PIC16LF767T-I/SO Overview
An 8-bit PIC microcontroller is a Harvard-architecture RISC processor optimized for embedded control. It belongs to the broader category of microcontrollers -> microcontrollers ICs -> microprocessors and controllers -> semiconductors. The PIC16F767 family is the mid-range 8-bit line that pioneered Microchip's nanoWatt technology, which adds multiple power-management modes (Run, Idle, Sleep) and ultra-low-power wake-on-change peripherals. The 28-pin SOIC variant of the PIC16F767 family brings 25 I/O pins, peripherals such as 10-bit ADC, USART, MSSP (SPI/I2C), Capture/Compare/PWM (CCP), and comparators to compact through-hole-friendly surface-mount designs.
Key features include 14KB Flash (8K x 14), 368 bytes SRAM, 256 bytes EEPROM, 25 digital I/O pins, 11 channels of 10-bit ADC, two analog comparators, one USART with LIN capability, one MSSP (SPI/I2C), two CCP modules, and nanoWatt power management with a typical Sleep current under 1uA. The wide 2.0V to 5.5V operating range (LF variant) plus 10 MIPS performance at 10MHz allow flexible power/performance tuning.
Typical applications include industrial sensor conditioning, low-power remote controls, battery-backed instrumentation, LIN slave nodes, and small appliance control. The 28-SOIC footprint also suits hand-solderable prototypes where 0.65mm-pitch QFP is impractical. Designers should review the PIC16F737/767 datasheet for pinout, peripheral mapping, and nanoWatt configuration bit settings.

Typical Applications
PIC16LF767T-I/SO is suitable for 6 applications: Industrial Sensor Conditioning, Low-Power Remote Control, LIN Slave Node in Automotive Body Electronics, Small Appliance Control, Battery-Backed Instrumentation, IoT Sensor Edge Node.
Industrial Sensor Conditioning
The PIC16LF767T-I/SO suits industrial sensor conditioning nodes where its 11-channel 10-bit ADC acquires multiple analog inputs (temperature, pressure, strain) while its nanoWatt Sleep mode drops system current below 1uA between samples. With 14 KB Flash and 368 bytes RAM, the MCU handles linearization, calibration, and HART or 4-20 mA loop framing. The 2.0V to 5.5V operating range lets it run from a single Li-ion cell or 24V loop-derived supply, and the 28-SOIC footprint simplifies conformal-coated assemblies in harsh environments.
Recommended
Low-Power Remote Control
Battery-powered remote controls benefit from the PIC16LF767T-I/SO's nanoWatt Sleep current under 1uA combined with interrupt-on-change I/O for direct keypad or PIR wake-up. Its 10 MHz core delivers 10 MIPS, sufficient to scan a 4x4 matrix keypad, debounce, encrypt the keystroke, and emit via the integrated USART or PWM-driven IR LED. The 2.0V minimum supply extends coin-cell battery life, and the 28-SOIC package supports hand-solderable prototypes for low-volume products.
Recommended
LIN Slave Node in Automotive Body Electronics
The PIC16LF767T-I/SO serves as a cost-effective LIN slave node in body-electronics modules (window lift, mirror adjust, seat control) thanks to its integrated USART with LIN-compatible hardware and 10 MIPS core. The 14 KB Flash accommodates LIN stack and application code, while 368 bytes RAM holds frame buffers. The 25 I/O pins drive relays, LEDs, and H-bridges via the two CCP (PWM) channels, and the 2.0V to 5.5V range tolerates 12V automotive bus transients after external regulation.
Recommended
Small Appliance Control
Small appliances (coffee makers, blenders, fans, slow cookers) use the PIC16LF767T-I/SO to read user inputs from capacitive touch buttons or rotary encoders via the 10-bit ADC and comparators, then drive TRIACs, MOSFETs, or relay coils via PWM/CCP outputs. The 14 KB Flash holds user-interface state machines and EEPROM-stored presets survive power loss. The 28-SOIC package is ideal for hand-repair-friendly designs and the wide 2.0V to 5.5V supply range covers rectified-mains-derived rails.
Recommended
Battery-Backed Instrumentation
Portable meters and data loggers leverage the PIC16LF767T-I/SO's nanoWatt Sleep modes and 2.0V minimum operating voltage to extend battery life during standby. The 11-channel 10-bit ADC scans sensors while 256 bytes EEPROM preserves calibration constants across battery swaps. The 14 KB Flash stores sampling firmware and the MSSP (I2C) talks to an external RTC and EEPROM for time-stamped logging. The 28-SOIC package is robust for handheld enclosures.
Recommended
IoT Sensor Edge Node
Low-bandwidth IoT edge nodes (soil moisture, asset tracking, building automation) pair the PIC16LF767T-I/SO with a sub-GHz or BLE module via the integrated USART. The MCU's nanoWatt Sleep reduces average current to a few uA, while the 14 KB Flash and 368 bytes RAM handle sensor fusion, encryption, and message buffering. The 25 I/O pins drive multi-sensor arrays and the 2.0V to 5.5V range supports direct Li-ion or regulated 3.3V operation with minimal external power components.

Design Notes
PIC16LF767T-I/SO supports nanoWatt Sleep current below 1uA at 2.0V. To minimize Sleep current, disable the ADC module (ADON=0), turn off comparators (CM2:CM0=111), and place all unused I/O pins as outputs driving low. Use the internal LFINTOSC (31 kHz) for Timer1 time base during Sleep so the main oscillator can stay off.
Place a 0.1uF ceramic decoupling capacitor as close as possible to the VDD pin (pin 20), with a second 10uF tantalum or aluminum bulk capacitor nearby. The AVSS (pin 8 and 19) should connect to the analog ground plane, separated from the digital ground and joined only at the VDD return point to avoid digital switching noise coupling into ADC inputs.
Do not drive the MCLR pin low during normal operation; tie it to VDD through a 10 kohm resistor. The MCLR/VPP pin is also the in-circuit serial programming entry, and if it floats, noise can cause unintended resets. When using the internal oscillator, the OSCTUNE register must be left at default for 10 MHz operation, and the OSCCON must be set before switching peripherals that depend on system clock.
When using the 10-bit ADC for accurate measurements, use VREF+ from a low-noise reference (such as the internal 2.048V bandgap or an external MCP1525) and add an RC filter (10 ohm, 0.1uF) at the VREF+ pin. Enable acquisition delay (ACQT) and adequate ADC clock prescale (ADCS) to ensure the sample-and-hold capacitor fully settles - typical 16 TAD gives 11.5 us at 20 MHz Fosc.
