PIC16F19197 Product Family
Simplify the design of Low Power LCD Applications
The PIC16F19197 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. This 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.
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.
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.
The Curiosity High Pin Count (HPC) Development Board (DM164136) supports the PIC16F19197 product family. Curiosity Development Boards are cost-effective, fully-integrated MCU development platforms. The development board includes an integrated programmer/debugger and requires no additional hardware to get started.
The PIC16F19197 product family is also 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 Integrated Development Environments (IDEs), the downloadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE. Additionally, several Xpress code examples are available to help designers start development immediately.
Building Blocks for Real-Time Control
The Analog to Digital Converter with Computation helps accelerate common math tasks normally done in software by providing post-processing functions like averaging, low-pass filter, oversampling and threshold comparison.
The Zero Cross Detect module can monitor AC line voltage and indicate zero crossing activity. This information is made directly available to the on-board Waveform Generation peripherals for use in TRIAC control applications, greatly reducing both CPU demand and overall development cost by lowering the bill of materials.
Complementary Waveform Generator 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.
The Hardware Limit Timer 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.
The 24-bit Signal Measurement Timer 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.
The Configurable Logic Cell 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.
The CRC/SCAN module and the Windowed Watchdog Timer (WWDT) work in tandem to provide engineers with the tools necessary to incorporate functional safety into their application. By ensuring the integrity of the program FLASH contents, PICF19197 devices support the implementation of safety standards such as Class B and UL 1998.
Peripheral Pin Select 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.
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.
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.
