8 / 20 page 8 LED Lighting Solutions Design Guide www.microchip.com/lighting LED Lighting Solutions 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: ■ Shunt Voltage Regulator ■ Comparators ■ Op Amps ■ ADC ■ Voltage Reference ■ Hardware PWM (Digital Timebase or SR Latch) 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 VDD 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.
