Key features include ten 10-bit ADC channels with auto-acquisition, two enhanced USART modules, two MSSP ports for SPI / I2C, a 10-bit PWM with enhanced capture/compare, nanoWatt Technology for power-managed sleep modes drawing as low as 100 nA in Sleep, and 25 I/O pins with interrupt-on-change capability. The RISC-style PIC18 core provides 77 single-word instructions, interrupt-driven operation, and a hardware multiplier for 8x8 single-cycle multiplications. Typical applications include low-power sensor nodes, industrial control panels, consumer appliances, USB/serial bridge adapters, motor control with back-EMF sensing, and battery management front-ends. Its small 6x6 mm QFN footprint suits compact designs while exposing enough peripheral density for human-machine interface (HMI) and instrumentation tasks. When designing with this part, verify that the chosen debugger/programmer (e.g. PICkit 3, ICD 3, MPLAB SNAP) supports the PIC18F/LF family and that your PCB layout exposes the PGC/PGD ICSP pins plus MCLR/Vpp for in-circuit serial programming. Consider migrating to a PIC18F25K22 or PIC18F26K22 if more memory, a richer peripheral set, or extended voltage tolerance is required.

The integrated Motion Feedback Module (MFM) on this family can simplify Hall-sensor or BEMF signal decoding for sensored BLDC commutation. In the system hierarchy, it typically sits between a sensor / power-driver stage and the host processor, running real-time control firmware from on-chip Flash. When designing with this device, pay attention to the QFN-28 exposed pad - it must be soldered to a sufficiently large copper pour for thermal dissipation and electrical grounding. Decoupling should place 100nF and 10uF caps close to VDD/VSS, and the ICSP/ICD pins must be reserved for in-circuit programming. Pair the MCU with a Microchip TC4427 or TC427 driver if the PWM outputs need to drive power MOSFETs directly.

Code developed on the PIC18F23K22 (5V) variant migrates directly to the LF (3.3V) variant, allowing a single firmware image to target multiple rails. The device is suitable for battery-powered applications that require low sleep current combined with sufficient MIPS to handle communication stacks. Typical applications include battery-powered sensor nodes, capacitive touch user interfaces, low-power wireless companion MCUs, industrial sensor conditioning, and USB-to-UART bridges using the EUSART. The -40C to +125C operating range and nanoWatt XLP modes extend battery life in remote or energy-harvesting designs. When designing with this part, ensure the exposed pad on the QFN is soldered to a sufficiently large copper pour for thermal and electrical ground performance, and configure the configuration bits for the desired oscillator mode and watchdog timer behavior. The LF variant must not be powered above 3.6V - use the PIC18F23K22 (5V tolerant) variant for higher rails. This page consolidates distributor pricing, pin-compatible alternatives in the same 28-QFN footprint, and design notes beyond the manufacturer datasheet to assist engineers evaluating the PIC18LF23K22-E/ML for embedded designs.

PIC18LF23K22-E/MV

PIC18LF23K22-E/MV - 8KB Flash 16-I/O XLP MCU | Microchip

The Microchip PIC18LF23K22-E/MV is an 8-bit PIC18-family RISC microcontroller with 8KB Flash program memory, 768 bytes RAM, and 256 bytes EEPROM, housed in a 28-pin UQFN EP (6 mm x 6 mm) package with exposed pad. It operates from a 2.0V to 5.5V supply at up to 25 MHz (or 48 MHz internal oscillator per datasheet headline) and provides 16 digital I/O pins, making it a low-power, high-performance device aimed at battery-powered and energy-harvesting applications. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and programmable peripherals on a single die. The PIC18LF23K22-E/MV sits inside Microchip's nanoWatt XLP (eXtreme Low Power) product line - meaning it ships with deep-sleep, sleep, idle, and dozing modes that drop core current into the nanoamp range. As an 'LF' (low-voltage) variant, it is specified for 2.0-5.5V operation, distinguishing it from the 'F' (standard) sibling which starts at 1.8V but targets higher temperatures and slightly different oscillator behavior. Key features include 8KB self-programmable Flash, 768 bytes SRAM, 256 bytes data EEPROM, 10-bit ADC up to 19 channels, multiple serial peripherals (EUSART, MSSP for SPI/I2C), and nanoWatt XLP power management with claimed sleep currents below 20 nA typical. The 28-pin UQFN EP package with exposed thermal pad offers strong thermal performance and a compact 6 mm x 6 mm footprint suitable for dense PCB layouts. The architecture is a Harvard-style RISC core with a hardware multiplier, 16-bit instructions, and a deterministic instruction pipeline. The 25 MHz CPU clock combined with a 4-cycle instruction cycle yields an instruction throughput of 6.25 MIPS, with hardware peripheral engines offloading timers, capture/compare, PWM, and 10-bit ADC conversion - giving designers deterministic real-time behavior for motor control, sensor sampling, and power-converter feedback loops. Typical applications include battery-powered IoT sensor nodes, low-power wireless remote controls, HVAC and smart-building sensors, portable medical monitoring accessories, and industrial metering where extended battery life, deterministic peripheral response, and small PCB footprint matter. The integrated 10-bit ADC, EUSART, and MSSP peripherals cover most sensor-bus and wired-comms requirements without an external bridge chip. When designing with this device, place the 0.1 uF decoupling capacitor within 2-3 mm of each VDD pin and a bulk capacitor near the exposed pad for ground return, as the QFN's bottom pad is the primary thermal and electrical path to GND. Always configure the LF variant's voltage regulator in full-PLL-bypass mode for sub-3.3V rails to keep sleep current in the nanoWatt XLP regime.

The PIC18LF23K22 uses Microchip's nanoWatt XLP technology to deliver sleep currents in the sub-100 nA range and a typical active current below 1 mA at low clock speeds. Architecture is based on the enhanced PIC18 RISC core with a 16-bit instruction word, hardware multiplier, hardware stack of 31 levels, single-cycle ALU operations and a configurable oscillator block supporting 8 MHz to 64 MHz operation. The integrated voltage regulator, brown-out reset and extended watchdog timer give the LF variant particular resilience in 3.3V-only or battery-driven designs. Typical applications include low-power sensor nodes, hand-held instruments, home appliances, HVAC controls, LED lighting controllers, small motor control, USB/HID peripherals (paired with a USB transceiver), industrial control panels and automotive body modules. The wide SOIC footprint also makes it a popular choice for through-hole-style development boards and educational platforms. When designing with this part, ensure the supply is decoupled with a 100 nF + 10 uF combination near the VDD pin, that the MCLR pin is pulled up via a 10 kohm resistor, and that PGC/PGD lines are reserved for ICSP. The E temperature grade (-40C to +125C) supports industrial and automotive under-hood environments.

PIC18LF23K22-E/SP - 8KB Flash 8-bit XLP MCU | Microchip

The Microchip Technology PIC18LF23K22-E/SP is a 28-pin SPDIP-packaged 8-bit PIC18 microcontroller that delivers 48 MHz CPU performance with 8 KB of Flash program memory and an integrated nanoWatt XLP ultra-low-power peripheral set. The device supports a wide 1.8 V to 3.6 V supply range, with the "L" prefix variant optimized for low-voltage operation, and integrates rich peripherals including up to 25 I/O, multiple Enhanced USART, MSSP (SPI/I2C), 10-bit ADC, comparators, and a hardware RTCC. A PIC (Peripheral Interface Controller) 8-bit RISC microcontroller is a single-chip computer that combines a CPU core, nonvolatile Flash, RAM, and configurable I/O peripherals on a single CMOS die. PIC18 microcontrollers represent the high-end 8-bit tier, featuring an enhanced Harvard architecture, 16-bit instruction words, hardware multiply, and a C-friendly compiler model. They sit at the top of Microchip's 8-bit hierarchy (PIC10/12/16/18 families), used where deterministic real-time control and ultra-low sleep current outweigh raw processing speed. Key features of the PIC18LF23K22 include 8 KB Flash with self-programmability, 768 bytes of RAM, 256 bytes of EEPROM, a 48 MHz internal oscillator, nanoWatt XLP sleep modes drawing as low as 20 nA in deep sleep, hardware RTCC with calendar/timestamp functions, PWM/SCCP capture-and-compare modules for motor control, and Core Independent Peripherals (CIPs) that offload tasks without CPU intervention. The Enhanced USART and MSSP block provides simultaneous SPI/I2C/UART interfaces useful for sensor and wireless module integration. Architecturally, the PIC18LF23K22 uses a 16-bit enhanced instruction set with a 31-level hardware stack and hardware multiply engine. Internal oscillator accuracy is factory-trimmed to ±2% across the full 1.8 V to 3.6 V and -40 °C to +125 °C industrial operating range. Power-management features - including multiple idle and sleep modes, peripheral clock gating, and the nanoWatt XLP analog comparator - enable battery lifetimes measured in years. Typical applications include battery-powered sensor nodes, low-power wireless IoT end-devices, remote control transmitters, medical glucose meters, consumer white goods requiring low standby power, and industrial sensor transmitters. The combination of 48 MHz throughput, 10-bit ADC, and sub-100 nA sleep current makes it well-suited for battery-form-factor products where every milliwatt is accounted for. A key design consideration is that the "L" voltage class supports only 1.8 V to 3.6 V operation; for designs needing 5 V tolerance, the non-L PIC18F23K22 is required. Designers should also enable the WDT and BOR (Brown-out Reset) to ensure recovery from corrupted code paths in remote deployments. Programming is via ICSP using MPLAB SNAP, PICkit, or ICD programmers.

The device exposes 25 general-purpose I/O pins and ships in an industrial -40C to +85C operating range. A PIC (Peripheral Interface Controller) microcontroller is a compact programmable processor that integrates CPU, memory, and peripherals on a single die. The PIC18F/LF family represents Microchip's high-performance 8-bit tier, bridging classic 8-bit simplicity with modern peripheral integration. Within this family, the 'LF' prefix designates low-voltage variants optimized for battery-powered applications, while the 'K22' subfamily introduces nanoWatt XLP technology, making these MCUs ideal for energy harvesting and IoT endpoints where quiescent current in the nanoampere range extends battery life to years. Microcontroller is a hypernym of PIC18, while XLP (eXtreme Low Power) and nanoWatt are Microchip-specific trademarks for the same low-power architecture family. Key features include nanoWatt XLP ultra-low-power technology, an integrated 10-bit ADC with up to 17 input channels, multiple PWM outputs with configurable dead-band, enhanced USART with LIN support, and independent SPI and I2C peripherals.

Programmable undervoltage detection and a windowed watchdog timer add system robustness for industrial and automotive-grade applications. Architecturally, the PIC18LF23K22 employs a RISC-based Harvard architecture with separate instruction and data buses, enabling single-cycle instruction execution. The CPU runs up to 16 MIPS from a 64 MHz internal oscillator block with PLL synthesis. The device integrates a 16 MHz high-frequency internal oscillator plus a 31 kHz low-power oscillator for fail-safe clocking during sleep, eliminating the need for an external crystal in many designs. The ICSP (In-Circuit Serial Programming) interface allows field firmware updates without removing the MCU from the PCB. Typical applications include portable medical devices, wireless sensor nodes, smart meters, remote controls, battery-backed industrial sensors, low-power IoT edge nodes, consumer electronics with capacitive touch interfaces, and automotive body electronics. The wide 1.8V to 3.6V operating range makes it particularly suitable for two- or three-alkaline-cell applications where direct Li-ion compatibility simplifies power design. When designing with this MCU, observe the absolute maximum VDD of 4.0V and consider internal oscillator accuracy versus crystal requirements for timing-sensitive peripherals like LIN or SPI. For lowest sleep current, disable unused peripherals via firmware and use the low-power RTCC oscillator rather than the main system clock during standby.

PIC18LF23K22-I/MV - 8-bit XLP MCU, 8KB Flash, 28-UQFN | Microchip

The Microchip Technology PIC18LF23K22-I/MV is an 8-bit PIC® XLP™ 18K family microcontroller running at up to 64 MHz, integrating 8 KB of Flash program memory (4K x 16), 768 bytes of RAM, and 256 bytes of EEPROM in a compact 28-pin UQFN (4x4 mm) package. The 'LF' prefix denotes a low-voltage variant designed for 1.8 V to 3.6 V operation, paired with nanoWatt XLP™ technology for ultra-low sleep currents below 100 nA in deep sleep. What is a microcontroller (MCU)? An MCU is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one silicon die. The PIC18 family is Microchip's high-performance 8-bit architecture, positioned above the baseline PIC16 and PIC10/12/16 families and below the 16-bit dsPIC and 32-bit PIC32 families. Within the PIC18K sub-family, the 'K' parts target low-power and high-precision analog applications, the 'LF' suffix specifies the 1.8 V–3.6 V extended power range, and the 'F' (non-LF) variants are 5 V tolerant.

Architecturally, the PIC18LF23K22 uses an enhanced Harvard architecture with separate program and data buses, a 16-bit instruction word, and a hardware multiply/divide accelerator. Its 31-level hardware stack and 74 instructions provide deterministic interrupt response, while the peripheral pin-select (PPS) subsystem remaps digital peripherals to any I/O pin to simplify PCB routing on space-constrained boards. Typical applications include battery-powered sensor nodes, low-power IoT edge devices, capacitive-touch user interfaces, small home appliances, and portable medical accessories where low sleep current, small UQFN footprint, and integrated analog peripherals are critical. The wide 1.8–3.6 V operating range allows direct connection to single-cell Li-ion or two-cell alkaline battery stacks. A key design consideration: the 28-UQFN package has an exposed thermal pad that MUST be soldered to the PCB ground plane to meet thermal and mechanical reliability targets; for hand-prototyping or breadboard builds, choose the 28-SPDIP (PIC18LF23K22-I/SP) variant instead. The LF voltage range also requires careful verification of analog reference voltages—using a 5 V reference with a 3.3 V supply will damage the ADC.

Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, low-power wireless sensor platforms (sub-GHz/BLE host MCUs), home-automation controllers, and industrial telemetry. Its nanoWatt XLP sleep current allows multi-year battery life on a single CR2032 coin cell for periodic wake-and-measure duty cycles. When designing with this part, plan a robust brown-out-reset (BOR) and watchdog configuration; the LF core's 1.8 V minimum allows direct Li-ion or 2x AA cell operation without boost converters. Reserve PPS channels early to avoid layout rework.

Within the broader taxonomy, the part is a microcontroller -> 8-bit MCU -> PIC18 family -> nanoWatt XLP -> embedded control IC, making it a workhorse for general-purpose embedded designs. The PIC18LF23K22T-I/ML uses a 16-bit instruction word with 8-bit data path, an internal 16MHz to 64MHz HFINTOSC, and a wide set of clock sources selectable per firmware. Its self-programming Flash, ICSP, and on-chip debug support pair naturally with MPLAB X IDE, MPLAB Code Configurator, and the PICkit 5 programmer/debugger referenced in the Microchip product family page. Typical applications include portable medical devices, IoT sensor nodes, low-power remote controls, consumer HMI panels, and industrial sensor conditioning. When selecting the 'LF' variant, designers trade upper supply headroom (3.6V max) for the lowest active and sleep currents in the family, which is the right trade when the rail is a single Li-ion cell or 2x AA alkaline cells. Design tip: route the exposed pad (EP) to a continuous ground copper pour with multiple thermal vias. Without proper EP grounding, junction-to-ambient thermal resistance rises sharply and ADC readings near full-scale will drift.

Architecturally, the PIC18LF23K22T-I/MV uses an enhanced Harvard architecture with separate program and data buses, a hardware multiplier for 8 × 8 single-cycle operations, and prioritized interrupt handling. The 'LF' prefix indicates the low-voltage / wide VDD range variant; the 'T' suffix denotes Tape and Reel packaging. The 'I' industrial temperature rating and 'MV' package designator round out the part code. Its XLP nanoWatt features include ultra-low-power wake, deep sleep with RAM retention, and multiple idle modes — critical for battery-powered edge devices. Typical applications include portable industrial sensor nodes, low-power IoT edge devices, USB/CDC human-interface peripherals, battery-backed instrumentation, automotive body controllers (sub-systems, not AEC-Q100 powertrain), and small home appliances. The wide 2.0–5.5 V VDD range lets it interface to both 3.3 V and 5 V analog front-ends without level shifting. A key design consideration is decoupling: place one 100 nF ceramic bypass capacitor directly across VDD/VSS as close to the package as possible, plus a bulk 1 µF–10 µF tantalum or ceramic near the regulator. For low-power designs, use the deep-sleep mode with the RTCC running for timekeeping, waking only on interrupt edges. The 28-pin UQFN footprint also requires thermal pad soldering for reliable mass-production assembly.

Key features include 25 analog channels supporting 10-bit ADC, two comparators, a 5-bit DAC, Capture/Compare/PWM (CCP/ECCP) modules, MSSP for SPI/I2C, Enhanced USART, mTouch capacitive sensing, and 25 mA source/sink capable I/O. The wide SOIC-28 footprint provides 23 usable I/O pins, making this part well-suited for mixed-signal embedded applications where board space is at a premium. The PIC18LF23K22 is built on Microchip's high-performance 8-bit core with 16-bit instruction word, single-cycle ALU, and 31-level hardware stack, enabling deterministic interrupt latency. NanoWatt XLP peripherals such as RTCC, deep-sleep brown-out reset (DSBOR), and ultra-low-power watchdog timer allow battery lifetimes measured in years, which is the core differentiator versus the 5V-only PIC18F23K22 sibling. Typical applications include handheld battery-powered instruments, IoT sensor nodes, home automation controls, low-power wireless companion MCUs, and industrial sensor interface boards. The industrial temperature grade makes it usable in factory and outdoor environments. When designing with this part, place a 100 nF decoupling capacitor as close as possible to VDD and a bulk capacitor (1–10 uF) near the IC. Configure unused I/O as outputs tied low to minimize current draw in sleep modes, and follow Microchip application note AN1523 for nanoWatt XLP sleep current optimization.

The 'LF' variant operates across 1.8V to 3.6V, targeting battery-powered and energy-harvesting designs where the standard PIC18F (2.0V to 5.5V) would draw too much quiescent current. The 'T' suffix in the part number designates tape-and-reel packaging, and '/SS' specifies the 28-pin SSOP form factor. According to the manufacturer datasheet, this part combines a 64 MHz internal oscillator with a rich peripheral set including ADC, comparators, PWM, EUSART, MSSP (SPI/I2C) and multiple capture/compare modules. An 8-bit PIC microcontroller is a Harvard-architecture RISC device built around a 16-bit instruction word and an 8-bit data path, providing deterministic interrupt latency, single-cycle multiplication, and a mature MPLAB X IDE toolchain. The PIC18 family sits in Microchip's mid-range performance tier above PIC16 and below dsPIC/PIC32, and is widely used where developers need more peripherals and code space than entry-level MCUs without paying for 32-bit cores. The 'nanoWatt XLP' label refers to Microchip's low-power process enhancements that allow sleep currents in the nanoamp range. Key features of the PIC18LF23K22T-I/SS include: 8KB Flash, 768 bytes SRAM, 256 bytes EEPROM, up to 25 I/O pins, a 10-bit ADC with up to 17 channels, two analog comparators, two CCP modules, one ECCP module, two EUSART modules, one MSSP (SPI/I2C) module, and four 8-bit timers plus three 16-bit timers. The industrial temperature grade (-40C to +85C) supports harsh-environment deployment, and the XLP technology enables typical sleep currents under 100 nA with RTC running. Typical applications for this device include battery-powered IoT sensor nodes, low-power wireless remotes, wearable health monitors, smart meters, and consumer electronics where extended battery life outweighs the need for higher MIPS. The wide 1.8V to 3.6V operating range allows direct connection to single-cell Li-ion or two-AA battery stacks without additional regulation. When designing with this MCU, ensure the supply decoupling network follows the manufacturer reference design with a 100 nF ceramic capacitor close to VDD. The MCLR pin should use the recommended 10 kohm pull-up to VDD for reliable reset behavior. Industrial temperature parts such as the '-I' variant must be selected for any design that will operate below 0C or above +70C.

PIC18LF2410-I/ML - 8-bit 40MHz 16KB Flash MCU 28-QFN | Microchip
PIC18LF2410-I/ML

PIC18LF2410-I/ML - 8-bit 40MHz 16KB Flash MCU 28-QFN | Microchip

The Microchip Technology PIC18LF2410-I/ML is an 8-bit PIC18F-family flash microcontroller running up to 40 MHz (10 MIPS) with 16 KB (8K x 16) of on-chip flash program memory, packaged in a 28-lead QFN (6x6 mm) with an exposed thermal pad. The 'LF' suffix designates the wide-bandgap low-voltage process variant that supports operation from 2.0 V to 5.5 V, while the 'F' (vs. 'LF') siblings operate down to 4.2 V only. The die integrates 768 bytes of RAM, 256 bytes of EEPROM, and the same peripheral set as the rest of the PIC18F2X1X/4X1X family, including a 10-bit A/D converter, multiple timers, USART, MSSP (SPI/I2C), and nanoWatt power management for battery-aware designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable I/O peripherals. The PIC18F family from Microchip uses an enhanced Harvard RISC architecture with a C-compiler-optimized instruction set, single-cycle hardware multiply, and internal oscillator support from 31 kHz to 8 MHz. Within the broader semiconductor taxonomy, an MCU sits between a microprocessor (no on-chip memory or peripherals) and a system-on-chip (SoC, which adds radios and graphics). MCUs are the workhorse of embedded electronics wherever deterministic real-time control is needed at low cost. Key features of the PIC18LF2410 include up to 10 MIPS CPU throughput, an internal oscillator block selectable across 31 kHz to 8 MHz, a fail-safe clock monitor that permits safe shutdown if the primary clock is lost, a watchdog timer with its own dedicated RC oscillator, and nanoWatt Technology for sleep currents below 1 uA in typical applications. Twenty-five general-purpose I/O pins are brought out on the QFN-28, and the device supports in-circuit serial programming (ICSP) via two pins, eliminating the need for a pre-programmed boot loader. The device is well suited to industrial sensing nodes, low-cost sensor signal conditioning, USB-less consumer peripherals, and general-purpose logic replacement where a small PIC18 footprint, low-voltage operation, and 16 KB of code space are sufficient. The 28-QFN exposed pad provides a low thermal resistance path to the PCB copper pour, which helps dissipate heat when the MCU is clocked at the full 40 MHz rate and multiple peripherals are active simultaneously. When designing with this part, ensure the exposed pad is soldered to a continuous ground copper pour to meet the 31 C/W (typical) thermal resistance claim and to provide the lowest-inductance return path for the high-speed internal oscillator. Industrial temperature parts (the 'I' suffix) are rated -40C to +85C, suitable for non-automotive indoor and outdoor industrial enclosures.

It executes instructions at up to 10 MIPS from a 40 MHz oscillator and supports 2.5V, 3.3V, and 5V operation, with the "LF" prefix indicating wide-voltage NanoWatt technology operation across that entire 2.0-5.5V range. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, on-chip Flash program memory, RAM, peripherals, and a CPU core. Within the broader taxonomy, an MCU sits below microprocessor and above discrete logic; the PIC18 family sits in Microchip's mid-range 8-bit portfolio, above PIC10/12/16 baseline parts but below PIC24/dsPIC and PIC32 (32-bit) families. The "LF" series adds NanoWatt sleep modes for battery-powered designs, while the "F" (without L) variant is the 4.2-5.5V-only counterpart. Key features of this device include 16KB (8K x 16) of self-programmable Flash, 768 bytes of SRAM, a 10-bit ADC with up to 10 channels, an internal oscillator selectable from 31 kHz to 8 MHz, fail-safe clock monitoring, and a hardware 8x8 single-cycle multiplier. Enhanced peripherals include multiple USART, MSSP (SPI/I²C), CCP/ECCP modules, and NanoWatt power management with multiple idle and sleep modes drawing microamp-level currents. The exposed thermal pad on the QFN-28 package reduces junction-to-ambient thermal resistance. The PIC18 CPU uses a 16-bit instruction word with an 8-bit data path, a RISC-optimized Harvard architecture, and a C-friendly instruction set that includes a hardware 8x8 multiplier and a hardware divider. Internal oscillator support and fail-safe clock monitor provide clock redundancy, while self-programmable Flash enables in-application firmware updates without an external programmer. Typical applications include industrial sensor interfaces, low-power battery-powered instrumentation, USB/HID peripherals, home appliances, and consumer devices requiring 8-bit processing with mixed-signal I/O. The wide 2.0-5.5V range suits both 3.3V and 5V designs with a single BOM line. The "T" suffix indicates Tape & Reel packaging, and the "-I" indicates an industrial -40°C to +85°C operating temperature range. When designing with this device, validate that the 28-pin QFN land pattern matches your PCB footprint and confirm the -I temperature grade suits your environment. Designers transitioning from PIC18F2410 (non-LF) parts must verify regulator support for sub-4.5V operation.
