PIC16LF19195T-I/PT Visão geral
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a range of integrated peripherals. The PIC16F family uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, sitting hierarchically between baseline PIC10/12 devices and the higher-performance PIC18 and dsPIC families. The XLP variants add nanoWatt technology with multiple low-power sleep modes (typically sub-uA idle) that allow battery-powered designs to last years on a single cell. Compared with 32-bit Cortex-M parts, 8-bit PIC MCUs trade raw throughput for deterministic interrupt response, simpler toolchains, and lower cost.
Key features include 1KB RAM, 256 bytes EEPROM, an integrated LCD driver with charge pump, 12-bit ADC with computation (ADC2), a 5-bit DAC, low-power comparators (LP COMP), multiple PWM/CCP/CWG channels, zero-cross detection (ZCD), peripheral pin select (PPS), and a battery-backed Real-Time Clock/Calendar (RTCC). High-current I/O pins are designed to directly drive LED backlighting without external transistors. Core Independent Peripherals (CIPs) such as CWG, NCO, and SMT off-load tasks from the CPU.
Architecturally the device uses a Harvard memory layout with separate program flash and SRAM buses, hardware stack, and 31 kHz LFINTOSC plus 16 MHz HFINTOSC internal oscillators. The internal voltage reference and charge pump allow display operation from a single 1.8-3.6V supply. Intelligent analog integration (ADC2 with oversampling and filtering) reduces the external signal-conditioning BOM.
Typical applications include battery-powered IoT sensor nodes with LCD displays, electronic shelf labels, medical glucose/thermometer meters, portable consumer appliances, and industrial HMI panels. The wide operating range and integrated LCD make it ideal for any mains-or-battery product that needs a segmented display without an external driver IC.
When designing, reserve adequate decoupling (100 nF + 1 uF) close to VDD/AVDD pins, and follow Microchip AN1365 (LCD layout) for the SEG/COM routing to minimize ghosting. This page combines distributor pricing, drop-in alternatives, and design guidance not found in the manufacturer datasheet alone.

Aplicações típicas
PIC16LF19195T-I/PT é adequado para 7 aplicaçãos: Battery-Powered IoT Sensor Node with LCD, Electronic Shelf Label (ESL) Display, Portable Medical Meter (Glucose / Thermometer), Industrial HMI Panel with Segmented LCD, Home Appliance User Interface, Automotive Aftermarket Accessory Controller, Smart Meter / Utility Display.
Battery-Powered IoT Sensor Node with LCD
The PIC16LF19195T-I/PT is ideal for coin-cell or 2xAAA powered IoT sensor nodes that display readings on a segmented LCD. Its XLP nanoWatt technology delivers sub-uA sleep current while the integrated LCD driver with charge pump drives up to 320 segments directly from a single 3V supply without a boost circuit, cutting BOM cost and quiescent draw. The 12-bit ADC2 with computation oversamples sensor inputs and triggers wake-up via the RTCC alarm, and the 14 KB flash accommodates BLE command stacks or simple state machines.
Recomendado
Electronic Shelf Label (ESL) Display
Electronic shelf labels need an MCU that can drive a segmented LCD, run for years on a coin cell, and communicate over a 2.4 GHz sub-GHz or BLE radio. The PIC16LF19195T-I/PT fits perfectly: its integrated LCD charge pump eliminates the external bias IC, and the XLP sleep modes drop consumption below 1 uA between RF transmissions. The 32 MHz core handles sub-GHz protocol stacks, and PPS lets the SPI/UART remap to suit the radio module. The 14 KB flash is sufficient for typical ESL firmware including display fonts.
Recomendado
Portable Medical Meter (Glucose / Thermometer)
The PIC16LF19195T-I/PT suits portable medical meters that need accurate analog measurements on a small battery with an LCD. The 12-bit ADC2 with computation provides oversampling and hardware averaging for thermistor or electrochemical sensor inputs, while the low-power comparators enable fast threshold detection for test-strip insertion. The integrated LCD driver shows measurement results without an external display IC, reducing BOM cost. AEC-Q100 grade parts in the same family are available for higher-reliability medical designs.
Recomendado
Industrial HMI Panel with Segmented LCD
Industrial HMI panels benefit from the PIC16LF19195T-I/PT's wide 1.8-3.6V operating range, integrated LCD driver, and Core Independent Peripherals. The CWG (Complementary Waveform Generator) handles power-supply half-bridge switching without CPU intervention, freeing the core to manage keypad scanning and display updates via DMA-friendly peripherals. PPS allows pin reassignment to simplify PCB routing when the LCD glass has a fixed pin map. The robust 64-TQFP package supports industrial temperature ranges.
Recomendado
Home Appliance User Interface
Microwave ovens, washing machines, and smart thermostats often use a segmented LCD driven by an 8-bit MCU. The PIC16LF19195T-I/PT integrates the LCD charge pump, button-input timer (SMT), and Zero-Cross Detect (ZCD) for TRIAC-driven loads in a single chip. This eliminates the external display driver and ZCD circuitry, reducing BOM cost and board space. The 32 MHz core runs the user-interface state machine with comfortable margin, while XLP idle keeps standby power within Energy Star limits.
Recomendado
Automotive Aftermarket Accessory Controller
Although the I-grade part itself targets industrial temperatures, the PIC16LF19195T-I/PT can be used in non-safety automotive accessory controllers such as dash cameras, ambient lighting, or auxiliary displays. The 12-bit ADC2 monitors battery voltage and current sensing, the RTCC timestamps events, and the CWG/PWM channels drive LED strings. The PPS matrix simplifies PCB layout when the display connector has non-standard pinout. For AEC-Q100 qualified applications, choose the -MV (extended) temperature variant.
Recomendado
Smart Meter / Utility Display
Smart electricity, water, or gas meters use the PIC16LF19195T-I/PT to drive the meter's segmented display, log consumption, and communicate with the utility's RF mesh. The RTCC with battery backup keeps time during power outages, while the ADC2 with computation performs precise metrology calculations. The XLP idle modes let the meter survive for years on its backup battery. The integrated LCD charge pump enables a single-LiSOCl2 cell design without external boost components.

Notas de projeto
The PIC16LF19195T-I/PT operates from 1.8V to 3.6V with XLP technology. Place a 100 nF ceramic decoupling capacitor within 3 mm of each VDD/AVDD pin pair, plus a bulk 1 uF to 10 uF on the main rail. Estimated: at 32 MHz active the core draws ~5 mA and at sleep with RTCC ~0.7 uA - plan coin-cell capacity accordingly. Use the on-board voltage regulator disable (ENVREG) and internal LDO mode to drop quiescent current when the supply is stable.
Follow Microchip AN1365 (LCD PCB layout guidelines) for SEG/COM trace routing. Keep LCD traces away from switching nodes and route them as a bus with consistent spacing to maintain segment contrast. Place the charge-pump capacitors (typically 1 nF to 100 nF) close to the LCDCAP pins. Use a guard ring around the analog AVSS/AVDD pair to keep digital switching noise out of the ADC2 measurement results.
Do not exceed 3.6 V on any VDD pin - the LF process is not 5V tolerant. Configure the PPS registers before enabling peripherals; a peripheral with unassigned pins will not operate even if its control registers appear correct. When using the MCLR pin as RE3, ensure the internal weak pull-up is enabled or leave the pin externally pulled high to avoid spurious resets. The ADC2 channel count depends on the package - the 64-TQFP variant exposes more analog channels than smaller pin-count packages.
