2.1
PAN1321-SPP is supplied from a single supply voltage VSUPPLY. This supply voltage must always be present.
The PAN1321-SPP chip is supplied from an internally generated 2.5 V supply voltage. This voltage can be
accessed from the VREG pin. This voltage may not be used for supplying other components in the host system
but can be used for referencing the host interfaces.
The GPIO’s and the UART interface are supplied with dedicated, independent, reference levels via the VDD1 and
VDDUART pins. All other digital I/O pins are supplied internally by either 2.5 V (Internal2) or 1.5 V (Internal1).
Section 1.4
The I/O power domains (VDD1 and VDDUART) are completely separated from the other power domains and can
stay present also in low power modes.
2.2
PAN1321-SPP contains a crystal from which the internal 26 MHz system clock is generated. Also, the low power
mode clock of 32 kHz is generated internally, which means that no external clock is needed.
