<b>PALF2012</b> | VPC3+S (QFP48) PROFIBUS I/O ASIC

PROFIBUS-DP V1/V2 I/O Controller with serial interface. SPC3 and DPC31 compatible. General Description profichip's VPC3+S is a communication chip with 8-Bit parallel, SPI or I2C Microprocessor interface for intelligent PROFIBUS I/O applications. The VPC3+S 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 DP-V1 extension, are supported. Furthermore the I/O-to-I/O communication Data eXchange Broadcast (DXB) and the Isochronous Mode (IsoM), described in DP-V2 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 KByte communication RAM and the flexible processor interface are features to create state-of-the-art PROFIBUS I/O applications. Features: SPI, I2C, parallel-interface LQFP48 (9x9mm) package 4kByte communication RAM Function and s
