MICROCHIP PIC16F616

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.
