Using the enCoRe II Internal 3.3 Volt Regulator Output (VREG)
The enCoRe II has a built-in 3.3-volt regulator that can be used to supply external devices with
regulated voltage. To use the regulator for external devices, a 1.0uF or larger ceramic cap
must be loaded close to the output pin. For 40-pin devices, load the capacitor on position C2.
For 24-pin devices load the capacitor on position C9. The capacitor footprints on the board at
C2 and C9 are 0805 sized surface mount footprints. In addition there is a larger footprint
available to add a tantalum or electrolytic capacitor at C1 if more capacitance is desired for
larger transients, although the ceramic capacitor must still be used at C2 or C9 even if C1 is
loaded. Note that these capacitors must not be loaded if using the VREG pin (P1.2) on
enCoRe II as a GPIO. Be sure that the external circuitry does not consume more power than
the enCoRe II VREG output can provide as specified in the data sheet. Note that some
enCoRe II devices and all Wireless enCoRe II devices do not have an internal 3.3v regulator.
Wireless enCoRe II Development using the Applications Board
The Applications board provides a useful platform for Wireless enCoRe II development. The
following is a list of items to keep in mind when using the Applications board for Wireless
enCoRe II development.
In-circuit Programming on the Applications Board
enCoRe II devices and Wireless enCoRe II devices can be programmed while on the
Applications board using the ICE-Cube. Follow the programming steps below:
• External power can be easily connected to the board using the Vcc and GND headers.
• The Wireless enCoRe II Pod must be used for emulation with voltages below 4 volts.
• The prototyping area of the board can be used to attach radio modules or other
• Be aware of voltage restraints when using in-circuit programming. The ICE-Cube
