UM-B-036 DA14580 Antenna module for QFN48 package 4.7 Module GPIOs The QFN48 antenna module provides 32 general purpose input/output pins (including JTAG signals). The interfaces are multiplexed with the GPIOs and can be enabled by appropriate programming. The available GPIO functions are presented in Table 3.
UM-B-036 DA14580 Antenna module for QFN48 package 4.8 Power management The QFN48 antenna module is supplied by a single power supply via pin 27 (VBAT). The supply voltage of the module follows the specification of the DA14580 IC in buck configuration. The supply voltage ranges from 2.4 V to 3.6 V. Embedded in the DA14580, the DC/DC converter and LDOs produce all voltages required for the system operation. The DC/DC converter is supplied from VBAT through a bead (FB1) and produces 1.
UM-B-036 DA14580 Antenna module for QFN48 package 4.8.1 DC/DC converter in boost configuration Supplying the QFN48 antenna module at a lower voltage (down to 0.9 V) is feasible, but modification of the module’s components is needed. Please note that this configuration has not been used in the tests for the FCC/ETSI certification.
