Summary
Building upon Microchip’s leadership in 8-bit
microcontrollers, the PIC16F72X Family (PIC16F707/
727/726/724/723A/722A/721/720) is a versatile,
general-purpose product line that enhances the usability
and features of any end-product while keeping costs low.
The PIC16F72X Family provides a general purpose approach
to bringing a higher level of intelligence and reliability into
various applications including; interactive toys or consumer
products such as electric tooth brushes and blenders. With
fl exible product options and low cost, PIC16F72X devices
allow for increased application functionality while minimizing
BOM costs.
The PIC16F72X Family has an operating voltage range
of 1.8V to 5.5V, with the low-power PIC16LF72X variants
offering lower standby and other power consumption
specifi cations from 1.8V to 3.6V. It features a 16 MHz
internal oscillator; up to 14 Analog-to-Digital Converter (ADC)
channels; communication interfaces (SPI, I
2
C™, AUSART)
and up to two Capture/Compare/PWM (CCP) modules;
plus the mTouch™ Capacitive Sensing Module peripherals
(28-40-pin MCUs only). These highly integrated devices are
well-suited for a wide range of general-purpose applications
in the appliance, industrial, consumer electronic and
many other markets. All variations feature a Timer1 Gate
that runs from the internal 16 MHz oscillator, providing
ease in conditional event counting and measurements.
With up to 14 ADC channels, up to two CCP modules and
communication peripherals, these PIC® microcontrollers
increase design fl exibility with the ability to interface with
external devices such as environmental sensors, as well as
provide additional system control and monitoring.
The addition of the integrated mTouch Capacitive Sensing
Module (28-40-pin MCUs only) allows customers to
further distinguish their products. The mTouch Sensing
Solution peripheral makes it easy to add proximity sensing
or capacitive touch-sensing user interfaces in place of
mechanical buttons or switches. Additionally, the mTouch
peripheral can operate while the device is in “Sleep mode”
with a total power consumption of <10μA, bringing further
power savings to the user. When designing applications
such as: cell phones, home appliances or thermostats –
mTouch technology provides an inexpensive, reliable and
aesthetically pleasing interface.
The 20-pin PIC16F720/721 adds the self read-write feature
to its program Flash memory. Self read-write Flash serves
as a low cost alternative to the Data EE; and is very useful
when applications require remote updates, or an application
needs to store system data or look-up tables.
