Power:
3.3v supply pins are provided on either side of the module. These pins are all internally connected inside of the SiP
and are provided for convenience so that Ginseng can be powered from either the left or right sides to make
routing a PCB convenient for various applications. It is generally recommended to power the 3.3V bus from only
one side of the SiP. The pins on the other side should be shunted to ground through a 0.1uF and 1uF set of
capacitors.
XPD:
The XPD port is a SPI bus used for loading module firmware during development and mass production and also for
debugging. One of the following two styles of XPD port connectors should be included on all motherboard designs
that use Ginseng to ensure that loading code and debugging can be done easily. The XPD port interfaces to the
XPD module which provides an interface to a host computer via RS-232 or USB. The XPD port operates from the
V
CC
bus. To ensure proper functionality of the XPD interface, be sure to minimize the amount of capacitance on
the XPD lines. Note: the XPD_RESET / EXT_RST pin is tolerant up to 1.8V
MAX
-- if control of the Reset pin is
desired, a series diode must be used to guarantee the input voltage does not exceed the 1.8V max.

Customers can purchase an XPD Programming Module and ribbon cables from Eleven Engineering, or build their
own based on the Schematic, BOM, Assembly Drawing, and Gerber files, which are all available from Eleven without
charge. The XDE download program is also available from Eleven’s website without charge.
Digital IO:
Ginseng has general purpose digital IO (“GPIO”) pins available for use by the application firmware. GPIO pins use
the same logic voltage as the 3.3V pin and have the following software configurable features: IO direction, drive
strength (for output only), Schmitt Trigger (for input only), pull up (input only), pull down (input only), slew rate
(output only). Ginseng is also capable of active-high and active-low configuration of LEDs.
