PIC16LF1907-E/PT 개요
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), working memory (RAM), non-volatile data memory (EEPROM), and a rich set of on-chip peripherals such as timers, ADC, communication interfaces, and I/O. MCUs sit at the lowest tier of the embedded computing hierarchy and are the primary building blocks of every modern embedded system. The PIC® XLP™ (eXtreme Low Power) family extends this by offering nanoWatt sleep currents below 50 nA, making these parts well-suited to battery-powered and energy-harvesting designs.
Key features of the PIC16LF1907-E/PT include integrated LCD drive support, an on-chip 10-bit ADC, multiple Enhanced USART, I²C, and SPI interfaces, and the nanoWatt XLP technology that delivers sub-microamp sleep currents. The 44-pin TQFP package provides generous I/O count (36 I/O pins) while remaining hand-solderable for prototypes, and Microchip's extensive MPLAB X IDE ecosystem (XC8 compiler, MPLAB Snap debugger) makes firmware development low-friction.
Architecturally, the device uses Microchip's enhanced mid-range 8-bit RISC core with a 14-bit instruction word and a hardware multiplier, allowing compact code and efficient C compilation. The XLP technology combines multiple low-power modes (Sleep, Idle, Doze) with peripheral clock gating, allowing wake-up event-driven operation that can extend battery life from years to decades depending on duty cycle.
Typical applications include battery-powered consumer devices, industrial sensor nodes, low-cost LCD user interfaces, home automation, IoT edge nodes, and metering. The integrated LCD driver simplifies designs that need a small alphanumeric or segment display without an external charge-pump IC.
When designing with this part, ensure the configured clock source (internal LF oscillator or external crystal) matches your power-budget and timing-accuracy needs. Decoupling capacitors (100 nF + 10 µF bulk) must be placed within a few millimetres of VDD/AVDD pins, and unused I/O should be configured as outputs low to minimise current leakage.

일반적인 애플리케이션
PIC16LF1907-E/PT 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, Industrial Sensor Transmitter with LCD, Consumer Appliance User Interface, Smart Meter / Utility Endpoint, Home Automation / Building Control, Portable Medical Monitoring Accessory.
Battery-Powered IoT Sensor Node
The PIC16LF1907-E/PT suits battery-powered IoT sensor nodes because its 1.8 V to 3.6 V supply range matches single-cell Li-ion and two-AA chemistries, while nanoWatt XLP sleep currents drop below 1 µA for years of standby. With 14 KB flash and 512 B RAM the MCU handles periodic sensor reads, edge filtering, and short LoRa/BLE packet bursts. The integrated ADC and EUSART/SPI/I²C peripherals remove the need for an external ADC or level shifter. Real-world duty cycling of 0.1% extends a 2400 mAh battery beyond 10 years; engineers must configure Sleep + Watchdog Timer wake events and route the EUSART TX to a wake-on-byte ISR.
추천
Industrial Sensor Transmitter with LCD
The PIC16LF1907-E/PT is a strong fit for industrial sensor transmitters needing on-board indication: its integrated segment LCD driver eliminates an external charge-pump IC, and 36 I/O pins support multiple 4-20 mA loops, HART modems, and isolated SPI sensor front-ends. The Extended -40 °C to +125 °C temperature grade meets IEC 60068 industrial environmental specs. With 14 KB flash, calibration routines and linearisation tables fit comfortably, and the 10-bit ADC plus internal voltage reference enable ratiometric measurements. Use the nanoWatt XLP Sleep between conversions to keep dissipation under 1 mW and pass EMC tests with proper PCB layout.
추천
Consumer Appliance User Interface
For consumer appliances such as coffee machines, microwaves, and washing machines, the PIC16LF1907-E/PT provides a segment LCD interface, capacitive-touch capable I/O, and PWM channels to drive buzzers and triac-controlled heaters. The 14 KB flash stores UI state machines and EEPROM emulates user preferences; the 1.8-3.6 V range simplifies direct battery or USB-bus power. The 44-TQFP hand-solders cleanly for low-volume SKUs and supports surface-mount production at scale. Compared with discrete 8051 designs, the integrated LCD driver plus XLP idle modes cut BOM cost and standby current substantially.
추천
Smart Meter / Utility Endpoint
The PIC16LF1907-E/PT powers smart-meter endpoints where its 14 KB flash holds metrology code, LCD segment driver displays kWh readings, and the EUSART interfaces to a PLC or RF mesh modem. Extended temperature grade ensures reliability in outdoor enclosures; nanoWatt XLP sleep preserves battery life on outage reporting. The 10-bit ADC is adequate for single-phase energy measurement when paired with a current shunt; an SPI-controlled AFE can be added for higher accuracy. Microchip's MPLAB X ecosystem accelerates certification, and the 44-TQFP footprint eases PCB reuse across residential and commercial meter families.
추천
Home Automation / Building Control
The PIC16LF1907-E/PT drives home automation controllers (thermostats, blinds, lighting keypads) with its segment LCD driver showing status, EUSART/I²C connecting to wireless modules, and 20 MHz performance running state machines. Low-voltage operation permits direct 3.3 V supply from a small buck regulator, and XLP idle currents enable battery-backed devices such as wireless window sensors. The Extended temperature rating also covers attic and outdoor installations. Compared with discrete logic, this MCU integrates timing, comms, and display drive in one IC, simplifying FCC/CE EMC qualification and shrinking the BOM.
추천
Portable Medical Monitoring Accessory
For portable medical accessories (pulse-oximeter probes, pill reminders, glucose-meter peripherals) the PIC16LF1907-E/PT offers low-voltage operation from coin cells, sub-µA sleep for shelf-life targets, and 14 KB flash for firmware that includes basic digital filters on ADC samples. The integrated LCD driver shows readings without a power-hungry graphical display, and the 10-bit ADC handles pulse or temperature front-ends. While not AEC-Q100 qualified, the Extended -40 °C to +125 °C range suits medical accessory environments. The 44-TQFP also fits compact handheld enclosures and supports low-volume hand assembly for clinical trials.

설계 노트
Place a 100 nF decoupling capacitor within 5 mm of every VDD pin and a 10 µF bulk capacitor at the regulator output. The PIC16LF1907-E/PT has multiple VDD/VSS pairs - all of them must be decoupled. Configure unused I/O as outputs low to minimise leakage current, and select the LFINTOSC with a postscaler for the lowest sleep current (~50 nA typical) on battery-powered designs.
Route the ICSP pins (RB6/PGC, RB7/PGD) on your PCB with a 6-pin header compatible with MPLAB Snap, PICkit 4, or ICD 4. Keep the PGD/PGC traces short and away from switching nodes to avoid programming glitches. The 44-TQFP (10x10 mm) package has generous thermal pads and hand-solders cleanly with a fine tip; for production assembly use paste stencil apertures per IPC-7525 guidelines.
Do not assume the PIC16LF1907-E/PT is AEC-Q100 qualified - the 'E' suffix is only an extended temperature grade. For automotive designs, look at the PIC16LF1907-E/PT family members marked Q1 or consult Microchip automotive-grade alternatives. Also verify that the ICD/ICSP debug pins RB6/RB7 are not bound to external loads in production; high capacitance on these pins can disturb in-circuit debugging. Finally, configure the watchdog timer (WDT) in long-timeout mode for sleep-heavy apps to avoid unintended resets during wake-up bursts.
Estimated: at 20 MHz CPU, 3.3 V VDD, the active current is roughly 5 mA and power dissipation ~16.5 mW. The 44-TQFP theta_JA of approximately 50 C/W yields a junction rise of <1 C above ambient, so no heatsink is needed. However, in sealed outdoor enclosures with poor thermal paths, derate CPU activity to <50% duty to keep junction below 105 C in the 125 C-extended grade.
규정 준수 정보
ROHS3 Compliant per Microchip USA product page. 'E' suffix denotes Extended temperature grade (-40C to +125C) but is NOT equivalent to AEC-Q100 automotive qualification. For automotive designs, request Q1-graded variants from Microchip.
