Silicon Laboratories has announced what it claims is the industry’s smallest automotive communications controller. The C8051F50x family of mixed-signal MCUs integrates an ultra high-performance internal precision oscillator to support both CAN and LIN communication networks without an external crystal or resonator.
The C8051F50x family integrates a 50MIPS core, up to 64 KB of high-endurance Flash, four KB of RAM, 32-message buffer CAN 2.0B hardware controller and a hardware LIN 2.0 controller in a 5 x 5 mm package, providing customers with the memory and computational resources for realtime applications requiring CAN and LIN software stacks. The internal precision oscillator provides an accuracy of ±0,5% across the entire temperature (-40 to +125°C) and voltage (1,8 to 5,25 V) range.
Analog features include a 12-bit, 200 Ksps, 32-channel analog to digital converter (ADC), a precision voltage reference and a programmable comparator which can be dynamically re-mapped to different I/O pins during run-time. Additionally, the integrated temperature sensor provides an internal mechanism for diagnostics and system calibration.
