Connecting Three-Wire EEPROMs
μWire EEPROMs and other compatible devices should be connected to the DIO pins DIO4 and DIO5, as shown in
Figure 36. DIO5 connects to both the DI and DO pins of the three-wire device. The CS pin must be connected to a
vacant DIO pin of the 71M6521DE/DH/FE. A pull-up resistor of roughly 10k ? to V3P3D (to ensure operation in
BROWNOUT mode) should be used for the DI/DO signals, and the CS pin should be pulled down with a resistor to
prevent that the three-wire device is selected on power-up, before the 71M6521DE/DH/FE can establish a stable
signal for CS. The DIO_EEX register in I/O RAM must be set to 10 in order to convert the DIO pins DIO4 and DIO5 to
MICROWIRE pins. The pull-up resistor for DIO5 may not be necessary.

The RX pin should be pulled down by a 10k ? resistor and additionally protected by a 100pF ceramic capacitor, as
shown in Figure 37.
