PIC16LF19176T-I/MV Overview
A PIC microcontroller is a compact, self-contained computer-on-a-chip that integrates a CPU, non-volatile program memory, RAM, and peripherals such as timers, ADC, communication interfaces, and I/O onto a single silicon die. PIC microcontrollers sit within the broader hierarchy of microcontrollers (MCU) -> microprocessors -> embedded computing devices -> semiconductors, and the PIC16 family specifically targets low-power, mid-complexity applications. The XLP variants add nanoWatt sleep modes and ultra-low standby currents, enabling years of operation from coin-cell or primary batteries. Core Independent Peripherals (CIPs) like the Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT) execute logic without CPU intervention, freeing the core and reducing active power.
Key features include integrated LCD drive (up to 96 segments) with on-chip charge pump, four 16-bit timers, four CCP/ECCP plus CWG peripherals, Peripheral Pin Select (PPS) for flexible signal routing, and an RTCC with calendar mode. CRC/SCAN hardware supports non-intrusive memory integrity checks. The device is supported by Microchip's MPLAB X IDE, XC8 compiler, and MCC code configurator, providing a complete firmware development chain from prototype through production.
Typical applications include battery-powered LCD consumer products such as thermostats, electronic shelf labels, blood glucose meters, and remote controls. Industrial HMI panels, sensor node data loggers, and metering front-ends also benefit from its rich peripheral set and low sleep current. The integrated 12-bit ADC2 and 5-bit DAC simplify analog signal conditioning in measurement products without requiring external components.
When designing with this device, plan the pinout using the Peripheral Pin Select (PPS) feature, which remaps digital peripherals to a wide range of I/O pins. Decouple VDD with a 0.1 uF X7R ceramic placed within 3 mm of the package, and place the VCAP pin capacitor (1 uF to 10 uF) as close as possible to maintain LDO stability. Always configure unused I/O as outputs low to minimize current leakage in sleep mode.

Typical Applications
PIC16LF19176T-I/MV is suitable for 6 applications: Battery-Powered Thermostat with LCD, Electronic Shelf Label (ESL) Wireless Display, Portable Medical Glucose Meter, Industrial Sensor Data Logger, Smart Remote Control with LCD, IoT Sensor Node with BLE Beacon.
Battery-Powered Thermostat with LCD
The PIC16LF19176T-I/MV is purpose-built for battery-powered thermostats where its integrated LCD driver (up to 96 segments) eliminates an external display controller and its XLP sleep current below 1 uA enables 5+ year battery life on 2xAA cells. The 12-bit ADC2 reads temperature from a thermistor or digital sensor with 0.1 C resolution, while the RTCC maintains timekeeping across power events. Designers can drive a custom-segment LCD directly via the on-chip charge pump without a boost converter, reducing BOM cost by $0.50 to $1.00 per unit. Pin count and PPS flexibility simplify PCB routing for wall-mounted enclosures.

Electronic Shelf Label (ESL) Wireless Display
The PIC16LF19176T-I/MV's low 1.8 V to 3.6 V operation and sub-uA XLP sleep currents make it ideal for ESL tags where coin-cell batteries must last 5 to 10 years. The on-chip LCD driver supports 96-segment reflective displays common in retail signage, while the 32 MHz CPU handles RF protocol stacks for sub-GHz or BLE companion chips via SPI. The 28 KB Flash accommodates small OTA-style firmware update payloads, and the CRC/SCAN peripheral provides memory integrity checks critical for unattended retail deployments. Wide industrial temperature range ensures stable operation across store environments.
Recommended
Portable Medical Glucose Meter
The PIC16LF19176T-I/MV meets portable medical device demands with its low-power XLP modes, integrated 12-bit ADC2 for accurate electrochemical strip reading, and 5-bit DAC for strip-bias control. The RTCC provides accurate time-stamping of measurements for patient history logs, and 256 bytes of EEPROM-like data Flash stores calibration constants across battery replacements. Industrial temperature grade (-40 C to +85 C) supports storage and transport across varied conditions. PPS routing enables flexible PCB layouts for compact handheld enclosures while the UQFN-40 (5x5) package keeps board area under 25 mm x 25 mm.

Industrial Sensor Data Logger
The PIC16LF19176T-I/MV serves industrial data loggers with its 28 KB Flash for buffering thousands of timestamped samples, 2 KB SRAM for moving-window averaging, and 256 bytes EEPROM for non-volatile configuration. The 12-bit ADC2 samples thermocouples, pressure transducers, or 4-20 mA loop signals at up to 100 ksps with hardware averaging. XLP sleep currents below 1 uA let battery-powered loggers run for years in field deployments, while the wide 1.8 V to 3.6 V supply supports direct 3.6 V lithium thionyl chloride primary cells. EUSART enables RS-485 multi-drop networks common in industrial automation.
Recommended
Smart Remote Control with LCD
The PIC16LF19176T-I/MV powers universal smart remote controls where its integrated LCD shows menu navigation, input source, or streaming service status. The 12-bit ADC2 reads battery voltage for accurate fuel gauging of rechargeable Li-ion cells, while the RTCC times scheduled recordings and sleep timers. CWG and CCP peripherals drive infrared LEDs with precise carrier frequencies for legacy TV/AVR control, and PPS allows the IR driver to be placed on any I/O pin for optimal PCB antenna layout. XLP features deliver 6-month battery life on 2xAAA cells under typical use patterns.
Recommended
IoT Sensor Node with BLE Beacon
The PIC16LF19176T-I/MV serves as the host MCU for Bluetooth Low Energy beacon-based IoT sensor nodes, controlling a companion RN4870 BLE module over UART. The 32 MHz CPU handles sensor polling, BLE event processing, and sleep/wake duty cycling while XLP modes keep average current below 10 uA. The 12-bit ADC2 reads environmental sensors (temperature, humidity, light), and 256-byte EEPROM stores device IDs and calibration data. The UQFN-40 (5x5 mm) package fits inside small coin-cell powered sensor enclosures, and PPS routing minimizes external wiring for compact wearable form factors.

Design Notes
The PIC16LF19176T-I/MV achieves sub-uA sleep current with the RTCC running when configured per Microchip AN2344 nanoWatt XLP guidance. Disable unused peripherals via PMD registers before entering Sleep, set all unused I/O as outputs driving low to eliminate input-leakage paths, and use the internal LFINTOSC for RTCC rather than a 32 kHz external crystal when sub-uA targets are needed. Always pull MCLR high through a 10 kohm resistor and avoid floating digital inputs.
Place the single 0.1 uF X7R VDD decoupling capacitor within 3 mm of the VDD pin (pin 17) and a bulk 1 uF to 10 uF near the package. The UQFN-40 (MV) package uses an exposed pad on the underside that must be soldered to a 5x5 mm copper pad with thermal vias to a ground plane for heat dissipation. For the LCD segment lines, route traces with 0.2 mm clearance and avoid routing noisy digital signals (PWM, SPI clocks) parallel to the LCD segments.
Do not configure PPS outputs to pins that share analog functions without first disabling the analog peripheral - this causes signal contention and excess current. The LF-version silicon requires VDD always above 1.8 V for reliable Flash programming; budget for battery end-of-life voltage when designing battery-replaceable products. The RTCC requires VBAT backup configuration (DS3231-style switchover) for accurate timekeeping across VDD loss, and the SECCP/PWM outputs must be assigned to PPS-capable pins.
For 32 MHz operation, the internal HFINTOSC is factory-calibrated to +/- 1 percent across 0 C to +85 C, eliminating the need for an external crystal in most designs. For UART/RS-485 communications requiring tight baud-rate accuracy, switch to the 16 MHz HFINTOSC with PLL or attach a 16 MHz external crystal with two 15 pF load capacitors. Route SPI and UART traces with matched lengths and ground-referenced shielding to avoid crosstalk with sensitive ADC2 inputs on adjacent pins.
Compliance Information
RoHS compliant per Microchip product page. MSL-1 moisture sensitivity rating allows unlimited floor life before reflow. Operating temperature grade -I (industrial) covers -40 C to +85 C; not AEC-Q100 qualified - choose AEC-Q100 equivalent part for automotive.
