PIC16LF76T-I/ML Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working RAM, peripherals (ADC, timers, communication interfaces), and I/O into one device. The PIC16 family uses a Harvard-architecture RISC CPU with a 14-bit instruction word optimized for deterministic, low-power embedded control. Within the broader taxonomy, this places the PIC16LF76 in the MCU > microcontroller > 8-bit MCU > PIC16 family > PIC16F7x sub-family, sitting alongside 16-bit and 32-bit MCUs in Microchip's embedded portfolio.
Key features include an integrated 8-bit Analog-to-Digital Converter (ADC) with 5 input channels, 25 digital I/O pins, and three serial communication peripherals: I2C (MSSP), SPI (MSSP), and USART. The device also includes two 8-bit timers and one 16-bit timer, a Watchdog Timer, and 256 bytes of EEPROM data memory. The 'LF' prefix designates the wide-voltage 1.8V-3.6V operating range ideal for battery-powered applications.
Architecturally, the PIC16LF76 uses Microchip's mid-range 14-bit instruction set with a single accumulator WREG, a hardware multiplier, and an interrupt controller. Its nanoWatt power management modes provide programmable sleep currents, enabling long battery life in portable products. The integrated brown-out reset and Power-on Reset improve system reliability across unstable supply conditions.
Typical applications include industrial sensor interfaces, low-power remote controls, battery management systems, small home appliances, HVAC controllers, and consumer electronics front panels. The combination of Flash memory, on-chip ADC, and multi-protocol serial interfaces makes it well suited to mixed-signal embedded designs.
When designing with this device, calculate worst-case current draw across all enabled peripherals before committing to battery budgets, and verify that the 1.8V minimum supply meets the ADC reference voltage requirements for the application's accuracy targets.

Typical Applications
PIC16LF76T-I/ML is suitable for 6 applications: Battery-Powered Sensor Interface, Industrial Control Front Panel, Home Appliance Controller, Remote Control / Consumer IR, HVAC Climate Controller, LED Lighting Controller.
Battery-Powered Sensor Interface
The PIC16LF76T-I/ML's 1.8V-3.6V wide operating range and low-power nanoWatt sleep modes make it ideal for 2x AA battery-powered sensor nodes. The 14KB Flash supports small Modbus or custom sensor protocols, while the 5-channel 8-bit ADC handles temperature, humidity, and pressure transducers with adequate resolution for HVAC-grade accuracy. Brown-out reset prevents corruption at end-of-life battery voltage.
Recommended
Industrial Control Front Panel
The PIC16LF76T-I/ML integrates 25 digital I/O lines plus 5 ADC channels in a compact QFN-28 footprint, fitting industrial control panels where PCB space is constrained. Three communication peripherals (I2C, SPI, USART) connect to display drivers, keypads, and supervisory controllers. The -40C to +85C industrial temperature rating supports factory floor deployment without thermal management.
Recommended
Home Appliance Controller
With 14KB Flash supporting full state-machine implementations and 368B RAM for timer/event variables, the PIC16LF76T-I/ML is well suited to white-goods controllers in washing machines, dishwashers, and microwave ovens. The 5-channel ADC reads motor current, temperature sensors, and water level; the USART connects to inverter modules and HMI boards. The industrial -40C to +85C range covers typical appliance environments.
Recommended
Remote Control / Consumer IR
The PIC16LF76T-I/ML's 20MHz clock supports accurate IR carrier frequency generation (typically 38kHz/40kHz) using the CCP module and a simple GPIO for the IR LED driver. The 14KB Flash accommodates complete RC5/RC6/SIRC protocol stacks with learning capability, while 368B RAM buffers received frames. Low-voltage operation extends battery life on coin cells or 2x AAA configurations.
Recommended
HVAC Climate Controller
The PIC16LF76T-I/ML's 5-channel ADC supports simultaneous temperature sensing of supply air, return air, outdoor ambient, and humidity transducers, while 25 I/O lines drive relay controls for fan speeds, compressor, and reversing valves. With 14KB Flash, the device implements full PID control loops for climate regulation. The QFN-28 package fits behind wall-mounted thermostat displays with minimal PCB area.
Recommended
LED Lighting Controller
The PIC16LF76T-I/ML's PWM-driven CCP modules combined with 5 ADC channels for color/temperature feedback enable smart LED driver controllers in architectural lighting. The 14KB Flash stores color profiles, fade curves, and DMX-512 or DALI protocol stacks. The USART communicates with upstream lighting controllers, while the wide 1.8V-3.6V supply operates from a regulated 3.3V rail.

Key Differentiators
- Wide 1.8V-3.6V operating range enables direct battery operation (vs PIC16F76T-I/ML)
- More ADC channels in same QFN-28 footprint (vs PIC16LF722A-I/ML)
- Larger Flash for protocol stacks (vs PIC16LF73T-I/ML)
Design Notes
Estimated: At 20MHz and 3.3V supply, the PIC16LF76T-I/ML active current is approximately 8-10 mA per Microchip datasheet DC characteristics. In sleep mode with WDT disabled, current drops to <1 uA, enabling battery-powered designs. For accurate battery-life modeling, calculate the duty cycle of active vs sleep states and include ADC conversion current (~1 mA during conversion) in active-mode budgets.
The QFN-28 package has an exposed thermal pad that MUST be soldered to the PCB ground plane for proper thermal dissipation and electrical grounding. Use at least 4 thermal vias under the pad to connect to inner ground planes. Place 0.1 uF decoupling capacitors close to VDD (pin 20) and VSS (pin 19), with bulk 10 uF tantalum or ceramic capacitors on each supply rail.
Do not confuse PIC16LF76 (1.8-3.6V) with PIC16F76 (4.0-5.5V) - they share the same datasheet but are NOT electrically drop-in compatible. Also, the 'T' suffix (e.g., PIC16LF76T-I/ML) indicates Tape & Reel packaging, while the absence of 'T' (e.g., PIC16LF76-I/ML) indicates tray; both are functionally identical but require different assembly line setup. Always verify configuration bits at programming time to enable proper oscillator and watchdog operation.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - use AEC-Q100 grade parts for automotive. Lead-free (Pb-free) reflow profile per JEDEC J-STD-020.
