It operates at up to 48MHz clock speed delivering 12 MIPS, supports 2.0V-3.6V core supply voltage, and includes a 10-bit ADC, multiple timers, and Microchip's nanoWatt XLP extreme low-power technology. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals on one silicon die. The PIC18 family is Microchip's enhanced 8-bit architecture sitting between baseline PIC10/12/16 and the 16-bit PIC24/dsPIC families. The 'LF' prefix denotes a wide-voltage low-power variant, the 'J' suffix indicates the J-series family with integrated USB, and '53' identifies the specific die with 64KB Flash. The PIC18LF26J53 belongs to the power management hierarchy of low-power MCUs used in battery-operated and USB-connected products. Key features include 64KB (32K x 16) Flash program memory, 4KB RAM, 22-channel 10-bit ADC, two analog comparators, enhanced CCP modules, four timers, two I2C, two SPI, and a full-speed USB 2.0 device/host/OTG transceiver. The device integrates a 3.3V voltage regulator for USB operation and supports deep sleep current below 100nA via nanoWatt XLP technology. The PIC18LF26J53 uses an enhanced Harvard RISC architecture with a 16-bit instruction word and 8-bit data path. The 48MHz internal oscillator with 4x PLL eliminates external crystals in most designs, and the integrated USB transceiver eliminates external USB PHY chips. The wide 2.0V-3.6V supply range with internal 3.3V regulation supports single-cell Li-ion or two-AA battery designs. Typical applications include USB peripherals, sensor hubs, low-power wireless sensor nodes, industrial data loggers, HID-class USB devices, and consumer electronics with USB connectivity. The combination of integrated USB, deep-sleep nanoWatt XLP modes, and rich peripherals makes it well-suited for cost-sensitive USB-aware embedded products. When designing with this device, note that the 28-SOIC package is the most common variant; for USB designs with dedicated D+/D- pins routing, follow the datasheet's PCB layout recommendations for the integrated 3.3V regulator. Designers should also verify the 'LF' supply voltage window (2.0V-3.6V) versus the non-LF 'F' variant (down to 2.0V) when selecting parts for 5V-tolerant applications.

PIC18LF26J53T-I/ML

PIC18LF26J53T-I/ML - 64KB Flash USB MCU, 28-QFN | Microchip

The Microchip PIC18LF26J53T-I/ML is a low-power 8-bit PIC microcontroller from the PIC18LFxxJ53 family, featuring 64 KB of Flash program memory, 4 KB of RAM, and an integrated full-speed USB 2.0 transceiver. Housed in a 28-pin QFN package (ML, 6x6 mm), the device operates from 2.0 V to 2.75 V and delivers up to 12 MIPS throughput. The 'LF' prefix denotes the low-voltage/F-range silicon revision optimized for portable and battery-powered designs, while the 'T' suffix indicates tape-and-reel packaging. What is a PIC18 microcontroller? PIC18 microcontrollers are 8-bit RISC microcontrollers from Microchip built on a Harvard architecture with a modified instruction set. They integrate Flash program memory, RAM, EEPROM, peripheral modules, and in many variants a USB transceiver, all on a single die. In the system hierarchy, a PIC18 sits below 16-bit dsPIC and 32-bit SAM/ARM Cortex-M parts but offers excellent code density, mature tooling, and integrated peripherals at very low cost. Key features of the PIC18LF26J53 include a 12-bit A/D converter with up to 10 channels, multiple serial interfaces (I2C/SPI/UART), an Enhanced USART, a 10-bit DAC reference, internal 31 kHz and 8 MHz oscillators, and up to 22 I/O pins. The integrated USB 2.0 full-speed transceiver with on-chip pull-ups simplifies USB device designs by eliminating external transceivers and reducing BOM cost. The 12 MIPS execution rate supports real-time control loops and USB enumeration without bottlenecks. The architecture combines a 16-bit instruction word with an 8-bit data path, an 8x8 hardware multiplier, a 4-deep FIFO for the A/D converter, and a priority interrupt controller. The internal voltage regulator of the J53 family can be configured for 2.5 V or 3.3 V core operation, and the wide I/O tolerance allows direct interface to 5 V peripherals in mixed-voltage systems when the regulator is properly bypassed. Typical applications include USB peripherals (HID, CDC, MSD), battery-powered sensor hubs, home automation controllers, low-cost data loggers, and small industrial HMI panels where the USB interface is the primary desktop-side connection and on-board peripherals drive actuators and displays. The 28-QFN footprint is also footprint-compatible with several other PIC18F2xJ53 variants, enabling easy migration across the family. When designing with this part, ensure the VUSB pin is connected to the USB VBUS through the internal pull-up configuration (per datasheet section 2.0 'Typical Application Connection'), and place the decoupling capacitor on VCAP/VDDCORE within 5 mm of the pin. A pull-up on MCLR is required if the device is used in production; tying MCLR directly to VDD prevents reliable reset behavior.

The Microchip Technology PIC18LF26J53T-I/SO is a low-power 8-bit microcontroller from the PIC18 LF J53 family, featuring integrated USB 2.0 full-speed peripheral support and 64KB of Flash program memory in a 28-pin SOIC wide (7.50 mm) package. The device operates up to 48 MHz (12 MIPS instruction throughput) from a 2.0V to 3.6V supply and includes 4KB RAM, 12-bit A/D converter with up to 10 channels, multiple timers, and two USART/SPI/I2C peripherals. The "LF" prefix indicates the low-voltage core variant optimized for eXtreme Low Power (XLP) battery applications, while "T" denotes tape-and-reel packaging and "I" denotes the industrial -40C to +85C temperature range. An 8-bit PIC microcontroller is a Harvard-architecture RISC processor designed for embedded control. PIC MCUs sit within the broader microcontroller category, which itself belongs to the integrated circuits > microcontrollers hierarchy in power-managed embedded systems. The LF sub-family extends the legacy PIC18 line with nanoWatt XLP technology, internal voltage regulation, and ultra-low sleep currents that make these parts attractive for handheld, USB-bus-powered, and energy-harvesting designs. Key features include the integrated USB 2.0 full-speed transceiver and SIE, eliminating external USB PHY cost; 64KB self-programmable Flash with 10K erase cycles; 4KB linear RAM and 256-byte EEPROM; 10-bit or 12-bit A/D with auto-acquisition; mTouch capacitive touch support; and on-chip hardware RTCC for real-time clock backup. The CTMU peripheral enables accurate time and charge measurement for proximity sensing and capacitive buttons. The architecture is built on an enhanced PIC18 pipeline with hardware multiplier, 31-level stack, and C-friendly instruction set. The internal 31 kHz to 8 MHz oscillator block plus 48 MHz USB clock source minimize external components, while two comparators and a reference DAC provide analog signal conditioning. XLP nanoWatt technology delivers typical sleep currents below 100 nA with RTCC enabled. Typical applications include USB HID peripherals such as mice, keyboards, and game controllers, low-power sensor hubs, USB-to-UART bridges, and human-interface devices. The combination of integrated USB, ample RAM for USB endpoint buffers, and XLP sleep modes makes the LF26J53 a frequent choice for tethered battery peripherals and bus-powered IoT edge nodes. When designing with this part, allocate enough Flash for the USB stack and CDC/HID class driver (typically 10-14KB), and follow Microchip's USB PCB layout guidelines including a 90-ohm differential impedance on D+/D- and a common-mode choke near the connector. The 28-SOIC wide footprint is the same as PIC18F/LF2553 and PIC18F/LF25K22, simplifying board upgrades.
