PIC16(L)F19197 Product Family

Simplify the design of Low Power LCD Applications

The PIC16(L)F19197 product family is a line of eXtreme Low-Power (XLP) microcontrollers for driving Liquid Crystal Displays (LCD) that features Core Independent Peripherals and Intelligent Analog. The nine member family includes battery friendly LCD drive charge pump, 12-bit Analog-to-Digital Converter with Computation (ADC2), low-power comparator, and active clock tuning of its high frequency oscillator. These devices are an ideal solution for low-power and battery powered touch enabled LCD applications. The family consists for 28- to 64-pin devices with up to 56 KB of Flash and 4 KB of RAM.

LCD Enhancements

To support battery applications, the product features a charge pump that ensures LCD screens maintain consistent contrast even as battery voltage drops. High current I/O pins also provide the ability to directly drive LCD backlighting. Each of these features is offered along with the ability to drive up to 360 LCD segments.

Intelligent Analog

The 12-bit ADC2 automates signal acquisition and processing tasks making robust touch buttons and sliders easy to implement. Addition analog features include a Low Power Comparator, Zero Cross Detect (ZCD), and a 5-bit Digital-to-Analog converter (DAC).

Low Power Features

Power saving functions such as IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. IDLE Mode is a power saving mode that puts the CPU core to sleep while the internal peripherals continue to operate from the system clock and DOZE mode enables the CPU core to run at a slower speed compared to the system clock used by the internal peripherals. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption. Extended battery life is achieved with eXtreme Low-Power (XLP) technology.

Development Made Easy

The PIC16(L)F19197 family is supported by MPLAB® Code Configurator (MCC), a free software plug-in that provides a graphical interface to configure peripherals and functions specific to your application. MCC is incorporated into our award-winning development environments, the down-loadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE.

Building Blocks for Function Enablement

Analog-to-Digital Converter with Computation (ADC2)
The Analog-to-Digital Converter with Computation (ADC²) helps accelerate common math tasks normally done in software by offering modes like averaging, low-pass filter, oversampling and threshold comparison.

More Information
Zero Cross Detect (ZCD)

The Zero Cross Detect (ZCD) module can monitor AC line voltage, and indicate zero crossing activity. This information is made directly available to on-board waveform generation peripherals for use in TRIAC control applications, greatly reducing both CPU demand and BOM cost.

More Information
Complementary Waveform Generator (CWG)

Complementary Waveform Generator (CWG) provides a complementary waveform with rising and falling edge dead band control, enabling high efficiency synchronous switching, with no processor overhead. The CWG also incorporates auto shutdown, auto restart and can interface directly with other peripherals/external inputs.

More Information
Hardware Limit Timer (HLT)

The Hardware Limit Timer (HLT) can detect faults in motors, power supplies, and other external devices. It can automatically notify the system to make provisions to shut down and/or safely restart.

More Information
24-bit Signal Measurement Timer (SMT)

The 24-bit Signal Measurement Timer (SMT) performs high-resolution measurements of any digital signal in hardware, resulting in near zero latency and high performance when decoding custom communications protocols or signaling.

More Information
Configurable Logic Cell (CLC)

The Configurable Logic Cell (CLC) offers hardware-based combinational and sequential logic functions to simplify and accelerate many common tasks. The CLC can also be used as “glue” logic between peripherals, eliminating the need for CPU intervention during steady-state activity in complex control loops.

More Information
Windowed Watchdog Timer (WWDT)

The Windowed Watchdog Timer (WWDT) is a system supervisory circuit that generates a reset when software anomalies are detected within a configurable critical window.

More Information
Peripheral Pin Select (PPS)

Peripheral Pin Select (PPS) provides ultimate flexibility when routing digital signals to device pins. With PPS, any digital peripheral can be connected to any I/O pin on-the-fly for a customized layout. This allows users to maintain layout compatibility with older PIC® MCUs, even as new features are implemented.

More Information
Advanced Memory Features

Memory Access Partition (MAP) supports customers in data protection and bootloader applications. Device Information Area (DIA) is a dedicated memory space for factory programmed device ID and peripheral calibration values.

Power Conserving Functionality

IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption. The device features the industry leading eXtreme Lower Power (XLP) technology.
