PIC18LF242-I/SP

PIC18LF242-I/SP - 8-Bit 40MHz PIC18 MCU 16KB Flash 28-SPDIP | Microchip

The Microchip PIC18LF242-I/SP is an 8-bit CMOS FLASH-based PIC microcontroller delivering 10 MIPS (40 MHz) performance with 16 KB (8K x 16) of on-chip program memory, packaged in a 28-pin SPDIP (Skinny Plastic DIP) through-hole footprint. Operating from 2.0 V to 5.5 V, the LF variant is optimized for low-voltage and battery-backed designs where the standard PIC18F242 would not tolerate rail droop. The part integrates 768 bytes of RAM, 256 bytes of EEPROM, 23 digital I/O pins, and the PIC18 instruction set with 16-bit-wide opcodes that improve code density over PIC16 cores. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU, program memory (FLASH or ROM), data memory (RAM), EEPROM, peripherals, and interrupt logic on one die. The PIC18 family sits in Microchip's mid-range 8-bit hierarchy: PIC10/12/16/18 -> 8-bit MCU -> microcontroller -> embedded controller. PIC18 parts add a linear program-memory map, hardware multiplier, C-friendly architecture, and prioritized interrupts that the smaller PIC16 cores lack, making them the workhorse for cost-sensitive 8-bit designs that need real peripherals like CAN, USB, or Enhanced USART. Key features include a 10-bit ADC (5 channels on this 28-pin part), 1 capture/compare/PWM module, 1 Enhanced USART, MSSP for SPI/I2C, two 8-bit timers plus three 16-bit timers, and a programmable Watchdog Timer with its own on-chip RC oscillator. The FLASH program memory is in-circuit serial programmable through ICSP, and the device supports ICD2/ICD3 real-time in-circuit debugging with two I/O pins dedicated to that purpose. With four oscillator modes including a 31 kHz LP mode and an 8x software PLL, the LF242 is tailored for low-power and crystal-stabilized timing. The PIC18LF242-I/SP is fabricated on Microchip's CMOS FLASH process with low-power enhancements versus the PIC18F242, including extended supply range down to 2.0 V (PIC18F242 bottom is 4.2 V). This makes the LF part the correct choice when the rail is sourced from a Li-ion cell, a 3.3 V LDO, or a regulated 2.5 V analog domain, while the F part is the more cost-effective pick for 5 V-only industrial boards. Typical applications include industrial control panels, low-power instrumentation, sensor signal conditioning, motor control front-ends, and battery-backed security or HVAC peripherals. In each case the PIC18LF242 supplies 5-V-style peripherals from a 3.3 V rail while leaving enough MIPS for state-machine glue logic and a simple RTOS loop. When designing with this device, ensure the supply decoupling follows Microchip's PIC18 LF family reference: one 100 nF ceramic at VDD and one bulk (>=10 uF tantalum or 47 uF aluminum) at the board's power entry. Reserve pins RB6 and RB7 for ICSP clock/data; adding series resistors or a buffer on these pins will block in-circuit programming and debugging.

The Microchip Technology PIC18LF2420-I/SO is an 8-bit RISC PIC18-family microcontroller running up to 40 MHz, integrating 16 KB (8K x 16) of Flash program memory, 768 bytes of SRAM and 256 bytes of EEPROM data memory in a 28-pin SOIC package. The LF variant is the low-power, wide-voltage node of the PIC18F2420 family, operating from 2.0 V to 5.5 V with Microchip's nanoWatt technology for dynamic power management. The 28-SOIC footprint delivers 25 digital I/O pins, 10-bit multi-channel ADC, two analog comparators, two USART modules, one MSSP (SPI/I2C), two capture/compare/PWM modules and a 16-bit timer architecture. What is a PIC18 microcontroller? PIC18 is Microchip's enhanced 8-bit RISC core family, evolving the baseline PIC16 architecture with a 16-bit instruction word, linear memory addressing, hardware multiplier, prioritized interrupts and C-friendly compiler support. As 8-bit MCUs, PIC18 parts sit in the broader taxonomy of microcontroller -> embedded controller -> semiconductor device, and the LF sub-family specifically targets battery-friendly designs through nanoWatt power-saving modes. The architecture's deterministic single-cycle instruction execution makes PIC18 well-suited for real-time control loops where predictable latency matters more than raw throughput. Key differentiating features of the PIC18LF2420-I/SO include the 2.0 V to 5.5 V operating range with full peripheral operation across the band, 10-bit ADC with up to 13 input channels sharing package pins, internal oscillator options selectable via configuration fuses, and nanoWatt idle/sleep modes that drop core current to the microampere range. The 28-SOIC industrial-temperature grade (-40C to +85C, denoted by the I suffix) supports harsh-environment designs while the LF voltage range allows direct battery connection (two AA cells) without a boost converter. Technical depth: the silicon uses CMOS Flash technology with self-programmability in the application circuit, eliminating external boot memory. The enhanced 16-bit instruction set supports direct, indirect, relative and indexed addressing, plus a hardware 8x8 multiplier cycle that accelerates 16-bit arithmetic. Three external interrupt sources and a configurable interrupt controller service the timer, capture/compare, ADC, USART and MSSP peripherals. Typical applications include industrial sensor conditioning, automotive body controllers, building automation nodes, low-power remote controls, consumer appliance user interfaces and battery-backed instrumentation. The 40 MHz throughput with 16 MIPS sustained performance, combined with deep sleep and RTCC wake-up, makes it a strong fit for mains-battery hybrid designs. A key design consideration: the LF silicon requires the LF configuration bits set correctly; substituting with the non-LF (F-only) variant in the same socket is electrically compatible at 4.5 V to 5.5 V but not below 4.2 V, so always verify the brown-out and voltage-rail spec when designing for two-cell alkaline supplies. Decouple VDD/VSS with 100 nF ceramic placed within 5 mm of the pins to suppress switching transients from the internal charge pump. This page synthesizes verified distributor pricing, drop-in PIC18-family alternatives and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference for sourcing, second-sourcing and design-in of the PIC18LF2420-I/SO.

PIC18LF2431-I/SO

PIC18LF2431-I/SO - 8-Bit 40MHz 16KB Flash MCU | Microchip

The Microchip PIC18LF2431-I/SO is an 8-bit CMOS flash-based microcontroller from the PIC18 family, operating at up to 40 MHz (10 MIPS) and integrating 16 KB of program Flash, 768 bytes of RAM, and 256 bytes of EEPROM in a 28-pin SOIC package. The 'LF' prefix denotes the low-voltage variant that operates across 2.0V to 5.5V, making it well suited to battery-powered designs where the standard PIC18F2431 (4.2V-5.5V) cannot reach. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU, RAM, non-volatile program memory, peripherals, and I/O on one die. 8-bit MCUs sit at the entry level of the microcontroller taxonomy - between fixed-function logic ICs and 32-bit Cortex-M microcontrollers - and remain dominant in cost-sensitive, deterministic control applications such as motor control, sensor interfaces, and appliance electronics. The PIC18 family in particular is known for its 77 single-word instruction set, 16-bit instructions, and on-chip peripherals like the enhanced Capture/Compare/PWM (ECCP) module that this part uses for power-conversion and motor-control loops.

The 'LF' low-voltage silicon supports an extended VDD range down to 2.0V; this is the principal parametric difference from the PIC18F2431, which requires 4.2V minimum. Both parts share the same 28-SOIC pinout, allowing a one-line BOM swap when a design needs to migrate between the two voltage windows. Typical applications include sensorless BLDC motor control (the integrated 14-bit PWM is purpose-built for this), switch-mode power supply (SMPS) digital control loops, industrial fan/pump controllers, and battery-powered sensor signal-conditioning front-ends. Industrial-grade (-40C to +85C) operation is preserved through the 'I' suffix in the part number. Designers should note that the 28-SOIC variant is the right choice when 22 I/O pins suffice; the PIC18LF2431 family is also available in 40-pin PDIP and 44-pin TQFP packages if more I/O are needed. The nanoWatt modes (Idle, Sleep, and Timer1/RTCC oscillator) reduce quiescent current below 1 uA in typical Sleep conditions, which is the primary lever for extending battery life in portable designs.

The Microchip Technology PIC18LF2439-I/SP is an 8-bit PIC18 microcontroller built around a RISC architecture running at up to 40 MHz, integrated with 12 KB of Flash program memory (6K x 16 words), 640 bytes of SRAM, and 256 bytes of EEPROM, all housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The part operates across 2.0 V to 5.5 V supply rails with the LF (low-voltage/F-series) silicon, supporting 2.5 V / 3.3 V / 5 V designs and exposing up to 21 general-purpose I/O pins, including motor-control peripherals such as a power-control PWM module and a 14-bit-resolution motion-feedback channel typical of the PIC18F2439/4439 family. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, data EEPROM, and peripheral IP such as timers, capture/compare/PWM channels, ADC, and communication controllers. PIC18F-family MCUs sit in the middle of Microchip's 8-bit hierarchy - above PIC10/PIC12/PIC16 baseline parts in code density and peripheral richness, below the PIC24/dsPIC and PIC32 16-/32-bit families in raw performance. They target cost-sensitive, deterministic, low-power embedded designs where an 8-bit instruction set and Harvard bus keep firmware development simple and toolchain license fees at zero. Key features of the PIC18LF2439-I/SP include 8 MIPS peak throughput at 40 MHz, 10-bit ADC, three timer modules, two capture/compare/PWM modules optimized for switched-mode and motor control, an Enhanced USART, an I2C/SPI master/slave port, and a 10-bit PWM with complementary outputs for driving half-bridges. Hardware math acceleration (8x8 hardware multiply in one cycle) and a vectored interrupt controller with 17 sources reduce firmware complexity for closed-loop applications such as brushless DC (BLDC) and switched-reluctance motor (SRM) drives. The PIC18LF2439 uses a 16-bit instruction word with a 32 KB linear code space - of which 12 KB is implemented in this die - and a 16-level hardware stack with software-pushable return addresses. The Harvard bus architecture decouples program fetch from data access, and the 8-bit data path keeps arithmetic unit area and power dissipation minimal. The "LF" prefix denotes the wide-range F-variant silicon (2.0-5.5 V), distinguishing it from non-LF members that require 4.2-5.5 V. Typical applications for the PIC18LF2439-I/SP include 3-phase BLDC motor commutation, sensorless BLDC pumps and fans, switched-reluctance drives, low-end servo control, and ceiling-fan / appliance variable-frequency drives. The 28-SPDIP package suits through-hole manufacturing, hobbyist prototypes, and harsh-environment industrial boards where leaded parts survive thermal and vibration stress better than leadless QFN packages. The PIC18F2439/4439 family is one of Microchip's classic 8-bit motor-control families; engineers who design firmware on this die typically use the MPLAB XC8 toolchain, MPLAB Code Configurator (MCC), and the application note AN1079 (sensorless BLDC with back-EMF). When designing with this part, take care to respect the absolute maximum VDD of 7.0 V and to clamp motor back-EMF events that can ride on the supply rail. Brown-out-reset (BOR) and the configurable low-voltage-detect (LVD) thresholds must be enabled during the configuration-word programming step - leaving BOR disabled can result in corrupted EEPROM during supply dips. Always program the CONFIG registers with the values from the latest Microchip datasheet before loading application firmware.

As the LF variant of the PIC18F2439, it is designed for low-voltage operation while preserving the PIC18 enhanced instruction set and the integrated motor-control PWM peripherals that distinguish the PIC18F2439 sub-family. An 8-bit microcontroller is a single-chip computer whose ALU, registers, and data bus are 8 bits wide, executing one byte per instruction cycle. Within the broader semiconductor taxonomy it belongs to the microcontroller class (MCU), which itself sits under microcontrollers and processors (MPU) and ultimately under digital semiconductors. The PIC18F family specifically targets applications requiring deterministic real-time control, mid-range code density, and rich on-chip peripherals, occupying the middle ground between baseline PIC10/12/16 parts and the 16-bit dsPIC/PIC24 families. Key features of the PIC18LF2439T-I/SO include a 40 MHz maximum oscillator (10 MIPS instruction throughput), 21 digital I/O pins, 8-channel 10-bit ADC, two USART modules, and dedicated motor-control PWM with complementary outputs and programmable dead time. The LF suffix indicates a wide VDD operating range typically spanning 2.0 V to 5.5 V, making it suitable for battery-powered motor control. Tape-and-reel ('T') packaging supports high-volume SMT assembly, and the industrial '-I' temperature grade covers -40 C to +85 C operation. The architecture combines a 16-bit instruction word with an 8-bit data path and a hardware multiply, giving C-compiler efficiency close to 16-bit parts. The integrated motor-control PWM module (six channels with complementary outputs and dead-band control) eliminates the need for an external PWM controller, while the 10-bit ADC with up to 8 input channels enables closed-loop current and voltage sensing. Typical applications include BLDC and PMSM motor drives, sensored or sensorless fan and pump controllers, small appliance inverters, HVAC damper and valve actuators, and low-voltage DC motor control boards. Its wide VDD range also supports USB-free tethered designs and 3.3 V system rails. When designing with this MCU, allocate the analog and digital supply pins (AVDD/AVSS) correctly and bypass them with 100 nF capacitors placed within 3 mm of the pins. Configure the motor-control PWM dead-time registers in firmware rather than relying on hardware defaults to prevent shoot-through in the inverter stage.

The 28-QFN package reduces PCB footprint by approximately 60% versus a 28-SOIC footprint while exposing a thermal pad that lowers theta-JA and improves high-current I/O performance. Architecturally, the part uses a Harvard cache architecture with separate program and data buses, a 32-level hardware stack, and an 8x8 hardware multiply that accelerates 16-bit math in a single cycle. The integrated USB SIE handles NRZI encoding, bit stuffing, and CRC5/CRC16 in hardware, eliminating external PHY chips for low-speed and full-speed USB. Typical applications include USB HID peripherals (keyboards, mice, gamepads), USB-to-UART bridges, low-voltage sensor nodes, industrial data loggers, and consumer electronics that need a low-pin-count USB device interface. The LF voltage range (2.0-5.5V) makes the part a strong fit for single-cell Li-ion powered devices as well as 3.3V and 5V industrial buses. Design consideration: the QFN package requires a via-array thermal pad soldered to a copper pour for the datasheet-specified thermal performance. Programming/debug is supported natively by Microchip's MPLAB X IDE, MPLAB XC8 compiler, and PICkit or ICD tools.

It integrates 24KB of Flash program memory, 2KB of SRAM, and 256 bytes of EEPROM, with a 12-bit A/D converter and a full-speed USB 2.0 peripheral (12 Mbit/s). A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, plus peripherals such as timers, communication interfaces, and analog converters. Within the broader taxonomy, the PIC18LF2458 is an 8-bit CISC Harvard-architecture MCU in the PIC18 family of microcontrollers, which itself sits inside Microchip's 8-bit PIC microcontroller portfolio and the wider semiconductor MCU category. It executes most instructions in one instruction cycle, providing 48 MHz / 4 = 12 MIPS performance at maximum clock, and provides three serial ports (FS-USB, I2C, and SPI up to 10 Mbit/s). Key differentiating features of the PIC18LF2458 include: nanoWatt technology for power-managed sleep modes, a 12-bit A/D converter (versus the 10-bit A/D found on many earlier PIC18F2x/4x parts), 24 digital I/O pins across 28 pins, an internal 31 kHz to 8 MHz oscillator with PLL for 48 MHz operation, and a full-speed USB transceiver on-chip. The combination of integrated USB 2.0, ample memory, and 12-bit ADC in a small SOIC-28 footprint differentiates the LF2458 from simpler 8-bit MCUs that require an external transceiver or ADC. Technically, the LF2458 uses a 16-bit instruction word Flash architecture with separate program and data buses (Harvard), enabling simultaneous access to instruction and data memory. The CPU features an 8 x 8 hardware multiplier and a barrel shifter, supporting single-cycle multiply operations. Power management offers several low-power modes (Idle, Sleep, and PRI_RUN variants of nanoWatt), with the LF variant extending the operating voltage window down to 2.0V for direct Li-ion coin-cell compatibility. Typical applications include low-speed USB peripherals (HID, CDC, custom HID-class devices), 12-bit sensor data-acquisition front ends, low-power industrial controllers, and battery-powered instruments that need USB connectivity only when tethered to a host. In each, the on-chip USB transceiver eliminates the external transceiver and 5V regulator typically required by discrete designs. In a battery-powered design, the low-voltage LF range enables direct operation from two alkaline or NiMH cells; in a USB CDC bridge, the LF2458 appears as a virtual COM port without external crystals beyond the standard 20 MHz resonator with PLL. When designing with the PIC18LF2458, pay attention to the ICD/ICSP header pinout to ensure MCLR, PGC, and PGD are brought out for in-circuit programming. Use a 20 MHz or 24 MHz crystal/resonator with the PLL enabled to derive the 48 MHz system clock required by the USB module. Decouple VDD/VSS with 100 nF + 1 uF near each pair, and keep the D+/D- traces matched and short per the USB 2.0 spec. For lowest sleep current, disable unused peripherals before entering Sleep.

The Microchip Technology PIC18LF248-I/SP is a low-power 8-bit RISC microcontroller with integrated CAN module, delivering 16KB of Flash program memory and 768 bytes of RAM in a 28-pin SPDIP through-hole package. Operating at 40 MHz instruction clock (10 MIPS), it supports a wide 2.0V to 5.5V VDD range through its LF (low-voltage/F) process variant, providing supply flexibility for both 3.3V and 5V system designs. The integrated CAN 2.0B active peripheral makes it a drop-in controller for distributed industrial networks and automotive body ECUs. A microcontroller (MCU) is a single-chip programmable computer integrating a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a set of on-chip peripherals such as timers, ADC, communication interfaces, and I/O. The PIC18 family uses Microchip's enhanced Harvard RISC architecture with a 16-bit instruction word and 8-bit data path, giving one instruction per clock and deterministic interrupt latency. The 'LF' prefix designates the low-voltage F-process variant, which extends the operating voltage down to 2.0V, while the 'F' variant (e.g., PIC18F248) requires 4.2V minimum. The '-I' suffix denotes the industrial operating-temperature grade -40°C to +85°C, and '/SP' specifies the 28-pin Skinny Plastic DIP (SPDIP) through-hole package. The PIC18LF248 includes 23 digital I/O pins, a 10-bit 5-channel ADC, two 8-bit and three 16-bit timers, an Enhanced USART, an MSSP (SPI/I2C) module, and the headline feature: a hardware CAN 2.0B peripheral with bit rates up to 1 Mbps. The integrated CAN controller removes the external MCP2515 that designers would otherwise need, saving BOM cost and board area in Node and Cluster designs. The 256-byte EEPROM supports non-volatile user settings without external storage. Typical applications include industrial CAN node terminals (DeviceNet/CANopen slaves), building automation controllers, automotive body and HVAC modules running at 12V, sensor-interface boards with CAN reporting, and low-cost legacy-system retrofits. Industrial networks built on CANopen or DeviceNet often specify the PIC18F248/LF248 family because the silicon is qualified for 8 MHz oscillator operation with CAN bit rates to 1 Mbit/s, and the firmware toolchain (MPLAB X + XC8 + MCC) is mature and free. When designing in this part, take care that the LF variant's max VDD (5.5V) is identical to the F variant, but the minimum is 2.0V rather than 4.2V - if your application requires 5V-only operation, the PIC18F248 is interchangeable. The integrated CAN module requires an external 3.3V or 5V CAN transceiver (e.g., MCP2551 or MCP2562) to drive the physical bus; the MCU handles only the digital protocol layer. This page synthesizes distributor pricing, drop-in alternatives from the same PIC18 family, and practical CAN-application design notes that go beyond the bare datasheet to give engineers a real procurement and design start.

PIC18LF2480T-I/ML

PIC18LF2480T-I/ML - 40MHz 8-Bit MCU, 16KB Flash, ECAN, 28-QFN | Microchip

The Microchip Technology PIC18LF2480T-I/ML is an 8-bit PIC18 microcontroller delivering up to 40 MIPS of CPU performance from an enhanced RISC architecture, integrating 16 KB of Flash program memory, 768 bytes of SRAM, and 256 bytes of EEPROM in a 28-pin QFN (6x6 mm) package with an exposed thermal pad. The LF prefix designates the low-voltage (2.0 V to 5.5 V VDD) variant of the PIC18F2480 family, targeting battery-powered and energy-harvesting designs where the standard F part (4.2 V to 5.5 V) cannot operate. Onboard peripherals include a 10-bit ADC with up to 8 channels, an ECAN (Enhanced Controller Area Network) module, multiple timers, USART, MSSP (SPI/I2C), and nanoWatt Technology power management for sleep currents down to the nanoampere range. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (SRAM), and configurable peripherals. Within the taxonomy of semiconductors, an MCU falls under digital logic ICs -> microcontrollers -> 8-bit microcontrollers -> PIC18 family (Microchip). The PIC18 family specifically uses a 16-bit wide instruction set with an 8-bit data path, and is widely adopted in industrial control, automotive body electronics, and CAN-bus embedded designs. Key features of the PIC18LF2480T-I/ML include 25 digital I/O pins with individual direction and weak pull-up control, an enhanced CAN (ECAN) module that supports CAN 2.0B active with three transmit buffers and two receive buffers, and nanoWatt Technology that provides multiple idle/sleep modes (Idle, Sleep, and RTCC alarm wake-up) for ultra-low standby current. The instruction set is C-optimized, allowing efficient compilation from Microchip's XC8 toolchain, and the device supports in-circuit serial programming (ICSP) plus background debug via the ICD headers. The 28-QFN (6x6) package with exposed thermal pad (EP) gives the LF2480 a small PCB footprint while still offering good thermal dissipation for sustained 40 MHz operation across the -40C to +85C industrial temperature range. The QFN EP must be soldered to the ground plane on the PCB for both thermal and electrical performance. Typical applications include CAN-bus node controllers in automotive body and chassis ECUs, industrial sensor nodes using the 10-bit ADC, low-voltage handheld instrumentation (2x AA battery-powered), CAN-to-UART gateways, and sensor-actuator nodes on factory automation networks. Compared with the PIC18F2480 (standard F variant), the LF variant extends operation down to 2.0 V and adds nanoWatt Technology, making it the better choice for battery-powered and energy-efficient designs. When designing with this MCU, note that the 28-QFN EP must be soldered to a grounded copper pad for thermal and electrical performance; omitting this connection can raise die temperature under sustained 40 MHz operation and may cause erratic ADC readings due to ground bounce. The LF variant is specified for 2.0 V to 5.5 V operation; the standard F variant requires 4.2 V to 5.5 V.

Architecturally, the PIC18LF2480 uses Microchip's Harvard-based 8-bit RISC core with a 16-bit instruction word and hardware multiplier. The ECAN engine supports CAN 2.0B active with multiple transmit/receive buffers, filters and masks. The 10-bit ADC uses a dedicated successive-approximation converter with selectable acquisition time, supporting mixed-signal applications such as sensor conditioning and motor control feedback. Typical applications include CAN nodes for automotive body and chassis modules, industrial field-bus sensor and actuator interfaces, low-power battery sensor transmitters, HVAC controllers, and appliance control boards. The wide 2.0-5.5 V operating range simplifies designs that must migrate between 3.3 V and 5 V rails without re-firmware. When designing with this part, reserve adequate decoupling on VDD/AVDD pairs, route the 40 MHz oscillator traces short and symmetrical, and follow the ECAN bus-layout guideline (twisted pair, 120 ohm termination at both ends). A dedicated bootloader or ICSP header is recommended for field firmware updates. This page synthesizes distributor pricing, drop-in 28-SOIC alternatives, and practical design notes for the PIC18LF2480T-I/SO not consolidated on the manufacturer datasheet.
