FIGURE C-1: PICDEM™ Z MRF24J40 2.4 GHZ DAUGHTER CARD

C.3 SCHEMATIC

The PICDEM Z MRF24J40 2.4 GHz Daughter Card schematic is shown in Figure C-2.

Note: The MRF24J40 SDO pin 17 defaults to a low state when nCS is high (the

MRF24J40 is not selected). If the MRF24J40 Daughter Card is to share an

SPI bus, a tri-state buffer can be placed on the SDO signal to provide a

high-impedance signal to the SPI bus. Refer to the “MRF24J40 Data Sheet”

(DS39776) for more information.
