Silicon Laboratories Introduces Highly Integrated MCU for Automotive Electronics
Silicon Laboratories Inc. announced its highly-integrated MCU family designed specifically for automotive electronics. By offering high functional density, the C8051F52/3x family of MCUs is intended to provide customers cost-effective and easy-to-use solutions for designing body electronics and other point-of-control applications including power windows, doors, sunroofs, trunks, seat positioning and mirrors.
The C8051F52x MCU family is claimed to be the first to combine a +/-0.5% integrated precision internal oscillator with 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 ten 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. This highly-integrated architecture enables automotive electronics designers to simplify the design process and reduce bill of materials.
The C8051F52/3x MCU family is intended to provide 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 watch-dog timer reset, helping designers to create reliable and durable electronics systems. In addition, Silicon Laboratories' patented MCU technology has been field tested and optimized for rigorous automotive specifications and maintains full performance over the complete automotive temperature range (-40 to +125°C).
Silicon Laboratories provides robust tools to support the C8051F52/3x MCU family, offering a fully integrated development environment that interfaces to the on-chip debug module via a USB to serial debug adapter. A device-specific development kit (C8051F530DK) is also available to facilitate software and application development. Samples of the C8051F52/3x MCU family are available now with fully AEC-Q100 qualified production in the second quarter of 2007. Silicon Laboratories' fabrication and assembly sites are ISO/TS16949 certified. Pricing for the C8051F530 begins at $1.79 and the C8051F520 begins at $1.49 in quantities of 10,000.
