Profichip's VPC3+S is a communication chip with 8-Bit parallel processor
interface for intelligent PROFIBUS DP-Slave applications. Alternatively an
SPI or I
The VPC3+S handles the message and address identification, the data
security sequences and the protocol processing for PROFIBUS DP. In ad-
dition the acyclic communication and alarm messages, described in DP-V1
extension, are supported. Furthermore the slave-to-slave communication
Data eXchange Broadcast (DXB) and the Isochronous Bus Mode (IsoM),
described in DP-V2 extension, are also provided. For high-precision syn-
chronized motion control applications the chip is equipped with an HW-PLL
for IsoM.
Automatic recognition and support of data transmissions rates up to 12
Mbit/s, the integration of the complete PROFIBUS DP protocol, 4K Byte
communication RAM and the configurable processor interface are features
to create high-performance PROFIBUS DP-Slave applications. The device
is to be operated with 3.3V single supply voltage. All inputs are 5V tolerant.
Profichip's VPC3+S is another member of profichip's successful VPC3+
family. It is software compatible to other VPC3+ series devices however it
offers some unique features like serial processor interfaces, IsoM-PLL and
a very small package.
As there are also simple devices in the automation engineering area, such
as switches or thermo elements, that do not require a microcontroller for
data preprocessing, profichip offers a DP-Slave ASIC with 32 direct in-
put/output bits. The VPCLS2 handles the entire data traffic independently.
No additional microprocessor or firmware is necessary. The VPCLS2 is
compatible to existing chips.
