Cypress grows automotive MCU family, offers complete dashboard silicon

January 13, 2016 // By Graham Prophet
Cypress Semiconductor has added to its automotive portfolio with products that it says will help enable manufacturers to bring high tech automotive systems previously available only in luxury models to mainstream vehicles.

The company aims to be a “one-stop” supplier to the sector. As part of the expansion, Cypress introduced the first series of its Traveo microcontroller family on the 40nm process technology node, which enables higher performance and more cost-efficient implementations of instrument clusters. The series features up to 4 MB 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. A new MCU in the series is optimised 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.

Cypress has also 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 helps reduce bill-of-material costs and lower fuel consumption by requiring fewer wire harnesses in a vehicle.

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 4 MB of internal flash for application storage, enhanced secure hardware extension (eSHE) for robust security, and the HyperBus interface that enables seamless connections with HyperFlash and HyperRAM memories.

The Traveo S6J331X/S6J332X/S6J333X/S6J334X series: includes a 16-bit audio-DAC, a multi-channel mixer and I ²S interfaces; supports Ethernet AVB for increased bandwidth in multimedia application and reduced programming time; and operates with Cypress’ S6BP50x series of automotive PMICs to provide a seamless solution for instrument clusters.

The new 40nm Traveo S6J335X series provides automotive manufacturers with the high performance of the other series, along
