Integrate Multiple Tasks –
PIC12 and PIC16 Mixed Signal Solutions
The LED current drive function can be integrated with other
tasks on the same MCU. Members of the PIC12F and PIC16F
device families provide the next step up from the PIC10F
family and facilitate highly integrated mixed signal designs in
8, 14 and 20-pin package options. The available peripherals
in this series of devices include:

These peripherals allow external power circuits to be directly
controlled by the MCU. For a LED driver application, the
analog peripherals can be configured and interconnected in
software to provide constant current regulation. This leaves
the CPU free to run other tasks such as communication,
dimming control or fault detection.
Internal 5V Regulator
The internal shunt voltage regulator option allows the MCU
to be operated from a higher voltage DC bus making it
useful in AC line powered applications. Only a series resistor
is required between the power supply and the device V
pin.
Devices with an “HV” designator in the part number have an
internal regulator.

Easy Migration
The 8, 14 and 20-pin devices in the PIC12F and PIC16F
families have compatible pin-outs for upward and downward
migration. Common connections such as power and ground
are located in the same positions on the package footprint
so that an 8-pin design can easily be expanded to a 14 or
20-pin design.
