Description
Pads supply (2.1 – 3.6V)
When using the SPI interface, this signal is left not connected.
UART Transmitted Data (from EM260 to Host)
SPI Host Interrupt signal (from EM260 to Host)
UART Received Data (from Host to EM260)
Programming and Debug Interface, Clock (internal pull down)
Programming and Debug Interface, Master In / Slave Out
Programming and Debug Interface, Master Out / Slave In (external pull-down re-
quired to guarantee state in Deep Sleep Mode)
Programming and Debug Interface, load strobe (open collector with internal pull up)
Ground Supply
1.8V Flash memory supply; should be connected to VREG_OUT
Spare Debug signal
Link and Activity signal
SPI Wake Interrupt signal (from Host to EM260)
When using the UART interface, this signal is left not connected.
1.8V digital core supply; should be connected to VREG_OUT
1.8V synthesizer and prescalar supply; should be connected to VREG_OUT
24MHz crystal oscillator or left open for when using an external clock input on OSCA
24MHz crystal oscillator or external clock input
1.8V high-frequency oscillator supply; should be connected to VREG_OUT
Ground supply pad in the bottom center of the package forms Pin 41 (see the EM260
Reference Design for PCB considerations)
