PIC16LF1769-I/SS Übersicht
An 8-bit microcontroller is a small, self-contained computer-on-a-chip built around a byte-wide data path, ROM/RAM, timers, ADC and digital peripherals. It belongs to the broader hierarchy of microcontroller -> embedded controller -> semiconductor IC. The PIC16F/LF176x family specifically targets applications that combine intelligent analog (10-bit ADC, op amps, zero-cross detect) with conventional digital I/O, eliminating the need for several external analog ICs in cost-sensitive and space-constrained products.
Key features of the PIC16LF1769-I/SS include 18 general-purpose I/O pins, a 10-bit A/D converter with multiple channels, configurable op-amp peripherals, high-current I/O capable of sourcing/sinking higher LED drive, an enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), MSSP for SPI/I2C, multiple timers, and the nanoWatt XLP sleep mode. The integrated analog peripherals are the family’s primary differentiator: they reduce BOM cost by removing external op-amps and comparators from many sensor and signal-conditioning designs.
The device is fabricated on a CMOS process and uses Microchip’s enhanced mid-range 8-bit core with a hardware multiplier and a 14-bit instruction word. Operating at 1.8V to 3.6V and industrial temperature range (-40°C to +85°C), the LF1769 targets battery and energy-harvesting applications where the XLP technology provides deep-sleep currents below 1 µA while retaining RAM and peripheral state for instant wake-up.
Typical applications include LED lighting controllers, sensor signal conditioning, low-power IoT nodes, smart thermostats, remote controls, battery chargers, and small motor or fan controllers. The combination of 14KB Flash, 1KB RAM, and integrated op-amps makes it well suited to designs that previously required a microcontroller plus one or two external analog ICs.
When designing with the PIC16LF1769-I/SS, ensure the supply stays within the 1.8V–3.6V LF window, use decoupling capacitors close to VDD, and reserve I/O pins that share analog channels if the on-chip op-amps and ADC are used concurrently. Always validate the specific SSOP-20 pinout against the target board layout and the latest Microchip datasheet, as some package variants differ in I/O count.

LED Lighting Controller and Driver
LED lighting designs benefit from the PIC16LF1769-I/SS's high-current I/O pins, integrated op-amps and 10-bit ADC. The high-current I/O can source/sink LEDs directly, eliminating driver transistors in low- to mid-power fixtures. The op-amp peripherals close the loop on current sensing or photodiode feedback for constant-lumen or daylight-harvesting control, while the 10-bit ADC monitors supply and LED current. PWM-capable timers drive dimming and color-temperature mixing with smooth 10-bit resolution. The 1.8V to 3.6V supply lets the MCU run directly from a single-cell lithium or two-AA battery in portable lighting. Industrial temperature grade (-40C to +85C) supports outdoor and automotive-interior lighting where ambient swings are wide.

Remote Control and Human-Interface Device
The PIC16LF1769-I/SS fits battery-powered remote controls, key fobs and small HMI boards where low standby current, integrated op-amps and small footprint matter most. The op-amps condition capacitive-touch or piezo-electric inputs without dedicated touch ICs, while high-current I/O can drive status LEDs and IR emitters directly. The 1.8V to 3.6V supply lets the device run from a CR2032 coin cell for years thanks to XLP sleep modes. The 14KB Flash holds IR protocol stacks (RC5, NEC, SIRC) or BLE HCI command firmware. The 20-pin SSOP package is hand-solderable for prototypes while still meeting volume-production SMT requirements.
Empfohlen
Small Motor and Fan Controller
Small DC, stepper or BLDC motor and fan controllers use the PIC16LF1769-I/SS as the low-cost digital brain with integrated analog feedback. The op-amps implement back-EMF sensing, current sensing and overcurrent protection; the 10-bit ADC reads tachometer, supply and temperature; and the zero-cross detect simplifies AC-line-commutated control. PWM timers generate drive waveforms up to the 32MHz peripheral clock, while high-current I/O sink/source gates for low-side drivers or small FETs directly. The 14KB Flash accommodates sensorless commutation algorithms, and the 1.8V to 3.6V range allows direct operation from 2x AA or single-cell Li-Ion packs. Industrial temperature grade handles under-hood and outdoor-fan environments.
Empfohlen
Energy-Harvesting Wireless Switch
Energy-harvesting wireless light switches, door sensors and asset trackers leverage the PIC16LF1769-I/SS's deep-sleep currents under 1 uA and instant wake-up from retained RAM/peripheral state.

Wichtigste Unterscheidungsmerkmale
- Lowest supply voltage in the 20-SSOP PIC16F176x family (vs. PIC16F1769-I/SS)
- Integrated op-amps remove external analog ICs (vs. PIC16LF1768-I/SS)
- Extended-temperature option with same die (vs. PIC16LF1769-I/SS (industrial))
Designhinweise
Estimated: at VDD=3.3V and CPU=32MHz active, the LF1769 typically draws ~2 mA. In deep sleep with peripherals disabled, XLP modes drop quiescent current below 1 uA. Place a 100 nF decoupling capacitor within 3 mm of each VDD pin and a bulk 10 uF near the MCU. For battery-only designs, disable unused peripherals via firmware before sleep and use the ADC's internal voltage reference to keep the BOM small.
Route ICSPCLK/ICSPDAT (RB6/RB7) traces as short as possible to a 6-pin ICSP header so firmware can be updated in-circuit. Keep analog traces (ANx pins) away from RB6/RB7 switching and PWM outputs to avoid ADC coupling. The 20-pin SSOP (0.65 mm pitch) is hand-solderable but requires a fine-tip iron; for volume production use a stencil and reflow profile consistent with JEDEC J-STD-020 for MSL 1 packages.
Do not power the LF1769 from a 5V rail - the LF supply window is 1.8V to 3.6V, and exceeding 3.6V will damage the part. For 5V systems, use PIC16F1769-I/SS or place a 3.3V regulator upstream. Watch analog-pin function conflicts: when the on-chip op-amps are enabled, the corresponding ANx pins are reclaimed by the op-amp outputs. Finally, verify the configuration bits in code to enable the internal oscillator before relying on timing-critical peripherals.
