PIC16F1768-E/P 개요
A microcontroller (MCU) is an integrated circuit containing a CPU core, program memory, data RAM, and programmable I/O peripherals on a single chip. Within the broader taxonomy it sits as: 8-bit MCU -> microcontroller -> embedded processor -> IC. The PIC16 family uses Microchip's enhanced mid-range RISC core with a 14-bit instruction word and Harvard architecture, providing deterministic instruction timing at 32MHz (8 MIPS) with extremely low power consumption suitable for battery and energy-harvesting designs.
Key differentiating features of the PIC16F1768 include: 4 x 10-bit ADC channels, 2 x operational amplifiers, zero-cross detect for TRIAC/SCR control, high-current sink/source I/O pins (up to 50mA), 7KB self-programmable FLASH, and an integrated temperature indicator. The device operates from 2.3V to 5.5V with the standard PIC16F176X pinout and includes nanoWatt XLP (eXtreme Low Power) technology with sleep currents below 1 µA typical.
The MCU uses a 14-bit instruction word with 35 standard instructions plus optimized branches, an 8-level hardware stack, and 49 SFRs. Internal peripherals such as the 10-bit ADC, comparators with selectable references, and configurable logic cells allow closed-loop analog control without external circuitry. This makes it well-suited to smart sensor, lighting, and motor-control applications.
Typical applications include LED lighting drivers (constant-current regulation using the integrated op amps), TRIAC-based AC dimming (zero-cross detect), PIR/sensor signal conditioning, battery-powered IoT endpoints, and small motor control loops. The 20-PDIP package is favored for through-hole prototyping, hobbyist platforms, and industrial control modules where socketed replacement is desirable.
When designing, ensure the ICSP/PGD/PGC pins are reserved for in-circuit programming and debug access. Decouple VDD with a 100nF ceramic cap placed within 5mm of the pin, and keep MCLR tied to VDD through a 10kΩ resistor for normal operation. Unused I/O should be configured as outputs low to minimize current draw.

일반적인 애플리케이션
PIC16F1768-E/P 적합 용도: 6 애플리케이션s: LED Lighting Drivers with TRIAC Dimming, PIR Motion Sensor Signal Conditioning, Battery-Powered IoT Sensor Nodes, Small BLDC or Brushed-DC Motor Control, Industrial Process Control Modules, Appliance User Interface and Control.
LED Lighting Drivers with TRIAC Dimming
The PIC16F1768-E/P's two integrated operational amplifiers enable closed-loop constant-current regulation for high-brightness LEDs, while the on-chip zero-cross detect allows direct AC mains sensing for phase-controlled TRIAC dimmer compatibility. With 7KB FLASH and 256 bytes RAM, it can run PID control loops, log fault conditions, and implement thermal foldback without external components. The 10-bit ADC samples the LED string current and base temperature sensor; PWM outputs drive the MOSFET switch. nanoWatt XLP sleep currents below 1 µA support ENERGY STAR standby requirements for connected luminaires and smart bulbs.
추천
PIR Motion Sensor Signal Conditioning
The PIC16F1768-E/P integrates two op amps that can directly amplify the micro-volt output of a passive-infrared (PIR) sensor without external active components, simplifying the analog front end. The 10-bit ADC digitizes the conditioned signal for motion detection, while configurable logic cells (CLC) implement digital filtering to suppress false triggers from noise and RFI. Its 32MHz CPU runs 8 MIPS, sufficient for adaptive thresholding and pulse-counting algorithms. Operating from 2.3V to 5.5V on a single CR2032 or two AA cells, plus extended -40C to +125C support, the MCU is well suited to security, occupancy, and HVAC-zone sensors.
추천
Battery-Powered IoT Sensor Nodes
The PIC16F1768-E/P's nanoWatt XLP technology delivers sub-1 µA sleep currents, allowing years of operation on a single CR2032 coin cell for wireless sensor endpoints. Its EUSART, I2C, and SPI peripherals connect directly to sub-GHz transceivers or BLE modules, while the 10-bit ADC reads battery voltage and environmental sensors. The 20-PDIP package simplifies through-hole prototyping and field-replaceable sensor modules. With 7KB of FLASH and 256 bytes RAM, the part supports basic state machines, periodic wake/sleep scheduling, and lightweight encryption without needing an external RTC.
추천
Small BLDC or Brushed-DC Motor Control
The PIC16F1768-E/P drives small low-voltage brushed DC motors and low-power brushless DC fans through its PWM modules, with the integrated op amps providing current-sense amplification and the 10-bit ADC digitizing back-EMF or shunt voltage. Zero-cross detect and configurable logic cells enable sensorless commutation strategies for small BLDC fans. The 32MHz core (8 MIPS) handles PI loop closure in tens of microseconds, while 50 mA high-current I/O pins can directly switch small logic-level MOSFETs, reducing BOM count.
추천
Industrial Process Control Modules
The PIC16F1768-E/P's extended -40C to +125C operating range, integrated op amps, and 10-bit ADC make it suitable for industrial process loop transmitters, 4-20mA current loop interfaces, and signal-conditioning modules on factory floors. Its robust I/O can drive relays and SSR inputs directly. Modbus RTU over EUSART is easily implemented in the 7KB FLASH for remote sensor nodes communicating with PLCs. The 20-PDIP package withstands vibration and field-serviceable socket replacement in industrial enclosures.
추천
Appliance User Interface and Control
The PIC16F1768-E/P can serve as the user-interface controller in white goods and small appliances, scanning keypads, driving LED indicators and 7-segment displays via PWM and timer peripherals, while offloading main control to a host MCU. Its high-current 50 mA GPIO pins drive relay coils and buzzer transducers directly. With FLASH self-programmability and ICSP support, firmware updates and field calibration are straightforward, and the extended temperature grade supports oven-adjacent or outdoor appliance installations.

설계 노트
Estimated: at 32MHz full activity the PIC16F1768-E/P typically consumes around 6-8 mA at 5V; sleep with nanoWatt XLP drops below 1 µA. Decouple VDD (pin 1) and VSS (pin 20) with a 100nF ceramic capacitor placed within 5mm of the package, plus a bulk 10µF tantalum or aluminum-polymer capacitor for AC-line-connected applications like TRIAC dimmers. The BOR (brown-out reset) is configurable in configuration bits; enable it for AC mains designs to guarantee defined reset behavior across line voltage sags.
Reserve the ICSP pins (RB6/PGD, RB7/PGC, RA0/ICSPDAT, RA1/ICSPCLK, MCLR/RA3) for in-circuit programming access - do not assign them to load-driving functions. The MCLR pin should be tied to VDD through a 10kΩ resistor and a 100nF cap to ground for noise immunity. For the 20-PDIP footprint, leave generous copper pours under the device for thermal relief (even though the MCU itself dissipates little power, surrounding analog circuitry benefits from a stable ground reference).
Estimated: a common mistake is configuring the MCLR pin as a regular GPIO without first disabling the MCLR function in the configuration bits - the part will not start. Another pitfall is leaving unused I/O pins floating; configure them as outputs low to minimize shoot-through current. Watch out for the 14-bit FLASH word size when writing in C: a 7KB program memory holds 4,096 instructions, not 7,168 bytes of 8-bit data. The configuration bits must be set correctly to enable the internal oscillator and disable the watchdog timer if not used.
