The VPC3+CLF product is at EOL with last time buy 4Q18: Product Change Notice.

VPC3+C is a communication chip with 8 Bit Microprocessor interface for intelligent PROFIBUS slave applications. The VPC3+C is Pin, function and software compatible with Siemens SPC3, 6ES7-195-0BD04-0XA0.

The VPC3+C handles the message and address identification, the data security sequences and the protocol processing for PROFIBUS-DP. In addition the acyclic communication and alarm messages, described in DPV1 extension, are supported. Furthermore the slave-to-slave communication Data exchange Broadcast (DXB) and the Isochronous Mode (IsoM), described in DPV2 extension, are also provided.

Automatic recognition and support of data transmission rates up to 12 Mbit/s, the integration of the complete PROFIBUS-DP protocol, 4 Kbytes communication RAM and the configurable processor interface are features to create high-performance PROFIBUS slave applications. The device can be operated with either 3.3V or 5V single supply voltage. For 3.3V operation the inputs are 5V tolerant.

There are two versions available, the VPC3+CLF (PALF2030, formerly PALF2003), and the VPC3+CLF3 (PALF2080 Formerly PALF2008). The VPC3+CLF3 adds DP-V2 clock synchronization, and uses 20% less current than the VPC3+CLF.
