PIC16LF19175T-I/PT - 8-bit 32MHz 14KB Flash MCU | Microchip
MPN： PIC16LF19175T-I/PT ✓ 啟用中PIC16LF19175T-I/PT 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), non-volatile storage (EEPROM), and a rich set of peripherals such as timers, ADCs, communication interfaces, and I/O ports. Within the broader taxonomy, the PIC16LF19175 belongs to the 8-bit MCU category, which sits under microcontrollers, then embedded processors, and finally semiconductors. Its nanoWatt XLP pedigree makes it a representative member of the ultra-low-power MCU class used in energy-harvesting and battery-powered designs.
Key features include an integrated LCD driver with charge pump, a 12-bit ADC2 with computation, a 5-bit DAC, low-power comparators (LP COMP), PWM, CCP, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), RTCC (Real-Time Clock Calendar), HLT (Hardware Limit Timer), WWDT (Windowed Watchdog Timer), and PMD (Peripheral Module Disable). The combination of PPS and PMD gives system designers granular control over pin routing and unused peripheral power-down to extend battery life.
The architecture is built on Microchip's enhanced mid-range PIC16 core, providing deterministic instruction execution at 32 MHz with a 31.25 ns instruction cycle. The internal 32 MHz oscillator, optional 32 kHz low-power oscillator, and PLL flexibility allow trade-offs between active power, sleep current (claimed down to nanoampere class), and timing accuracy. The 12-bit ADC2 with computation automates averaging, filtering, and threshold decisions on-chip, offloading the CPU.
Typical applications include battery-powered IoT sensor nodes, thermostat and HVAC control panels with LCD readouts, metering (gas/water/electric), home appliance user interfaces, portable medical devices, and industrial human-machine interface (HMI) terminals. The integrated LCD driver and RTCC make it especially well-suited to mains- or battery-powered clock/display products.
When designing, validate the minimum operating voltage for the chosen clock frequency and engage peripheral module disable (PMD) and sleep modes aggressively to achieve the headline nanoWatt XLP figures. For LCD designs, allocate sufficient bias resistor values for the chosen glass and use the charge pump only when VIN is below the LCD threshold voltage.

典型應用
PIC16LF19175T-I/PT 適用於 6 應用s: Battery-Powered IoT Sensor Node, Thermostat / HVAC Control Panel with LCD, Utility Metering (Gas / Water / Electric), Home Appliance User Interface, Portable Medical Device, Industrial HMI Terminal.
Battery-Powered IoT Sensor Node
The PIC16LF19175T-I/PT is well-suited for battery-powered IoT sensor nodes thanks to its nanoWatt XLP technology and 1.8 V minimum Vdd. Its 12-bit ADC2 with computation performs on-chip averaging, threshold detection, and oversampling, offloading the CPU so the core can stay asleep longer. Per the datasheet, sleep current drops into the nanoampere range when peripherals are individually disabled via the PMD registers, and the integrated RTCC keeps accurate time-stamping without waking the main oscillator.
推薦
Thermostat / HVAC Control Panel with LCD
The integrated segmented LCD driver with on-chip charge pump lets the PIC16LF19175T-I/PT drive a glass display directly from a low-voltage battery, simplifying the BOM of a thermostat or HVAC controller. The charge pump maintains contrast even when Vdd falls below the LCD threshold, while RTCC keeps wall-clock time during mains or backup-battery brownouts. PPS provides flexible pin assignment for keys, relays, and triac drivers on the same 44-TQFP footprint.
推薦
Utility Metering (Gas / Water / Electric)
For gas, water, or electricity meters, the PIC16LF19175T-I/PT combines a 12-bit ADC2, low-power comparators, RTCC, and LCD drive on a single chip, enabling long-life battery metering designs. The ZCD (Zero-Cross Detect) and CWG peripherals support dimming and tamper detection, while the 256-byte EEPROM retains calibration constants across decades of operation. Its 44-TQFP package offers ample I/O for pulse outputs, optical interfaces, and wireless M-Bus modules.
推薦
Home Appliance User Interface
Appliance front panels benefit from the PIC16LF19175T-I/PT's LCD driver, PWM, and CCP for direct control of buzzers, triac-fired heaters, or LED indicators without external logic. With up to 32 MHz operation the core responds quickly to capacitive touch or rotary encoder inputs while still dropping to deep sleep between user interactions. PPS remaps peripheral functions to free pins for flexible PCB routing of mixed-signal and power-stage signals.
推薦
Portable Medical Device
Portable medical devices such as pulse oximeters, glucose meters, and digital thermometers benefit from the PIC16LF19175T-I/PT's low-voltage operation, 12-bit ADC2 precision, and nanoWatt XLP sleep modes. The integrated LCD driver eliminates a separate display controller, reducing both BOM cost and quiescent draw, while the RTCC keeps accurate usage logs for compliance. Operating across -40C to +85C, the part is suitable for body-worn and handheld environments.
推薦
Industrial HMI Terminal
Industrial HMI terminals with character or segment LCDs benefit from the PIC16LF19175T-I/PT's generous 14 KB Flash and 1 KB SRAM, enough to host menu state machines, Modbus-style protocol stacks, and keypad debounce logic. The 12-bit ADC2 supports 4-20 mA or 0-10 V analog input conditioning, and the CWG/SMT peripherals generate precise timing for safety-critical outputs. Industrial-grade -40C to +85C operation and the 44-TQFP package suit panel-mount enclosures.

主要差異化特點

- nanoWatt XLP technology with PMD granularity (對比PIC16LF19177T-I/PT)
設計說明
To achieve the nanoWatt XLP headline figures, aggressively engage sleep modes (SLEEP instruction) and use the Peripheral Module Disable (PMD) registers to power down unused peripherals on entry and re-enable them only when needed. Estimated: with ADC2, CWG, SMT, RTCC and LCD disabled, datasheet sleep current falls into the sub-microampere region; add 10 nA-100 nA typical per active peripheral.
Place the bulk Vdd/Vss decoupling capacitor (>=1 uF ceramic) within 5 mm of pins 22 and 31, and add a 100 nF bypass close to each pair. Keep ICSPCLK (RB6) and ICSPDAT (RB7) routed with short, parallel traces and series resistors near the MCU if the production environment includes in-circuit programming. Avoid routing analog and digital signal traces across the LCD segment pins to reduce cross-coupling on the glass.
Operating the device above 32 MHz requires Vdd >= 2.5 V per the datasheet; running at full speed below that threshold causes oscillator instability and code mis-execution. The PPS remapping must be explicitly configured before any peripheral is enabled, otherwise digital functions default to fixed pins and software appears to fail silently. For LCD designs, enable the integrated charge pump only when Vdd is below the panel threshold; otherwise the bias resistors alone provide adequate contrast and save quiescent current.
