PIC12F609/HV609, PIC12F615/HV615, PIC16F610/HV610 and PIC16F616/HV616 8-bit PIC® Microcontrollers with High Voltage Support and Fan Control Capabilities Summary Designing the simplest solution to a complex problem such as fan/motor control on a system board can often be challenging. Microchip has simplified both the design and implementation of such applications by introducing the new PIC12F609/HV609, PIC12F615/HV615, PIC16F610/HV610 and PIC16F616/ HV616. The first PIC microcontrollers of their kind, the 14-pin PIC16F616 provide an increased feature set inclusive of an enhanced full bridge Enhanced Capture/Compare Pulse Width Modulation (ECCP), eight 10-bit ADC channels, 2 comparators with selectable hysteresis, 4/8 MHz internal oscillator and 2K words of Flash program memory. The 8-pin PIC12F615, provides a half bridge ECCP, four 10-bit ADC channels, 1 comparator with selectable hysteresis, 4/8 MHz internal oscillator and 1K words of Flash program memory. The simplified PIC16F610 and PIC12F609 provide similar features without the ADC and ECCP. All of these PIC microcontrollers are available with high voltage variants and provide an integrated shunt voltage regulator allowing high voltage VDD support. The PIC12HV609, PIC12HV615, PIC16HV610 and PIC16HV616 provide the ability to run as low as 2.0V, up to an unspecified user-defined maximum voltage. The shunt regulator is active when the external VDD input is greater than 5V and disabled otherwise. These high voltage variations are ideal for cost sensitive applications with high voltage power rails. As with most PIC microcontrollers, the PIC12F609, PIC12F615, PIC16F610, PIC16F616, and High Voltage variants PIC12HV609, PIC12HV615, PIC16HV610 and PIC16HV616, can easily be utilized in a wide array of general purpose applications. Additional unique features make them particularly well suited for focused applications such as motor or fan control. The comparator on all variants is steerable and designed with greater hysteresis to provide the ability to use a Hall Effect element for speed monitoring of a fan or motor. Due to the differential signaling of the Hall Effect element, traditional comparators do not always provide the ability to accurately translate the varying frequency of the Hall Effect element into a manageable digital signal. With the addition of hysteresis, these newly designed comparators will in effect provide a trigger window and ultimately greater ease in such translations. This, paired with the integrated PWM, makes these products a robust fan-control solution that is more cost effective and flexible than traditional dedicated fan control methods.
