VRS51L3074 Peripheral and I/O Access and Development Board Prototyping Area
The development board includes a set of probe points that surround the VRS51L3074. These probe points provide a
direct connection to the device pins for signal probing.
Access to the device I/Os is also possible through two header footprints organized as follows:
The H17 header footprint provides access to the VRS51L3074 pins. Pin assignment on Header H17 directly corresponds
to the VRS51L3074 pin-out.
If the VRS51L3174 is installed on the PCB, Header H16 provides a direct connection to the 44-pin device and the H16
Header pin assignment directly corresponds to the device pin-out.
