PIC16LF1907-I/P - 8-bit MCU, 14KB Flash, LCD, nanoWatt XLP
Teilenummer: PIC16LF1907-I/P ✓ AktivPIC16LF1907-I/P Übersicht
An 8-bit microcontroller (MCU) is a self-contained computing element with an 8-bit data path, on-chip Flash for program storage, on-chip SRAM for data, and a rich set of peripherals such as timers, ADC, comparators, communications (UART, SPI, I2C), and increasingly integrated analog/RF functions. MCUs sit within the broader semiconductor taxonomy of embedded computing devices -> microcontrollers -> integrated circuits. Within Microchip's portfolio, the PIC16F190x family targets cost-sensitive applications that need LCD segment drivers and extreme low-power operation, bridging simple PIC10/12/16 baseline devices and higher-end PIC18/PIC24 devices.
Key features of the PIC16LF1907-I/P include 14KB (8K x 14) Flash, 512 bytes RAM, an integrated LCD driver capable of driving segmented displays directly, 20MHz maximum clock, and nanoWatt XLP sleep modes that drop quiescent current into the sub-microamp range. The 40-pin PDIP package offers generous I/O for hand-wired prototypes, breadboarding, and legacy designs that prefer through-hole assembly over surface mount.
The PIC16LF1907 architecture pairs a RISC-style 14-bit instruction set with a Harvard memory structure, allowing simultaneous instruction fetch and data access. The integrated LCD module can drive up to a defined number of segment and common pins (per datasheet), eliminating the need for an external LCD driver. nanoWatt XLP technology provides multiple low-power modes (Idle, Sleep, and deep Sleep variants) that allow the MCU to wake on interrupts, timer overflows, or peripheral events.
Typical applications for the PIC16LF1907-I/P include battery-powered metering with LCD readouts, consumer appliances with segmented displays, handheld instrumentation, environmental sensors with LCD UI, and remote controls with low standby current. The 40-pin PDIP package is especially well suited to engineering prototypes and low-volume production runs that benefit from through-hole solderability and easy IC socket replacement.
When designing with this part, ensure the supply rail stays within the LF family's voltage window, place a 0.1uF decoupling capacitor close to VDD, and route the ICSP/PGD/PGC lines for in-circuit programming and debugging. The MPLAB X IDE with XC8 compiler is the canonical toolchain; the PICkit 3/Snap or MPLAB ICD 3/4 programmers support the device family for both Flash programming and in-circuit debug.

Typische Anwendungen
PIC16LF1907-I/P ist geeignet für 6 Anwendungs: Battery-Powered Metering with LCD Readout, Consumer Appliance Front Panels with LCD, Handheld Instrumentation and Testers, Environmental Sensor Nodes with LCD Display, Remote Controls and Wireless Key Fobs, Industrial Control Panels with LED/LCD Indicators.
Battery-Powered Metering with LCD Readout
The PIC16LF1907-I/P's integrated segmented LCD driver and nanoWatt XLP Sleep current (sub-microamp per Microchip datasheet DS40001853) make it ideal for battery-powered metering such as gas, water, or electricity meters. The 14KB Flash fits the metering firmware plus LCD segment driver library, and 512B RAM supports measurement buffers and calibration constants. With LF (2.5V) operation, a single lithium primary cell can power the meter for over 10 years, while the 40-pin PDIP simplifies through-hole meter-board assembly and IC socket replacement in the field.
Empfohlen
Consumer Appliance Front Panels with LCD
Washing machines, microwaves, and HVAC controls use segmented LCDs to show status, time, and temperature. The PIC16LF1907-I/P drives the LCD glass directly, removing the need for an external LCD driver IC and reducing BOM cost. Its 20 MHz instruction rate handles rotary-encoder scanning, button debouncing, and relay control in real time. The LF voltage range lets the appliance run from a single 3.3V regulator rail, while nanoWatt XLP Sleep drops consumption during standby to under 1uA, helping products meet Energy Star idle budgets.
Empfohlen
Handheld Instrumentation and Testers
Handheld multimeters, cable testers, and field service tools benefit from the PIC16LF1907-I/P's combination of 14KB Flash, 512B RAM, integrated ADC, and LCD segment output. The 40-pin PDIP makes it breadboard-friendly during development, and its nanoWatt XLP Sleep extends battery life between recharges. The LF voltage operation allows direct connection to a single Li-Ion cell (3.0-4.2V) with a low-dropout regulator, and the 20 MHz clock is plenty for ADC-driven measurement averaging and UART-isolated comms to PCs.
Empfohlen
Environmental Sensor Nodes with LCD Display
Wireless or wired environmental sensors (temperature, humidity, CO2) often need a local segmented LCD to show current readings. The PIC16LF1907-I/P wakes from nanoWatt XLP Sleep to take a sensor reading, updates the LCD, and returns to Sleep - all on a coin cell or two AA batteries for years. Its integrated LCD driver avoids a costly external charge-pump IC, and the LF voltage range lets it run directly from depleted cells down to 2.0V. The 40-pin PDIP is useful for low-volume environmental monitoring products that don't justify SMT tooling.
Empfohlen
Remote Controls and Wireless Key Fobs
Battery-powered remote controls and key fobs spend 99% of their life in Sleep, waking only on a button press or timer event. The PIC16LF1907-I/P's nanoWatt XLP Sleep drops quiescent current to sub-microamp, and the 14KB Flash fits rolling-code security algorithms or multi-button IR/RF protocols. The LF voltage range accommodates single CR2032 coin cells, and the segmented LCD option (if used) lets the fob display status icons without an external driver. The 40-pin PDIP is convenient for prototype fobs and low-volume specialty remotes.
Empfohlen
Industrial Control Panels with LED/LCD Indicators
Industrial control panels often have segmented LCDs or LED indicators showing machine status, error codes, and countdowns. The PIC16LF1907-I/P's industrial -40C to +85C rating (the 'I' suffix) lets it operate in factory floor cabinets without thermal derating. Its 20 MHz core handles Modbus RTU over UART, I/O scanning, and fault logging; 14KB Flash stores the protocol stack and application logic; 512B RAM buffers incoming serial frames. The 40-pin PDIP is suitable for panel-mount assemblies and field-replaceable modules.

Wichtigste Unterscheidungsmerkmale
- Integrated segmented LCD driver eliminates external LCD IC (vs. PIC16LF1903-I/P)
- nanoWatt XLP Sleep current for years-long battery life (vs. PIC16F1907-I/P (standard F variant))
- 40-pin PDIP for through-hole prototypes and legacy designs (vs. PIC16LF1907-I/PT (44-TQFP))
Designhinweise
Decouple VDD with a 0.1uF ceramic capacitor placed within 5mm of the VDD pin (pin 1 or pin 19 on the 40-pin PDIP). For battery applications drawing from a single Li-Ion or 2xAA cell, add a 10uF bulk capacitor at the MCU VDD node. The PIC16LF1907's LF voltage range allows operation down to 2.0V typical; verify the specific minimum voltage in the datasheet's electrical characteristics table before committing to a primary-cell design.
Do not confuse the LF (low-voltage) variant with the standard F variant. The PIC16LF1907 operates down to 2.5V nominal with nanoWatt XLP Sleep current, while the PIC16F1907 requires 5V nominal and has higher Sleep current. Substituting a PIC16F1907 for a PIC16LF1907 in a battery design will dramatically shorten battery life. Also ensure MCLR (pin 4 / RA3 or pin 29 / RE3) is pulled high through a 10k resistor if not used, otherwise the device will reset continuously.
Route the ICSP pins RB6 (PGC) and RB7 (PGD) to a 2x3 or 1x6 in-circuit programming header with no series resistors between the header and the MCU pins. Add ESD protection (TVS diodes) on the PGD/PGC lines if the programming header is exposed to user touch. Keep the programming header far from high-current switching nodes (motor drivers, relay coils) to avoid injected noise during debug sessions. Reference the Microchip ICD/PICkit header schematic in the PICkit 3 user guide for the canonical layout.
The PIC16LF1907's on-chip ADC shares analog pins with digital I/O. When using ADC inputs, disable the digital input buffer on those pins (ANSEL register) to prevent digital switching noise from coupling into the ADC sample-and-hold. For segmented LCD outputs, follow the datasheet's bias and contrast configuration; improper bias voltage can cause ghosting or low contrast on the LCD glass. Place the LCD bias capacitors (typically 0.1uF each) close to the LCD bias pins.
Compliance-Informationen
RoHS compliant per Microchip product page. Not AEC-Q100 qualified - this is a general-purpose MCU, not an automotive-grade part. Industrial -40C to +85C temperature range from the 'I' suffix.
