10 / 70 page MC13211/212/213 Technical Data, Rev. 1.8 10 Freescale Semiconductor 19 PTC7 Digital Input/Output MCU Port C Bit 7 20 PTE0/TXD1 Digital Input/Output MCU Port E Bit 0 / SCI1 TX data out 21 PTE1/RXD1 Digital Input/Output MCU Port E Bit 1/ SCI1 RX data in 22 VDDD Power Output Modem regulated output supply voltage Decouple to ground. 23 VDDINT Power Input Modem digital interface supply 2.0 to 3.4 V. Decouple to ground. Connect to Battery. 24 GPIO51 Digital Input/Output General Purpose Input/Output 5. See Footnote 1 25 GPIO61 Digital Input/Output Modem General Purpose Input/Output 6 See Footnote 1 26 GPIO71 Digital Input/Output Modem General Purpose Input/Output 7 See Footnote 1 27 XTAL1 Input Modem crystal reference oscillator input Connect to 16 MHz crystal and load capacitor. 28 XTAL2 Input/Output Modem crystal reference oscillator output Connect to 16 MHz crystal and load capacitor. Do not load this pin by using it as a 16 MHz source. Measure 16 MHz output at CLKO, programmed for 16 MHz. 29 VDDLO2 Power Input Modem LO2 VDD supply Connect to VDDA externally. 30 VDDLO1 Power Input Modem LO1 VDD supply Connect to VDDA externally. 31 VDDVCO Power Output Modem VCO regulated supply bypass Decouple to ground. 32 VBATT Power Input Modem voltage regulators’ input Decouple to ground. Connect to Battery. 33 VDDA Power Output Modem analog regulated supply output Decouple to ground. Connect to directly VDDLO1 and VDDLO2 externally and to PAO_P and PAO_M through a bias network. 34 CT_Bias RF Control Output Modem bias voltage/control signal for RF external components When used with internal T/R switch, provides ground reference for RX and VDDA reference for TX. Can also be used as a control signal with external LNA, antenna switch, and/or PA (high level is VDDA). 35 RFIN_M RF Input (Output) Modem RF input/output negative When used with internal T/R switch, this is a bi-directional RF port for the internal LNA and PA 36 RFIN_P RF Input (Output) Modem RF input/output positive When used with internal T/R switch, this is a bi-directional RF port for the internal LNA and PA 37 NC Not used May be grounded or left open Table 2.
