Connecting 5V circuitry to WirelessUSB
PSoC and related analog design will be 5V but wireless-USB is 3.3V. What is recommended way to connect them?
The preferred method is to implement a current limiting series resistor that limits the current to less than 1mA.
General note: Typically, these pins are nRESET, nPD, IRQ, nSS, SCK, MOSI, and MISO.
