Hardware Description
General Device Overview
The UART interface is used for communication between the host and PAN1322-SPP. The lines UARTTXD and
UARTRXD are used for commands, events and data. The lines UARTRTS and UARTCTS are used for hardware
flow control.
Low power mode control of PAN1322-SPP and the host can be implemented in by using the pins P0.14 and P0.0.
P0.14 is used by the host to allow PAN1322-SPP to enter low power mode and P0.0 is used by PAN1322-SPP to
wake-up the host when attention is required. Additionally, the host could hardware reset PAN1322-SPP using the
RESET# pin.
Power is supplied to a single VSUPPLY input from which internal regulators can generate all required voltages.
The UART and the GPIO’s interfaces have separate supply voltages so that they can comply with host signaling.
