PIC16F1618-I/ML 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), working memory (RAM), and programmable I/O peripherals. The 8-bit MCU class uses an internal data bus 8 bits wide and is favoured for deterministic real-time control, simple toolchains, and very low active and sleep currents. Within the 8-bit category, the PIC16 family is one of the most widely deployed architectures, spanning general-purpose, motor-control, and low-power XLP variants. The PIC16F1618 sits in the XLP branch, optimised for battery-powered and energy-harvesting applications.
Key features include a 10-bit ADC with up to 12 channels, CCP/SCCP/PWM/24-bit SMT (Signal Measurement Timer) peripherals, Zero Cross Detect, a CLC (Configurable Logic Cell) block, multiple communication interfaces, and 18 I/O pins. The device operates from 2.3 V to 5.5 V, has an instruction cycle of 125 ns at 32 MHz, and supports both industrial (-40C to +85C) and extended (-40C to +125C) temperature ranges.
Architecturally, the PIC16F1618 uses a Harvard RISC core with a 14-bit instruction word, an internal oscillator, and Microchip's nanoWatt XLP technology that delivers sleep currents down to the low nA range. The high-integration peripherals - including 24-bit SMT for precision time measurement, CLC for glue-logic replacement, and PWM with complementary outputs - reduce external component count and BOM cost.
Typical applications include small motor control (BLDC, stepper, fan), LED lighting control, consumer electronics, battery-powered IoT sensor nodes, and general-purpose embedded control. The wide operating voltage range and low power make it well suited for both line-powered industrial and battery-powered portable products.
When designing with the PIC16F1618, ensure the exposed thermal pad (EP) is soldered to a sufficiently large copper pour for both thermal dissipation and mechanical reliability. Decouple VDD with a 100 nF ceramic capacitor placed as close as possible to the pin pair, and follow Microchip's recommended ICSP programming layout if in-circuit programming is required.

主な用途
PIC16F1618-I/ML の用途: 7 件s: Small Motor Control (BLDC / Stepper / Fan), LED Lighting Control and Dimming, Battery-Powered IoT Sensor Nodes, Consumer Appliance Control, Power Conversion and SMPS Auxiliary Control, Automotive Body and Interior Modules, Industrial Sensor Signal Conditioning.
Small Motor Control (BLDC / Stepper / Fan)
The PIC16F1618-I/ML fits small motor-control designs because it integrates a 32 MHz PIC16 core, complementary PWM outputs, and a 24-bit Signal Measurement Timer (SMT) that captures back-EMF period with sub-microsecond resolution - critical for sensorless BLDC commutation. With 7 KB Flash and 512 B SRAM, the MCU can host a sensorless FOC or trapezoidal commutation state machine plus UART diagnostics. The 2.3-5.5 V VDD range allows direct drive from a 1S Li-ion or 5 V regulated rail, and the CLC block replaces external glue logic that would otherwise latch fault signals. Pair with a 3-phase gate driver such as the Microchip TC654 or the TI DRV8313 for a complete 12 V/24 V fan or pump controller.
おすすめ
LED Lighting Control and Dimming
The PIC16F1618-I/ML is well matched to dimmable LED drivers thanks to its Zero Cross Detect (ZCD) peripheral, which synchronises TRIAC or MOSFET switching to the AC line without an external optocoupler. The 18 I/O pins drive multiple channels of constant-current LED strings, while the 10-bit ADC senses both supply voltage and LED current for closed-loop regulation. The 32 MHz CPU executes PWM dimming updates at > 10 kHz with no visible flicker, and XLP nanoWatt sleep modes keep standby power below 50 mW for Energy Star compliance. The 20-QFN 4x4 mm footprint fits inside GU10 bulbs and linear LED tubes where PCB area is severely constrained.
おすすめ
Battery-Powered IoT Sensor Nodes
The PIC16F1618-I/ML is a strong fit for battery-powered sensor nodes thanks to its nanoWatt XLP technology, which delivers sleep currents in the low-nA range and active currents around 1 mA at 1 MHz. The 10-bit ADC reads temperature, humidity, or gas-sensor outputs at intervals measured by the 24-bit SMT for precise wake-up timing. The wide 2.3-5.5 V VDD window accepts direct 3.3 V coin-cell or 1S Li-ion power, and the 20-QFN 4x4 mm package leaves room for a CR2032 holder and a small antenna. The CLC block implements edge-detection and pulse-counting without waking the CPU, extending battery life to several years on a single coin cell.
おすすめ
Consumer Appliance Control
The PIC16F1618-I/ML suits consumer appliances such as coffee makers, rice cookers, air purifiers, and small kitchen devices where its 18 I/O pins drive keypads, relays, seven-segment or LCD displays, and triac outputs. The Zero Cross Detect synchronises AC loads to the mains for quiet switching, and the 32 MHz core runs user-interface state machines plus temperature-control loops in a single chip. The 2.3-5.5 V range supports direct 3.3 V or 5 V operation, and the QFN-20 footprint fits inside slim product enclosures. The 7 KB Flash is sufficient for menu logic, safety interlocks, and basic PID control without external memory.
おすすめ
Power Conversion and SMPS Auxiliary Control
The PIC16F1618-I/ML can serve as the auxiliary/digital supervisor in a switched-mode power supply, using its 24-bit SMT for high-resolution frequency measurement of the main converter and its 10-bit ADC for output voltage sensing. The CLC and PWM peripherals implement digital current-mode control loops, while the PIC16 core executes telemetry and PMBus-style communication over I2C. The wide 2.3-5.5 V VDD window is compatible with both 3.3 V and 5 V bias rails commonly used in digital supervisors. The 20-QFN package integrates neatly on the secondary side of an isolated converter PCB.
おすすめ
Automotive Body and Interior Modules
The PIC16F1618-I/ML supports body and interior automotive applications such as LED interior lighting, HVAC flap control, and accessory modules where 18 I/O and PWM control are sufficient. The integrated Zero Cross Detect enables quiet AC-side switching, while the 32 MHz core runs LIN-style communication stacks and basic diagnostics. For under-hood or AEC-Q100-qualified designs, the PIC16F1618-E/ML extended-temperature variant is rated to +125 C and is pin-compatible. The QFN-20 4x4 mm footprint fits inside small inline connector housings common in automotive wiring harnesses.
おすすめ
Industrial Sensor Signal Conditioning
The PIC16F1618-I/ML is suitable for industrial 4-20 mA loop-powered sensor transmitters and bridge-sensor signal conditioners. The 10-bit ADC digitises bridge or RTD signals while the 24-bit SMT measures excitation pulse width for ratiometric compensation. The 2.3-5.5 V VDD range accepts a wide range of loop supply voltages, and the PIC16 XLP sleep modes keep total loop current draw below 3.5 mA, complying with NAMUR NE43 fault thresholds. The QFN-20 4x4 mm package fits inside a TO-5 or DIN-B head transmitter housing.

設計ノート
Estimated: for the 20-QFN (4x4 mm) package, the exposed thermal pad (pin 21) must be soldered to a ground-pour copper area of at least 10 mm x 10 mm on the top layer for adequate thermal dissipation. Place a 100 nF (0.1 uF) X7R ceramic decoupling capacitor within 3 mm of the VDD pin (pin 14) with a short, wide trace to pin 10 (VSS). For ICSP programming, expose the ICSPDAT (RA0), ICSPCLK (RA1) and MCLR (RA3) signals on test pads to allow in-circuit firmware updates.
The PIC16F1618-I/ML's RA3 pin doubles as the MCLR reset input. When using RA3 as a general-purpose I/O, the configuration bit MCLRE must be cleared to disable the reset function, or unexpected resets will occur. Also avoid leaving unused I/O pins floating - configure them as outputs driving low or as inputs with the internal weak pull-ups enabled, to minimise sleep current and prevent unintended peripheral triggers.
Estimated: although the PIC16F1618-I/ML dissipates < 100 mW in typical 32 MHz / 3.3 V applications, the small 20-QFN package relies on the exposed pad for cooling. Without a proper thermal pad connection, junction temperature can rise 30-40 C above ambient at full CPU load. Microchip's 'PIC16F161X Family Packaging and Thermal Considerations' application note recommends a minimum 1 oz copper pour with thermal vias to an internal ground plane.
Use the PIC16F1618-I/ML's nanoWatt XLP sleep modes (Sleep, Doze, Idle) for battery-powered designs. Sleep current with RTC running from the LFINTOSC is approximately 30 nA typical, allowing multi-year battery life on a CR2032 coin cell when wake-ups are infrequent. Always disable unused peripherals in the firmware before entering Sleep to minimise residual current draw from ADC, PWM, and CLC blocks.
