PIC18LF4320T-I/PT - 8KB Flash 8-bit MCU 44-TQFP | Microchip

The Microchip Technology PIC18LF4320T-I/PT is an 8-bit PIC18 microcontroller featuring 8KB of Enhanced Flash program memory, 512 bytes of RAM, and a 36 I/O count, housed in a 44-pin TQFP (10x10 mm) package. It operates at up to 40 MHz across a 2.0 V to 5.5 V supply range (industrial temp -40C to +85C) and integrates a 10-bit ADC with nanoWatt Technology power management for energy-sensitive designs. A microcontroller (MCU) is a single-chip computer containing a processor core, non-volatile program memory, working RAM, and a rich set of peripheral interfaces. The PIC18 family sits in the 8-bit RISC hierarchy between baseline PIC10/12/16 devices and the 16-bit PIC24/dsPIC families, occupying the mid-range "high-performance, enhanced Flash" tier. The "F" series introduced Enhanced Flash memory with 100k+ erase/write endurance, making it suitable for field-upgradable firmware. The "LF" voltage variant supports low-voltage operation down to 2.0 V, distinguishing it from standard PIC18F parts that typically require 4.2 V minimum. Key features of this device include the 10-bit Analog-to-Digital Converter (ADC) with multiple input channels, USART and MSSP (SPI/I2C) serial interfaces, Capture/Compare/PWM (CCP) modules, multiple timers, and nanoWatt Technology dynamic power management modes including Idle, Sleep, and ultra-low-power Timer1 oscillator operation. The 36 I/O count enables direct connection to a wide variety of sensors, displays, and actuators without external glue logic. The PIC18LF4320 architecture uses a 16-bit instruction word with an 8-bit data path, Harvard memory organization, and a hardware multiplier for single-cycle 8x8 operations. The enhanced instruction set includes indirect, indexed, and relative addressing modes for efficient C and assembly code generation. Self-programmability via ICSP (In-Circuit Serial Programming) allows firmware updates in the field, while the 100k endurance cycle rating supports frequent parameter storage in EEPROM emulation schemes. Typical applications include industrial control and sensor interface boards, consumer appliance control panels, low-power remote sensor nodes, HVAC thermostat controllers, building automation peripherals, and USB HID/CDC device controllers when paired with a PIC18F2550-style companion. The wide 2.0-5.5 V operating range also makes it suitable for battery-powered designs using 2xAA cells, lithium chemistries, or regulated 3.3 V rails. When designing with this device, observe Microchip's recommended decoupling (0.1 uF on every VDD/VSS pair plus a bulk 10 uF), keep MCLR either tied to VDD through a 10 kohm resistor or driven by a proper supervisor, and use a 20 MHz or lower crystal if the design requires precise USART baud-rate generation. Industrial-grade parts must operate within -40C to +85C ambient per Microchip datasheet notation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select, source, and integrate the PIC18LF4320T-I/PT efficiently.

PIC18LF4321T-I/PT

PIC18LF4321T-I/PT - 8-bit 40MHz 8KB Flash MCU 44-TQFP | Microchip

The Microchip Technology PIC18LF4321T-I/PT is an 8-bit PIC microcontroller from the PIC18F family, featuring a 40 MHz core, 8 KB (4K x 16) of Flash program memory and 512 bytes of SRAM in a 44-pin TQFP (10x10 mm) package. The 'LF' prefix indicates a low-voltage variant designed to operate from 2.0V to 5.5V, while the 'T' suffix designates tape-and-reel packaging and the 'I' indicates the industrial -40C to +85C temperature range. This combination makes it suitable for cost-sensitive embedded designs that must run from a single Li-ion cell or from a 3.3V regulated rail. A PIC18 microcontroller is a modified Harvard RISC architecture 8-bit MCU built around an enhanced instruction set with 16-bit instructions and an 8-bit data path. PIC18 devices sit within the broader PIC family hierarchy: PIC10/12/16/18 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The PIC18 line specifically targets high-performance applications with up to 40 MHz operation, integrated peripherals such as ADC, PWM, I2C, SPI, UART, and USB (where applicable), and self-programming Flash memory. Compared to baseline PIC16 parts, PIC18 adds linear program memory addressing, a hardware multiplier, and a richer interrupt controller. Key features of the PIC18LF4321 include 8 KB of self-programmable Flash, 256 bytes of EEPROM, 34 digital I/O pins, a 10-bit ADC with multiple channels, two analog comparators, two 8-bit timers plus three 16-bit timers, an enhanced USART, MSSP (I2C/SPI), and the standard PIC18 nanoWatt power-managed feature set. The Flash endurance is rated for a minimum of 10K erase/write cycles and data EEPROM for 100K cycles, supporting frequent in-field firmware updates. The LF family uses Microchip's nanoWatt technology with multiple power-managed operating modes including run, idle, sleep, deep sleep, and RTCC from a low-power oscillator. This architecture reduces quiescent current to microampere levels in sleep, enabling battery-powered designs that wake on interrupts and resume execution within microseconds. Typical applications include industrial sensor interfaces, home appliances and white goods, low-cost motor control, USB peripherals on the PIC18F/LF4321 family, battery-powered metering, and consumer electronics. The 44-pin TQFP footprint and Microchip's free MPLAB X IDE with XC8 compiler create a low-cost entry point for embedded engineers. When designing with this part, verify the core supply voltage and analog reference setup; the LF variant does not include a 5V-only regulator and requires proper decoupling on AVDD/AVSS pins. Engineers upgrading from the PIC18F4321 (F = standard voltage, 4.2V-5.5V) must verify that their firmware operates correctly across the LF's wider 2.0V-5.5V range.

The Microchip Technology PIC18LF4331-I/ML is an 8-bit PIC18F-family flash microcontroller IC running at up to 40 MHz, with 8 KB (4K x 16) of on-chip program Flash, 768 bytes of RAM, and 256 bytes of EEPROM, housed in a 44-pin QFN (8x8 mm) package. The LF (low-voltage F) variant operates across a wide 2.0 V to 5.5 V supply range, supporting both battery-powered and 5 V regulated designs. The 44-QFN package integrates 34 digital I/O lines plus dedicated peripherals such as nanoWatt power management, an enhanced 14-bit high-performance PWM module, a 10-bit A/D converter with up to 9 channels, and Motor Control PWM peripherals suitable for advanced motor control loops. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, I/O peripherals, and interrupt logic on a single die. The PIC18F family belongs to the 8-bit CMOS microcontroller category, itself a branch of microcontrollers (MCUs), which in turn are sub-classes of embedded processors, semiconductors, and integrated circuits (ICPs). The PIC18F family builds on the legacy PIC16 architecture by adding a 16-bit instruction word, linear memory addressing, hardware multiplier, and C-friendly design, making it a common choice for low-power real-time control applications where deterministic behavior is more important than raw MIPS. Key differentiating features include the nanoWatt technology power management suite (multiple idle/sleep modes, ultra-low-power Real-Time Clock calendar, and on-chip Low-Voltage Detect), the 14-bit Enhanced PWM (motor-control-grade PWM with programmable dead-band, fault inputs, and center-aligned modes), and the 9-channel 10-bit ADC. The 44-QFN (8x8) package provides a thermally efficient exposed pad with low RθJA, which improves continuous high-current GPIO drive and PWM switching performance compared with equivalent PDIP or QFP variants of the same die. Typical applications span 3-phase brushless DC (BLDC) motor control, sensor-less fan / pump controllers, advanced ceiling-fan and HVAC blowers, compact white-goods inverter boards, and low-cost industrial sensor transmitters. The combination of dedicated motor-control PWM, fast ADC, and nanoWatt sleep modes also makes it attractive for energy harvesting and solar-powered remote nodes that spend most of their life in sleep state. When designing with this part, follow the Microchip PIC18F4331/4331/4431 datasheet guidelines for the QFN exposed pad - it must be soldered to a sufficiently large copper pour to meet the thermal and electrical ground bond requirements. In-system programming is via ICSP on RB6/RB7, so the PCB must keep those pins accessible. Always check the errata and DS39591 family reference manual for the specific silicon revision in your lot before locking the BOM.

The Microchip Technology PIC18LF4331T-I/PT is a low-power 8-bit PIC18 microcontroller running up to 40 MHz, integrating 8 KB of FLASH program memory (organized as 4K x 16 words) and 768 bytes of SRAM in a 44-pin TQFP (10x10 mm) package. It belongs to the PIC18F4331/4431 motor-control family and is tailored for digital signal control of brushless DC, switched-reluctance, and AC-induction motors via its integrated 14-bit-resolution Power Control PWM module. What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that processes data in 8-bit-wide chunks, integrates CPU core, program memory (FLASH/ROM), data memory (RAM), and a rich peripheral set including timers, ADC, PWM, and communication interfaces. Positioned in the taxonomy: 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor device. The PIC18 family uses an enhanced Harvard RISC architecture with 16-bit instructions and 8-bit data paths, balancing deterministic real-time control with low power consumption for cost-sensitive industrial and consumer applications. The 'LF' designation indicates an extended-voltage variant operating down to 2.0V, making the part suitable for battery-powered designs across the industrial -40C to +85C range. The 'T' suffix marks Tape-and-Reel packaging for high-volume SMT assembly, while 'I/PT' confirms the industrial temperature grade and TQFP-44 pinout. The integrated 10-bit ADC (up to 9 channels), two CCP/ECCP modules, two analog comparators, and the dedicated Motion Feedback Module (10-bit Slope ADC) eliminate the need for external motor-control ICs in many single-axis BLDC designs. Typical applications span sensorless BLDC fan and pump controllers, permanent-magnet synchronous motor (PMSM) drivers for HVAC blowers, small appliance motor control (vacuum cleaners, washing-machine pumps), and stepper/switched-reluctance drives in industrial automation. Communication peripherals include I2C, SPI, and an enhanced USART with autobaud detection, easing integration with sensors and HMI modules. When designing with this MCU, verify that the application's code footprint does not exceed the 8 KB FLASH limit; the PIC18K-series (e.g., PIC18F26K22) is the recommended migration path if software growth requires more headroom. Always read-latch-protect configuration bits and use the ICD3 or PICkit 4 programmer for in-circuit debug access.

PIC18LF43K22-E/MV - 8KB Flash 8-bit nanoWatt XLP MCU | Microchip
PIC18LF43K22-E/MV

PIC18LF43K22-E/MV - 8KB Flash 8-bit nanoWatt XLP MCU | Microchip

The Microchip Technology PIC18LF43K22-E/MV is an 8-bit RISC microcontroller from the PIC18 (LF) XLP family, integrating 8 KB of Flash program memory, 512 bytes of RAM and 256 bytes of EEPROM in a 40-pin UQFN (5x5 mm) package with exposed pad. It executes a single instruction per clock cycle at up to 64 MHz, delivering roughly 16 MIPS while drawing only nanoWatt-class sleep currents, making it a fit for line- and battery-powered edge nodes. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile Flash program memory, RAM, EEPROM/Flash data, configurable digital peripherals (timers, I/O, communication ports) and analog peripherals (ADC, comparators, DAC) on one die. PIC18 microcontrollers use an enhanced RISC Harvard architecture that maps program and data memory onto separate buses, which lets the fetch and execute stages overlap. Within the PIC taxonomy (PIC10/12/14/16/17/18/24/32-bit families), the PIC18 sits at the top of the 8-bit line, offering the largest program space and the richest peripheral set; the PIC18F (Flash) subfamily is the mainstream 5V node, while the PIC18LF (Low-Voltage F) variant covers 1.8V-3.6V operation for battery-backed designs. Both Flash families descend from Microchip's broader hierarchy: microcontroller -> embedded computing -> semiconductor -> integrated circuit. Key features of the PIC18LF43K22-E/MV include ten 10-bit ADC channels, two 8-bit timers plus three 16-bit timers, two analog comparators, a hardware EUSART, two MSSP (I2C/SPI) modules, an mTouch capacitive-sensing peripheral and a wide 1.8V-3.3V operating range. nanoWatt XLP technology drops standby current to roughly 20 nA in real-time-clock mode and below 100 nA in sleep, preserving battery life on multi-year deployments. The part combines an enhanced mid-range 8-bit RISC core, dual oscillator/PLL clocking, an HFINTOSC that removes the external crystal in many designs, and on-chip debug via ICD over PGED/PGEC. The 40-pin UQFN (MV package, 5x5x0.5 mm) lands the device on a footprint that competes with much newer ARM Cortex-M0+ chips but retains the PIC18 instruction set, easing migration for established PIC code bases and shortening the path through CE/FCC for legacy products. Typical applications include battery-powered sensor pods, low-energy IoT edge nodes, consumer white-goods HMI controls, instrumentation front-ends, and industrial telemetry where a 1.8V supply rail is available. The dual-I2C/SPI chain plus 10-bit ADC simplifies temperature, pressure and level sensing with minimal external components. When designing with this MCU, budget for the exposed thermal pad to be soldered to a 1 cm² copper pour so that the 64 MHz core remains within the -40 °C to +125 °C (E = Extended) junction envelope. Always place the standard 100 nF decoupling cap within 5 mm of every VDD/VSS pair and add a 10 µF bulk capacitor near the IC to suppress analog rail noise.

PIC18LF43K22-E/P

PIC18LF43K22-E/P - 8-bit PIC MCU, 8KB Flash, 40-Pin DIP | Microchip

The Microchip Technology PIC18LF43K22-E/P is an 8-bit PIC18 microcontroller featuring 8KB of Flash program memory, 3968 bytes of SRAM, and 256 bytes of EEPROM, packaged in a 40-pin PDIP (DIP-40). The LF prefix denotes the low-power (1.8V–3.6V) core variant of the PIC18(L)F2X/4XK22 family, which targets battery-friendly and energy-harvesting designs. The -E suffix indicates the extended operating temperature grade of -40°C to +125°C, while /P denotes the through-hole PDIP-40 package. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and peripherals such as timers, ADC, communication interfaces, and I/O ports. The PIC18 family occupies Microchip's mid-range 8-bit portfolio, sitting between the baseline PIC10/12/16 families and the 16-bit dsPIC/DSC line. PIC18 MCUs use a modified Harvard architecture with a RISC instruction set, 16-bit instructions, and an 8-bit data path, and they are programmed via Microchip's MPLAB X IDE with XC8 compilers. PIC18 parts are widely used in industrial automation, consumer appliances, sensor hubs, and automotive body modules where deterministic 8-bit performance and low power matter more than raw compute throughput. Key features of the PIC18LF43K22 include eXtreme Low Power (XLP) technology with nanoWatt XLP sleep currents below 50 nA typical, a 10-bit ADC with up to 28 channels, multiple Enhanced USART, MSSP (SPI/I2C), and CCP/ECCP modules, a 16-bit timer/counter, and a wide 1.8V–3.6V operating range that makes the part directly suitable for single-cell Li-ion or two-AA-battery systems. Internal 32 kHz and 16 MHz oscillators plus PLL support a top instruction rate of 16 MIPS at 64 MHz CPU clock, while on-chip mTouch capacitive sensing hardware enables touch-button user interfaces without external components. The PIC18 architecture combines a deterministic RISC pipeline with a rich peripheral set, giving the LF43K22 deterministic interrupt latency for real-time control loops. Compared to ARM Cortex-M0 alternatives, PIC18 parts typically consume less sleep current but offer lower MIPS; compared to older PIC16 parts, PIC18 adds linear memory, hardware multiplier, and 16-bit instruction word for higher code density. The 40-pin PDIP package remains the development platform of choice for breadboard prototyping and legacy designs that must remain through-hole for serviceability or conformal coating reasons. Typical applications include industrial sensor transmitters, battery-powered remote controls, low-power wireless sensor nodes, building automation nodes (thermostats, HVAC actuators), handheld test instruments, and automotive body controllers (lighting, mirror, seat modules) using the AEC-Q100-qualified PIC18F version. The XLP sleep modes also make the LF43K22 a strong choice for energy-harvesting designs where the MCU spends most of its life in deep sleep. Designers should budget decoupling capacitance (typically 100 nF plus 10 µF bulk) close to VDD/VSS pins, route MCLR through a 10 kΩ pull-up, and follow Microchip's emulator/ICSP pinout rules if in-circuit programming is required. PIC18 code compiled with XC8 v2.x differs from older HI-TECH and MPLAB C18 binaries in calling convention, so legacy source code may need porting. This page synthesizes distributor pricing, drop-in PIC18 family alternatives in the same PDIP-40 footprint, and practical design notes that are not consolidated in the manufacturer datasheet, giving procurement and firmware teams a faster path to a second source or drop-in replacement.

The "LF" low-power process technology provides reduced active and sleep current versus the standard "F" siblings, which is the principal differentiator from PIC18F442 in 5 V designs. Code compatibility across PIC16C5X/PIC12CXXX/PIC16CXX/PIC17CXX preserves legacy code while enabling migration to higher performance. Typical applications include industrial automation controllers, sensor interface nodes, automotive body electronics (non-safety), HVAC control panels, smart metering, and consumer appliance control. The 44-PLCC footprint is convenient for socketed prototyping and field-replaceable modules, and the 5.5 V tolerance eases integration with legacy 5 V analog front ends. When designing with this part, place decoupling capacitors (100 nF plus bulk) within a few millimetres of every VDD/VSS pin pair, especially because the ADC reference shares VDD. Configure CONFIG words to match oscillator mode, BOR threshold, and watchdog state before code execution - locked-out debug or wrong clock mode is the most common bring-up failure on this family. This page consolidates distributor pricing, drop-in compatible alternatives, and practical design notes that go beyond the manufacturer datasheet to support faster design-in and sourcing decisions for the PIC18LF442-I/L.

The "LF" variant operates across 2.0 V to 5.5 V, making it ideal for low-voltage designs that must share rails with 3.3 V peripherals and 5 V analog blocks. The "I" temperature suffix indicates an industrial temperature range of -40 C to +85 C, while the "/ML" suffix designates the lead-free 8x8 mm QFN with exposed pad. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (flash), volatile working memory (RAM), and a rich set of on-chip peripherals. Within the embedded hierarchy, an 8-bit MCU like the PIC18F sits below 32-bit Cortex-M parts in arithmetic performance but above discrete logic in functional integration. The PIC18LF4420 belongs to the PIC18F "high-performance 8-bit" family that adds a hardware multiplier, C-friendly architecture, and 16-bit instructions compared to baseline PIC16F parts. Key features of the PIC18LF4420 include a 10-bit ADC with up to 13 input channels, a 4x4 hardware multiplier for fast DSP-style math, two enhanced CCP modules and one USART, I2C, SPI, and a parallel slave port for external memory expansion. The device supports self-programming under firmware control, allowing bootloader-driven field updates and on-chip EEPROM emulation. An extended watchdog timer and brown-out reset help recover from code faults and brown-out events. Architecturally, the PIC18LF4420 uses a 16-bit instruction word with an 8-bit data path, a modified Harvard memory map, and a priority-level interrupt controller. The 40 MHz oscillator provides up to 10 MIPS, and the nanoWatt technology reduces sleep current to under 100 nA with the RTCC and watchdog running, which is critical for battery-powered sensors. Typical applications include industrial sensing and control, USB/HID bridges when paired with a serial interface, low-power sensor hubs, motor control loops, and white-goods user interfaces. The wide voltage range and generous peripheral set make it a popular choice for migration from older PIC16F and PIC18F designs. Drop-in compatibility with PIC18F4520 in the same 44-pin QFN lets engineers move between 5 V F-variant and LF-variant designs without PCB rework.
