C8051F52x and C8051F53x Automotive Microcontroller Family from Silicon Laboratories

Silicon Laboratories announced the C8051F52/3x family targeted for automotive electronics applications. The C8051F52x MCU family has integrated precision internal oscillator, 8K Flash, 25 MIPS, 12-bit ADC, dedicated LIN 2.0 controller, 16-bit timers/PWM, SPI, UART, and six I/O lines in a small 3 x 3 mm QFN package. The C8051F53x MCU family has the same feature set but adds 10 additional I/O lines and is offered in 20-pin QFN and TSSOP packages. Both families integrate additional analog features such as programmable comparators, voltage regulators, and on-board temperature sensors to further reduce design complexity.

The C8051F52/3x MCU family provides automotive electronics applications with greater functionality, sensing and control. For example, the integrated LIN 2.0 controller combined with the ultra-high-precision internal oscillator enables designers to implement LIN master-mode communication networks without the need for external timing components, further reducing overall system cost. The C8051F52/3x MCU family also includes power-on-reset, brown-out protection, and a watchdog timer reset, helping designers to create reliable and durable electronics systems.

Samples of the C8051F52/3x MCU family are available now with fully AEC-Q100 qualified production in the second quarter of 2007. Pricing for the C8051F530 begins at $1.79 and the C8051F520 begins at $1.49, each in quantities of 10,000.
