Microcontrollers reduce automotive ECU count

Freescale Semiconductor has expanded its Qorivva and S12 MagniV vehicle-body-network microcontroller series with devices that integrate connectivity, functional safety, security, and network management, trimming both the number of required ECUs and associated heavy copper wiring in automobiles. The level of integration these MCUs provide can help simplify vehicle network design and reduce vehicle weight.
A single-chip solution for central body control and gateway applications, the Qorivva MPC5748G provides a diverse set of networking communications peripherals, with support for Ethernet with AVB (Audio Video Bridging), FlexRay, MLB (Media Local Bus), USB, CAN FD (Flexible Data Rate), and up to 18 LIN controllers.

Automotive OEMs can increase the intelligence of CAN termination nodes and LIN nodes with the S12 MagniV S12ZVC and S12ZVL MCUs. These devices allow designers to achieve the smallest possible CAN terminal nodes (using the S12ZVC) and LIN nodes (using the S12ZVL) and help reduce pc board size by as much as 30%.

All three microcontrollers are included in Freescale’s SafeAssure functional safety program, designed and developed to address the ISO 26262 standard. Limited samples of the MPC5748G and S12ZVL are expected to be available in the second quarter of 2013. Limited samples of the S12ZVC are expected to be available in the third quarter of 2013. General market availability is anticipated in the second half of 2014.
