PIC16F19175-I/MV Übersicht
Background: A PIC microcontroller is an 8-bit RISC-class embedded processor built around a Harvard architecture with separate program and data buses, executing one instruction per clock cycle and supported by a rich set of Core Independent Peripherals (CIPs) that operate without CPU intervention. PIC microcontrollers sit within the broader hierarchy: microcontroller -> embedded processor -> semiconductor, and are widely used in ultra-low-power battery applications where deterministic behaviour and low quiescent current are critical. The XLP designation signals a part optimised for sub-uA sleep currents, making it a member of the power management ecosystem at the device level.
Key features include active current consumption in the microamp range, multiple low-power sleep modes (doze, idle, sleep), an integrated LCD charge pump that maintains contrast down to 1.8 V, and high-current I/O pins suitable for direct LED drive. The 12-bit ADC2 with averaging and accumulation, combined with the on-chip 5-/8-bit DAC and zero-cross detect, supports intelligent analog front-ends for sensor conditioning and motor control without external components.
Technical depth: the CIP block includes Complementary Waveform Generator (CWG), Configurable Logic Cell (CLC), Signal Measurement Timer (SMT), PWM, CCP, and Peripheral Pin Select (PPS), allowing timing-critical logic to run autonomously while the CPU sleeps. PPS remaps most digital peripherals to a wide choice of I/O pins, simplifying PCB routing on dense mixed-signal boards.
Typical applications span battery-powered LCD keypads, IoT sensor nodes, consumer white goods with LCD displays, and portable medical monitors requiring long standby time. The integrated LCD charge pump makes it ideal when the system must display information down to a nearly discharged battery.
When designing with this part, prefer PPS to route peripherals to the most convenient pins and exploit CIPs so the CPU can spend most of its time in sleep. Always validate sleep current against the application budget; the XLP spec is best realised when wake-up events are driven by CIPs rather than interrupts.

Typische Anwendungen
PIC16F19175-I/MV ist geeignet für 6 Anwendungs: Battery-Powered LCD Keypad, IoT Sensor Node, Consumer White Goods with LCD Display, Portable Medical Monitor, Industrial Control Panel HMI, Smart Home Thermostat.
Battery-Powered LCD Keypad
The PIC16F19175-I/MV is well suited to battery-powered LCD keypad products because its integrated LCD charge pump maintains contrast down to a 1.8 V supply, and the 14 KB Flash can host a full keypad-scan state machine. The 32 MHz CPU and Core Independent Peripherals (CLC, SMT, CCP, CWG) let the keypad polling and backlight PWM run autonomously while the CPU remains in XLP sleep. With 1 KB SRAM, 256 B EEPROM, and the 12-bit ADC2, the same MCU also handles battery voltage telemetry and temperature sensing without external components. The 40-pin UQFN (MV) footprint supports compact PCB layouts where the LCD driver pins are routed directly to the glass, simplifying BOM. Compared with discrete LCD drivers + an external MCU, the integrated solution cuts quiescent current by removing the inter-chip serial interface.

IoT Sensor Node
For IoT sensor nodes, the PIC16F19175-I/MV's XLP modes push sleep current into the microamp range while CIPs handle wake-on-event timing, freeing the CPU from active polling. The 12-bit ADC2 with computation can oversample and average sensor readings autonomously, reducing CPU wake-time and total energy per measurement. Peripheral Pin Select allows the UART/SPI/I2C to be routed to any I/O pin, simplifying PCB layout for radio modules. The 14 KB Flash holds small protocol stacks (Modbus, proprietary RF) and 1 KB SRAM is adequate for buffered payloads. PPS plus CLC enables custom glue logic without external gates, reducing BOM cost and power. The 40-pin UQFN provides enough I/O for multi-sensor fusion boards with temperature, humidity, and motion channels.

Consumer White Goods with LCD Display
The PIC16F19175-I/MV is a strong fit for consumer white goods such as washing machines, microwaves, and coffee makers that need a user-facing LCD and a responsive control panel. The integrated LCD driver supports up to 280 segments for menus and status icons without external drivers, while the on-chip CWG and PWM channels drive TRIAC or relay control of the load. The zero-cross detect (ZCD) and low-power comparators enable AC-line synchronous control and safety interlocks without external circuitry. With 14 KB Flash, designers can host UI flowcharts and fault diagnostics in a single MCU. Industrial temperature operation (-40 C to +85 C) covers kitchen and laundry environments. The 40-pin UQFN keeps the controller section compact within the appliance chassis.
Empfohlen
Portable Medical Monitor
Portable medical monitors benefit from the PIC16F19175-I/MV's XLP low-power operation, integrated 12-bit ADC2 for sensor front-ends, and on-chip LCD charge pump that keeps the patient display readable down to a low battery. The RTCC with calendar supports accurate timestamping of measurements without an external RTC chip. Core Independent Peripherals allow heart-rate or pulse-ox event detection to wake the CPU only when a clinical event occurs, preserving battery life for multi-day monitoring. The 14 KB Flash and 1 KB SRAM are sufficient for sensor fusion and small display update routines, while EEPROM stores calibration and patient-specific settings. Industrial temperature operation covers typical wearable and bedside monitor environments.
Empfohlen
Industrial Control Panel HMI
For industrial control panel HMIs, the PIC16F19175-I/MV provides a self-contained controller with LCD, pushbutton interface, and sensor inputs. The 12-bit ADC2 with computation supports 4-20 mA loop readings, while the on-chip DAC drives a 0-10 V control output or setpoint reference. Peripheral Pin Select and CLC simplify custom logic for safety interlocks and indicator LEDs without external gates. The 32 MHz core is fast enough for responsive HMI refresh rates, while XLP sleep modes keep panel quiescent current low during standby. The 40-pin UQFN allows dense routing on the back of the LCD glass. Industrial temperature operation covers factory floor environments.
Empfohlen
Smart Home Thermostat
Smart home thermostats leverage the PIC16F19175-I/MV's integrated LCD driver to display temperature and mode information, while its 12-bit ADC2 reads thermistor or analog temperature sensors with built-in averaging. The RTCC keeps time across power events, and the CWG plus PWM channels drive TRIAC-based load control for HVAC dampers or heater elements. The XLP low-power modes allow battery-backed thermostats to retain clock and schedule data over long power outages. The 14 KB Flash stores schedule logic and UI strings, while EEPROM retains user preferences. Peripheral Pin Select helps route buttons and LEDs to the most convenient PCB locations on slim thermostat faceplates.

Wichtigste Unterscheidungsmerkmale
- Industrial temperature grade in 40-pin UQFN MV package (vs. PIC16F19175-E/MV)
- Integrated LCD charge pump supports display down to 1.8 V (vs. PIC16F1519-I/P)
- Compact 40-pin UQFN (MV) 5x5 mm option vs 44-pin TQFP (vs. PIC16F19175-E/PT)
Designhinweise
Design the supply rail so the PIC16F19175-I/MV's VDD range of 1.8 V to 5.5 V is respected, including decoupling. Place a 100 nF ceramic as close as practical to each VDD pin and add a bulk 10 uF capacitor on the rail. When using the LCD charge pump, ensure the VLCD bypass is sized per the LCD glass load - insufficient capacitance causes display ripple. In battery applications, measure active current at the target VDD and clock setting; XLP figures are realisable only when wake events are driven by CIPs rather than CPU polling.
Route the UQFN (MV) thermal pad to a continuous ground copper pour under the part, stitched with vias to the inner ground plane. Keep the LCD segment pins adjacent to the LCD glass connector to minimise trace length. Use Peripheral Pin Select to place the high-speed digital peripherals (SPI, UART) on pins closest to their destination connectors, reducing EMI and ground bounce. Reserve pin pairs near the MCU for the external crystal if accurate timing is required for RTCC.
A common pitfall is forgetting to enable the PPS unlock sequence before remapping peripheral outputs - the device silently ignores the PPS writes if the sequence is wrong. Another is using the ADC2 in low-power modes without configuring the dedicated ADC clock source - the conversion accuracy will be wrong if the system clock is too slow. Finally, do not assume PIC16F19175 family variants share identical memory maps; PIC16F19176 may have a different SFR layout than PIC16F19175. Always check the specific datasheet silicon errata for the exact device revision in use.
