​C8051F0x/51x Automotive & Industrial MCUs

The C8051F50x/51x automotive and industrial Microcontrollers are available in small form factor packages from 32-pin to 48-pin. This makes these MCUs ideal for applications that need to pack a significant amount of performance (50 MIPS) and integration (12-bit ADC) into a constrained space. Pin-for-pin compatibility exists between the C8051F50x/51x series and the C8051F58x/59x series, the C8051F55x/56x/57x series and the C8051F54x series.
With on-chip Voltage Regulator, Power-On Reset, VDD monitor, Watchdog Timer and clock oscillator, the Automotive Microcontrollers, including the C8051F50x/1x devices, are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.

Technologies

  • Dedicated LIN hardware (both master and slave; V 1.2 and V 2.1 compatible)
  • Ultra-precision oscillator (±0.5%)
The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging without occupying package pins.
These automotive microcontrollers are specified for 1.8 to 5.25 V operation over the automotive temperature range (–40 to +125 °C). The Port I/O and RST pins are 5 V push-pull tolerant of input signals up to 5 V. The C8051F500/1/4/5 (-A and -I) devices are available in 48-pin QFP and QFN packages and the C8051F502/3/6/7 (-A and -I) devices are available in 32-pin QFP and QFN packages. All automotive microcontroller package options are lead-free, RoHS compliant and qualified to AEC-Q100.
