PIC16LF19176-E/PT Présentation
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals on a single die. Within the power-management hierarchy, MCUs sit at the device-control layer above sensors and below system-level SoCs, providing deterministic real-time control while drawing as little as microamps in sleep mode. The PIC16 family uses a RISC instruction set with 14-bit wide instructions and a Harvard architecture, making it well suited to cost-sensitive embedded designs.
Key features of the PIC16LF19176-E/PT include 28 KB Flash, 2 KB RAM, 256 bytes EEPROM, integrated 12-bit ADC2, 5-bit DAC, low-power comparators, PWM/CCP, CWG, SMT, ZCD, PPS, RTCC, hardware limit timer (HLT), windowed watchdog timer (WWDT), and peripheral module disable (PMD). The wide operating voltage range of 1.8 V to 3.6 V and XLP nanoWatt technology enable years of battery life in standby.
Typical applications include battery-powered LCD consumer products (thermostats, blood-pressure monitors, e-bike displays), IoT sensor nodes, home-automation keypads/HMI, low-cost industrial control, and metering panels. The integrated LCD charge pump and segment driver reduce BOM cost by eliminating an external voltage booster.
Designers should evaluate sleep current (claimed nanoWatt), wake-up latency, and segment-count requirements when choosing this part. The 44-TQFP package offers generous I/O count but should be paired with a clean 3V LDO for analog performance.

Applications typiques
PIC16LF19176-E/PT convient pour 7 applications: Battery-Powered LCD Thermostats, Medical Wearable / Health Monitor, Home Automation Keypad / HMI, Industrial Sensor Node, Smart Metering Display Panel, IoT Sensor / BLE Beacon Front-End, Consumer LCD Remote Control.
Battery-Powered LCD Thermostats
The PIC16LF19176-E/PT integrates an LCD segment driver with built-in charge pump, 12-bit ADC2 for thermistor or analog temperature sensing, and RTCC for timekeeping - all from a 1.8-3.6 V supply. Designers can run the MCU at nanoWatt sleep currents with LCD and RTCC retained, and a single CR2032 coin cell can power a thermostat for 5+ years. Compared to using an external LCD driver, the integrated path saves 4-6 USD BOM and ~25 mm2 of PCB.
Recommandé
Medical Wearable / Health Monitor
The PIC16LF19176-E/PT suits battery-powered medical wearables such as blood-pressure cuffs and glucose meters thanks to its 12-bit ADC2 for sensor readout, 5-bit DAC for sensor excitation, and XLP sleep current. The RTCC tracks time-stamped measurements, and the integrated LCD displays readings without an external driver IC. With WWDT and CRC/SCAN, design houses can meet basic IEC 60730 functional-safety expectations for home medical devices.
Recommandé
Home Automation Keypad / HMI
Wall-mounted keypads and HVAC HMI panels benefit from the PIC16LF19176-E/PT's matrix-scan-capable I/O, integrated LCD for status display, and ZCD for mains-voltage zero-crossing detection in dimmer circuits. The hardware limit timer (HLT) simplifies capacitive-touch debounce, and the PWM drives LED backlights at high efficiency. With the CWG peripheral, designers can also generate complementary PWM for motor or valve control without software overhead.
Recommandé
Industrial Sensor Node
Industrial 4-20 mA or 0-10 V sensor nodes leverage the PIC16LF19176-E/PT's 12-bit ADC2, low-power comparators for threshold detection, and ZCD for AC-line sensing. The 1.8-3.6 V supply and small TQFP footprint fit sealed cable-mounted sensor heads. WWDT, CRC/SCAN, and HLT add field-reliable diagnostics, while the integrated 5-bit DAC closes a low-cost loop for actuator control.
Recommandé
Smart Metering Display Panel
Smart electricity, water, and gas meters use the PIC16LF19176-E/PT to drive segmented LCDs showing consumption, time, and tariff data without an external charge pump. RTCC tracks billing periods; the integrated LCD bias generator drives up to 360 segments in the 44-TQFP variant. ZCD and low-power comparators interface directly with metrology front-ends, while XLP nanoWatt sleep retains LCD and RTCC on a single primary cell for the meter's lifetime.
Recommandé
IoT Sensor / BLE Beacon Front-End
Battery-driven IoT sensors and BLE beacons pair the PIC16LF19176-E/PT with an external RN4870 or BTLC1000 Bluetooth module. The MCU's PPS, 12-bit ADC2, and SMT peripheral simplify sensor sampling, while XLP sleep modes stretch coin-cell life past 2 years. PWM drives status LEDs, and the CWG generates timing waveforms for ultrasonic or IR sensors. The 44-TQFP leaves ample I/O for future feature expansion.
Recommandé
Consumer LCD Remote Control
Universal TV and appliance remotes use the PIC16LF19176-E/PT's integrated LCD for status feedback, CWG/PWM for IR carrier generation, and ZCD for AC-line synchronization on learning remotes. The 1.8-3.6 V supply matches two AAA cells directly; HLT and WWDT ensure reliable keypad debounce and reset behavior. Compared with bare PIC16LF184x designs, the integrated LCD eliminates a separate driver chip.

Notes de conception
Decouple VDD and VDDCORE with 100 nF and 1 uF ceramics placed within 3 mm of the pins. Use the IDLE and DOZE modes for short-period active bursts; combine with Sleep with RTCC and LCD retained to reach XLP nanoWatt levels. Avoid switching the ADC on while in Sleep because the ADC2 bias block draws hundreds of microamps - gate it through PMD before entering Sleep. Estimated: with 100% Sleep duty cycle at 25C, expected Iq is below 100 nA for the LCD + RTCC retention mode per the Microchip PIC16LF19176 datasheet DS40001941D.
Route the 32.768 kHz crystal traces short and symmetric with a guard ring to AVSS for stable RTCC operation. Place the LCD segment traces on a single layer with no crossovers to minimize ghost-segment coupling. The 44-TQFP thermal pad is not present on this package, but a copper pour under the exposed leads improves assembly yields and helps with thermal spreading for higher MIPS operation.
Do not exceed 3.6 V on the LF variant or 5.5 V on the F variant; the on-chip charge pump can source LCD bias voltages but is not a power supply for external loads. MCLR must be tied high through a 10 kOhm pull-up if not driven by an external supervisor. The PPS peripheral allows flexible pin mapping, but a misconfigured PPS register can lock out the programming pins - keep the ICSP PGx and PGDx lines reserved in your code.
Use the dedicated analog supply AVSS / AVdd pins (where present on the package variant) for ADC and reference circuitry; route analog traces away from PWM and PWM-CWG outputs to avoid digital-noise coupling into the 12-bit ADC2 result. For high-impedance sensor sources, enable the ADC2 charge-sharing reduction mode and add a software oversampling filter to recover ENOB.
Informations de conformité
RoHS compliant per Microchip product page. The PIC16LF19176-E/PT is not AEC-Q100 qualified; designers targeting automotive applications should consider PIC16F19176-E/P or dsPIC33 variants with automotive grade.
