CAN/CAN FD to CAN/CAN FD bridge

CANFDBridge, and CANFDBridge+ (domestic main control chips) are high - performance CAN(FD) intelligent protocol bridges developed by Guangzhou ZHIYUAN Electronics Co., Ltd. They integrate 2 switchable CAN(FD) interfaces.
CANBridge+ only supports the high - speed CAN standard, while CANFDBridge and CANFDBridge+ support both the ISO standard CAN FD and the Bosch CAN FD standard. Each interface is equipped with an independent 2500VDC electrical isolation protection circuit, which protects the interface card from damage caused by ground loop current and enhances the reliability of the system when used in harsh environments.

Build dreams with craftsmanship, and painstakingly research for a unique "core".

CANFDBridge+ inherits the powerful performance of CANFDBridge. The implantation of the ultra - high - performance RISC - V core microcontroller from domestic company HPMicro (Synwit Semiconductor) is like adding wings to a tiger, enabling the data transmission and processing capabilities to reach a new level.

Quickly connect CAN devices to CAN FD network

CANFDBridge CAN integrates traditional CAN bus network with CAN FD network through protocol conversion, and quickly upgrades the CAN device.

Restore data through flexible conversion combination

CANFDBridge and CANFDBridge+ achieve the mutual conversion between the 8-byte length of traditional CAN and the 64-byte length of CAN FD through three methods: direct conversion, merging, and splitting, restoring the original data without loss.

Support 64 groups of ID filtering to effectively filter unnecessary data

For both CANFDBridge and CANFDBridge+, each CAN FD channel supports the configuration of 64 sets of filtering rules for standard frame single ID / standard frame group ID / extended frame single ID / extended frame group ID. This effectively filters out unnecessary data and reduces the bus load (CANBridge+ supports ID filtering for CAN channels).

Support CAN ID and data transformation mapping

CANFDBridge and CANFDBridge+ supports the transformation mapping of ID and data and can transform and output the input message with specific ID and data so that the same device can network accessed. (CANBridge+ supports the ID - data mapping for CAN channels.)/p>

Flexible Baud rate sampling point with built-in terminal resistance enabled

CANFDBridge and CANFDBridge+ have built - in configurable termination resistors. Users can enable or remove them through software. They also come with a self - contained custom baud rate calculator, which can calculate the baud rate registers for TESG1, TSEG2, SJW, and sampling points that match the network, enhancing the adaptability of the device. (For CANBridge+, an external wire is required to enable the built - in resistor.)

Bus error feedback function improves fault early warning capability

CANFDBridge、CANFDBridge+ features an error message feedback function, enabling the local device to monitor the bus status on the other side and enhance fault warning capabilities.

Configure the interface to read the bus error status

Through the configuration interface of CANFDBridge and CANFDBridge+,the communication error status can be read, making it easier to identify the general direction of faults and troubleshoot software and hardware problems.

2500VDC electrical isolation CAN/CAN FD interface

2500VDC electrical isolation CAN/CAN FD interface and electrostatic level contact discharge of ±8KV help you effectively isolate interference.
