PIC16LF1769-E/SO - 32MHz 8-Bit MCU, 14KB Flash, 20-SOIC | Microchip
MPN: PIC16LF1769-E/SO ✓ Hoạt độngPIC16LF1769-E/SO Tóm tắt
An 8-bit PIC microcontroller is a RISC (Reduced Instruction Set Computer) device that executes a compact, fixed instruction set in a single clock cycle (excluding branches), enabling high throughput from a low-power core. PIC16 MCUs sit in the broader hierarchy: microcontroller -> 8-bit MCU -> RISC processor -> embedded computing. The 'LF' prefix denotes the low-voltage (1.8V-3.6V) variant; the 'F' in PIC16F1769 denotes Flash program memory; the trailing 'E' indicates an extended operating temperature grade of -40C to +125C.
Key features include 14KB Flash, 1KB SRAM, 128B data EEPROM, 18 I/O pins with 100mA sink/source capability, peripheral pin select (PPS) for flexible signal routing, 2x op-amps suitable for analog signal conditioning, zero-cross detect (ZCD) for AC line sensing, configurable logic cells (CLC) for hardware state-machine logic, programmable ramp generators (PRG), and high-resolution 16-bit PWMs ideal for LED lighting, motor control, and power conversion. The integrated 10-bit ADC and DAC support mixed-signal designs without external converters.
The PIC16LF1769 uses the enhanced mid-range 8-bit PIC core with a 14-bit instruction word, a hardware multiplier, and the MIPS-based architectural simplicity that has made PIC MCUs a staple in cost-sensitive and ultra-low-power designs. The XLP™ (eXtreme Low Power) designation delivers nanoWatt sleep currents (<50 nA typical in deep sleep), enabling years of operation from a single coin cell.
Typical applications include LED lighting drivers (16-bit PWM and CLCs for dimming control), battery-powered sensor nodes (XLP nanoWatt standby), consumer appliance control (op-amps + zero-cross detect for triac/triac-driver interfaces), industrial sensor signal conditioning (integrated op-amp + 10-bit ADC), and small motor control (PWM + PRG for current profiling). The 20-SOIC package allows hand-solder-friendly prototyping for low-density designs and is widely supported by PICkit™ programmers and MPLAB® X IDE.
When designing with this part, note that the 'E' suffix indicates -40C to +125C industrial/automotive temperature range; choose the 'I' (-40C to +85C) variant for cost-sensitive commercial applications. The 20-SOIC package has 18 usable I/O (after power and ground pins), and the PPS feature requires careful pin-mapping configuration in MPLAB X IDE via the MCC code configurator.

Ứng dụng tiêu biểu
PIC16LF1769-E/SO phù hợp cho 7 Áp dụngs: LED Lighting Drivers, Battery-Powered IoT Sensor Nodes, White Goods Appliance Control, Industrial Sensor Signal Conditioning, Small Motor Control (BLDC / Stepper), Consumer Electronics Touch Interfaces, Automotive Body Electronics (Non-Safety).
LED Lighting Drivers
The PIC16LF1769-E/SO is well suited to constant-current LED driver designs. Its 2x 16-bit PWM modules deliver fine-grained dimming resolution (down to 16-bit duty cycle), while the integrated op-amps close the current-sense loop directly without external amplifiers. The ZCD module synchronizes PWM phase to AC line crossings for triac-dimmable offline drivers. PPS routes any PWM or op-amp output to any of the 18 I/O pins, simplifying PCB layout for multi-channel luminaires. At 1.8V-3.6V VDD, the MCU runs from the same low-voltage rail that supplies the LED string driver, reducing overall BOM. The -40C to +125C extended temperature grade supports sealed outdoor luminaire housings without derating.

Battery-Powered IoT Sensor Nodes
The PIC16LF1769-E/SO delivers years of battery life in wireless sensor nodes thanks to its XLP™ eXtreme Low Power architecture with <50 nA typical deep-sleep current. The 1.8V minimum VDD allows direct operation from a single CR2032 coin cell (3.0V nominal), eliminating boost converters. The integrated 10-bit ADC and 2 on-chip op-amps interface directly to sensors (temperature, pressure, light) without external analog front-end ICs. Peripheral pin select (PPS) lets the UART, SPI, or I2C peripheral wake the MCU from sleep on incoming data, enabling event-driven designs that only power the radio during active transmit windows. 14KB Flash accommodates small wireless protocol stacks and Over-The-Air update bootloaders.

White Goods Appliance Control
The PIC16LF1769-E/SO fits perfectly into washing machines, dishwashers, and refrigerator controllers where mixed-signal integration simplifies the BOM. Its 2 on-chip op-amps drive thermistor signal conditioning directly, the 10-bit ADC reads NTC temperature probes for safe motor/element control, and the ZCD module synchronizes triac firing to AC line zero crossings for quiet relay and dimmer operation. The 16-bit PWM channels drive BLDC motors or proportional valves without needing an external motor-control IC. The -40C to +125C extended temperature grade tolerates the enclosed, motor-heated appliance environment. PIC16 long-term availability (15+ years) reduces end-product lifecycle risk.

Industrial Sensor Signal Conditioning
In industrial 4-20mA loop transmitters and bridge sensor interfaces, the PIC16LF1769-E/SO provides a tightly integrated analog front end. Its 2 internal op-amps drive the instrumentation amplifier for strain-gauge or load-cell bridges, while the 10-bit ADC digitizes the conditioned output. The 10-bit DAC generates the 4-20mA loop current directly via a current-output op-amp, eliminating a dedicated DAC IC. PPS reassigns the UART peripheral to any spare pin, enabling single-wire debug or isolated RS-485 interfaces. The -40C to +125C extended temperature grade handles factory-floor thermal extremes without additional heatsinking.

Small Motor Control (BLDC / Stepper)
The PIC16LF1769-E/SO drives small brushless DC or stepper motors in pumps, fans, and valve actuators using its 16-bit PWM modules, programmable ramp generators (PRG), and ZCD module. The PRG produces trapezoidal or s-curve acceleration profiles in hardware without CPU intervention, freeing the core for supervisory tasks. The on-chip op-amps condition Hall-sensor or back-EMF signals directly. The 14KB Flash accommodates sensorless or sensored BLDC control algorithms. PPS routes PWM and timer outputs to whichever physical pins match the H-bridge driver layout, simplifying PCB routing and enabling hardware reuse across motor variants.

Consumer Electronics Touch Interfaces
The PIC16LF1769-E/SO supports capacitive touch button and slider interfaces via its CLC (configurable logic cells) and CTMU (charge time measurement unit) peripherals, eliminating dedicated touch ICs. The 18 I/O pins can host up to 17 touch electrodes, suitable for multi-button appliances and small control panels. The 10-bit ADC reads the touch response, while the CLCs implement state-machine logic for gesture detection without CPU load. The XLP nanoWatt sleep current lets battery-powered remote controls sleep for years between user interactions. The 20-SOIC package fits behind the panel and hand-solders easily during low-volume prototype runs.

Automotive Body Electronics (Non-Safety)
The PIC16LF1769-E/SO serves non-safety automotive body electronics like interior lighting, seat controllers, and HVAC blend-door actuators. Its -40C to +125C extended temperature grade handles the automotive under-dash and door-module environment. The integrated op-amps and 10-bit ADC simplify sensor reading for thermistor-based temperature or potentiometer-based position sensing. The 100mA high-current I/Os can directly drive small relays and LEDs without external drivers. For safety-critical automotive applications, however, designers should select the AEC-Q100-qualified PIC16LF1769-E/SO-Q1 variant specifically, which is a separately qualified part number.

Ghi chú thiết kế
The PIC16LF1769-E/SO requires a bulk decoupling capacitor (typically 10uF) close to the VDD pin (pin 1) plus a 0.1uF ceramic bypass cap. For battery-powered designs operating in deep-sleep XLP mode, ensure the VDD rail is stable by adding a 1M-ohm pull-down to the MCLR/VPP pin (pin 1) to prevent inadvertent wake-ups. Estimated: at 32MHz full activity, the LF variant draws approximately 4 mA; in deep sleep with WDT disabled it falls below 50 nA - per Microchip PIC16LF1769 datasheet DS40001775B typical characteristics.
Place a 0.1uF decoupling capacitor within 5mm of the VDD pin and a bulk capacitor (1uF-10uF) on the same rail. Route the ICSP clock/data lines (RA1/ICSPCLK and RA0/ICSPDAT) to a 5-pin programming header so the PICkit 3 or MPLAB ICD can attach in-circuit. Keep analog traces (to the ADC input pins RA0-RA5, RC0-RC2) short and guarded with ground traces to minimize crosstalk from PWM or digital switching signals.
Do NOT exceed 3.6V on VDD for the LF variant - this is the most common failure mode when migrating from F-grade parts. The PPS feature requires explicit unlock sequence in code; without the UNLOCK PPSLOCK register sequence, peripherals cannot be remapped. The 10-bit ADC requires the FVR (Fixed Voltage Reference) module to be enabled if using an internal reference above 2.048V; otherwise use VDD as the reference.
Estimated: at 32MHz full CPU activity, the 20-SOIC package dissipates approximately 60-80 mW with 3.3V VDD and 24 mA active current - well within the package thermal limits. The package theta_JA is approximately 80 C/W on a standard 2-layer 1oz PCB, allowing roughly 1.25 W dissipation before reaching 125C junction at 25C ambient. No heatsink is required for typical 8-bit MCU workloads.
