PIC16F19175-E/MV - 8-Bit 32MHz 14KB Flash XLP MCU | Microchip
MPN: PIC16F19175-E/MV ✓ פעילPIC16F19175-E/MV סקירה
An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction per clock cycle (excluding branches), positioning it within the microcontroller hierarchy: PIC16 -> PIC microcontrollers -> 8-bit MCU family -> microcontroller -> embedded semiconductor -> integrated circuit. PIC16F19175 belongs to the enhanced mid-range core family and is engineered for low-power, peripheral-rich applications where deterministic behaviour and long battery life are mandatory.
Key features include the integrated charge pump that maintains LCD contrast even when the battery voltage drops below the LCD threshold, high-current I/O for direct LED drive, and Intelligent Analog peripherals that operate independently of the CPU. The wide operating voltage range of 2.3V to 5.5V accommodates 2-cell alkaline, NiMH, and primary Li-coin chemistries. Sleep currents in the nanoamp range extend shelf life in always-on products.
The PIC16F19175-E/MV uses an enhanced mid-range PIC16 core with a 14-bit instruction word and hardware multiplier assist. The 32MHz internal oscillator removes the need for an external crystal in cost-sensitive designs, while the Peripheral Pin Select (PPS) remapping allows digital peripherals to be routed to a wide range of I/O pins, simplifying PCB layout when functions move late in the design cycle. The 5x5 mm UQFN package with exposed thermal pad supports compact, thermally efficient layouts.
Typical applications include battery-powered LCD consumer products, IoT sensor nodes with segmented displays, medical glucose meters and thermometers, industrial metering with on-glass LCD readouts, and automotive body controllers. The combination of XLP current profiles, on-chip LCD drive, and the charge pump makes the part especially well suited for portable devices that must display data without an external boost converter.
When designing with this device, allocate PCB copper directly under the exposed thermal pad and stitch vias into the inner ground plane to meet thermal and EMI targets. Use Microchip's MPLAB X IDE with XC8 compiler and MPLAB Code Configurator (MCC) for peripheral setup; the auto-generated code accelerates CIP configuration but should still be reviewed against the device datasheet's electrical characteristics.

יישומים טיפוסיים
PIC16F19175-E/MV מתאים עבור 6 יישוםs: Battery-Powered LCD Thermometer, IoT Sensor Node with Segmented Display, Industrial Metering with On-Glass LCD, Portable Consumer Electronics with LCD UI, Automotive Body and Accessory Controllers, Medical Point-of-Care Diagnostic Devices.
Battery-Powered LCD Thermometer
The PIC16F19175-E/MV is well matched to a battery-powered digital thermometer because its integrated charge pump keeps the segmented LCD readable as the cell discharges below the panel threshold, eliminating an external boost converter. With 14 KB of Flash, the device holds temperature-conversion math, lookup tables, and a UI state machine without external memory. The XLP sleep current in the nanoamp range extends coin-cell life beyond one year, while the 12-bit ADC2 and on-chip low-power comparator directly interface NTC or digital sensors like the MCP9808 over I2C. The 32 MHz internal oscillator removes the need for an external crystal, reducing BOM cost. Use the RTCC peripheral for time-based logging and the SMT peripheral for precise temperature-event timing.
מומלץ
IoT Sensor Node with Segmented Display
The PIC16F19175-E/MV serves as the main MCU in an IoT sensor node that displays readings on a low-power segmented LCD while periodically transmitting over UART, SPI, or a sub-GHz transceiver. Its CIPs - CWG for complementary waveforms driving sensors, SMT for pulse-width measurement, ZCD for zero-crossing detection - run autonomously, allowing the CPU to sleep most of the time. The 1 KB of SRAM holds protocol buffers, and 256 bytes of EEPROM stores configuration across power cycles. The 40-pin UQFN package supports compact wearable and smart-sensor form factors, while the PPS peripheral pin select lets designers reassign digital functions late in the layout without rerouting the board.
מומלץ
Industrial Metering with On-Glass LCD
In an industrial electric, gas, or water meter, the PIC16F19175-E/MV drives the on-glass segmented LCD directly via its integrated charge pump, while the 12-bit ADC2 samples current/voltage transducers at high accuracy for billing-grade measurement. The RTCC keeps time-stamped consumption logs in EEPROM, and the ZCD and CWG peripherals support phase-angle control and tamper detection. The -40C to +125C industrial extended temperature grade ensures reliable operation in outdoor enclosures. The 32 MHz MIPS throughput handles IEC-style measurement algorithms in real time, while the XLP idle mode keeps standby power below the regulatory threshold for utility meters.
מומלץ
Portable Consumer Electronics with LCD UI
The PIC16F19175-E/MV suits portable consumer products such as electronic scales, kitchen timers, and remote controls that need an LCD status display but no graphical TFT. The integrated charge pump maintains LCD visibility across the battery discharge curve, while high-current I/O pins directly sink/source LED segments and backlight drivers without extra transistors. The eXtreme Low-Power (XLP) sleep currents extend shelf life in always-on products, and the 32 MHz instruction throughput lets designers add capacitive-touch or piezo feedback without compromising UI responsiveness. The 40-pin UQFN package fits slim enclosures.
מומלץ
Automotive Body and Accessory Controllers
In automotive body modules - interior lighting, seat controllers, HVAC panels, or accessory controllers - the PIC16F19175-E/MV provides LCD feedback for status display, 12-bit ADC2 for sensing analog inputs, and CIPs for signal conditioning and PWM-driven actuators. The industrial-extended -40C to +125C temperature range tolerates cabin and under-hood environments, and the wide 2.3V to 5.5V supply tolerates load-dump transients when paired with an external TVS. Designers should note this part is the standard (non-Q) grade; for AEC-Q100 qualified automotive duty, select the PIC16F19175-E/MVVAO or a Q-graded equivalent from the same family.
מומלץ
Medical Point-of-Care Diagnostic Devices
The PIC16F19175-E/MV powers compact medical point-of-care devices such as glucose meters, pulse oximeter front-ends, and INR monitors that require a clear numerical LCD readout and precise analog measurement. The 12-bit ADC2 reads photo-diodes or electrochemical test strips with low noise, while the low-power comparator and DAC support bias and reference generation. XLP sleep currents preserve battery shelf life, and the charge pump maintains LCD contrast through end-of-life battery voltage. The 14 KB Flash holds measurement algorithms and on-device UI without external memory. Hardware CIPs offload timing-critical tasks from the CPU, improving measurement repeatability.

הערות תכנון
The 40-pin UQFN (MV) package exposes a thermal pad on pin 39 that must be soldered to a ground copper pour with at least four thermal vias stitching into the inner ground plane. This keeps the junction temperature within the -40C to +125C operating range during sustained 32 MHz operation. Place 100 nF decoupling on VDD (pin 9) within 2 mm of the package, and a bulk 4.7 uF capacitor on VDD within 10 mm. The exposed pad also serves as the primary ground return, so do not rely on the perimeter VSS pin alone for high-current return paths.
Designers often overlook the LCD charge pump supply filtering. When the LCD is active, the charge pump draws short current pulses from VDD; without adequate bulk decoupling the supply rail can sag and induce ADC2 noise. Add a 10 uF ceramic + 1 uF ceramic in parallel near the LCD bias pins, plus a ferrite bead between VDD and the charge-pump supply rail if the application shows ADC reading drift correlated with LCD activity. The XLP sleep modes reduce IDD to nanoamp levels but require careful peripheral-state management on wake-up.
A common pitfall is leaving the MCLR/RE3 pin (pin 38) floating when configured as MCLR; this can cause spurious resets. Tie MCLR to VDD through a 10 kohm resistor or disable MCLR in CONFIG words. Another frequent mistake is failing to read the ADC2 in differential mode correctly - the 12-bit ADC2 supports both single-ended and differential conversions, and the sign bit interpretation differs. Always generate peripheral setup code with MPLAB Code Configurator (MCC) and cross-check the CONFIG words against the family datasheet.
