PIC16LF1776T-I/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), peripherals and I/O on one IC. The PIC16F family uses a RISC-based 8-bit core optimized for deterministic, low-latency control loops, while the "LF" prefix indicates the wide-voltage, low-power variant suitable for battery and energy-harvesting systems. PIC MCUs sit in the broader semiconductor hierarchy: microcontroller -> embedded processor -> integrated circuit, and are widely deployed where predictable real-time behavior matters more than raw compute throughput.
Key features of the PIC16LF1776 include 14KB self-programmable Flash (8K × 14 words), 1KB RAM, four 10-bit DACs, two op-amps, two high-speed comparators, programmable ramp generator (PRG), zero-cross detect (ZCD), complementary waveform generators for 10/16-bit PWMs, 100 mA capable I/Os, peripheral pin select (PPS), and serial interfaces including SPI, I²C and EUSART. The wide 1.8V-3.6V Vdd range plus XLP™ nanoWatt technology extends battery life in always-on designs.
The architecture pairs a Harvard RISC core with an on-chip 32MHz oscillator and Microchip's Core Independent Peripherals (CIPs) — peripherals that run without CPU intervention. This combination enables accurate, deterministic closed-loop control for LED drivers, digital power supplies, and BLDC motor commutation without burdening the main core.
Typical applications include high-performance LED lighting with dimming and color-mixing, switched-mode power supplies with digital compensation, battery-charging and battery-management systems, sensor signal conditioning, industrial control loops, and small motor-control boards. The on-chip 10-bit DACs and op-amps simplify analog front-ends, while the 100 mA I/Os can directly drive LED strings or small relays.
When designing with this part, leverage PPS to remap peripherals to almost any I/O pin, easing PCB layout, and use the complementary PWM outputs together with the programmable ramp generator for high-resolution, dead-band-controlled power-stage timing. For power budgeting, the XLP™ sleep current in the nanoamp range is critical for long-life battery or energy-harvesting products.

主な用途
PIC16LF1776T-I/SO の用途: 6 件s: High-Performance LED Lighting Drivers, Digital Switched-Mode Power Supplies (SMPS), Battery Charging and Battery Management Systems, BLDC and Brushed-DC Motor Control, Sensor Signal Conditioning and Industrial Sensing, Consumer Appliance and White Goods Control.
High-Performance LED Lighting Drivers
The PIC16LF1776T-I/SO is ideal for high-performance LED lighting drivers thanks to its 10/16-bit complementary PWMs, programmable ramp generator (PRG), zero-cross detect (ZCD), four 10-bit DACs and 100 mA capable I/Os in a single 28-SOIC package. Designers can implement smooth analog-style dimming, color-mixing across multiple LED strings and flicker-free high-frequency PWM using the on-chip 16-bit PWM at 32 MHz, achieving >1 MHz PWM resolution. The 4 DACs let multiple LED strings be driven with independent analog currents while the complementary outputs deliver on-board half-bridge timing for boost or buck topologies. XLP™ nanowatt sleep current extends battery life in mains-off standby. Unlike an external LED-driver IC, the PIC16LF1776T-I/SO adds an 8-bit CPU to run custom color algorithms, networked lighting protocols, or fault diagnostics without a second MCU.
おすすめ
Digital Switched-Mode Power Supplies (SMPS)
The PIC16LF1776T-I/SO excels in digital SMPS and PFC applications because its high-speed comparators feed directly into the programmable ramp generator for peak-current-mode and average-current-mode control without external glue logic. Its 10/16-bit complementary PWMs with programmable dead-band directly control synchronous half-bridge FET timing, while the four 10-bit DACs set reference voltages for voltage-mode and current-mode loops. The 32 MHz core executes compensation math with deterministic interrupt latency, supporting switching frequencies above 250 kHz. The 1.8-3.6 V wide-Vdd "LF" variant runs directly from auxiliary bias rails of offline converters, simplifying start-up sequencing. Compared with a pure analog controller, the PIC16LF1776T-I/SO enables adaptive dead-time, soft-start profiling, and telemetry via EUSART or I²C without firmware overhead.
おすすめ
Battery Charging and Battery Management Systems
The PIC16LF1776T-I/SO is well matched to single-cell and multi-cell battery charging and battery management designs because its XLP™ nanowatt technology keeps quiescent current in the nanoamp class during sleep, preserving charge in always-on battery packs. Two on-chip op-amps sense charge/discharge current with low-offset, two high-speed comparators detect end-of-charge and over-current events, and four 10-bit DACs set programmable charge-voltage and charge-current references. The wide 1.8-3.6 V Vdd runs directly from a single Li-ion/LiFePO4 cell. Complementary 16-bit PWMs drive synchronous buck/boost chargers with precise dead-band, eliminating shoot-through. PPS allows flexible pin routing for safety-critical signals. Compared with discrete battery management ICs, the PIC16LF1776T-I/SO adds a full 8-bit CPU for state-of-charge algorithms and SMBus/EUSART telemetry.
おすすめ
BLDC and Brushed-DC Motor Control
The PIC16LF1776T-I/SO is a strong fit for small BLDC and brushed-DC motor control boards because its 10/16-bit complementary PWMs with programmable dead-band directly drive half-bridges or full H-bridges for 1-2 phase stepper, brushed-DC and BLDC motors. The high-speed comparators handle back-EMF zero-cross sensing for sensorless BLDC commutation, and the four 10-bit DACs set torque/speed reference profiles. PRG provides hardware slope compensation for current loops at low PWM duty cycles, and ZCD simplifies AC-line-synchronized timing. With 32 MHz core speed and 8 MIPS throughput, real-time FOC and trapezoidal commutation both fit inside the 14 KB Flash. PPS lets the designer reassign PWM phases for optimal PCB routing. Compared with a dedicated motor-control IC, this part adds full programmability for custom motion profiles.
おすすめ
Sensor Signal Conditioning and Industrial Sensing
The PIC16LF1776T-I/SO is ideal for industrial sensor signal conditioning because its two on-chip op-amps, two high-speed comparators, four 10-bit DACs and 10/16-bit ADC sampling combine into a complete analog front-end on a single die. Designers can amplify a thermocouple or strain-gauge signal, drive a Wheatstone-bridge excitation reference from a DAC, and digitize the result at 32 MIPS — without external analog ICs. PPS eases routing of mixed analog and digital signals, while 100 mA I/Os can directly switch relays or 4-20 mA loops. The 1.8-3.6 V wide Vdd runs from 24 V industrial loops through a small LDO. Compared with a standalone op-amp + ADC chain, the PIC16LF1776T-I/SO integrates calibration, linearization, and HART/EUSART comms in one chip.
おすすめ
Consumer Appliance and White Goods Control
The PIC16LF1776T-I/SO suits washing machines, refrigerators, induction cooktops, coffee machines and small kitchen appliances because it integrates brushed/BLDC motor control, LED display driving and user-interface handling in one 28-SOIC IC. Its complementary PWMs handle motor or induction-heating inverter switching, the four 10-bit DACs set analog references for temperature and power, and the high-speed comparators perform zero-cross detection on the AC mains for synchronous TRIAC driving. The on-chip EUSART and I²C connect to displays, keypads, and wireless modules. Wide 1.8-3.6 V Vdd tolerates noisy rectified mains rails after a small regulator. Compared with multi-chip solutions, the PIC16LF1776T-I/SO lowers BOM cost and PCB area while keeping full firmware flexibility.

設計ノート
Estimated: at Vdd=3.3 V and 32 MHz active, typical IDD for the PIC16LF1776 core is around 4 mA (≈0.13 mA/MHz). Place a 100 nF decoupling capacitor as close as possible to the Vdd pin (pin 16) and a 10 µF bulk cap on the same rail. Add a 1 µF cap on the Vcap pin (pin 27) to stabilize the internal core voltage regulator — omitting this capacitor is a common cause of erratic resets.
Use Peripheral Pin Select (PPS) to remap digital peripherals (CCP, SPI, I²C, EUSART) to almost any digital I/O. This greatly simplifies PCB routing — you can route the SPI bus to one side of the SOIC and remap the UART to another side without swapping the MCU. Refer to the PPS input/output selection tables in the device datasheet, and remember PPS must be unlocked via the PPSLOCK register sequence on every reset.
The two op-amps, four DACs and high-speed comparators share analog pins with digital I/O. Configuring a pin as a digital output while the analog peripheral is enabled can create contention and corrupt the analog reading — always configure the analog function first, then disable the digital input on that pin (ANSELx register). Also, the PRG requires a slope-compensation input pin; miswiring this leads to subharmonic oscillation in peak-current-mode supplies.
The 28-SOIC package has a moderate θJA of roughly 80-90 °C/W on a standard 2-layer JEDEC test board. Estimated: at maximum Vdd (3.6 V), 32 MHz active and full peripheral activity, power dissipation stays well below 100 mW, so no heatsink is required. However, in a sealed industrial enclosure at 85 °C ambient, derate current on the 100 mA I/O banks to avoid exceeding the silicon junction limit.
