Cypress modernises Traveo MCU product line

January 12, 2016 // By Christoph Hammerschmidt
With a new generation of Traveo microcontrollers Cypress creates the basis for further innovation including over-the-air firmware updates. And by the way the company also pulls a successor for the venerable LIN bus out of the hat. The new chips enable automotive designers to transplant sophisticated features from high-end vehicles to more cost-efficient market segments.

As a key part of the expansion, Cypress introduces the first series of its Traveo microcontroller (MCU) family on the 40nm process technology node. This microcontroller family is based on the ARM Cortex R5 node. Originally developed by Fujitsu, the microcontrollers have been acquired later by Spansion which in turn was taken over by Cypress.

The 40nm implementation enables higher performance and more cost-efficient implementations of instrument clusters, a market segment where in the past years Nvidia evolved as a strong comtender. The 40-nm Traveo series features up to 4MB of high-density embedded flash, meter control, small thin-film transistor (TFT) display control, advanced sound output capabilities and support for many kinds of networking standards for a wide variety of instrument clusters. In addition, a new MCU in the series is optimized for high-end body and gateway control. The 40nm technology will also provide the ability to embed more on-chip flash memory for advanced applications. The 40nm Traveo MCUs will make it easier to implement Firmware Over-The-Air (FOTA) updates, which enable consumers to get new software fixes and features and new applications for their vehicles on-the-go.

Additionally, Cypress introduced a transceiver for the low-speed Clock Extension Peripheral Interface (CXPI) designed to succeed the widely-used Local Interconnect Network (LIN) automotive communication protocol. CXPI is said to help reduce bill-of-material costs and lower fuel consumption by requiring fewer wire harnesses in a vehicle. Cypress claims to be the only supplier to offer a CXPI transceiver and automotive MCUs, enabling a complete solution.

The new 40nm Traveo S6J331X/S6J332X/S6J333X/S6J334X series provides automotive manufacturers with a high-performance and cost-effective platform for classic instrument clusters with small thin-film transistor (TFT) displays. The series is based on the ARM Cortex-R5 processor with 240-MHz performance and supports the Controller Area Network-Flexible Data (CAN-FD) automotive communication protocol for increased data bandwidth for faster networking. The MCUs integrate 4MB of internal flash for application storage, enhanced secure hardware extension (eSHE) for
