PIC16LF18425T-I/JQ - 8-bit 32MHz MCU 14KB Flash 16-UQFN | Microchip

The Microchip PIC16LF185185T-I/JQ is an 8-bit PIC16F microcontroller from Microchip's PIC16(L)F184xx product family, featuring a 32MHz CPU, 14KB of Flash program memory, 1024 bytes of SRAM, and 256 bytes of EEPROM, all housed in a 16-lead UQFN (4x4) package. Key specifications include 1.8V to 3.6V operating voltage, two PWMs, a comparator, a 5-bit DAC, a 12-bit ADC with computation (ADCC), a configurable logic cell (CLC), a complementary waveform generator (CWG), EUSART, SPI, and I2C communication peripherals. The 'LF' prefix designates the low-voltage variant, and 'XLP' (eXtreme Low Power) technology enables sub-microamp sleep currents, making this part ideal for battery-powered applications. The 16-UQFN (4x4 mm) package option targets space-constrained designs where board area is at a premium. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and configurable peripherals on a single silicon die. PIC16F MCUs use a Harvard-architecture RISC core optimized for deterministic real-time control, and the 184xx family extends this with Core Independent Peripherals (CIPs) that operate autonomously without CPU intervention. The PIC16LF18425T-I/JQ belongs to the broader hierarchy: microcontroller -> 8-bit MCU -> PIC16F family -> XLP low-power subfamily, and is manufactured using CMOS process technology. Key differentiating features of the PIC16LF18425T-I/JQ include its 12-bit ADCC with automated averaging, oversampling, and threshold comparison, reducing firmware complexity for sensor monitoring. The CWG module generates complementary dead-band-controlled waveforms typically required for half-bridge power stages. The CLC allows combinatorial logic between peripherals to be wired in hardware, enabling custom glue logic without code overhead. Combined with 32MHz operation and 14KB of code space, these CIPs deliver high analog integration density for sensor and motor-control applications in a tiny 16-UQFN footprint. Architecturally, the PIC16LF18425T-I/JQ is built around the enhanced mid-range PIC16 core with a 14-bit instruction word, allowing each Flash location to store a single instruction and giving the part its 8K x 14 Flash organization. The 32MHz internal oscillator (with PLL) yields a 125ns instruction cycle, supporting precise timing in motor-control loops. XLP technology integrates nanoWatt XLP sleep modes, allowing the device to wake on peripheral triggers while drawing under 1 uA, ideal for energy-harvesting or coin-cell applications. Multiple I/O (12 of 16 pins) and high-current sink/source capability simplify driving LEDs, keypads, and power transistors directly. Typical applications include IoT sensor nodes, low-power wireless edge devices, battery-powered handheld instruments, LED lighting control, and small BLDC motor control. The combination of XLP sleep modes and 12-bit ADCC makes this MCU especially attractive for periodic-sampling sensor products where multi-year battery life is a primary design goal. When designing with this device, ensure your Vdd decoupling follows the manufacturer recommendations (typically 0.1 uF and 10 uF in parallel) and that unused I/O are configured as outputs low or inputs with internal pull-ups to minimize sleep current.

PIC16LF18425T-I/SL

PIC16LF18425T-I/SL - 14KB Flash XLP MCU | Microchip | SOIC-14

The Microchip Technology PIC16LF18425T-I/SL is an 8-bit PIC16 microcontroller from the PIC16F18425 family, featuring 14KB of Flash program memory (8K x 14 words), 1KB of RAM, and a 32MHz internal oscillator, packaged in a 14-pin SOIC (SL) package. The 'LF' prefix indicates an extended eXtreme Low-Power (XLP) variant operating from 1.8V to 3.6V, while the 'T' suffix denotes Tape & Reel packaging and 'I' indicates the industrial -40C to +85C temperature range. An 8-bit microcontroller (MCU) is a compact computing core that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals onto a single chip. PIC MCUs use a Harvard RISC architecture, where program and data buses are separated, allowing simultaneous instruction fetch and operand access in a single clock cycle. Within the broader semiconductor taxonomy, an MCU is a sub-class of microcontroller IC, itself a member of the integrated circuit family, designed for embedded control tasks rather than general computing. Key features of this device include two PWM modules, comparators, a Digital-to-Analog Converter (DAC), a 12-bit Analog-to-Digital Converter with Computation (ADCC), a Complementary Waveform Generator (CWG), an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), and SPI/I2C interfaces. These Core Independent Peripherals (CIPs) handle tasks autonomously from the CPU, freeing it for application logic and reducing firmware complexity. The 12-bit ADCC provides automated averaging, threshold detection, and hardware accumulation, enabling energy-efficient sensor acquisition. The PIC16LF18425T-I/SL also benefits from Microchip's eXtreme Low-Power (XLP) technology, supporting sleep currents down to the nanoampere range and active-mode efficiencies suitable for battery-powered sensor nodes. The 32MHz maximum CPU speed delivers up to 8 MIPS of throughput. The 14-pin SOIC package provides a robust, hand-solderable footprint with a 1.27mm pitch and standard 3.90mm body width, suitable for prototyping as well as volume manufacturing. Typical applications include IoT sensor nodes, battery-powered remote controls, low-power wireless sensor interfaces, LED lighting controls with dimming feedback, small motor control loops via the CWG, and consumer appliance user-interface panels. The combination of compact 14-pin packaging, low operating voltage, and rich analog peripherals makes it well-suited for space-constrained, energy-conscious designs. When designing with this part, ensure the supply voltage stays within the 1.8V to 3.6V LF range, since the non-LF PIC16F18425 variant is rated for 2.3V to 5.5V operation. Decouple VDD with a 100nF ceramic capacitor placed within 3mm of the pin, and reserve the ICSP pins (ICSPCLK/ICSPDAT) for in-circuit programming during development.

It integrates 14KB of Flash program memory, 1KB of SRAM, 256 bytes of EEPROM, and a rich set of Core Independent Peripherals (CIPs) including 12-bit ADCC, 5-bit DAC, two comparators, two PWM modules, a Complementary Waveform Generator (CWG), and configurable logic cells. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. It is one of the most widely deployed computing architectures in the world because of its deterministic instruction cycle, low cost, low power consumption, and ease of programming. Within the broader semiconductor hierarchy, an 8-bit MCU is a sub-category of microcontroller -> embedded processor -> integrated circuit. The PIC16 core belongs to the Reduced Instruction Set Computer (RISC) family and executes most instructions in one instruction cycle, giving it deterministic throughput that is highly valued in real-time control loops. Key features include operation from 1.8V to 3.6V, an operating temperature range of -40C to +85C (industrial grade, indicated by the "I" in the part number), 11 timers, a 12-bit Analog-to-Digital Converter with Computation (ADCC) supporting automatic averaging, filtering and threshold comparison, and communication peripherals including EUSART, SPI, and I2C. The XLP nanoWatt technology enables sleep currents in the nanoamp range, which is critical for battery-powered applications such as IoT sensors and wearables. Architecturally, the device combines a Harvard-bus PIC16 CPU core with on-chip debug support, a wide array of Core Independent Peripherals (CIPs) that offload tasks from the CPU, and the Peripheral Pin Select (PPS) feature that allows digital peripheral I/O to be remapped to a wide choice of pins. This combination gives designers a flexible platform for mixed-signal embedded designs. Typical applications include low-power IoT sensor nodes, battery-powered wearables, consumer appliances, LED lighting controllers, automotive body and sensor nodes, and small industrial control boards. The 14-pin TSSOP footprint with PPS makes it suitable for compact designs where pin flexibility is essential. When designing with this device, ensure the power supply rail stays within the 1.8V to 3.6V window and provide proper decoupling close to the VDD/VSS pins. Note that the "LF" prefix indicates the low-voltage (1.8V-3.6V) variant - if a 5V supply rail is required, select the PIC16F18425 (non-LF) version instead, which shares the same 14-pin TSSOP pinout. The trailing "T" denotes tape-and-reel packaging for high-volume assembly. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, so engineers can quickly evaluate the PIC16LF18425T-I/ST against drop-in substitutes for sourcing risk mitigation.

PIC16LF18426-E/JQ - 8-Bit XLP MCU 32MHz 28KB Flash | Microchip

The Microchip Technology PIC16LF18426-E/JQ is an 8-bit PIC microcontroller built on the enhanced mid-range core, delivering 32 MHz CPU performance from 28 KB (16K x 14) of Flash program memory, 2 KB of SRAM, and 256 bytes of EEPROM, all housed in a compact 16-pin UQFN-EP 4x4 mm package. It integrates Core Independent Peripherals (CIPs) such as a 12-bit ADC with Computation (ADCC), a 5-bit/8-bit DAC, two comparators, two 10-bit PWMs, Complementary Waveform Generator (CWG), Zero-Cross Detect (ZCD), and EUSART/SPI/I2C interfaces, providing high functional density for sensor and IoT nodes. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path, optimized for deterministic real-time control, low power, and cost-sensitive embedded designs. Within the broader taxonomy, PIC16LF18426 sits under PIC microcontroller -> 8-bit MCU -> microcontroller unit -> integrated circuit -> semiconductor. The "LF" prefix denotes the eXtreme Low-Power (XLP) process variant, supporting operation from 1.8 V to 3.6 V with nanoWatt sleep currents in the order of tens of nanoamps, while the non-LF "F" variant extends to 5.5 V. Key features of the PIC16LF18426-E/JQ include active current consumption below 1 mA at 32 MHz with 3.3 V VDD, deep sleep currents below 100 nA with peripheral retention via the Windowed Watchdog Timer (WWDT), and 4 KB of self-programmable Flash. The device offers up to 17 I/O pins, internal 32 kHz and 32 MHz oscillators, and a temperature-indicator module that simplifies thermal monitoring. AEC-Q100 qualification is available on selected part numbers for automotive-grade designs. The PIC16LF18426 family uses a 14-bit instruction word RISC architecture with a single-cycle hardware multiplier, allowing many CIP operations to run independently of the CPU. This produces deterministic latency for sensor front-ends while keeping CPU wake time short - a critical balance for battery-powered edge devices. Typical applications include battery-powered IoT sensor nodes, low-power remote controls, wearable health and fitness devices, white-goods and appliance controllers, automotive body and lighting ECUs (AEC-Q100 parts), and industrial sensor transmitters. The combination of ADCC, ZCD, CWG, and PWMs enables single-chip control loops previously requiring dedicated analog ASICs. Design consideration: when migrating from a 5V PIC16F18426 to the 3.3V PIC16LF18426, verify that all peripherals operate at the lower rail - the LF device is not 5V tolerant on I/O. A simple BOM change to a 3.3V LDO is usually sufficient. Always place a 100 nF decoupling capacitor within 3 mm of VDD and a 10 uF bulk capacitor near the package.

Typical applications include IoT sensor nodes, low-power remote controls, battery-powered instrumentation, LED lighting controllers, simple motor-control loops, and industrial sensor signal conditioning. Engineers select this device when they need more analog integration than smaller-pin PICs offer but still want through-hole prototyping convenience. A key design consideration is the 'LF' suffix indicating the low-voltage / F-version silicon: this device operates down to 1.8V and is the preferred choice for coin-cell or Li-Ion battery systems; for designs that must run up to 5.5V, the PIC16F18426-E/P (non-LF) is the recommended counterpart. Always add a 0.1 µF decoupling capacitor close to VDD and follow Microchip's startup configuration guidelines to achieve the rated nanoampere sleep currents.

PIC16LF18426-E/SL - 8-bit MCU, 28KB Flash, 32MHz, XLP | Microchip

The Microchip Technology PIC16LF18426-E/SL is an 8-bit RISC microcontroller from the PIC16 (L)F184xx family, featuring 28KB (16K x 14 words) of Flash program memory and 2KB of SRAM data memory, operating at up to 32MHz internal core clock. The device is housed in a 14-pin SOIC (SL) package with an industrial -40C to +125C extended operating temperature range, designated by the "E" temperature suffix and "L" (low-power) voltage variant. An 8-bit PIC microcontroller is a single-chip computer built around a RISC core with separate program and data buses (Harvard architecture), which executes one instruction per clock cycle for predictable real-time performance. The PIC16F184xx family extends this baseline with Core Independent Peripherals (CIPs) such as CWG, NCO, and configurable logic cells, plus eXtreme Low-Power (XLP) modes for battery-sensitive designs. The "LF" prefix denotes a wide 1.8V to 3.6V supply range, differentiating it from the "F" variants (2.3V to 5.5V) within the same die family. Key features include a 12-bit ADC with Computation (ADCC) supporting up to 11 channels, a 5-bit DAC, two PWMs with complementary outputs, a Comparator, Zero-Cross Detect (ZCD), temperature sensor, Fixed Voltage Reference (FVR), EUSART, SPI, and I2C communication peripherals. The device integrates 256 bytes of EEPROM and includes peripheral pin select (PPS) for flexible signal routing. These CIPs allow hardware-level state machine control without CPU intervention, reducing active-mode current draw. The PIC16LF18426 uses a modified Harvard RISC core with 14-bit instruction words and an internal 32MHz oscillator block with four selectable PLL modes. XLP technology provides typical 50 nA sleep current in Retention mode and sub-uA RTC current from the 32kHz LFINTOSC, enabling multi-year coin-cell battery operation. The integrated 12-bit ADCC performs averaging, oversampling, and threshold comparisons autonomously. Typical applications include IoT sensor nodes, wearable health devices, battery-powered remote controls, low-power wireless HMI controllers, energy-harvesting systems, and industrial sensor signal conditioning with on-chip analog. The wide 1.8V to 3.6V VDD range supports single-cell alkaline, NiMH, or Li-MnO2 battery chemistries directly without external regulation. When designing with this MCU, configure PPS to map peripherals to the limited 14-pin SOIC I/O set and verify the 2KB SRAM budget for buffered communication stacks. Choose the "LF" variant only when sub-3.6V supply is mandatory; otherwise the "F" variant (PIC16F18426) is more readily available.

It is part of Microchip's eXtreme Low Power (XLP) product family, suited for battery-powered and energy-harvesting applications. What is a PIC16 microcontroller? A PIC16 microcontroller is a class of 8-bit RISC microcontrollers from Microchip Technology built on a Harvard architecture with separate program and data buses. The PIC16LF18426 belongs to the PIC16 family > mid-range 8-bit MCU > microcontroller > embedded processor > semiconductor. It is the workhorse tier of Microchip's 8-bit portfolio, positioned above baseline PIC10/PIC12 and below 16-bit PIC24/dsPIC33 devices. The 'LF' prefix denotes an extended voltage window (typically 1.8 V to 3.6 V) for low-power operation, while the 'F' family in the part number indicates Flash program memory. Key features of the PIC16LF18426-E/ST include: a 12-bit ADC with Computation (ADCC) capable of up to 140 ksps, a 5-bit DAC, two PWMs with complementary outputs, a Comparator, Zero-Cross Detect (ZCD), Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and a temperature sensor. Communication peripherals cover EUSART, SPI, and I2C. Core Independent Peripherals (CIPs) handle tasks in hardware without CPU intervention, reducing wake events and lowering system power consumption. Technically, the device supports multiple power-saving modes including Sleep, Idle, and Doze, with a typical Sleep current in the nanoampere range thanks to XLP technology. The 32 MHz internal oscillator eliminates the need for an external crystal in many designs, while the 14-bit instruction word and 8-level hardware stack simplify firmware development in MPLAB X IDE with XC8 compilers. Typical applications include IoT sensor nodes, low-power wireless transmitters, consumer appliances, battery management front-ends, smart home controls, LED lighting controllers, and small motor control loops. The TSSOP-14 footprint suits compact handheld designs where board real estate is at a premium and a full 20-pin variant would be excessive. When designing with the PIC16LF18426-E/ST, pay attention to the I/O count - the 14-pin package exposes fewer GPIO than the 20-pin variants in the same family. Engineers migrating from PIC16LF18425 or PIC16LF18325 silicon should verify pin mapping because peripheral remapping differs across pin counts in this family.

It operates from a wide 1.8V to 3.6V supply, runs at 32MHz internal oscillator, and integrates eXtreme Low-Power (XLP) technology for battery-friendly designs. The part carries the -I (industrial) temperature grade of -40C to +85C and is supplied on tape and reel. An 8-bit PIC microcontroller is a small, low-power programmable processor built around a Harvard-architecture RISC core. Within the broader taxonomy, PIC MCUs belong to microcontrollers (MCU) -> embedded processors -> semiconductors. They are favored for deterministic behavior, low quiescent current, and integrated analog/digital peripherals that reduce or eliminate external components, making them ideal for sensor nodes, consumer appliances, and ultra-low-power IoT endpoints where ARM Cortex-M0 parts would be over-spec and over-budget. Key features include 28KB (16K x 14) self-programmable Flash program memory, 2KB SRAM data memory, a 12-bit ADC with Computation (ADCC) for oversampling and averaging, a 5-bit DAC, two PWM modules, a comparator, a Complementary Waveform Generator (CWG), and serial interfaces including EUSART, SPI, and I2C. The device also provides up to 17 I/O pins and configurable logic cells, allowing designers to replace discrete glue logic with on-chip functions. The 12-bit ADCC delivers higher effective resolution than typical 10-bit MCU ADCs, while XLP sleep currents below 50 nA enable multi-year coin-cell lifetimes. Architecturally, the PIC16LF18426 uses a 14-bit instruction word with a 16-level hardware stack and an 8-bit data path. The ADCC integrates accumulation, averaging, and threshold comparison in hardware, offloading these tasks from the CPU and reducing firmware complexity. The CWG can synthesize complementary PWM outputs with programmable dead-band, useful for half-bridge driver control without dedicated timer resources. Typical applications include battery-powered sensor nodes, low-power IoT endpoints, white goods and small appliance controls, LED driving fixtures and lighting controllers, and remote controls. The wide operating voltage and ultra-low sleep current make it well suited to products that spend most of their time in sleep and only wake briefly to acquire and transmit data. When designing with this device, plan GPIO usage carefully because the 16-pin UQFN package exposes only a subset of the die's peripheral pins. Use MPLAB X IDE with the XC8 compiler and MPLAB Code Configurator (MCC) for peripheral setup. Place a 0.1uF decoupling capacitor close to VDD and tie the exposed pad to ground for thermal and electrical performance.

It belongs to the PIC16LF184xx family featuring eXtreme Low Power (XLP) technology and integrates 2 PWMs, a comparator, a 5-bit DAC, a 12-bit ADCC, a CWG (Complementary Waveform Generator), an EUSART, and SPI/I2C interfaces on a single die. The LF prefix indicates the wide 1.8V-3.6V operating range required for battery-powered designs. An 8-bit microcontroller (MCU) is a programmable processor built around an 8-bit data path, optimized for deterministic real-time control with low power consumption. Within the broader semiconductor hierarchy, an MCU is a microprocessor family -> microcontroller -> 8-bit MCU -> PIC16 family -> PIC16LF184xx sub-family. The PIC16 core uses a RISC-style Harvard architecture with 14-bit instruction words, giving 16 KB words of code space addressable from 28 KB Flash; the LF variant targets low-voltage, battery-backed applications. Key features include XLP sleep currents measured in the tens of nanoamperes, peripheral pin select (PPS) for flexible signal routing, an idle/doze/current-shielding scheme for power budgeting, and Core Independent Peripherals (CIPs) that execute timing-critical tasks without CPU intervention. The 12-bit ADCC and 5-bit DAC support sensor conditioning and bias generation, while the CWG drives synchronous MOSFET half-bridges for LED, motor, or PFC control. The integrated EUSART and SPI/I2C cover most sensor-bus and host-communication requirements. Typical applications include battery-powered IoT sensor nodes, low-power wireless remote controls, wearable health patches, energy-harvesting switches, e-metering peripherals, and industrial sensor conditioning front-ends. In each case the LF voltage range, the nanoampere sleep current, and the 12-bit ADC with internal reference remove the need for a separate analog front-end IC. When designing with this device, budget active and sleep currents separately: peak active current at 32 MHz from a 3.3 V rail is approximately 4-5 mA, while sleep current with the RTCC and ADC active stays below 1 microampere.

PIC16LF18444-E/P

PIC16LF18444-E/P - 8-Bit XLP MCU, 32MHz, 7KB Flash, 20-PDIP | Microchip

The Microchip Technology PIC16LF18444-E/P is an 8-bit RISC microcontroller from the PIC® XLP™ 16F family, featuring a 32MHz PIC16 CPU core with 7KB (4K x 14 words) of Flash program memory, housed in a 20-pin PDIP (0.300", 7.62mm) through-hole package. The "LF" prefix designates the wide-voltage, low-power variant supporting operation from 1.8V to 3.6V, making it ideal for battery-powered designs where eXtreme Low-Power (XLP) technology extends run-time. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, optimized for deterministic real-time control. The PIC16LF18444 sits within the broader taxonomy of microcontrollers -> embedded controllers -> microprocessors -> semiconductors. Its 8-bit architecture offers simpler instruction set, smaller code footprint, lower cost per MIPS, and predictable interrupt latency compared to 16-bit or 32-bit MCUs, making it well-suited for cost-sensitive, low-power sensor, motor, and IoT edge-node applications rather than graphics-rich or high-throughput DSP tasks. Key features include 7KB Flash program memory, 512 bytes of SRAM, 256 bytes of EEPROM, 12-bit ADC with Computation (ADC2), on-chip DAC, comparators, 2 PWMs, a Complementary Waveform Generator (CWG), and serial communication via EUSART, SPI, and I²C. Core Independent Peripherals (CIPs) handle timing, waveform synthesis, and signal conditioning without CPU intervention, freeing the CPU for application logic. The device uses a Harvard architecture with separate program and data buses, enabling single-cycle instruction execution except for branches. The 12-bit ADC2 with averaging, oversampling, and threshold comparison reduces firmware burden for sensor acquisition. Hardware CIPs including the CWG and configurable logic cells (CLC) implement state machines in silicon, often eliminating the CPU from tight control loops. Typical applications include low-power IoT sensor nodes, battery-powered remote controls, white-goods and home appliance control boards, automotive interior accessories (with appropriate grade), industrial sensor interfaces, and small motor control. The 20-PDIP package suits through-hole prototyping, hobby projects, and educational platforms where hand-soldering and breadboard compatibility are valued. When designing, ensure VDD decoupling follows Microchip's recommended 100nF + bulk capacitor pattern near the IC, reserve the MCLR pin reset circuit, and configure unused pins as outputs to minimize current. For lowest sleep current, disable unused peripherals via PMD registers.

PIC16LF18444-E/SS

PIC16LF18444-E/SS - 8-bit MCU, 7KB Flash, 32MHz, SSOP-20 | Microchip

The Microchip Technology PIC16LF18444-E/SS is an 8-bit RISC PIC microcontroller built on the enhanced mid-range PIC16 CPU core, featuring 7KB of Flash program memory, 512 bytes of SRAM and 256 bytes of data EEPROM, and packaged in a 20-pin SSOP (5.30 mm body width). It operates at clock speeds up to 32 MHz and supports a wide supply range of 1.8 V to 3.6 V with Microchip's eXtreme Low-Power (XLP) technology for battery-friendly designs. An 8-bit PIC microcontroller is a single-chip computer based on a modified Harvard architecture with separate program and data buses, popular for deterministic real-time control in cost-sensitive and low-power embedded applications. Within Microchip's portfolio, PIC16 sits between the baseline PIC10/12/16 families and the 16-bit dsPIC line, and the LF prefix denotes the low-voltage variant for 1.8 V operation. Key features include two 10-bit PWMs (a 16-bit PWM is also available via the CCP module), a 12-bit ADC with Computation (ADCC), an 8-bit DAC, two comparators, a Complementary Waveform Generator (CWG), and configurable logic cells. Communication peripherals include EUSART, SPI and I2C. The 12-bit ADCC supports automated averaging, threshold comparison, and oversampling, reducing CPU overhead for sensor acquisition. The PIC16LF18444 integrates Core Independent Peripherals (CIPs) that operate without CPU intervention - the CWG, configurable logic, and ADCC can implement motor control, lighting, and signal conditioning in hardware. The XLP features deliver nanoWatt sleep currents below 50 nA typical in deep sleep with retention, making the device suitable for energy-harvesting or battery-powered sensor nodes. Typical applications include IoT sensor nodes, low-power wireless sensor transmitters, battery-powered home automation, LED lighting controllers, consumer appliances, and small motor or fan control stages. The wide 1.8 V to 3.6 V supply range lets the device run directly from a single lithium cell or two AA batteries. When designing with this part, budget carefully for the 1.8 V minimum supply - the 32 MHz operation requires at least 3.0 V VDD, while full 32 MHz core speed and ADC performance are only guaranteed above 3.0 V. Use Microchip's MPLAB X IDE with the XC8 compiler for firmware development.

PIC16LF18444-I/GZ - 8-bit XLP MCU, 7KB Flash, 32MHz | Microchip
PIC16LF18444-I/GZ

PIC16LF18444-I/GZ - 8-bit XLP MCU, 7KB Flash, 32MHz | Microchip

The Microchip Technology PIC16LF18444-I/GZ is an 8-bit PIC® XLP™ microcontroller built around an enhanced mid-range core running at up to 32MHz, delivering 7KB of Flash program memory and 512B of RAM in a compact 20-pin UQFN (4x4) package. The 'LF' prefix indicates a wide 1.8V to 3.6V supply range paired with eXtreme Low-Power (XLP) technology, while the 'I' suffix denotes the -40°C to +85°C industrial temperature grade. An 8-bit microcontroller (MCU) is a single-chip computer optimized for embedded control tasks: a CPU, non-volatile program memory, volatile data memory, and a fixed set of peripherals (timers, ADCs, communication ports) integrated onto one die. The 'PIC' architecture sits in the hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. Designers choose 8-bit MCUs like the PIC16LF18444 for low-cost, low-power, deterministic interrupt-driven applications where a 32-bit Cortex-M would be overkill and the integrated analog peripherals reduce BOM cost. Key features of the PIC16LF18444-I/GZ include a 12-bit ADC with Computation (ADCC) for averaging and automated threshold detection, an on-chip 5-/10-bit DAC, two PWM peripherals, a Comparator, a Complementary Waveform Generator (CWG), and EUSART plus SPI and I²C interfaces. The family supports Core Independent Peripherals (CIPs) that offload tasks like touch sensing, signal conditioning, and motor control from the CPU, lowering active time and total energy consumption in battery-powered systems. Architecturally, the PIC16LF18444 uses a 14-bit instruction-word modified Harvard design with a hardware stack and vectored interrupts, allowing deterministic interrupt latency for real-time control. XLP technology brings sleep currents in the microamp range and a Windowed Watchdog Timer (WWDT) that can keep a sensor node running for years on a single coin cell. The 20-pin UQFN (4x4 mm) footprint with exposed pad enables thermally efficient, high-density PCB layouts suited to space-constrained wearables and IoT modules. Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, low-power wireless sensor end-points, fan/temperature control loops, and small home appliances. The combination of eXtreme Low-Power modes and rich analog peripherals makes the part especially attractive for designers targeting years of battery life without sacrificing signal-acquisition accuracy. When designing with the PIC16LF18444-I/GZ, observe the recommended decoupling scheme (100nF plus 1µF or larger bulk on VDD) and tie unused I/O pins to defined logic levels to minimize leakage during sleep. The exposed thermal pad on the UQFN-20 must be soldered to the PCB ground plane for mechanical reliability and thermal performance; skipping this pad can lead to lifted parts during reflow rework.

PIC16LF18444-I/SO - 8-bit XLP MCU, 7KB Flash, 32MHz, SOIC-20 | Microchip
PIC16LF18444-I/SO

PIC16LF18444-I/SO - 8-bit XLP MCU, 7KB Flash, 32MHz, SOIC-20 | Microchip

The Microchip Technology PIC16LF18444-I/SO is an 8-bit PIC® microcontroller featuring the enhanced mid-range PIC16 CPU core, 7KB (4K x 14 words) of self-programmable Flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM, housed in a 20-pin SOIC (300 mil) package. It operates at up to 32 MHz across a 1.8 V to 3.6 V supply range, and is qualified for the industrial -40 °C to +85 °C temperature grade. The 'I' in the suffix denotes the industrial temperature range and the /SO denotes the 20-lead SOIC package. An 8-bit PIC microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile Flash program memory, data RAM, EEPROM, and a rich set of analog and digital peripherals around a RISC architecture optimized for deterministic real-time control. PIC16LF184xx parts sit in the PIC16 family hierarchy (8-bit MCU -> PIC16 family -> enhanced mid-range core -> XLP low-power family), and they are designed for battery-powered and energy-harvesting applications thanks to eXtreme Low-Power (XLP) technology that delivers nanoWatt sleep currents and active current in the microamp range. Key differentiating specifications include a 12-bit ADC with Computation (ADC2), a 5-bit DAC, two PWM modules with complementary waveform generation (CWG), a comparator, EUSART, SPI and I²C peripherals, and Core Independent Peripherals (CIPs) that offload tasks from the CPU. The integrated 32 MHz internal oscillator and Memory Access Partitioning (MAP) feature let designers balance code protection against firmware update flexibility, while the Device Information Area (DIA) provides on-chip calibration data for temperature sensors and internal references. Architecturally, the LF18444 uses a 14-bit instruction word, a hardware stack, and an instruction set optimized for C-compiled code (XC8). The CIP ecosystem — CWG, NCO, CLC, PWM, and configurable logic — allows complex timing and signal-conditioning functions to run without CPU intervention, lowering power and freeing the core for application logic. This combination of analog density, CIPs, and XLP is what differentiates the LF18444 from older PIC16 baseline parts. Typical applications include portable industrial sensors, low-power IoT edge nodes, battery-powered metering, LED lighting controllers, and general-purpose user-interface boards that need USB-free serial communication. For designs that require a touch-down UART module (DMX/EL wire), the related PIC16LF18446 is a more appropriate choice within the same family. A key design consideration is the 1.8–3.6 V supply window of the 'LF' variant. For systems powered from a 5 V rail or from a single-cell Li-ion above 3.6 V, the designer must either add a pre-regulator or select the PIC16F18444 (5 V) variant. The exposed pad on the SOIC package is not present; thermal dissipation at 32 MHz is small, but exposed-pad DFN/QFN variants of the same die exist for higher-pin-count boards. This page synthesizes Microchip datasheet parameters, distributor pricing as of 2026-09-24, and drop-in alternatives (same SOIC-20 footprint, same PIC16LF18444-family die) that are not listed side-by-side on the Microchip product brief, giving engineers a single source for selection, AE-pairing, and procurement decisions.
