The DPSI5 is a hardware implementation of a controller for the Peripheral Sensor Interface (PSI5) protocol.

Contact Provider Request Datasheet

Overview

The DPSI5 is a hardware implementation of a controller for the Peripheral Sensor Interface (PSI5) protocol. This controller complies with the PSI5 protocol specification V2.3 and is designed for use in electronic control units (ECUs) to ensure communication with up to six sensors.

Data transmission from the sensor to the ECU is achieved through current modulation on the power supply line, with a data rate of 125 kbit/s or 189 kbit/s, using a Manchester decoder. Data transmission from the ECU to the sensor is performed via voltage modulation on the power supply.

The DPSI5 supports operation in asynchronous or synchronous mode and accommodates a wide range of sensor data word lengths (8 to 28 bits). It also provides message verification using either a CRC checksum or bit parity.

Key features

  • Supports bidirectional communication between ECU-to-sensor
  • Asynchronous or synchronous operation
  • Manchester decoder digital data transmission
  • Data transmission speed 125Kbit/s or 189 Kbit/s
  • Support up to 6 time slots between SYNC pulses
  • Configurable data word length from 8 to 28 bits
  • Configurable type of frame checking each slot
  • CRC or parity checking
  • 24 bits time stamp
  • Configurable RX FIFO
  • Fully synthesizable
  • Static synchronous design with positive edge clocking and synchronous reset
  • Scan test ready
  • Available system interface wrappers:
    • AMBA – APB / AHB / AXI Lite Bus
    • Altera Avalon Bus
    • Xilinx OPB Bus

Benefits

  • Comprehensive PSI5 Support: Fully compliant with the PSI5 standard, ensuring seamless integration with existing and future sensor systems.
  • High-Speed & Reliable Communication: Optimized for real-time data transfer with minimal latency and maximum reliability.
  • Flexible Configuration: Supports multiple communication modes and can be easily adapted to specific project requirements.
  • Low Power Consumption: Designed for energy-efficient applications, making it ideal for automotive and industrial environments.

Functional Safety in Road Vehicles

Complexity of modern cars is growing rapidly without a doubt. A lot has happened since Ford T and the times when car was just a “fully mechanical” experience. Last few decades prove that safety is crucial. There’s no wonder then, that the safety ecosystem based on proprietary certification is a must. But even the best engineer is not capable of taking care of every single design detail. Everyone makes mistakes.

From Classical CAN and CAN FD to CAN XL: Functional Safety and Security for Next-Generation In-Vehicle Communication

This article reviews the functional-safety attributes of Classical CAN and CAN FD, then explains how CAN XL preserves and extends them. It also discusses higher-layer safety protocols, fault-tolerant CAN XL controller implementations, and CANsec, the CAN XL security extension inspired by the MACsec model. Finally, it highlights how the CAST CAN XL controller IP and CANsec acceleration IP can support the efficient deployment of safety- and security-capable in-vehicle networks.

JESD204 Frame Mapping explained from converter samples to lanes

The JESD204 Transport Layer oversees converter data mapping onto a set of JESD204 Lanes. The nature of these lanes is dependent on the version of the JESD204 standard and a function of the PCS and over the years despite the Serdes technology changing with ever increasing line rates, the function and features of the Transport Layer remained the same

Integrating PQC into StrongSwan: ML-KEM integration for IPsec/IKEv2

Integrating PQC into a widely deployed IKEv2 implementation is an important step toward making secure communication future-proof. We integrated ML-KEM, the NIST-standardized module-lattice KEM, into StrongSwan’s IKEv2 stack using our own KiviPQC-KEM hardware accelerator.
