mrf24j40mc ds75002a-page 8 preliminary ? 2011 microchip technology inc. 1.3 operation the mrf24j40mc module is based on the microchip technology mrf24j40 2.4 ghz ieee 802.15.4 rf transceiver ic. serial communication and configuration are documented in the mrf24j40 data sheet (ds39776). this section emphasizes operational settings that are unique to the mrf24j40mc module design that must be followed for proper operation. 1.3.1 pa/lna control operation of the pa u3 and lna u2 is controlled by the mrf24j40 internal rf state machine through rf switches, u1 and u4, and the gpio1 and gpio2 pins on the mrf24j40. figure 1-5 shows the pa/lna block diagram. figure 2-2 is the schematic diagram for the module. the internal rf state machine is configured for the pa/ lna mode by setting testmode (0x22<2:0>) = 111 . pins gpio1 and gpio2 control the rf switches, pa and lna automatically when the mrf24j40 receives and transmits data. voltage regulator u5 supplies a regulated 2.2v to the pa. this provides a stable voltage to the pa over the v in voltage range of the module. u5 is enabled or shutdown from gpio3. ensure that the gpio3 direction has been set to output (trisgp3 (0x34<3>) = 1 ). setting a logic high (gpio3(0x33<3>) = 1 ) enables the voltage regulator and supplies voltage to the pa. setting a logic low (gpio3 (0x33<3>) = 0 ) will shutdown the voltage regulator, disabling the pa, and provides the lowest shutdown current. figure 1-5: pa/lna block diagram note: a complete explanation of the operation of the pa/lna control is documented in the mrf24j40 data sheet (ds39776), section 4.2 external pa/lna control. mrf24j40 gpio1 gpio2 u.fl connector balun rfp rfn pa upg2250t5n lna pa rf switch upg2179tb rf switch upg2179tb lna upc8233tk v2 v1 v2 v1 gpio3 voltage regulator tc1187vct713 v out shdn 50 ohm downloaded from: http:///
? 2011 microchip technology inc. preliminary ds75002a-page 9 mrf24j40mc 1.3.2 energy detection (ed) before performing an energy detection (see section 3.6.1 rssi firmware request (rssi mode 1) in the mrf24j40 data sheet (ds39776)), perform the following steps: 1. configure the internal rf state machine to normal operation (testmode (0x22f<2:0>) = 000 ). 2. configure gpio2 and gpio1 direction for output (trisgp2 (0x34<2>) = 1 and trisgp1 (0x34<1>) = 1 ). 3. set gpio2 (0x33<2>) = 1 and gpio1 (0x32<1>) = 0 . this enables the lna and disables the pa. 4. perform the energy dete ction following the steps in section 3.6.1 rssi firmware request (rssi mode 1) in the mrf24j40 data sheet (ds39776). 1.3.3 sleep to get the lowest power consumption from the mrf24j40mc module during sleep, it is necessary to disable the pa, pa voltage regulator and lna. to do this, perform the following steps: 1. configure the internal rf state machine to normal operation (testmode (0x22f<2:0>) = 000 ). 2. configure the gpio3, gpio2 and gpio1 direction for output (trisgp3 (0x34<3>) = 1 , trisgp2 (0x34<2>) = 1 and trisgp1 (0x34<1>) = 1 ). 3. set gpio2 (0x33<2>) = 0 and gpio1 (0x32<1>) = 0 . this disables the lna and the pa. 4. set gpio3 (0x33<3>) = 0 . this shuts down the voltage regulator u5 that supplies 2.2 volts to the pa. 5. put the mrf24j40 to sleep following the steps in the mrf24j40 data sheet (ds39776). when waking the module, re-enable the pa/lna mode. note: the lna will amplify the received signal. the rssi value will include the receive signal strength plus the lna amplification. downloaded from: http:///
