PIC18LF2410T-I/ML - 16KB Flash 8-bit MCU 40MHz QFN-28 | Microchip
MPN： PIC18LF2410T-I/ML ✓ 啟用中PIC18LF2410T-I/ML 概覽
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, on-chip Flash program memory, RAM, peripherals, and a CPU core. Within the broader taxonomy, an MCU sits below microprocessor and above discrete logic; the PIC18 family sits in Microchip's mid-range 8-bit portfolio, above PIC10/12/16 baseline parts but below PIC24/dsPIC and PIC32 (32-bit) families. The "LF" series adds NanoWatt sleep modes for battery-powered designs, while the "F" (without L) variant is the 4.2-5.5V-only counterpart.
Key features of this device include 16KB (8K x 16) of self-programmable Flash, 768 bytes of SRAM, a 10-bit ADC with up to 10 channels, an internal oscillator selectable from 31 kHz to 8 MHz, fail-safe clock monitoring, and a hardware 8x8 single-cycle multiplier. Enhanced peripherals include multiple USART, MSSP (SPI/I²C), CCP/ECCP modules, and NanoWatt power management with multiple idle and sleep modes drawing microamp-level currents. The exposed thermal pad on the QFN-28 package reduces junction-to-ambient thermal resistance.
The PIC18 CPU uses a 16-bit instruction word with an 8-bit data path, a RISC-optimized Harvard architecture, and a C-friendly instruction set that includes a hardware 8x8 multiplier and a hardware divider. Internal oscillator support and fail-safe clock monitor provide clock redundancy, while self-programmable Flash enables in-application firmware updates without an external programmer.
Typical applications include industrial sensor interfaces, low-power battery-powered instrumentation, USB/HID peripherals, home appliances, and consumer devices requiring 8-bit processing with mixed-signal I/O. The wide 2.0-5.5V range suits both 3.3V and 5V designs with a single BOM line. The "T" suffix indicates Tape & Reel packaging, and the "-I" indicates an industrial -40°C to +85°C operating temperature range.
When designing with this device, validate that the 28-pin QFN land pattern matches your PCB footprint and confirm the -I temperature grade suits your environment. Designers transitioning from PIC18F2410 (non-LF) parts must verify regulator support for sub-4.5V operation.

典型應用
PIC18LF2410T-I/ML 適用於 6 應用s: Industrial Sensor Signal Conditioning, Battery-Powered Portable Instrumentation, Home Appliance Control, USB HID Peripherals, Automotive Body Electronics (Non-Safety), Consumer Electronics Control Boards.
Industrial Sensor Signal Conditioning
The PIC18LF2410T-I/ML fits industrial sensor signal conditioning with its 10-bit ADC, multiple 2.0-5.5V operation, and 25 digital I/O. Its 10 MIPS performance is sufficient to sample, filter, and linearize thermocouple, RTD, or strain-gauge sensor data in real time. The wide voltage range lets the same part interface with both 3.3V digital sensors and 5V analog front-ends, reducing BOM complexity. The QFN-28 (6x6) footprint with exposed pad enables compact PCB layouts while providing thermal headroom for industrial -40 to +85 C environments. Its fail-safe clock monitor ensures reliable operation even if the primary crystal oscillator fails, which is critical in factory-floor installations.

Battery-Powered Portable Instrumentation
The PIC18LF2410T-I/ML is well-suited for battery-powered portable instruments thanks to NanoWatt Technology with sleep currents in the microamp range. The 2.0-5.5V LF supply allows direct operation from a single Li-ion (3.7V nominal) or two AA cells without a boost regulator, improving system efficiency. The internal oscillator from 31 kHz to 8 MHz eliminates the need for an external crystal in many designs, further reducing quiescent draw. Real-time-clock-like operation with periodic wake-ups is straightforward using Timer1 with an external 32.768 kHz crystal. The QFN-28 (6x6) package fits handheld enclosures while the industrial temperature range supports outdoor and medical use cases.
推薦
Home Appliance Control
Home appliance control boards benefit from the PIC18LF2410T-I/ML's blend of ADC channels, PWM outputs, and serial interfaces. The 10-bit ADC handles temperature, humidity, and current sensing, while the CCP/ECCP modules drive TRIACs, MOSFETs, or relay coils for motor and heater control. MSSP supports both SPI displays and I²C sensor hubs, and the USART interfaces with Bluetooth or Wi-Fi modules for smart-appliance connectivity. The wide voltage range lets the same MCU work in 3.3V low-voltage logic sections and 5V driver sections of the appliance. The QFN-28 (6x6) footprint with exposed pad handles the modest thermal dissipation in enclosed appliance cabinets.
推薦
USB HID Peripherals
The PIC18LF2410T-I/ML can be paired with an external USB transceiver IC (e.g., MCP2200 or PIC18F14K50) to implement USB HID peripherals such as keyboards, mice, custom HID controllers, or industrial input devices. Its 16KB Flash and 768B RAM comfortably fit USB stack plus HID report logic for typical human-interface-device applications. The 10 MIPS CPU executes polling and report synthesis without bottlenecks, while internal oscillator support eliminates external USB-clock crystals in cost-sensitive HID designs. The 2.0-5.5V range supports bus-powered 5V devices and self-powered 3.3V accessories from the same firmware baseline. The QFN-28 (6x6) package enables compact dongle and embedded-HID form factors.

Automotive Body Electronics (Non-Safety)
For non-safety automotive body electronics such as interior lighting controllers, seat-control modules, HVAC blend-door actuators, and accessory multiplexers, the PIC18LF2410T-I/ML industrial variant (I/ECPIL) provides adequate robustness. Its -40 to +85 C industrial range suits cabin environments, and its 25 I/O pins interface directly with body-control switches, LED drivers, and LIN/MCP2515 CAN transceivers. The wide voltage range tolerates 12V battery transients when paired with an external TVS and LDO. The hardware 8x8 multiplier accelerates CAN-message processing when bridging CAN-LIN networks. The QFN-28 (6x6) package supports the small PCB footprints typical of distributed body modules.
推薦
Consumer Electronics Control Boards
Consumer electronics from smart-home hubs to small appliances use the PIC18LF2410T-I/ML as a low-cost main controller. The PIC18 core runs user-interface firmware, drives character or graphical OLED/LCD displays over SPI/I²C, scans keypads, and controls buzzer/relay outputs. The hardware multiplier and 10 MIPS throughput handle basic animation and touch-panel response. The 2.0-5.5V supply accommodates 1-cell Li-ion, 2-cell alkaline, and USB-powered designs. Tape & Reel packaging supports high-volume SMT assembly, and the QFN-28 (6x6) footprint with exposed pad simplifies thermal management in sealed enclosures.

設計說明
Estimated: at 40 MHz and 5 V supply with all peripherals active, the PIC18LF2410 typically draws about 16 mA, falling below 1 uA in Sleep mode with Timer1 running off a 32.768 kHz crystal. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the QFN pin. For low-noise analog performance, add a 10 uF bulk capacitor on the analog AVSS rail if used.
The 28-pin QFN (ML) package has an exposed thermal pad that MUST be soldered to a PCB ground pad of at least equal size to the package EP for mechanical reliability and thermal dissipation. Without EP soldering, the package can refloat or fracture during thermal cycling. Use an array of micro-vias in the EP pad to stitch thermal conductivity to inner ground planes. Keep high-speed traces (crystal, ICSP) short and away from analog ADC inputs.
Three common pitfalls: (1) Confusing the LF (2.0-5.5V) variant with the F (4.2-5.5V) variant when designing 3.3V systems - the F variant will fail to start at low battery voltage. (2) Forgetting the MCLR pull-up resistor on pin 27 /RE3-MCLR - leaving MCLR floating causes erratic resets. (3) Using the wrong configuration bits for the internal oscillator - selecting HS instead of INTOSC prevents the part from running without a crystal.
Place the decoupling capacitor and any external crystal or resonator as close as possible to the OSC1/OSC2 pins (pins 7 and 8 on this QFN-28). Keep the ICSP clock (PGC, pin 17) and ICSP data (PGD, pin 18) traces clear of switching power traces to avoid in-circuit programming failures. Reserve a 6-pin header footprint (VPP, VDD, GND, PGD, PGC, AUX) for ICSP even in production boards to ease field firmware updates.
