Introduction
The enCoRe II LV family brings the features and benefits of the
enCoRe II to non-USB applications. The enCoRe II family has
an integrated oscillator that eliminates the external crystal or
resonator, reducing overall cost. Other external components,
such as wake-up circuitry, are also integrated into this chip.
The enCoRe II LV is a low-voltage, low-cost 8-bit Flash-
programmable microcontroller
The enCoRe II LV features up to 36 general-purpose I/O
(GPIO) pins. The I/O pins are grouped into five ports (Port 0 to
4). The pins on Port 0 and Port 1 may each be configured
individually while the pins on Ports 2, 3, and 4 may only be
configured as a group. Each GPIO port supports high-
impedance inputs, configurable pull up, open drain output,
CMOS/TTL inputs, and CMOS output with up to five pins that
support programmable drive strength of up to 50 mA sink
current. Additionally, each I/O pin can be used to generate a
GPIO interrupt to the microcontroller. Each GPIO port has its
own GPIO interrupt vector with the exception of GPIO Port 0.
GPIO Port 0 has in addition to the port interrupt vector, three
dedicated pins that have independent interrupt vectors
(P0.2âP0.4).
