Cypress Semiconductor Corp. has announced an expansion of its automotive portfolio that will help enable manufacturers to bring high tech automotive systems historically available only in luxury models to mainstream vehicles. Leveraging a wide range of differentiated products that includes microcontrollers (MCUs), power management ICs (PMICs), memories and touch-sensing solutions, the portfolio enables value-added systems for Cypress’s top tier automotive customers.
As a key part of the expansion, Cypress introduced the first series of its Traveo microcontroller (MCU) family on the 40nm process technology node, which enables higher performance and more cost-efficient implementations of instrument clusters and body electronics. The series features up to 4MB of high-density embedded flash, stepper motor control, thin-film transistor (TFT) display control, advanced sound output capabilities and support for all in-vehicle networking standards required today for instrument clusters. In addition, a new MCU in the series is optimized for high-end body and gateway systems. 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. More information on the Traveo MCU family is available at http://www.cypress.com/traveo.
Additionally, Cypress introduced a transceiver for the Clock Extension Peripheral Interface (CXPI) designed to succeed the widely-used Local Interconnect Network (LIN) automotive communication protocol. CXPI helps reduce the bill of material and lower fuel consumption by requiring fewer wires and lighter wires in a vehicle. Cypress is 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. The series is based on the ARMCortex-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 up to 4MB of internal flash for application storage, enhanced secure hardware extension (eSHE) for robust security, and the industry-leading HyperBus interface that enables seamless connections with HyperFlash and HyperRAM memories.
Additionally, the Traveo S6J331X/S6J332X/S6J333X/S6J334X series includes a 16-bit Audio-DAC, a multi-channel mixer and I2S interfaces to output the complex, high-quality sounds required in today’s instrument clusters, supports Ethernet AVB for increased bandwidth in multimedia application and reduced programming time. It also combines with Cypress’s recently introduced 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 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. S6J335X supports wide ambient temperature of -40 degrees C to +125 degrees C.
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 20kbps. The transceiver also has a sleep/wake up control function for low noise and low power dissipation, enabling reliable and energy-efficient systems.
