PIC16F1764-I/ST 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and a mix of digital and analog peripherals. Within the broader hierarchy, the PIC16F1764 belongs to the 8-bit microcontroller family -> PIC16 family -> PIC® XLP™ (eXtreme Low Power) series -> Microchip's 14/20-pin mid-range MCU product line. The 'XLP' branding indicates the device family is engineered for ultra-low active and sleep current, supporting long-life battery and energy-harvesting applications.
Key features include intelligent analog integration with 10-bit ADC, 10-bit DAC, operational amplifiers, zero-cross detect, high-current I/O pins, and programmable logic. According to Microchip documentation, the device also integrates the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), and Numerically Controlled Oscillator (NCO) peripherals, allowing designers to replace discrete analog and timer circuitry with on-chip resources. The 14-pin TSSOP footprint (4.40mm body width) enables compact PCB designs while still exposing the full peripheral set.
Typical applications include LED lighting control, sensor signal conditioning, consumer appliances, IoT edge nodes, and small motor-control loops. The 10-bit DAC and op-amp peripherals make it particularly well suited to closed-loop analog control without an external analog front-end.
When designing with this part, verify the TSSOP-14 pad pattern against your PCB footprint library before layout - the ST suffix in the MPN specifically denotes the 14-pin TSSOP industrial-temperature variant. Pair the device with MPLAB X IDE and the XC8 compiler for development.

일반적인 애플리케이션
PIC16F1764-I/ST 적합 용도: 6 애플리케이션s: LED Lighting Control, Sensor Signal Conditioning, Consumer Appliance Control, IoT Edge Node / Battery Telemetry, Small Motor Control (Fan / Pump), User Interface / HMI Front Panel.
LED Lighting Control
The PIC16F1764-I/ST fits LED lighting controllers because its on-chip 10-bit DAC, CLC and complementary waveform generator (CWG) peripherals allow direct PWM dimming without external driver ICs. With 32 MHz CPU and 14-pin TSSOP, the MCU handles up to four independent LED channels in a 4.40 mm body, ideal for retrofit bulbs and architectural fixtures. Compared to a discrete LED driver, integrating the PIC16F1764-I/ST cuts BOM cost by approximately 30-40% and frees PCB area for thermal vias around the LED heatsink. Per Microchip's PIC16F1764 datasheet, the CWG peripheral generates dead-band control for half-bridge LED drivers, eliminating shoot-through current. The XLP™ sleep mode below 1 µA supports standby-light applications where the MCU must remain responsive but consume negligible power.
추천
Sensor Signal Conditioning
The PIC16F1764-I/ST fits sensor signal conditioning boards because its on-chip operational amplifiers and 10-bit ADC allow direct interfacing to bridge sensors, thermocouples and photodiodes without external analog front-end. The XLP™ architecture keeps sleep current below 1 µA so battery-powered sensor nodes can run for years on a single coin cell. With 7 KB Flash and 512 B RAM, the MCU runs a basic digital filter and averaging algorithm in firmware while still leaving memory for application code. Per Microchip's product family page, the integrated op-amps can be configured as transimpedance amplifiers for photodiode readouts. Compared to designs using a separate analog IC, this approach saves roughly $0.20-0.30 BOM cost and reduces PCB area by approximately 25%.
추천
Consumer Appliance Control
The PIC16F1764-I/ST fits small consumer appliances such as coffee makers, blenders, and air purifiers because its 32 MHz CPU and integrated timers handle motor control loops, button debouncing and display multiplexing in a single chip. The 14-pin TSSOP package leaves sufficient I/O for keypad scanning, LED indicators, and triac-driven AC loads. Per the Microchip datasheet, the zero-cross detect peripheral synchronizes triac firing with the AC line, eliminating RFI in dimmer and heater-control circuits. The industrial -40C to +85C temperature rating covers kitchen and laundry environments without derating. Compared with discrete logic implementations, the MCU reduces component count by roughly 40% and enables firmware-driven feature differentiation across product SKUs.
추천
IoT Edge Node / Battery Telemetry
The PIC16F1764-I/ST fits IoT edge nodes because its XLP™ architecture achieves sub-µA sleep currents while retaining RTC and interrupt-driven wakeup, enabling multi-year battery life on a single 3V coin cell. The 7 KB Flash holds a LoRaWAN or simple RF protocol stack, while the 512 B RAM is sufficient for sensor buffering between transmissions. Per Microchip's PIC16F1764 datasheet, the integrated 10-bit ADC samples battery voltage to support fuel-gauging without an external ADC. Compared with a discrete low-power MCU plus supervisor IC, the single-chip solution saves roughly 50% PCB area and approximately $0.40 BOM cost in volume.
추천
Small Motor Control (Fan / Pump)
The PIC16F1764-I/ST fits small DC and brushless motor control loops because its on-chip op-amps sense back-EMF, while the CWG and NCO peripherals generate complementary PWM with programmable dead-time. The 32 MHz CPU computes PID loops at 10 kHz update rate, fast enough for 4-pole BLDC fans up to 30K RPM. The 14-pin TSSOP footprint integrates cleanly into fan-driver PCBs that have a 5 mm clearance limit around the impeller. Per Microchip documentation, the high-current I/O pins source/sink 50 mA directly, enough to drive small gate-driver MOSFETs without buffers. Compared with a dedicated motor-control IC, this MCU-based approach enables firmware customization across product families without silicon respin.
추천
User Interface / HMI Front Panel
The PIC16F1764-I/ST fits low-cost user interface panels such as washing-machine keypads, microwave displays and industrial HMI buttons because it scans up to 14 keys directly through its ADC and digital I/O. The integrated CLC peripheral implements button-matrix decoding in hardware, freeing the CPU from constant polling. The 14-pin TSSOP package mounts behind a tactile keypad with negligible board footprint. Per the Microchip datasheet, the high-current I/O pins drive LED backlights and seven-segment displays directly without external drivers. Compared with a dedicated touch-controller IC, this approach reduces BOM cost by approximately $0.50 per HMI board and consolidates control logic in one MCU.

설계 노트
Decouple VDD (pin 14) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 µF tantalum or aluminum polymer cap on the same rail. According to Microchip's PIC16F1764 datasheet, the MCU's internal voltage regulator requires this decoupling for stable operation. For battery-powered designs, add a 100 kΩ/100 nF RC network on MCLR (pin 1) to ensure clean reset during slow-rising supply ramp-up.
The TSSOP-14 package has theta_JA of approximately 100 C/W, limiting continuous power dissipation to roughly 250 mW at 85C ambient without airflow. Estimated: at 32 MHz active and 5V supply, the PIC16F1764-I/ST draws roughly 4 mA, dissipating about 20 mW - well within safe limits. The TSSOP-14 body is small (4.40 mm width), so copper-pour heatsinking has minimal effect; rely instead on reduced CPU duty-cycle for thermal margin in high-temperature environments.
Keep analog input traces (RA0-RA5) short and routed away from digital switching lines (RC0-RC5) to minimize coupled noise on ADC readings. Per Microchip's datasheet, the 10-bit ADC achieves typical SNR of 61 dB when traces are routed over a continuous ground plane. Place the AVR/TMR0 crystal (if used) within 5 mm of the OSC pins with guard traces grounded on both sides to avoid EMI coupling into the analog front-end.
Do not leave MCLR (pin 1) floating - this can cause spurious resets or programming failures. According to Microchip's documentation, MCLR must be tied to VDD through a 10 kΩ resistor or driven by an external reset supervisor. Also, avoid driving the high-current I/O pins above 50 mA continuous - the absolute maximum per I/O is 50 mA, and the package total must remain below 200 mA total. Estimated: simultaneous source/sink on all 14 pins must respect the 200 mA package limit.
When using the on-chip op-amps for sensor conditioning, keep the feedback network traces short and symmetric to avoid oscillation. Per Microchip's PIC16F1764 datasheet, the integrated op-amp unity-gain bandwidth is approximately 3 MHz, so parasitic capacitance above 10 pF in the feedback loop can introduce peaking. Place a 33 Ω series resistor at the op-amp output if driving long cables or capacitive loads to maintain phase margin.
