a. VDD_RF collectively refers to the VDDIF, VDDLNA, VDDPX, and VDDRF RF power supplies.
b. If VDDO is not applied, voltage should never be applied to any digital I/O pins (I/O pins should never be driven or pulled high). The list of digital I/O pins includes the
following (these pins are listed in Section 7.: “Pin Information,” on page 25 with VDDO shown as their power domain):
GPIO[3], GPIO[5], GPIO[6]
SCL, SDA
N_MODE
SPIM_CS_N, SPIM_CLK

a. VDD_RF collectively refers to the VDDIF, VDDLNA, VDDPX, VDDLNA, VDDRF RF power supplies.
b. Overall performance defined using integrated regulation.
c. VDDTF for Class 2 must be connected to VREG (main LDO output). VDDTF for Class 1 must be connected to VREGHV (HV LDO output) or an external voltage source.
Refer to the Cypress compatibility guide for configuration details. VDDTF requires a capacitor to ground. The value of the capacitor must be tuned to ensure optimal
RF RX sensitivity. The typical capacitor value is 10 pF for both packages. The value may depend on board layout.
