Cypress grows automotive MCU family, offers complete dashboard silicon
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 I²S 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 with support for EthernetAVB and a maximum of eight channels for CAN-FD, enabling automotive network gateways. It includes up to 12 channels of Multi-Function Serial (MFS), up to 64 channels of 12-bit ADC inputs, and up to 64 channels of base timers, including PWMs.
The S6BT11X CXPI transceiver series works as the interface between the CXPI datalink controller and the BUS line. S6BT11X can be used to enable ECU communication with speeds going up to approximately 20 kbps. The transceiver also has a sleep/wake up control function for low power dissipation, making it reliable and energy efficient.
