Pin Descriptions
This section contains the pin diagram and descriptions for the VSC055-01 device.
Pin Diagram
The VSC055-01 has 100 pins. All pins have been placed to optimize their connection to external
components. Power and ground distribution is also optimized for core and high current I/O connections.
All high current I/O pins, serial interface pins, and the interrupt output are 5-V tolerant. Connect V
