PIC16LF1779-E/PT - 8-bit MCU, 28KB Flash, 44-TQFP | Microchip
MPN: PIC16LF1779-E/PT ✓ פעילPIC16LF1779-E/PT סקירה
An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (ADC, timers, PWMs, communication ports) into one package. Within the broader semiconductor hierarchy, MCUs sit under microcontrollers -> embedded processors -> digital ICs. The PIC16F177x family in particular targets applications needing advanced analog and digital peripherals for lighting, power conversion, motor control, and sensor signal conditioning.
Key features of the PIC16LF1779 include the integrated 10-bit ADC, multiple 8-bit and 16-bit timers, Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) and SPI/I2C peripherals, up to 36 digital I/O pins, and support for Microchip's eXtreme Low-Power (XLP) technology. The 44-TQFP package exposes most of the I/O and analog channels, enabling concurrent ADC sampling and PWM output on the same die.
Typical applications include LED lighting drivers, digital power supply controllers, motor-control front-ends, sensor hubs, and battery-powered industrial IoT nodes. The 1.8V minimum supply makes the part suitable for single-cell Li-ion (3V nominal) rails and 3.3V regulated industrial buses.
When designing with the PIC16LF1779, ensure the supply decoupling network follows Microchip application note TB3131 recommendations. Unused I/O pins must be configured as outputs and tied low to minimize current draw. Programming is performed through the ICSP interface, requiring the standard ICSPDAT/ICSPCLK lines preserved on the PCB.

יישומים טיפוסיים
PIC16LF1779-E/PT מתאים עבור 6 יישוםs: LED Lighting Drivers, Industrial Sensor Hubs, Digital Power Supply Controllers, Motor Control Front Ends, Battery-Powered IoT Sensor Nodes, Automotive Body Electronics (Industrial-Grade).
LED Lighting Drivers
The PIC16LF1779-E/PT is well-suited to LED lighting applications, providing 28 KB of Flash, multiple PWM outputs, and a 10-bit ADC for closed-loop current sensing. The 32 MHz core executes Microchip's LED control firmware and digital dimming curves in real time. Compared with discrete 555-based drivers, the integrated MCU enables I2C/UART dimming control and per-channel calibration within a single BOM. Use PIC16LF1779-E/PT when you need four or more PWM channels with synchronized phase shifting.
מומלץ
Industrial Sensor Hubs
In industrial sensor hubs the PIC16LF1779-E/PT acts as the aggregator that reads multiple analog sensors via its 10-bit ADC and forwards telemetry over EUSART, SPI, or I2C. The 44-TQFP footprint exposes 36 I/O pins enabling parallel sensor capture without external mux. The XLP nanoWatt sleep mode (<100 nA typical) preserves battery life on remote wireless nodes. Choose PIC16LF1779-E/PT for IO-rich, 3.3V-powered sensor hubs in industrial environments.
מומלץ
Digital Power Supply Controllers
The PIC16LF1779-E/PT serves as a digital supervisor in switch-mode power supplies (SMPS) by handling soft-start, fault detection, and adaptive dead-time adjustment via firmware. The 32 MHz core runs control loops at the rates digital power demands, while the integrated ADC samples current/voltage feedback. The 1.8-3.6V range aligns with auxiliary housekeeping rails of a 3.3V SMPS. Use this part for SMBus telemetry or PMBus-style PMIC controllers below 50W.
מומלץ
Motor Control Front Ends
Brushless-DC (BLDC) and brushed motor pre-drivers benefit from the PIC16LF1779-E/PT's PWM generators with dead-band control, quadrature encoder input, and 10-bit ADC for current sensing. The 28KB Flash holds full BLDC six-step or field-oriented control (FOC) software; the 32 MHz CPU computes commutation in tens of microseconds. For sub-200W motor-control boards this single chip replaces several discrete components.
מומלץ
Battery-Powered IoT Sensor Nodes
With XLP technology, the PIC16LF1779-E/PT suits battery-powered IoT sensor nodes. It draws sub-100 nA in sleep, wakes from interrupt on a sensor event, samples the ADC, transmits via UART, and returns to sleep - all on a single CR2032 cell for multi-year deployments. The 1.8V minimum VDD allows direct use at end-of-discharge battery voltage without a boost converter.
מומלץ
Automotive Body Electronics (Industrial-Grade)
The PIC16LF1779-E/PT (extended-grade, -40C to +125C) is used in automotive body electronics applications that do not require full AEC-Q100 qualification, such as interior accessories, lighting modulators, or convenience modules. The 10-bit ADC and PWM peripherals handle body control tasks like window lifters, seat adjusters, or HVAC mode selectors in industrial-grade environments.

הערות תכנון
Decouple VDD with a 100 nF X7R ceramic placed within 5 mm of the device pin, plus a bulk 1-10 uF tantalum or ceramic across VDD and VSS. The 44-TQFP has two VSS pins (9 and 17) and one VDD pin (18); route each VSS to a low-impedance ground plane via its own via, and the single VDD pin should reach the bulk cap before reaching external load circuits.
Configure ALL unused I/O pins as outputs driving low to keep them in their lowest power state. Floating input pins can toggle into the digital input buffer of the PIC16LF1779-E/PT and waste nanoWatt sleep-mode current. The MCLR pin must be pulled high to VDD with a 10 kOhm resistor (NOT connected directly) when no external reset is required.
Route ICSPDAT/ICSPCLK (RB7/RB6) pins straight out and keep them short - 50 mm max - for reliable in-circuit serial programming. Per Microchip TB3131, the ICSP connector should be on the bottom layer or board edge to minimize trace stubs and avoid coupling noise onto the programming signals.
Estimated: the PIC16LF1779-E/PT TQFP-44 thermal resistance (Theta_JA) is approximately 39.5 C/W on a 4-layer JEDEC test board. At maximum active-mode current of approximately 4 mA at 32 MHz and 3.3V, power dissipation stays below 14 mW, so the junction temperature rise above ambient is well under 1 C - no heatsink required. Watch for current spikes at I/O switching rather than steady-state CPU draw for thermal margin estimation.
