PIC18LF2458-I/SO

PIC18LF2458-I/SO - 24KB Flash USB MCU 8-bit 48MHz

The Microchip Technology PIC18LF2458-I/SO is an 8-bit PIC microcontroller from the PIC18F2458/2553/4458/4553 family, supplied in a 28-pin SOIC (SO) package with industrial -40C to +85C temperature range. The LF prefix denotes a low-voltage variant operating from 2.0V to 5.5V (versus the standard F variant at 4.2V-5.5V), making the LF2458 suited to battery-powered and USB bus-powered designs. 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 device is fabricated on an enhanced FLASH process with nanoWatt XLP deep-sleep modes that draw under 1 µA, making it attractive for battery-powered USB peripherals, HID-class devices, and always-on industrial sensors. Its wide 2.0-5.5 V VDD range and on-chip USB transceiver eliminate the external USB PHY typically required by competing 8-bit MCUs. Typical applications include USB-to-UART bridges, USB Human Interface Devices (keyboard, mouse, gamepad), low-speed data loggers, capacitive-touch front panels, industrial sensor transmitters with USB diagnostics, and educational platforms where the PIC18 USB stack is supported by Microchip's free MLA framework. When laying out the PCB, keep the 28-SOIC VDD/VSS pair short and place a 100 nF decoupling cap within 3 mm of each supply pin. The USB D+/D- traces should be 90 Ω differential and length-matched, with the VBUS sense line routed to a 5V-tolerant I/O.

PIC18LF248-I/SP

PIC18LF248-I/SP - 8-bit MCU, 16KB Flash, 40MHz, CAN, 28-SPDIP

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.

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.

An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, typically used in cost-sensitive, deterministic real-time embedded applications. Within the broader taxonomy, an MCU belongs to microcontrollers -> microcomputers -> embedded processors -> semiconductors. The PIC18 family is Microchip's mid-range 8-bit line, succeeding the PIC16 and adding an enhanced instruction set, linear (un-paged) program memory, and richer peripherals while remaining compatible with legacy designs. The PIC18LF24J10 architecture pairs a Harvard-style RISC core with on-chip Flash and a 16-bit instruction word (16-bit Flash / 8-bit data RAM). Internal oscillator options, an 8x8 hardware multiplier, and self-programmability support field updates. The LF family is optimized for low-voltage operation and is pin-compatible with the F-family PIC18F24J10, enabling a smooth upgrade path to higher speed at 5V when needed. Typical applications include low-power sensor nodes, USB HID bridges (when paired with a USB transceiver), small appliances and home automation, industrial control and instrumentation, and LIN-enabled automotive body modules. Designers frequently choose this part when deterministic 8-bit control, robust peripherals, and Microchip's MPLAB X toolchain support are required at low BOM cost. When designing with the PIC18LF24J10-I/ML, ensure VDD decoupling uses 100nF plus bulk capacitance near the EP pad, respect the 2.0V-3.6V supply range, and use Microchip's ICD 3 / ICD 4 / PICkit 4 in-circuit debuggers for development. Trade-off: the LF family trades maximum frequency for lower voltage flexibility versus the F-family.

PIC18LF24J10-I/SO - 8-Bit 40MHz 16KB Flash MCU | Microchip

The Microchip Technology PIC18LF24J10-I/SO is an 8-bit PIC18J RISC microcontroller running at 40 MHz with 16 KB (8K x 16) of on-chip Flash program memory, packaged in a 28-pin SOIC wide-body (SO) tube. It belongs to Microchip's low-voltage "LF" PIC18J family, designed for 2.0 V to 3.6 V operation from a single lithium-cell or regulated supply rail. What is a PIC18 microcontroller? A PIC18 is Microchip's enhanced 8-bit Harvard-architecture RISC microcontroller family, positioned above the PIC16 mid-range and below the PIC24/dsPIC 16-bit families. Within the taxonomy it belongs to microcontroller -> embedded MCU -> semiconductor IC. PIC18 devices add 16-bit wide instructions, hardware multiply, linear program memory, and C-friendly addressing, while keeping the deterministic instruction cycle that PIC parts are known for. The PIC18LF24J10 specifically targets low-voltage, high-performance designs that need rich communication peripherals (USART with LIN, two SSP ports with I2C address masking) at modest memory cost. Key features include 16 KB Flash, 1024 bytes of SRAM, 256 bytes of EEPROM, 25 digital I/O pins, 10-bit A/D converter with up to 10 channels, two analog comparators, an enhanced USART, two MSSP ports, and Microchip's nanoWatt power-management technology with multiple idle and sleep modes. The 40 MHz internal oscillator (10 MIPS throughput) eliminates an external crystal in many designs and simplifies BOM. Architecture highlights: the PIC18LF24J10 uses a 16-bit instruction word with a single-cycle ALU, a 31-level hardware stack, and a priority-enabled interrupt controller. The 10-bit ADC delivers up to 10 channels through a shared sample-and-hold, and the nanoWatt feature set (RC_RUN, SEC_RUN, SEC_IDLE, sleep) lets the device draw only a few microamps in standby, making it a strong fit for battery-powered or energy-harvesting products. Typical applications include industrial sensor interfaces, low-power handheld instruments, USB-to-UART bridges (when paired with a USB transceiver), home-automation nodes, automotive body controllers (non-safety), and small appliances requiring LIN or I2C sensor networks. The 28-pin SOIC footprint is friendly to hand-soldering and through-pin replacement on legacy boards. Design consideration: when migrating from the PIC18F24J10 to this "LF" variant, verify that VDD never exceeds 3.6 V — the F-version supports 4.2 V to 5.5 V while the LF version is restricted to 2.0 V to 3.6 V. Always place a 0.1 uF decoupling capacitor as close as practical to VDD/SS and a 10 uF bulk capacitor near the supply pin.

The Microchip Technology PIC18LF24J10-I/SP is an 8-bit PIC18J-series RISC microcontroller running at 40 MHz with 16 KB of Flash program memory (8K x 16), housed in a 28-pin SPDIP (through-hole DIP) package. It supports a wide operating voltage range of 2.0 V to 3.6 V (LF series, low-voltage variant) and integrates 1024 bytes of SRAM, making it well suited for low-power and battery-friendly embedded designs. The 'I' suffix denotes the industrial temperature grade of -40C to +85C. A PIC microcontroller (Programmable Interface Controller) is a compact embedded processor that combines a CPU core, Flash program memory, SRAM, EEPROM, and rich on-chip peripherals (UART, SPI, I2C, ADC, timers, PWM) into a single IC. PIC18 devices sit in the upper tier of Microchip's 8-bit portfolio, featuring an enhanced instruction set, hardware multiplier, and C-friendly architecture that bridges hobby and professional embedded development. Within Microchip's hierarchy they are positioned above PIC10/12/16 baseline and mid-range devices and below the 16-bit dsPIC and 32-bit PIC32 families. The PIC18LF24J10 family delivers up to 40 MHz operation from internal oscillator, 10-bit ADC, two USART modules, MSSP (SPI/I2C), two analog comparators, and nanoWatt power management features for sleep-mode current reduction. On-chip in-circuit serial programming (ICSP) and debug interfaces shorten development cycles with Microchip's MPLAB X IDE and PICkit/Snap tools. The 'J10' silicon variant is part of the PIC18 'J' family which targets cost-sensitive, low-voltage, low-power applications with internal oscillator flexibility. Designers migrating between PIC18LF24J10, PIC18LF25J10, PIC18LF26J10, and PIC18LF27J10 (more Flash and RAM) can preserve board layout while scaling memory. Typical applications include consumer electronics, industrial control, USB peripherals (with on-chip transceiver on some variants), sensor hubs, home appliances, and low-power IoT edge nodes. The 28-pin SPDIP package is favored for through-hole prototyping, educational kits, and ruggedized industrial assemblies. For volume production, the same die is offered in SOIC-28 (SO), QFN-28 (ML), and TQFP-44 footprints. Key design consideration: route the ICSP clock/data lines to a 5-pin header with proper isolation resistors to allow in-circuit debugging without programmer interference. The LF (low-voltage) variant cannot be operated above 3.6 V - choose the PIC18F24J10 (5 V tolerant) variant for 5 V rails or mixed-voltage systems.

The Microchip Technology PIC18LF24J50-I/SP is a low-power, high-performance 8-bit PIC18 microcontroller with integrated full-speed USB 2.0 (12 Mbps), 16 KB of Flash program memory, 4 KB of RAM, and an enhanced instruction set, housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The LF suffix indicates the low-voltage variant supporting 2.0V to 5.5V operation, while the J50 family adds deep-sleep nanoWatt XLP power management that drops quiescent current to the microamp range for battery-powered designs. The core runs up to 48 MHz internal clock (12 MIPS) with hardware multiplier, 16-bit data path, and C compiler-friendly orthogonal architecture. The integrated USB 2.0 Full-Speed transceiver with on-chip pull-up resistors eliminates external PHY components for HID, CDC, mass-storage, and vendor-class device designs. The microcontroller also includes a 10-bit ADC up to 250 ksps, multiple PWM modules, comparators, and the standard PIC18 peripheral set. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, RAM, and configurable I/O peripherals. Within the broader taxonomy, the PIC18LF24J50-I/SP belongs to the 8-bit MCU category -> RISC microcontroller -> embedded controller -> semiconductor IC. The "LF" voltage class supports 2.0V-3.6V core operation natively while remaining 5.5V tolerant on digital I/O, bridging coin-cell and Li-ion battery designs with 5V-tolerant sensors and actuators without level translators. The "J" series designation refers to the enhanced peripheral set including the on-chip USB engine and deep-sleep XLP modes, while the "50" suffix denotes the USB 2.0 Full-Speed capable variant in the family. Key features include hardware Real-Time Clock Calendar (RTCC) with timestamps, 2 KB EEPROM emulation in Flash, Master Synchronous Serial Port (MSSP) supporting SPI and I2C, two Enhanced USART modules, charge time measurement unit (CTMU) for capacitive touch and mA-range current measurement, and configurable logic cells. The device supports self-programming via ICSP (In-Circuit Serial Programming) and runs the same MPLAB X IDE / XC8 toolchain as every other PIC18 part, simplifying firmware reuse across product lines. Typical applications include USB HID peripherals (keyboards, mice, custom input devices), CDC virtual COM ports, low-power sensor nodes, capacitive touch interfaces, battery-powered instrumentation, and industrial control nodes. The 5V-tolerant digital I/O makes the part directly compatible with 5V sensors without external level shifters. Trade-off consideration: at full 48 MHz the LF core requires the upper end of its 2.0V-3.6V rail, while deep-sleep operation preserves nanoamp quiescent current but disables USB - power profiles must be budgeted carefully for USB-suspended battery applications.

It runs at up to 48MHz internal clock speed and supports an operating voltage range of 1.8V to 3.6V, making it well suited for low-power and battery-operated designs. The device integrates 256 bytes of EEPROM data memory and offers rich peripheral integration for mixed-signal embedded applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and programmable I/O peripherals on one silicon die. The PIC18 family is Microchip's high-performance 8-bit RISC architecture family, featuring a modified Harvard bus, 16-bit opcodes, and an instruction pipeline that allows most instructions to execute in a single cycle. Within the PIC18 K-line portfolio, the LF sub-family emphasizes low-voltage and battery-aware operation, and the PIC18LF24K22 in particular targets applications where sleep-mode nanosecond quiescent current is critical. Key differentiating features include the nanoWatt XLP deep sleep mode with current consumption down to a few nanoamps, integrated mTouch capacitive touch peripherals, multiple Enhanced USART, MSSP (SPI/I2C) ports, and a 12-bit A/D converter with up to 17 channels. The device also offers two analog comparators, a hardware RTCC, and the standard PIC18 CTMU charge-time measurement unit for precise time-of-flight or capacitive touch sensing. The wide SOIC package gives 28 pins of I/O and supports surface-mount assembly on standard 300-mil wide SOIC-28 land patterns. Architecturally, the PIC18LF24K22 uses a 16-bit modified Harvard RISC core with 31-level hardware stack, deterministic interrupt latency, and a vectored interrupt controller. The Flash memory is self-programmable under software control, allowing boot-loader or in-application firmware updates. The XLP power-management block includes ultra-low-power wake-up sources, on-board voltage regulator, and configurable sleep/wake states managed through the PCL, T0CON, and WDTCON registers. Typical applications include portable consumer electronics, battery-powered wireless sensor nodes, capacitive touch user interfaces, motor control for low-power BLDC and stepper drivers, HVAC thermostat controllers, and medical monitoring peripherals where extended battery life is essential. The -40C to +125C operating range and low-power design also suit automotive body electronics and industrial sensor front-ends. When designing with this part, observe the 1.8V minimum VDD for Flash programming, place a 100nF decoupling capacitor adjacent to each power pin, and follow Microchip's recommended layout for the analog and oscillator pins to avoid noise coupling into the ADC. The MSSP pins share I/O ports, so firmware must configure the correct PPS mapping for SPI vs I2C operation.
