Pin Connections

This section describes the electrical connections for the various pins on a Series 6000 chip.

Unless specified otherwise, the connections apply to both the FT 6000 Smart Transceiver and

the Neuron 6000 Processor.
See Appendix E, Example Schematic, for a more complete example schematic for an FT 6000

Smart Transceiver.
Connect the VDD3V3 pins (8, 18, 29, 30, 41, and 42) to V

DD33

. Also connect the AVDD3V3

pin (31) to an analog V

DD33

source, if different from the digital V

DD33

source. In general, the

VDD3V3 pins and the AVDD3V3 pin connect to the same V

DD33

source. In addition, connect

decoupling capacitors to the VDD3V3 pins, as shown in Figure 10.
