MPN： PIC16LF1768T-I/SS ✓ 啟用中PIC16LF1768T-I/SS 概覽
An 8-bit microcontroller (MCU) is a compact, single-chip computer integrating a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (ADC, timers, communication ports) on one CMOS die. Within the broader semiconductor taxonomy, the PIC16LF1768 belongs to the mid-range PIC16 family, which itself is a sub-family of Microchip's PIC® 8-bit MCU portfolio, sitting beneath the PIC18/PIC24 and dsPIC® families in capability but above the PIC10/PIC12 baseline devices. The "LF" device class is engineered for ultra-low-power operation (sub-uA sleep currents) typically found in IoT, wearable, and remote-sensor designs.
Key features of the PIC16LF1768 include a 10-bit ADC with up to 17 channels, two operational amplifiers, a zero-cross detect module, high-current I/O pins capable of source/sink drive beyond standard GPIO limits, and Peripheral Pin Select (PPS) for flexible signal routing. The device also integrates multiple 16-bit timers, a configurable logic cell, and Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) plus two SPI/I2C capable MSSP modules for serial communication. The eXtreme Low-Power (XLP) architecture supports nanoWatt XLP technology with typical sleep currents measured in the nanoampere range, enabling years of operation from a single coin cell.
Built on a CMOS process with Microchip's enhanced mid-range 8-bit core, the PIC16LF1768 executes most instructions in a single instruction cycle (4 oscillator clocks), yielding an effective 8 MIPS throughput at 32 MHz. The Harvard architecture with separate program and data buses eliminates fetch bottlenecks, while the 14-bit wide instruction word provides a dense instruction set for code-efficient C and assembly development in MPLAB X IDE with the XC8 compiler.
Typical applications include IoT end-node sensor platforms, battery-powered metering and utility monitoring, LED lighting control with dimming feedback loops, capacitive-touch human-interface panels, low-power wireless sensor nodes paired with transceivers, and small motor-control loops using the integrated op-amps for current sensing. The combination of intelligent analog and digital peripherals makes the PIC16LF1768 particularly suited to mixed-signal embedded designs.
When designing with this device, choose the LF variant whenever extended sleep current or wider operating voltage (1.8V-3.6V) matters; the standard PIC16F1768 (without LF) supports higher Vdd up to 5.5V at the cost of higher active current. For footprint compatibility across product variants, the same 20-pin SSOP land pattern accepts the PIC16LF1764/1765/1768/1769 family siblings, allowing PCB reuse when scaling memory or peripheral needs.

The PIC16LF1768T-I/SS is ideal for IoT sensor end-nodes where its nanoWatt XLP technology and 1.8V-3.6V wide-Vdd operation enable years of battery life. The device delivers sub-microampere sleep current per the datasheet, allowing duty-cycled sensor wake/sleep cycles on coin-cell or 2xAA batteries.

推薦
Battery-Powered Utility Metering
For battery-powered gas, water, or electric metering designs the PIC16LF1768T-I/SS provides the right combination of integrated op-amps for current shunt sensing, zero-cross detect for AC line synchronization, and XLP low-power operation. The 10-bit ADC with up to 17 channels handles multiple sensor inputs without external multiplexer, while the 20-pin SSOP footprint keeps meter PCBs compact. Its 1.8V-3.6V range supports direct Li-Ion battery connection.
推薦
LED Lighting Control with Dimming
The PIC16LF1768T-I/SS suits LED lighting controllers with analog or phase-cut dimming thanks to its zero-cross detect module, on-chip op-amps for current feedback, and 10-bit ADC for dimmer signal decoding. The PWM outputs drive MOSFET gate drivers for high-current LED strings, while the 32 MHz core supports real-time dimming algorithms. The 1.8V-3.6V operation works from rectified mains-derived auxiliary rails typical in dimmable fixtures.
推薦
Capacitive-Touch Human Interface Panels
For capacitive touch buttons, sliders, and proximity panels the PIC16LF1768T-I/SS combines the mTouch capacitive sensing peripheral with its 10-bit ADC and integrated op-amps for noise-robust sensing. The 32 MHz core runs Microchip's mTouch sensing library with minimal firmware overhead, while the XLP sleep modes keep standby power negligible for battery-powered remotes. The 20-pin SSOP supports up to 17 touch channels simultaneously.
推薦
Small Motor Control Loops
For closed-loop brushed DC or stepper motor control in compact appliances, the PIC16LF1768T-I/SS integrates the op-amps needed for current shunt amplification, the 10-bit ADC for back-EMF and current feedback, and PWM outputs for H-bridge gate control. Its 8 MIPS throughput handles trapezoidal commutation for small BLDC motors, and the 1.8V-3.6V range suits 2-cell Li-Ion or 3-cell NiMH battery packs common in portable tools.
推薦
Remote Sensor / Environmental Monitoring
For remote environmental monitoring stations (weather, agricultural, industrial) the PIC16LF1768T-I/SS offers multi-channel 10-bit ADC to read temperature, humidity, soil moisture, and gas sensors through I2C/SPI interfaces. The EUSART plus dual MSSP modules allow daisy-chaining sensors and connecting LoRa or sub-GHz transceivers for long-range backhaul. XLP nanoWatt sleep operation stretches battery life to multi-year deployments in solar-augmented remote sites.
推薦
Industrial Sensor Conditioning
In industrial 4-20 mA loop-powered sensor transmitters the PIC16LF1768T-I/SS operates directly from loop current thanks to its wide 1.8V-3.6V range, eliminating the need for separate power conditioning. Its on-chip op-amps condition bridge sensor outputs, the 10-bit ADC digitizes the result, and the EUSART drives HART or RS-485 modems. The -40C to +85C industrial temperature rating supports factory-floor deployment per the device's "-I" suffix.
推薦
Wearable Health Devices
For wearable health and fitness devices the PIC16LF1768T-I/SS combines the XLP ultra-low-power architecture with the compact 20-pin SSOP package to fit small form factors. Its 10-bit ADC reads heart-rate, SpO2, and motion sensor data through I2C, while sleep currents in the nanoampere range extend battery life. The 32 MHz core performs on-device signal processing for step counting or simple heart-rate variability algorithms before transmission to a host phone.

設計說明
When using the PIC16LF1768T-I/SS for battery-powered designs, leverage the nanoWatt XLP sleep modes (Sleep, Idle, and Doze) to achieve typical sleep currents in the nanoampere range per datasheet 40001800B. Configure unused peripherals to off-state via the PMD (Peripheral Module Disable) registers before entering sleep. Estimated: at 3.0V supply with WDT off and full SRAM retention, sleep current is approximately 30-50 nA per the XLP family datasheet.
Place the 0.1 uF Vdd decoupling capacitor within 5 mm of the VDD pin (pin 20) with a wide ground trace to VSS (pin 19). For ADC accuracy, add a 10 uF bulk capacitor plus a separate 0.1 uF ceramic on the analog Vdd rail if your design splits analog and digital supply domains. The 20-pin SSOP exposed-pad variants do not exist for this part - thermal dissipation is through the standard SSOP lead frame.
Do not assume 5V tolerance on I/O pins - the LF variant's absolute maximum Vdd is 3.6V per the datasheet. Applying 5V signals to any I/O pin with the device unpowered can cause latch-up via the ESD protection diodes. Level-shift any external 5V signals with a resistor divider or proper level translator. The configuration words must be set correctly for oscillator selection or the device will fail to start.
For sensitive analog measurements using the on-chip 10-bit ADC, route analog signals (ANx pins) away from PWM and switching traces on the PCB. Use a ground pour under the device with a single-point connection to digital ground at the VSS pin. The zero-cross detect input should be AC-coupled through a high-value resistor divider to limit voltage stress on the input pin within the Vdd range.
