PIC16LF767T-I/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory (Flash/ROM), and a mix of analog/digital peripherals on a single die. Within the semiconductor taxonomy, 8-bit MCUs sit below 16-bit and 32-bit devices in computational throughput, but they dominate ultra-low-power, deterministic and cost-sensitive applications. The PIC16F family uses a modified Harvard RISC architecture with a 14-bit instruction word, balancing code density with predictable interrupt latency for real-time control. nanoWatt technology extends sleep-mode current into the microampere range, enabling battery-powered products.
Key features include 14KB self-programmable Flash with ICD, 368-byte RAM, 256-byte EEPROM, an internal 8 MHz oscillator (calibrated to ±1%), 11-channel 10-bit ADC, two analog comparators, hardware USART and synchronous serial port. The 25 I/O pins each source/sink 25 mA, sufficient for direct LED drive and small-signal relays without external drivers. The 20 MHz maximum clock supports instruction-cycle execution in 200 ns, fast enough for brushed DC motor commutation and most sensor-sampling loops.
The PIC16LF767 architecture uses a RISC core with single-cycle instruction execution except for program branches, plus a 16-level hardware stack. The integrated oscillator calibration saves BOM cost, and the nanoWatt sleep modes preserve battery life in standby. Designers benefit from Microchip's MPLAB X IDE ecosystem, which provides free C compilers (XC8), programmer/debugger support (ICD 3/ICD 4/PICkit), and application libraries.
Typical applications include brushed DC motor control in white goods, sensor-hub firmware in HVAC systems, low-power IoT sensor nodes, handheld consumer devices, and small appliance control boards. The wide operating voltage (2.0-5.5 V) makes it suitable for both 3.3 V Li-ion and 5 V USB-powered designs.
When designing, confirm SSOP land-pattern compatibility with the PCB footprint and verify ADC channel mapping against the chosen pinout. The ICSP/ICD programming pins (RB6/RB7) must remain accessible for in-circuit firmware updates. For ultra-low standby current, place the part in sleep mode and wake from interrupt rather than polling.

Typical Applications
PIC16LF767T-I/SS is suitable for 6 applications: Brushed DC Motor Control, HVAC Sensor Hub, Battery-Powered IoT Sensor Node, Consumer Handheld Device Controller, Small Appliance Control Board, Industrial Sensor Interface Module.
Brushed DC Motor Control
The PIC16LF767T-I/SS is well-suited to brushed DC motor control in white goods and small appliances, where its ECCP (Enhanced Capture/Compare/PWM) module delivers 10-bit PWM resolution for smooth speed regulation, and its 25 mA per-pin source/sink drives small DC motors and half-bridge gate signals directly. At 20 MHz Fosc the instruction cycle of 200 ns supports PID control loops at 10 kHz update rates without timing jitter, while the 11-channel 10-bit ADC samples back-EMF and current-sense signals with 19.5 us conversion time for closed-loop torque control. The LF (2.0-5.5 V) supply range accepts 3.3 V Li-ion packs directly, and nanoWatt sleep currents near 1 uA preserve battery life between motor activations. In typical washing-machine pump or fan-control boards, the part replaces mechanical relays and discrete logic, reducing BOM count by 30%.
Recommended
HVAC Sensor Hub
In HVAC sensor-hub designs the PIC16LF767T-I/SS aggregates temperature, humidity and pressure transducer signals through its 11-channel 10-bit ADC, transmitting processed data over USART or SPI to a main controller. The 14 KB flash accommodates Modbus RTU slave firmware plus sensor linearization tables, while 368-byte RAM is sufficient for sample averaging and protocol buffers. Operating from 2.0-5.5 V lets the same PCB accept both 3.3 V and 5 V transducer rails, simplifying inventory. The internal 8 MHz calibrated oscillator eliminates external crystal cost in space-constrained duct-mounted enclosures. nanoWatt sleep mode drops quiescent current below 1 uA, enabling battery-backed thermostat designs with multi-year coin-cell life. Industrial -40C to +85C operation supports outdoor air-handler installations directly.
Recommended
Battery-Powered IoT Sensor Node
The PIC16LF767T-I/SS anchors low-power IoT sensor nodes where 14 KB flash fits LoRaWAN or Sigfox device firmware with sensor drivers, while nanoWatt sleep currents below 1 uA extend battery life to 5-10 years on a single 2400 mAh Li-thionyl pack. The wide 2.0-5.5 V supply range accepts the Li-thionyl 3.6 V output directly without voltage regulation, reducing BOM and quiescent loss. Hardware USART interfaces directly to the popular RN2483 LoRa module, while the MSSP SPI port drives SPI sensors (e.g., accelerometers, environmental sensors). 25 mA per-pin I/O capability drives indicator LEDs and piezo buzzers without driver transistors, simplifying small-form-factor PCB design. The internal 8 MHz oscillator remains accurate to ±1% across voltage and temperature.
Recommended
Consumer Handheld Device Controller
The PIC16LF767T-I/SS serves as the main controller in consumer handheld devices - remote controls, massagers, and personal-care electronics - where 25 digital I/O pins drive segment LCDs, button matrices, haptic feedback motors and IR LEDs without external drivers. Its 14 KB flash supports multi-language UI tables and gesture-recognition state machines, while 368-byte RAM is ample for buffer management. Operating from 2.0-5.5 V accommodates both rechargeable Li-ion (3.7 V nominal) and alkaline (4.5-6 V with internal LDO) supply chains. nanoWatt sleep drops to microampere levels when the device is idle, extending shelf life beyond two years. The integrated ECCP generates audio PWM for piezo buzzers, eliminating dedicated sound-driver ICs.
Recommended
Small Appliance Control Board
The PIC16LF767T-I/SS targets small appliance control boards (coffee makers, kettles, blenders, air purifiers) where its 20 MHz CPU executes PID temperature and motor-speed loops in real time, while 14 KB flash houses menu logic and sensor-fusion routines. Two CCP/ECCP channels drive TRIAC phase-angle control for AC loads up to several hundred watts with zero-cross detection via the analog comparators. The 11-channel ADC reads thermistor, level-sensor and current-sense signals for safety shutoff logic. Industrial -40C to +85C operation survives under-cabinet heat exposure in enclosed appliance chassis. The 28-SSOP package's 5.30 mm body width fits compact control boards while remaining compatible with automated pick-and-place assembly.
Recommended
Industrial Sensor Interface Module
The PIC16LF767T-I/SS bridges industrial 4-20 mA current loops and Modbus RTU networks in PLC I/O expansion modules, where its USART handles RS-485 differential signalling through an external transceiver and its MSSP SPI port drives 24-bit sigma-delta ADCs for precision analog measurement. The 14 KB flash stores Modbus register maps, calibration coefficients and diagnostic logs, while 256-byte EEPROM retains configuration through power cycles. Operating voltage 2.0-5.5 V accommodates both 3.3 V and 5 V analog front-ends. The -40C to +85C industrial temperature range and 25 mA I/O drive capability meet IEC 61000-4 EMC immunity expectations when combined with proper PCB layout. The 28-SSOP package fits 35 mm DIN-rail module enclosures.

Key Differentiators
- Calibrated internal 8 MHz oscillator eliminates external crystal (vs PIC16F876A-I/SP (legacy 28-SPDIP))
- Low-voltage (2.0-5.5 V) operation with nanoWatt technology (vs PIC16F767-I/SS (standard 4.0-5.5 V F variant))
- Enhanced ECCP module with auto-shutdown and dead-band control (vs PIC16F88-I/P (18-pin legacy variant))
Design Notes
The PIC16LF767T-I/SS accepts 2.0 V to 5.5 V VDD directly. Place a 100 nF decoupling capacitor within 5 mm of pins 11 (VDD) and 12 (VSS), plus a 10 uF bulk capacitor on the supply rail. For battery-powered designs drawing peak loads of 25 mA per pin, ensure the source impedance stays below 1 ohm at switching frequencies to avoid VDD droop causing brown-out resets. The on-chip brown-out reset (BOR) is configurable via configuration fuses to trip at 2.0-4.5 V thresholds.
The 28-SSOP package has 0.65 mm pin pitch and 5.30 mm body width. Use a 4-layer PCB with continuous ground plane beneath the part for EMI suppression, especially when the ADC is sampling low-level analog signals. Route the analog signals (AN0-AN8) on a separate analog layer segment with ground isolation, and keep digital switching traces (PWM outputs, USART, SPI clock) at least 5 mm away from analog traces. Place a guard ring around the analog reference pins (RA2/VREF-, RA3/VREF+) tied to ground.
Do not leave the MCLR pin (pin 1) floating - tie it to VDD through a 10 kohm pull-up resistor, or the part will reset intermittently. The ICSP programming pins RB6/PGC and RB7/PGD (pins 27 and 28) must be accessible; do not place series resistors above 470 ohm on these pins or in-circuit programming will fail. The internal 8 MHz oscillator is factory calibrated but may shift over temperature; for time-critical protocols (UART, SPI master) consider using an external crystal. The ADC's maximum source impedance is 2.5 kohm for rated 10-bit accuracy - use buffer op-amps for higher-impedance sources.
Compliance Information
RoHS and REACH compliant per Microchip product declaration. Industrial temperature grade -40C to +85C; not AEC-Q100 qualified (choose automotive-graded PIC16 variants for AEC-Q100 designs). Lead-free matte-tin plating on SSOP leads.
