The Microchip Technology PIC18LF26J13-I/ML is an 8-bit PIC18 XLP nanoWatt microcontroller with 64KB Flash, 4KB RAM, and a 12-bit ADC, housed in a 28-pin QFN (ML) 6x6 mm package with exposed pad. It operates at up to 48 MHz (12 MIPS) from a 2.0-3.6 V supply and is positioned for low-power, cost-sensitive embedded designs in the PIC18 J-series family. An 8-bit microcontroller (MCU) is a self-contained computing element integrating a CPU core, program memory, RAM, peripherals, and I/O on a single die. The PIC18 family is Microchip's high-performance 8-bit line, while the LF prefix denotes the low-voltage F-type Flash core and the XLP (eXtreme Low Power) nanoWatt designation indicates optimized sleep modes for battery-powered products. Within the broader taxonomy, the PIC18LF26J13 sits under: microcontroller -> 8-bit MCU -> PIC18 family -> PIC18 J-series -> low-power sub-family. Key features include 64 KB (32K x 16) of self-programmable Flash program memory, 4 KB RAM, 1024 bytes of EEPROM, a 10-channel 12-bit ADC, multiple timers (TMR0/1/2/3), 2 capture/compare/PWM modules, 2 UART, 1 SPI, 1 I2C, and nanoWatt technology with deep sleep current down to a few nanoamps. The 28-QFN package exposes a thermal pad for improved heat spreading in space-limited layouts. Technically, the J-series core adds hardware multiply and C-runtime-friendly addressing modes that close the historical gap between PIC16 and 32-bit cores, while retaining the deterministic single-cycle instruction pipeline. The 12 MIPS throughput at 48 MHz gives ample headroom for sensor fusion, USB-free protocol stacks, and human-interface firmware. Typical applications include low-power IoT sensor nodes, battery-powered medical monitors, consumer appliances, USB HID class replacements, and industrial control panels. Designers select this part when EEPROM, a 12-bit ADC, and rich serial peripherals are required in a small 6x6 mm outline. When laying out the board, tie the exposed pad (EP) to ground with at least 8 thermal vias on the top layer to keep junction temperature in spec; do not skip the 0.1 uF decoupling pair on VDD/AVDD plus a 10 uF bulk capacitor. Use the ICD 3 or PICKit 4 for in-circuit debug, since the J-series only supports ICSP programming via PGEC1/PGED1.

The wide 2.0V-3.6V supply range with internal 3.3V regulation supports single-cell Li-ion or two-AA battery designs. Typical applications include USB peripherals, sensor hubs, low-power wireless sensor nodes, industrial data loggers, HID-class USB devices, and consumer electronics with USB connectivity. The combination of integrated USB, deep-sleep nanoWatt XLP modes, and rich peripherals makes it well-suited for cost-sensitive USB-aware embedded products. When designing with this device, note that the 28-SOIC package is the most common variant; for USB designs with dedicated D+/D- pins routing, follow the datasheet's PCB layout recommendations for the integrated 3.3V regulator. Designers should also verify the 'LF' supply voltage window (2.0V-3.6V) versus the non-LF 'F' variant (down to 2.0V) when selecting parts for 5V-tolerant applications.

PIC18LF26J53T-I/ML

PIC18LF26J53T-I/ML - 64KB Flash USB MCU, 28-QFN | Microchip

The Microchip PIC18LF26J53T-I/ML is a low-power 8-bit PIC microcontroller from the PIC18LFxxJ53 family, featuring 64 KB of Flash program memory, 4 KB of RAM, and an integrated full-speed USB 2.0 transceiver. Housed in a 28-pin QFN package (ML, 6x6 mm), the device operates from 2.0 V to 2.75 V and delivers up to 12 MIPS throughput. The 'LF' prefix denotes the low-voltage/F-range silicon revision optimized for portable and battery-powered designs, while the 'T' suffix indicates tape-and-reel packaging. What is a PIC18 microcontroller? PIC18 microcontrollers are 8-bit RISC microcontrollers from Microchip built on a Harvard architecture with a modified instruction set. They integrate Flash program memory, RAM, EEPROM, peripheral modules, and in many variants a USB transceiver, all on a single die. In the system hierarchy, a PIC18 sits below 16-bit dsPIC and 32-bit SAM/ARM Cortex-M parts but offers excellent code density, mature tooling, and integrated peripherals at very low cost. Key features of the PIC18LF26J53 include a 12-bit A/D converter with up to 10 channels, multiple serial interfaces (I2C/SPI/UART), an Enhanced USART, a 10-bit DAC reference, internal 31 kHz and 8 MHz oscillators, and up to 22 I/O pins. The integrated USB 2.0 full-speed transceiver with on-chip pull-ups simplifies USB device designs by eliminating external transceivers and reducing BOM cost. The 12 MIPS execution rate supports real-time control loops and USB enumeration without bottlenecks. The architecture combines a 16-bit instruction word with an 8-bit data path, an 8x8 hardware multiplier, a 4-deep FIFO for the A/D converter, and a priority interrupt controller. The internal voltage regulator of the J53 family can be configured for 2.5 V or 3.3 V core operation, and the wide I/O tolerance allows direct interface to 5 V peripherals in mixed-voltage systems when the regulator is properly bypassed. Typical applications include USB peripherals (HID, CDC, MSD), battery-powered sensor hubs, home automation controllers, low-cost data loggers, and small industrial HMI panels where the USB interface is the primary desktop-side connection and on-board peripherals drive actuators and displays. The 28-QFN footprint is also footprint-compatible with several other PIC18F2xJ53 variants, enabling easy migration across the family. When designing with this part, ensure the VUSB pin is connected to the USB VBUS through the internal pull-up configuration (per datasheet section 2.0 'Typical Application Connection'), and place the decoupling capacitor on VCAP/VDDCORE within 5 mm of the pin. A pull-up on MCLR is required if the device is used in production; tying MCLR directly to VDD prevents reliable reset behavior.

The core runs at up to 64MHz, delivering up to 16 MIPS while operating from a 1.8V to 3.6V supply, which makes it ideal for battery-powered designs that demand both computational throughput and low quiescent current. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and programmable peripherals into one package. The PIC18 family is Microchip's high-pin-count, high-memory 8-bit line; nanoWatt XLP is the marketing label for the power-management features that allow deep-sleep currents in the sub-microamp range. Within the broader taxonomy, the PIC18LF26K22 occupies the LDO-class low-voltage LF slot of Microchip's 8-bit portfolio, sitting between the legacy PIC16 mid-range parts and the 16-bit PIC24/dsPIC families.

The wide operating voltage range of 1.8V to 3.6V lets the part run directly from a single Li-Ion cell or two AA batteries, while peripherals like the RTCC and Ultra-Low-Power Wake-up keep standby consumption measured in nanoamps. Architecturally, the PIC18LF26K22 uses a 16-bit modified Harvard architecture with a hardware multiply and 31-level hardware stack, distinguishing it from the 14-bit PIC16 mid-range parts and giving software developers higher code density per instruction. The 28-pin QFN package exposes the full peripheral set including up to 28 ADC channels through digital I/O reassignment, making the silicon equally suited for sensor aggregation, user I/O, and motor control roles in compact layouts. Typical applications include wearable health and fitness devices, low-power wireless sensor nodes, battery-powered metering, USB-to-UART bridge dongles, and general-purpose consumer/industrial control. The combination of 64KB Flash and nanoWatt XLP makes it a frequent choice for designs that need room for a USB stack, a wireless protocol, or a graphical HMI on a long-life battery. When designing with the E temperature grade, observe the -40C to +125C ambient window and follow the in-circuit serial programming (ICSP) timing diagrams from the Microchip datasheet when a debugger/programmer header is added. For engineering reviews, note that the 'LF' prefix indicates 1.8V-3.6V operation; migrating to the PIC18F26K22 version is the standard upgrade path when a 5V-tolerant 1.8V-5.5V supply rail is needed instead.

It operates over a supply voltage range of 4.2V to 5.5V, with 34 digital I/O pins, an integrated 10-bit ADC, multiple PWM modules, and standard communication peripherals including UART, SPI, and I2C. A PIC microcontroller (MCU) is a compact programmable processor that integrates CPU, memory, and peripherals on a single silicon die. PIC microcontrollers from Microchip sit at the intersection of 8-bit microcontrollers -> RISC microcontroller -> embedded controller -> semiconductor IC, and have been a foundational building block of embedded systems since the 1990s. They are widely used in applications where deterministic behavior, low power, and a mature toolchain (MPLAB X IDE, XC8 compiler) are valued. Key features of the PIC18LF26K22 family include nanoWatt XLP technology for sleep currents down to the nanoampere range, peripheral flexibility with multiple capture/compare/PWM modules, an enhanced 8/16-bit timer block, and a wide operating temperature range. The 'LF' prefix designates the wide-voltage-range silicon variant, while the 'E' suffix indicates the Extended (industrial) temperature grade of -40C to +125C.

PIC18LF26K22-E/SS - 64KB Flash 8-bit nanoWatt XLP MCU | Microchip

The Microchip PIC18LF26K22-E/SS is a low-power, high-performance 8-bit PIC microcontroller with 64KB Flash, 3,968 bytes of RAM, and a 48 MHz internal oscillator, housed in a 28-pin SSOP package. The LF variant operates from a wide 1.8V to 3.6V supply range and integrates nanoWatt eXtreme Low Power (XLP) technology that drops sleep current to a few tens of nanoamps. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and programmable peripherals on one die. The PIC18 family sits in the 8-bit RISC category of MCUs, which trades raw clock speed for deterministic instruction timing, predictable interrupt latency, and a compact C-friendly instruction set. PIC18 devices are typically chosen over 16-bit and 32-bit parts when BOM cost, code simplicity, and ultra-low sleep current are more important than arithmetic throughput. Within the Microchip portfolio, PIC18 belongs to the larger microcontroller -> embedded MCU -> semiconductor taxonomy. Key features of the PIC18LF26K22-E/SS include 64KB (32K x 16) self-programmable Flash, 256 bytes of EEPROM, a 12-bit ADC with up to 19 channels, two Enhanced USART modules, two MSSP (SPI/I2C) peripherals, and a 5-bit DAC. The device also supports capacitive touch sensing via the mTouch framework and integrates a 16-bit timer/counter with capture/compare. Architecturally the PIC18LF26K22 uses an 8-bit RISC core with hardware multiply, a 16-bit instruction word, and a vectored interrupt controller. The wide operating voltage window (1.8-3.6V) makes it ideal for direct connection to a single-cell Li-ion or 2xAA battery, while the nanoWatt XLP sleep modes extend battery life in intermittently active products. Typical applications include battery-powered sensor nodes, low-cost consumer appliances, touch-interface front panels, industrial control modules, and portable medical devices such as glucose meters or spirometers. The combination of EEPROM, multiple serial interfaces, and rich analog peripherals enables single-chip implementation of many mixed-signal embedded designs. When designing with this part, keep in mind that the "E" suffix denotes the -40C to +125C extended temperature grade and the "LF" prefix denotes the low-voltage core variant. Decoupling the AVDD/AVSS analog rails separately from VDD/VSS reduces ADC noise, and unused I/O pins should be configured as outputs low to minimize sleep current. Designers migrating from the PIC18F26K22 (F = 1.8-5.5V) need to re-validate analog performance, because several analog specs degrade at the LF lower input rail.

PIC18LF26K22-I/SO

PIC18LF26K22-I/SO - 64KB Flash 8-bit MCU XLP 28-SOIC | Microchip

The Microchip Technology PIC18LF26K22-I/SO is a low-power, high-performance 8-bit PIC microcontroller from the PIC18 K22 family with 64KB Flash, 3,968 bytes SRAM and 1,024 bytes EEPROM, housed in a 28-pin SOIC package rated for the industrial -40C to +85C temperature range. The device runs at up to 64 MHz (16 MIPS instruction throughput), integrates a 10-bit ADC up to 17 channels, multiple Enhanced USART, MSSP and CCP/ECCP peripherals, and qualifies for the -LF 1.8V-3.6V voltage variant suited to single-cell Li-Ion designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM/EEPROM) and a configurable set of peripherals - ADC, timers, communication interfaces and GPIO - on one piece of silicon. MCUs sit at the lowest tier of the embedded computing hierarchy, below microprocessors (MPU) and far below SoCs, and are the workhorses of embedded designs because they consolidate control logic, I/O and signal conditioning into one programmable part. The PIC18 family is Microchip's 8-bit baseline architecture, and the K22 sub-family specifically targets low-power (nanoWatt XLP) portable and battery applications. Key features include nanoWatt XLP extreme-low-power technology with multiple sleep modes down to sub-microampere leakage, 25 general-purpose I/O pins with interrupt-on-change, two Enhanced USART modules supporting LIN and IrDA, two MSSP ports (I2C/SPI), three CCP plus one ECCP module for PWM/motor control, and a 10-bit ADC with up to 17 channels and automatic acquisition. The -LF voltage variant operates from 1.8V to 3.6V. Architecturally, the PIC18LF26K22 uses a RISC Harvard-style core with a 16-bit instruction word, an 8-bit data path, and a hardware multiplier that simplifies time-critical math versus pure 8-bit accumulator cores. The 64 MHz Fosc derives from an internal 16 MHz HFINTOSC plus a 4x PLL block, allowing firmware to tune CPU speed on the fly via OSCTUNE to trade throughput for current consumption. Typical applications include low-power sensor nodes, handheld instrumentation, USB-to-UART bridges (with a companion MCP2200), small motor control, battery chargers, and industrial control panels that need 5V-tolerant GPIO or XLP sleep profiles. Design consideration: choose the -LF (1.8V-3.3V) variant rather than the -F (1.8V-5.5V) when your design runs from a single Li-Ion or two AA cells; this trade-off costs 5V tolerance but saves tens of microamperes in active run current. This page synthesizes distributor pricing, drop-in same-package alternatives (PIC18LF26K22 family members and PIC18F26K22-I/SO), datasheet-cited electrical parameters, and practical design notes not found in a single distributor listing, giving engineers an AEO-friendly comparison surface for component selection.

It operates across a wide 1.8V to 3.6V supply range with up to 64MHz CPU performance (16 MIPS at 64MHz internal), making it suitable for both battery-powered and line-powered embedded designs. The "LF" prefix designates the low-voltage F-variant with extended nanoWatt XLP features. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O into one package. The PIC18 family uses Microchip's enhanced 8-bit RISC architecture with hardware multiplier and C-friendly design. Within the broader taxonomy, the PIC18LF26K22 sits as: microcontroller -> 8-bit MCU -> PIC18 family -> PIC18 "K22" sub-family -> PIC18LF26K22 (low-voltage, 28-pin, 64KB Flash). It is the foundation of millions of embedded products in consumer, industrial, and automotive-grade (with Q-graded parts) applications. Key differentiating features of the PIC18LF26K22 include the nanoWatt XLP technology with deep-sleep current in the nanoamp range, integrated mTouch capacitive sensing peripherals, two Enhanced USART modules, two MSSP (SPI/I2C) ports, two CCP/ECCP modules, a 12-channel 10-bit ADC, and four 8-bit timers plus five 16-bit timers. The CTMU peripheral enables capacitive touch and time measurement without external components. The on-chip 64MHz internal oscillator reduces BOM by eliminating an external crystal in many designs. Typical applications include low-power battery sensor nodes, USB HID peripherals (when paired with the F-variant's USB module), home appliances, motor-control BLDC/PMSM drivers using ECCP, capacitive touch keypads with mTouch, and industrial IoT edge nodes. The wide operating voltage (1.8V-3.3V typical, 3.6V max) lets a single part cover 2xAA, Li-ion, and 3.3V regulated rails. A key design consideration: at 64MHz and 3.3V the core draws ~10mA (typical), so coin-cell designs must use nanoWatt XLP sleep modes (down to ~20nA). For multi-rail systems, the brown-out reset (BOR) and PWRT timers should be enabled to ensure deterministic startup. The I/SS package is the industrial (-40C to +85C) temperature grade with SSOP-28 footprint.

Architecturally, the PIC18LF26K22 uses an enhanced Harvard architecture with separate program and data buses, a 16-bit instruction word, and a rich instruction set. The LF process is optimized for low-voltage operation, which is why the datasheet specifies 1.8V-3.6V (compared to the F variant's 2.3V-5.5V range). Peripherals XLP variants reduce active current below typical PIC18 levels, making them ideal for battery-powered applications. Typical applications include IoT sensor nodes, battery-powered metering devices, low-power remote controls, HVAC thermostats, and portable industrial instruments. Anywhere a coin-cell or two-AA battery must last years, this MCU's XLP features become attractive. When designing with this device, choose the LF variant (1.8V-3.6V) if the system is battery-powered or uses a regulated 3.3V rail; choose the F variant if a 5V rail is available without regulation.

The "LF" prefix denotes the extended low-power (XLP) family, optimized for battery-operated and energy-harvesting designs where quiescent current in nanoampere ranges is mandatory. The device operates from 1.8 V to 3.6 V (LF variant) and supports up to 16 MIPS at 64 MHz. It features Core Independent Peripherals (CIPs) such as the Complementary Waveform Generator (CWG), Windowed Watchdog Timer (WWDT), and Cyclic Redundancy Check with Memory Scan (CRC/SCAN) that offload tasks from the CPU and improve deterministic real-time response. The 10-bit ADC2 includes hardware accumulation, averaging, threshold detection, and automatic channel scanning, reducing firmware overhead for sensor-array applications. Typical applications include IoT sensor nodes, battery-powered instrumentation, home automation controllers, low-power wireless sensor platforms, and consumer appliances. The integrated ZCD, CWG, and analog peripherals make it well suited for SMPS control loops and motor/lighting control where deterministic hardware response is required. Designers should review the device's power-budget calculator and clock-tree configuration in MPLAB X IDE to balance active current, sleep current, and wake-up latency. The 28-pin SPDIP footprint supports breadboard and through-hole prototyping, while surface-mount variants (SOIC/SSOP/QFN/ML) of the same die are available for production reflow assembly. This page synthesizes distributor pricing, drop-in same-family alternatives from Microchip, and practical design notes that supplement - but do not replace - the manufacturer datasheet and the MPLAB XC8 compiler documentation.

PIC18LF26K40-E/SS

PIC18LF26K40-E/SS - 64KB Flash XLP 8-bit MCU, SSOP-28 | Microchip

The Microchip Technology PIC18LF26K40-E/SS is a 28-pin, ultra-low-power (XLP) 8-bit PIC microcontroller built on the enhanced mid-range PIC18 core, integrating 64KB of Flash program memory, 4KB of SRAM, and 256 bytes of EEPROM in a 28-SSOP package. It executes instructions at up to 64 MHz from a 1.8V-3.6V supply, with peripheral-rich integration including a 10-bit ADC with computation (ADC2), a 5-bit DAC, comparators, configurable logic cells (CLC), complementary waveform generator (CWG), windowed watchdog timer (WWDT), CRC/SCAN, zero-cross detect (ZCD), and peripheral pin select (PPS) for flexible signal routing. An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data bus width, internal program memory, RAM, and integrated peripherals like ADC, timers, and communication interfaces. Within the MCU taxonomy, the PIC18LF26K40 belongs to the PIC18 family -> 8-bit PIC microcontrollers -> microcontrollers -> microcontrollers and processors -> semiconductor ICs, positioning it for general-purpose embedded control rather than high-performance DSP workloads. Key differentiating features include nanoWatt XLP technology for sub-µA sleep currents that extend battery life, eXtreme Low-Power (XLP) modes with typical <100 nA sleep draw, PPS for remapping digital peripherals to nearly any I/O pin (reducing PCB layout constraints), and Core Independent Peripherals (CIPs) such as CWG and WWDT that operate without CPU intervention. The 'LF' prefix denotes the low-voltage (1.8V-3.6V) variant designed for battery-powered and energy-harvesting systems. Architecturally, the device uses a 16-bit instruction word with an 8-bit data path, hardware multiply, and a vectored interrupt controller supporting prioritized interrupts. The integrated high-frequency oscillator and PLL eliminate external crystals for many timing needs, while the IDLE/DOZE/PMD power-management modes let developers trade peripheral activity against current draw at runtime. Typical applications include IoT sensor nodes, battery-powered remote controls, low-end consumer electronics, industrial sensor interfaces, and automotive body controllers. Designers select this MCU when they need generous Flash/RAM, robust I/O count, and proven low-power PIC18 toolchain support. Design consideration: leverage PPS to remap EUSART/SPI/I2C to any available pin, simplifying PCB routing; always place the ICSPDAT/ICSCLK pins to accessible test points for in-circuit programming and debugging. This page consolidates distributor pricing tiers (as of 2026-09-28), verified drop-in alternatives (same SSOP-28 package), and practical design notes synthesized from Microchip datasheets not commonly seen on distributor listings.

PIC18LF26K40-I/MV

PIC18LF26K40-I/MV - 64KB Flash 8-Bit XLP MCU | Microchip

The Microchip Technology PIC18LF26K40-I/MV is an 8-bit PIC18 microcontroller built on the eXtreme Low-Power (XLP) platform, delivering up to 64 MHz operation with 64 KB of Flash program memory, 4 KB of SRAM, and 256 bytes of EEPROM in a compact 28-pin UQFN (MV) package measuring 4x4 mm. A microcontroller is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals; the PIC18 family is Microchip's 8-bit architecture that combines RISC-like efficiency with rich on-chip peripherals for embedded control. Within that hierarchy, the LF variant denotes the low-voltage core (1.8 V to 3.6 V operation), the K40 generation adds Core Independent Peripherals and 5 V tolerant I/O, and the "26" pin-count signals a 28-pin package option. This positions the LF26K40 as a power-aware general-purpose MCU spanning the PIC18 -> 8-bit MCU -> microcontroller -> embedded IC taxonomy. Key specifications include a 64 MHz internal oscillator (16 MIPS instruction throughput), a 10-bit ADC with up to 24 channels, a 5-bit DAC, complementary waveform generators (CWG), hardware limit timers (HLT), windowed watch-dog timer (WWDT), zero-cross detection (ZCD), CRC/SCAN, and peripheral pin select (PPS) for flexible signal routing. The device operates from 1.8 V to 3.6 V with nanoWatt XLP sleep currents that suit battery-powered designs. The architecture couples a 16-bit wide instruction path with an 8-bit data path, delivering deterministic interrupt latency while keeping peripheral interaction intuitive. The XLP technology integrates multiple low-power modes (sleep, doze, idle, peripheral module disable) with retention RAM and a RTCC, allowing designs to draw microamps while still maintaining real-time responsiveness. Typical applications include consumer IoT sensor nodes, battery-powered medical wearables, industrial HMI keypads, low-power wireless sensor hubs, and home appliance user-interface boards. The wide 1.8-3.6 V supply range suits single-cell Li-ion or 2x AA operation without additional boost converters. When selecting this part, verify that your code base targets the K40 errata and PPS register set because the PPS subsystem differs from earlier PIC18F K-series devices. Designers transitioning from PIC18F25K22 or PIC18F26K22 should recompile against the XC8 K40 device pack to avoid peripheral library mismatches. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design considerations not bundled in the manufacturer datasheet, giving engineers a faster path to a validated 8-bit design.
