SUNNYVALE, Calif., June 25, 2014 /PRNewswire/ -- Spansion Inc. (NYSE: CODE), a global leader in embedded systems, started shipping samples of its Spansion® Traveo™ automotive microcontroller S6J3100 series incorporating the high-performance CAN FD interface for enhanced in-vehicle networking. The new offering in the product family is focused on various automotive applications including body control module (BCM), heating, ventilation and air conditioning (HVAC).

Bosch invented the CAN standard many years ago and since then worked to improve in-vehicle communication through innovative solutions. Bosch introduced CAN FD as a seamless upgrade of the classic CAN technology the first time at the International CAN Conference in 2012. Like classic CAN, CAN FD enables highly reliable vehicle control, taking advantage of higher data rates with only a small impact on current software and applications. Spansion has started to supply leadership MCU products equipped with CAN FD.

"This announcement underscores our commitment to technology leadership in our Spansion Traveo family of automotive microcontrollers," said Nobuhiko Akasaka, vice president of Spansion's Automotive MCU Business Unit. "The delivery of the CAN FD interface in our MCUs provides industry-leading performance. This latest edition of the Traveo family builds upon our momentum in automotive microcontrollers and addresses customer requirements for faster, secure and energy-efficient solutions."

In addition to the CAN FD interface operating at 5Mbps, the S6J3110 series comes with a maximum 4MB of flash memory to enable high-level program control, and uses 55nm technology.  It also features Secure Hardware Extension (SHE) for network security and improved performance for connected cars, as well as advanced partial wakeup for lowering power consumption.

The Spansion Traveo family of microcontrollers is based on the ARM® Cortex®-R5 core and tailored for a broad range of automotive applications. In May 2014, Spansion introduced the first product of the family, the MB9D560 series for vehicle electrification utilized in hybrid electric vehicles (HEV) and electrical vehicles (EV).

Features of the Spansion Traveo S6J3110 series

  • High-end 32-bit MCU for body control: Spansion leads the industry by integrating the microcontroller with the ARM® Cortex-R5 core and with Bosch's advanced vehicle-mounted network technology CAN FD (maximum 5Mbps: S6J3110 series).  It delivers high-speed vehicle communication while retaining compatibility with conventional CAN (maximum 1Mbps).
  • Equipped with optimal macro for body control: The microcontroller is embedded with Spansion's top-class high-capacity flash memory (4MB) as internal memory. This flash memory enables readout after one wait for access from the CPU. Furthermore, the 144MHz high-speed operation is possible using a single power supply. Efficient utilization of CPU performance realizes high-speed memory access and low-power consumption.
  • Security function: In addition to conventional Flash security, which protects data stored in the microcontroller, the S6J3110 series is equipped with SHE (specification ver 1.1). The key management housed within the microcontroller is separated using hardware and an authentication function. This prevents data modification, theft and invalid access to the vehicle network.
  • Partial wakeup: Normally, when A/D conversion is performed from the low power-consumption mode, the CPU is interrupted and the system returns to normal operation. Afterwards, it is necessary to start the A/D converter from the CPU. However, when using partial wakeup, power is cut to items other than the Real Time Clock (RTC). Then, once the RTC performs a specified count, the A/D converter is started and conversion begins without passing through the CPU. If conversion results are not within the scope of set values, it is possible to start the CPU through interruption. Partial wakeup makes it possible to lower power consumption even further when periodically checking for sensor malfunctions.
