PALF2080 | VPC3+CLF3 PROFIBUS I/O ASIC

PROFIBUS DP-V1/-V2 I/O ASIC

General Description

The VPC3+C from profichip® is a communication chip with 8-Bit Microprocessor interface for intelligent PROFIBUS I/O applications. Easily replace the Siemens SPC3 Slave Controller and experience even more features.

The VPC3+C handles message and address identification, checks the data security sequences and protocol processes for PROFIBUS-DP. It supports acyclic communication and alarm messages, described in the DP-V1 extension. Features described in the DP-V2 extension, as slave-to-slave communication Data eXchange Broadcast (DXB), clock synchronization and the Isochronous Mode (IsoM), are also provided.

Operation

Automatic baudrate recognition and support of data transmission rates up to 12 Mbit/s, the complete PROFIBUS-DP protocol integration, 4 kByte communication RAM and flexible processor interfaces are features to create state-of-the-art PROFIBUS I/O applications. The device may be operated with either 3.3V or 5V single supply voltages.

Compatibility

The VPC3+C is pin-compatible to the Siemens SPC3, making it suitable for direct replacement in already existing applications without restrictions or software modifications. Direct replacement for:
