The CSENT core implements a controller for the Single Edge Nibble Transmission (SENT) protocol. It complies with the SAE J2716 standard and also the industry de-facto standard Short PWM Code (SPC) protocol, and can be used for conveying data from one or multiple sensors to a centralized controller using a single SENT line. The CSENT core can be configured as a Transmitter and/or as a Receiver, and therefore it is suitable for adding a SENT interface to devices transmitting sensor data or to controllers receiving sensor data. It provides access to its control, status, and data registers via a 32-bit APB bus interface, and a comprehensive set of interrupt signals facilitates interrupt-based operation. The core allows for Transmitter operation without requiring any external programming or control. The reset values for all its control registers are defined at synthesis time, and at run time the system only needs to write sensor data to the core.
The CSENT core can be mapped to any Intel FPGA device (provided sufficient silicon resources are available) and optimized to suit the particular project’s requirements. The core occupies approximately 700 ALMs, under its full configuration, and about 280 ALMs when configured as transmitter-only. Please contact CAST to discuss resource utilization and performance for your application and target device.
