PIC16F1764T-I/SL Overview
An 8-bit microcontroller (MCU) is a small computing system on a single integrated circuit containing a CPU, program memory (Flash), data memory (RAM/EEPROM), and configurable I/O peripherals. The PIC16F1764T belongs to the PIC16 family of mid-range microcontrollers from Microchip, which sits within the broader 8-bit MCU category alongside AVR and 8051 architectures, targeting cost-sensitive and power-constrained designs. Modern PIC16 devices integrate traditional digital I/O with programmable analog blocks, allowing designers to replace discrete op-amps, comparators, and DACs with on-chip resources.
Key features include up to 12 channels of 10-bit ADC, a 10-bit DAC with internal references, two operational amplifiers, a zero-cross detect module for TRIAC/SSR control, four 16-bit PWM modules with complementary outputs, four configurable logic cells (CLC), high-current I/O pins capable of sourcing/sinking up to 50 mA, and the enhanced Mid-Range 16-bit instruction set. XLP sleep currents below 100 nA (typical) enable multi-year battery life in IoT sensor nodes.
Architecturally, the PIC16F1764T uses the enhanced mid-range core (16-bit instruction width, 8-bit data path) with a single-cycle hardware multiplier. Internal configurable logic cells (CLC) allow hardware-level combinational/sequential logic independent of CPU execution, offloading tasks such as waveform generation and event sequencing. The integrated op amps and DAC enable closed-loop analog control without external analog ICs.
Typical applications include LED lighting drivers (constant-current regulation via op-amp + DAC), TRIAC/SSR dimmer control (zero-cross detect + PWM), small appliance control (coffee machines, fans), battery-powered IoT sensor nodes, smart metering front ends, and sensor signal conditioning with on-chip amplification. The 14-SOIC footprint keeps the BOM compact and the PCB area minimal.
When designing with this device, allocate careful attention to analog supply decoupling - separate AVDD/AVSS from VDD/VSS with ferrite beads and 100 nF + 10 uF local caps to preserve the ADC and DAC accuracy. Configure unused I/O as outputs low to minimize sleep current, and use the CLC modules to offload time-critical tasks from the CPU, freeing MIPS for application logic.

Typical Applications
PIC16F1764T-I/SL is suitable for 6 applications: TRIAC/SSR Phase-Cut Dimmer Control, Constant-Current LED Lighting Driver, Battery-Powered IoT Sensor Node, Small Appliance Control (Coffee Machine / Fan / Mixer), Smart Meter Front-End / Sensor Signal Conditioning, Hobby and Education: PIC Development Platform.
TRIAC/SSR Phase-Cut Dimmer Control
The PIC16F1764T-I/SL is exceptionally well suited to phase-cut AC dimmers thanks to its integrated zero-cross detect (ZCD) module and four 16-bit PWM modules with complementary outputs. The ZCD senses the AC line zero crossings, the firmware computes the firing angle, and a PWM/CCP module drives the TRIAC gate via an optocoupler. The 10-bit DAC and on-chip op amp allow closed-loop current sensing for constant-current LED fixtures. Operating from 1.8 V to 5.5 V lets the same MCU drive both 3.3 V logic and 5 V gate-driver circuits, and the 14-SOIC footprint keeps the BOM compact inside the wall-plate enclosure.
Recommended
Constant-Current LED Lighting Driver
For constant-current LED drivers the PIC16F1764T-I/SL combines a 10-bit DAC (current setpoint), two on-chip op amps (sense amplifier + error amplifier), four 16-bit PWMs (MOSFET gate drive), and CLC blocks (hardware PWM blanking/blanking-time compensation). A typical buck topology uses one op amp as a current-sense amplifier and the second as an error integrator; the DAC programs the setpoint and the PWM drives the high-side MOSFET. XLP sleep currents below 1 uA enable standby-mode efficiency that meets Energy Star criteria. The 32 MHz CPU and single-cycle hardware multiplier handle CIE-1931 dimming curves and thermal foldback in real time without external DSP.
Recommended
Battery-Powered IoT Sensor Node
The PIC16F1764T-I/SL's eXtreme Low Power (XLP) technology - sleep currents under 100 nA typical, wake-up from sleep via interrupt on change, ADC, or timer - makes it ideal for multi-year-battery sensor nodes measuring temperature, humidity, or contact closure. The 10-bit ADC with internal voltage reference eliminates the need for an external reference IC, and the on-chip op amp conditions a thermistor or Wheatstone-bridge sensor directly. The 14-SOIC package, 7 KB Flash, and 512 B RAM support custom Modbus/RTU or LoRaWAN-node firmware while keeping the bill of materials under $1.50.
Recommended
Small Appliance Control (Coffee Machine / Fan / Mixer)
Small appliances benefit from the PIC16F1764T-I/SL's combination of high-current I/O (source/sink up to 50 mA - drives relays directly), four 16-bit PWMs (motor speed control or heating element PWM), the 10-bit ADC (NTC temperature sensing), and the 10-bit DAC (setpoint programming). The zero-cross detect module synchronizes TRIAC-based heater control for coffee machines, while the CLC offloads time-critical switching from the CPU. Industrial -40C to +85C temperature rating ensures reliability in kitchen and garage environments.
Recommended
Smart Meter Front-End / Sensor Signal Conditioning
The integrated two op amps and 10-bit ADC of the PIC16F1764T-I/SL enable direct conditioning of low-level analog signals from current transformers, shunt resistors, or piezoelectric sensors without external analog ICs. The DAC can generate calibration references, and the CLC modules implement digital filters or window comparators in hardware. The 32 MHz CPU computes RMS, peak, and harmonic content in real time. The 14-SOIC industrial temperature grade withstands metering equipment environmental stress (-40C to +85C).
Recommended
Hobby and Education: PIC Development Platform
With 7 KB Flash, 512 B RAM, 14 I/O pins, and a 14-SOIC breadboard-friendly footprint (with breakout adapter), the PIC16F1764T-I/SL serves as an ideal educational platform for learning PIC assembly and C programming. MPLAB X IDE, XC8 compiler, and PICkit 4 debugger/programmer provide a free and complete toolchain. The 10-bit ADC, DAC, op amps, PWM, and CLC blocks cover most teaching lab experiments in a single chip. Industrial temperature grade allows outdoor and lab-bench robustness.

Design Notes
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 7) and another 100 nF near AVDD (if separate analog supply is used). Add a bulk 10 uF tantalum or aluminum-polymer capacitor on the main VDD rail within 1 cm of the MCU. For battery applications, route the MCU VDD through a ferrite bead fed from the battery to isolate digital switching noise from sensitive analog rails.
Keep the ICSPDAT/ICSPCLK traces (shared with RB7/RB6) short and away from switching nodes to prevent programming/debugging glitches. If using an external crystal on RA6/RA7, place the crystal within 5 mm of the pins and surround it with a ground guard ring to minimize EMI. The MCLR pin (pin 3) requires a 10 kohm pull-up to VDD and a 100 nF cap to ground for proper reset behavior during power-up and brown-out events.
Do not leave unused I/O pins floating - configure them as outputs driving low to eliminate parasitic current draw (can exceed 1 mA per pin in floating state). The ZCD module requires a current-limiting series resistor (typically 1 Mohm) at its input to protect the pin from line-voltage transients. Always program the BOR (brown-out reset) to a voltage below your minimum operating voltage to prevent unintended reset during normal operation.
When using the 10-bit ADC with internal voltage reference, place a 10 uF + 100 nF capacitor pair on the VREF+ pin if it is brought out, or ensure the internal reference settling time (typically 10-50 us) is respected before initiating conversions. For op-amp circuits, add a 10 pF to 100 pF feedback capacitor to prevent oscillation in unity-gain or high-impedance configurations. Verify op-amp output stability under all load conditions specified in the datasheet.
Estimated: At maximum CPU activity (32 MHz, all peripherals active, all I/O toggling), the PIC16F1764T-I/SL draws approximately 8 mA from 5 V, dissipating roughly 40 mW. The 14-SOIC thermal resistance (theta_JA) is approximately 100 C/W, yielding a junction temperature rise of 4 C above ambient - well within the -40C to +85C industrial rating. No heatsinking required for typical applications.
