MRF24WG0MA_12 Datasheet, PDF (11/38 Pages) Microchip Technology – MRF24WG0MA/MB Data Sheet 2.4 GHz IEEE 802.11b/g™

2.0 CIRCUIT DESCRIPTION
The MRF24WG0MA/MB interfaces to Microchip PIC18, PIC24, dsPIC33, and
PIC32 microprocessors with a minimal of external components through digital-
only connections. This section details use of the module, starting with an
example host connection as shown in Figure 2-1.
