PIC18LF2610T-I/SO

PIC18LF2610T-I/SO - 8-bit 40MHz PIC MCU 64KB Flash | Microchip

The Microchip Technology PIC18LF2610T-I/SO is an 8-bit PIC18F-series RISC microcontroller with a 40 MHz maximum operating frequency, 64 KB (32K x 16) of Flash program memory, and 3.8 KB of RAM, housed in a 28-pin SOIC (SO) package supplied on tape and reel. It is the LF (low-voltage/F-version) variant with a 2.0 V to 5.5 V operating range, and it integrates peripherals including I2C, SPI, UART/USART communications, a 10-bit ADC, multiple timers, and 25 I/O pins. What is a PIC18 microcontroller? A PIC18 is an 8-bit RISC microcontroller from Microchip Technology built on an enhanced Harvard architecture with 16-bit instructions. PIC18F devices sit in the middle of the Microchip 8-bit portfolio (above baseline PIC10/12/16 and below the 16-bit dsPIC/PIC24 and 32-bit PIC32 lines), combining cost-effective 8-bit processing with rich peripherals, Flash program memory, and nanoWatt power-saving modes for industrial and consumer embedded designs. Key features include 64 KB of self-programmable Flash for in-field firmware updates, 3.8 KB of data SRAM, a hardware USART supporting RS-232/RS-485, an MSSP module configurable as SPI or I2C (master or slave), a 10-bit ADC with up to 8 input channels, two 8-bit timers plus three 16-bit timers, and nanoWatt Technology with multiple idle/sleep modes for low-power battery applications. The /SO suffix indicates a wide-body 300-mil SOIC package, while the T suffix denotes tape-and-reel packaging for high-volume SMT assembly. The architecture uses a 16-bit instruction word with an 8-bit data path and a 31-level hardware stack, allowing deterministic interrupt response and C-compiler-friendly code density. The LF suffix designation extends VDD operation down to 2.0 V, making the part suitable for 2x AA battery or 3.3 V regulated-rail designs while remaining software- and pin-compatible with the standard F (PIC18F2610) variant running at 4.2 V to 5.5 V. Typical applications include industrial control modules, automotive body and HVAC subsystems, low-power sensor nodes, USB-to-serial bridges, brushless-DC motor controllers, white-goods user interfaces, and consumer appliances where a 5 V-tolerant 8-bit MCU with on-chip Flash simplifies BOM and firmware lifecycle. Designers should note that code developed for PIC18F2610 ports directly to PIC18LF21 because both share peripherals and pinout, but FFS (Fail-Safe Clock Monitor) and two-speed start-up modes behave differently in LF devices at low VDD. The 28-SOIC package has a thermal resistance theta-JA of approximately 80 C/W, so continuous 40 MHz operation at 85 C ambient requires verifying that peripheral drive current remains within Microchip derating curves.

The Microchip Technology PIC18LF2680-I/SP is an 8-bit PIC18F-family Flash microcontroller with integrated ECAN (Enhanced Controller Area Network), 64KB of program Flash memory, and 3328 bytes of RAM, housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. It runs at up to 40 MHz CPU clock from a 2.0V to 3.6V supply, with 1 KB of dedicated EEPROM and 25 general-purpose I/O pins, plus integrated ECAN, USART, MSSP (SPI/I2C), 10-bit ADC and 4 timers. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, I/O peripherals, and sometimes communication interfaces on one die. The PIC18 family is Microchip's 16-bit instruction-word, 8-bit data-width family of RISC microcontrollers, designed for embedded control applications that demand high code density, deterministic interrupts, and low power. The 'LF' prefix denotes the low-voltage variant optimised for 2.0V to 3.6V operation, while the 'F' variant typically runs from 4.2V to 5.5V. MCUs sit at the lowest tier of the embedded-computing hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor IC. Key features of the PIC18LF2680-I/SP include on-chip ECAN 2.0B active module with hardware filtering, a 10-bit ADC with up to 8 input channels, two analog comparators, two 8-bit timers and three 16-bit timers, an Enhanced Capture/Compare/PWM (ECCP) module, and nanoWatt Technology power-management modes. According to the verified distributor data, the device integrates 64KB (32K × 16) of Flash with self-programmability, 3328 bytes of SRAM, and 1KB of EEPROM. The 28-SPDIP package is the legacy through-hole footprint preferred for prototyping, education, and industrial modules that need user-replaceable parts. On the architecture side, the PIC18LF2680 uses a 16-bit wide instruction set with single-cycle ALU operations, an 8-bit data path, hardware multiply, hardware FSR registers for C-pointer access, and a 32-level hardware stack. The ECAN engine implements ISO 11898-1 compliant CAN 2.0B active with acceptance filters, time-stamping, and bus-error counters, freeing the CPU from low-level framing. Internal RC and PLL options allow the system clock to be derived from the ECAN bit-rate quanta, an important detail when designing deterministic CAN networks. Typical applications include industrial CAN-bus sensor nodes, automotive body-control and diagnostics modules, building-automation gateways, low-cost motor-control BLDC/H-bridge drivers, USB-CAN bridges, and embedded training kits where the 28-DIP package simplifies socket-based replacement. Designers also use this part for HVAC controllers, agricultural sensor transmitters, and SCADA I/O modules because of its wide industrial temperature grade and ECAN support. Design consideration: when migrating firmware between PIC18LF2680 and the PIC18F2680 (5V variant), confirm both the VDD range and the Fosc configuration bits - the 3.3V regulator must not exceed 3.6V. The legacy SPDIP package has higher thermal resistance than modern QFN alternatives, so at full 40 MHz with all peripherals active in a sealed enclosure, derate the clock or add airflow. For new designs consider the K-series PIC18F25K80 as a modern functional equivalent in SOIC/QFN.

PIC18LF26J11-I/SO - 8-Bit 48MHz 64KB Flash XLP MCU | Microchip
PIC18LF26J11-I/SO

PIC18LF26J11-I/SO - 8-Bit 48MHz 64KB Flash XLP MCU | Microchip

The Microchip Technology PIC18LF26J11-I/SO is a low-power 8-bit PIC18 microcontroller from the eXtreme Low Power (XLP) family, featuring 64KB Flash program memory and 48MHz internal operation in a 28-pin SOIC wide package. Operating from 2.0V to 3.6V, the 'LF' variant is optimized for battery-backed applications and delivers up to 12 MIPS throughput at 48MHz. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), non-volatile EEPROM, and a rich set of on-chip peripherals such as timers, ADC, communication interfaces, and I/O. The PIC18LF26J11 sits within the PIC18 RISC family and belongs to the power-management-IC-adjacent hierarchy of embedded controllers; PIC18 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Its XLP designation targets ultra-low standby current (<100 nA typical) for energy harvesting, IoT, and portable consumer products. Key features include 64KB (32K x 16) self-programmable Flash with 10K Erase/Write cycles, 4KB SRAM, an internal 31 kHz to 8 MHz oscillator with PLL (x4) reaching 48 MHz, 10-bit ADC with up to 10 channels, two analog comparators, two USART/SPI/I2C modules (ECCP/CCP/SSP), and a 16-bit Enhanced Capture/Compare/PWM peripheral. The 28-SOIC (0.295" / 7.50 mm) package is industrial-grade rated -40C to +85C and offers an easy migration path to other PIC18LF26/25/24J11 variants. Architecturally the device uses a modified Harvard 8-bit RISC core with single-cycle 16-bit instruction fetch and 8-bit data path, which simplifies code density and deterministic timing. nanoWatt XLP technology adds deep sleep, sleep with RTCC, and idle modes to extend battery life. The integrated 31kHz-8MHz HF internal RC oscillator eliminates the need for an external crystal in many designs, reducing BOM cost. Typical applications include portable medical devices (glucose meters, pulse oximeters), low-power wireless sensor nodes, smart thermostats, USB HID peripherals, consumer appliances, and battery-powered IoT edge nodes. The combination of 12 MIPS throughput, XLP standby current, and a familiar PIC18 toolchain makes the part attractive for designers migrating from older 8-bit architectures. When designing with the PIC18LF26J11-I/SO, ensure the supply voltage never exceeds 3.6V (the LF version is not 5V tolerant like PIC18F26J11) and select the appropriate configuration bits for the internal oscillator vs. external crystal. The 28-SOIC wide footprint simplifies hand-prototyping and reflow soldering; for hand-assembly or breadboard work, consider the PIC18LF26J11-I/SP (SPDIP-28) variant.

PIC18LF26J11-I/SS - 8-bit 48MHz 64KB Flash XLP MCU | Microchip
PIC18LF26J11-I/SS

PIC18LF26J11-I/SS - 8-bit 48MHz 64KB Flash XLP MCU | Microchip

The Microchip PIC18LF26J11-I/SS is a low-power 8-bit PIC18 microcontroller from the PIC18 J-series family, featuring 64KB of Flash program memory, 4KB RAM, and a 48 MHz internal oscillator core delivering up to 12 MIPS instruction throughput, housed in an industrial-grade 28-pin SSOP package. Operating from a 2.0V to 3.6V supply (the LF family is the low-voltage variant), it integrates a 10-bit ADC, multiple PWM/Capture/Compare peripherals, and Microchip's nanoWatt XLP (eXtreme Low Power) technology for battery-driven applications. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. Within the broader semiconductor hierarchy, an MCU sits below microprocessors (MPUs) in compute complexity but adds on-chip Flash, RAM, and peripherals; within Microchip's portfolio it belongs to the PIC family, then to the 8-bit PIC18 sub-family, then to the J-series (high-performance, low-voltage), then to the LF (low-voltage) nanoWatt XLP subgroup. The 'J' in PIC18LF26J11 denotes the J-series, and the LF prefix specifically targets 2.0V-3.3V applications. Key features include 64KB (32K x 16) self-programmable Flash with Flash EEPROM emulation, 4KB RAM, 256 bytes of EEPROM, 10-bit ADC with up to 10 channels, 2 analog comparators, 2 MSSP (SPI/I2C) ports, 2 Enhanced USART modules, and deep-sleep current consumption in the nanoampere range. The 28-pin SSOP package provides 22 general-purpose I/O pins with Peripheral Pin Select (PPS), allowing digital peripheral functions to be remapped to any I/O. The PIC18LF26J11 uses a 16-bit modified Harvard architecture with an 8-bit data path. Its core executes most instructions in a single cycle (4 FOSC clocks) and supports priority levels for interrupts. PPS and Deep Sleep mode with Ultra Low Power Wake-up make this device highly flexible for energy-harvesting and battery-backed designs. Typical applications include low-power sensor nodes, IoT edge devices, battery-powered instrumentation, consumer electronics such as remote controls and toys, industrial control sub-modules, and any 3.3V system that needs deterministic 8-bit control with rich digital connectivity. When designing with this part, pay attention to the 3.3V supply ceiling (the LF prefix indicates the low-voltage family - the F variant without L runs to 5.5V), and use Microchip's MPLAB X development toolchain with the XC8 compiler. The 28-SSOP footprint is also shared with several other PIC18 J-series devices, easing PCB migration across memory tiers.

PIC18LF26J11T-I/ML

PIC18LF26J11T-I/ML - 8-Bit XLP MCU 64KB Flash 28-VQFN | Microchip

The Microchip PIC18LF26J11T-I/ML is an 8-bit PIC® XLP™ eXtreme Low Power microcontroller with 64KB Flash, 4KB RAM, and 48MHz operation, housed in a 28-pin VQFN package with exposed thermal pad. Designed for ultra-low-power embedded applications, the device operates from 2.0V to 3.6V and supports industrial temperature ranges. This Tape-and-Reel variant is pin-compatible with the tray-packaged PIC18LF26J11-I/ML sibling, sharing identical silicon and peripheral set. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and configurable peripherals on one die. Within the broader semiconductor hierarchy, the PIC18LF26J11 belongs to the 8-bit microcontroller category, which sits between 4-bit legacy controllers and 32-bit Cortex-M0+/M4 devices. The 18J sub-family adds nanoWatt XLP technology that drops standby current to roughly 20nA, enabling battery-powered designs that previously required external RTC chips. Key differentiating features include 64KB on-chip Flash organized as 32K×16, 12 MIPS throughput from the 48MHz internal oscillator, a 10-bit ADC with up to 13 channels, two analog comparators, two USART modules, two SPI/I2C peripherals, and a 16-bit timer/counter bank. The integrated nanoWatt XLP power management block supports multiple idle and sleep modes down to 20nA, while the internal voltage regulator eliminates the need for an external 3.3V LDO in most designs. Architecturally, the PIC18LF26J11 uses a RISC Harvard-style core with single-cycle instruction execution at 48MHz (12 MIPS), 8×8 hardware multiply, and 16-bit-wide Flash bus for fast fetch. The 28-pin VQFN package exposes 34 I/O ports multiplexed across digital and analog peripherals, with a dedicated ICSP/ICD interface for in-circuit programming and debugging. The exposed thermal pad improves theta_JA for higher-current GPIO scenarios. Typical applications include portable medical sensors, IoT edge nodes, battery-powered wireless sensor nodes, USB human-interface devices, home automation controllers, and low-power industrial HMI panels. The XLP feature set is especially suited to coin-cell applications where multi-year battery life is required. When designing with this part, prefer the smallest possible active duty cycle and route the exposed pad to a continuous ground pour to maximize heat dissipation. Always validate that your compiler version supports the 18J silicon; older MPLAB 8.x builds may require recompilation for the 26J11 silicon revision.

PIC18LF26J11T-I/SO - 64KB Flash 8-bit MCU, nanoWatt XLP | Microchip
PIC18LF26J11T-I/SO

PIC18LF26J11T-I/SO - 64KB Flash 8-bit MCU, nanoWatt XLP | Microchip

The Microchip PIC18LF26J11T-I/SO is an 8-bit PIC18J-series microcontroller with 64KB Flash, 4KB RAM, and nanoWatt XLP technology, housed in a 28-pin SOIC wide (0.295 in, 7.50 mm width) package. It executes instructions at up to 12 MIPS (48 MHz internal clock from the PLL) and operates from 4.2 V to 5.5 V, providing drop-in compatibility for 5 V PIC18 LF applications. The part delivers enhanced flash, 34 I/O pins, a 10-bit ADC with conversion capabilities, and an on-board RTCC for time-keeping with a separate 32 kHz crystal. An 8-bit PIC microcontroller belongs to the broader family of RISC microcontrollers (Reduced Instruction Set Computer) - integrated circuits that fetch, decode, and execute simplified instruction sets in typically one clock cycle. The PIC18F/LF sub-family adds a 16-bit instruction word on a modified Harvard architecture, where program and data buses are separate, allowing simultaneous instruction fetch plus data access. Within this hierarchy, PIC18LF26J11 sits at the boundary between full-performance (PIC18F) and low-power (PIC18LF) variants, and the J-suffix indicates the use of nanoWatt XLP technology and a segmented flash architecture originally derived from the PIC18F46J11. Key features include 64KB (32K x 16) of flash program memory, 4 KB SRAM data memory, 34 digital I/O pins shared with peripherals, a 10-bit analog-to-digital converter, multiple serial interfaces (I2C, SPI, USART with LIN support), and two analog comparators. The RTCC block supports time-of-day with an external 32 kHz crystal, useful for time-stamped data logging on battery-powered systems. NanoWatt XLP extreme-low-power technology delivers sleep currents in the microampere range, allowing several years of operation from coin cells. The voltage regulator of the LF J-series is internal, supporting the 2.0 V to 5.5 V (F: 2.0 V to 3.6 V, LF: 4.2 V to 5.5 V) operating ranges documented for the family. Designers should consult the data sheet for voltage-mode selection when migrating between F and LF variants. Typical applications include portable medical instruments, environmental sensor nodes with time-stamped data logging, HVAC controls, USB device controllers (with PIC18 USB variants), industrial control loops, and automotive body modules. The wide SOIC-28 footprint eases hand-soldering for prototype and rework, while the industrial temperature range (-40 C to +85 C) supports most non-automotive deployments. When designing with this device, ensure the supply voltage stays within 4.2 V to 5.5 V. Decouple VDD with 100 nF plus 10 uF bulk capacitors placed close to the pins, and consider adding a ferrite bead for noise-sensitive ADC channels. Use the ICD 3 or PICKit 3 for in-circuit programming via the ICSP interface.
