PIC16F19176-I/MV - 8-bit XLP MCU, 28KB Flash, 32MHz | Microchip
MPN: PIC16F19176-I/MV ✓ Hoạt độngPIC16F19176-I/MV Tóm tắt
An 8-bit microcontroller (MCU) is a programmable processor that executes instructions one byte at a time using an 8-bit data path. The PIC16 family sits in the broader taxonomy of microcontrollers -> embedded processors -> semiconductors, while XLP (eXtreme Low Power) variants add deep-sleep current management for coin-cell and energy-harvesting applications. The 8-bit PIC16 core provides deterministic instruction execution and a Harvard architecture that simplifies real-time control loops.
Key features include a 2.3V to 5.5V supply range, 32 MHz internal oscillator, 12-bit ADC2 with computation, 5-bit DAC, two comparators with selectable references, peripheral pin select (PPS), and an integrated LCD driver supporting up to 320 segments. The device also provides a charge pump that maintains LCD contrast even at low battery voltage, high-current I/O for direct LED drive, and Core Independent Peripherals (CIPs) such as CWG and SMT that offload timing tasks from the CPU.
Technically, the PIC16F19176 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and 16-level hardware stack. Its XLP architecture supports sleep currents in the sub-microamp range with RTCC and peripherals running, and the integrated LCD charge pump allows glass driving down to 1.8V VDD when configured appropriately. The 40-pin UQFN package minimizes PCB area while exposing the full peripheral set, and PPS enables flexible peripheral-to-pin assignment without re-routing the board.
Typical applications include battery-powered medical glucose meters, IoT sensor nodes with LCD readouts, industrial HMI panels, smart thermostats, home appliance user interfaces, and portable instrumentation. The wide operating voltage and integrated LCD charge pump simplify single-coin-cell designs that need a glass display.
When designing, place decoupling capacitors within 2 mm of each VDD/VSS pair and follow the recommended ground-return layout for the LCD charge pump capacitors. The PPS feature allows peripheral reassignment post-build, so reserve unused pins in the schematic as a routing safety net.

Ghi chú thiết kế
The PIC16F19176-I/MV XLP architecture achieves sub-1 uA sleep current with RTCC running, enabling multi-year coin-cell operation. To minimize active current, switch the CPU to the 32 kHz LFINTOSC during idle loops and gate unused peripherals via PMD registers. The integrated LCD charge pump allows direct battery connection, but the charge-pump flying capacitor (typically 1 uF X7R) must be placed within 3 mm of the VLCD pins to minimize ripple.
Place all VDD/VSS decoupling capacitors (100 nF X7R) within 2 mm of the respective pins. The UQFN-40 package exposes a central thermal pad that must be soldered to a ground copper pour of at least 25 mm^2 to meet thermal and electrical performance. Avoid routing high-speed digital signals (PWM outputs, oscillator traces) directly beneath the LCD charge-pump capacitors to prevent injected noise on the bias rails.
When using Peripheral Pin Select (PPS), reserve unused I/O pins in the schematic as routing flexibility for late-stage peripheral reassignment. The ICSP pins (RB6/RB7) should remain accessible for in-circuit programming and debugging; do not assign them to output-only peripherals. For LCD glass, route SEG and COM traces with equal length where possible to minimize ghost-segment effects and keep traces away from high-current switching nodes.
Do not exceed 5.5 V on any pin; the PIC16F19176-I/MV is not 5 V tolerant on all pins. Always configure unused I/O as outputs driven low to minimize sleep current. When migrating from PIC16F18855, remember that the LCD charge-pump capacitor values differ - consult the PIC16F19176 datasheet for the exact VLCD flying capacitor selection, otherwise contrast will degrade at low battery voltages.
