digital signal processing in ultra-small packages, enabling full operational specification across the entire automotive voltage and temperature range with no design trade-offs. These microcontrollers offer the highest functional density of any available 8-bit automotive microcontroller.

Hardware LIN 2.1 Controller

The LIN hardware implementation offers advantages over competing UART or software implementations. The dedicated message buffer and hardware generated flow control timing results in higher overall system bandwidth in our Industrial and Automotive microcontrollers. The standard register-based control interface simplifies communication software development and minimizes code size.

Ultra-Precision Oscillator (±0.5%)

With ±0.5% tolerance across temperature (–40 to 125 ºC) and voltage (1.8 to 5.25 V), these Industrial and Automotive microcontrollers offer a fully integrated LIN 2.1 master-mode implementation without any external timing components. The ultra-precision internal oscillator is configured to maximum instruction clock (25 MHz), resulting in no compromise between using an internal oscillator and achieving maximum CPU bandwidth.
