PIC18LF24J10T-I/SS Übersicht
What is a PIC18 microcontroller? The PIC18 family is Microchip's 8-bit enhanced Harvard-architecture RISC microcontroller line, belonging to the broader category of microcontrollers -> microprocessors -> embedded processors -> semiconductors. PIC18 parts add 16-bit-wide instructions, an 8x8 hardware multiplier, and a richer peripheral set compared with baseline PIC16 parts, making them suited to mid-complexity embedded control tasks. Microchip is the global leader in 8-bit MCU shipments, and PIC18 devices are widely used in industrial, consumer, and automotive body-electronics applications.
Key features include a 10-bit ADC with up to 10 input channels, two analog comparators, two CCP (Capture/Compare/PWM) modules, five timers, an EUSART, and an MSSP (Master Synchronous Serial Port) configurable for SPI or I2C. The device also exposes up to 21 general-purpose I/O lines and integrates the nanoWatt power-management block with multiple Idle and Sleep modes for low-power applications. In-circuit debugging via ICD/ICSP is supported directly on the production PCB.
Typical applications include low-power sensor nodes, USB HID peripherals (with external interface), battery-powered handheld instrumentation, and industrial control modules operating from a 3.3V rail. The wide operating voltage range and rich peripheral mix make it a common drop-in for designs that need deterministic 8-bit performance without the cost of a 32-bit MCU.
When designing with this part, confirm the target board rail falls between 2.0V and 3.6V (the LF variant is not 5V tolerant - use PIC18F24J10 for 5V rails). Decouple VDD with a 100nF ceramic plus 10uF bulk capacitor placed within 5mm of the pins. For low-power designs, switch to RC_IDLE or Sleep during idle windows to draw single-digit microamp currents.

Typische Anwendungen
PIC18LF24J10T-I/SS ist geeignet für 6 Anwendungs: Battery-Powered Sensor Node, Industrial Control Module, USB HID Peripheral Controller, Handheld Test Instrumentation, Consumer Appliance Control Board, Educational and Prototyping Platform.
Battery-Powered Sensor Node
The PIC18LF24J10T-I/SS is well-suited to battery-powered sensor nodes because its 2.0V-3.6V supply range and sub-100nA Sleep current enable multi-year coin-cell operation, while the 10-bit ADC with up to 10 channels captures sensor inputs without an external mux. The EUSART and MSSP (SPI/I2C) connect directly to common low-power radios (LoRa, BLE modules) and digital sensors (BME280, MAX17048 fuel gauge). At 40MHz the MCU can wake, take a reading, transmit, and return to Sleep within a few milliseconds, achieving average currents in the single-digit microamp range. The 16KB Flash comfortably holds a state-machine application with OTA-friendly bootloader space, and the 28-pin SSOP fits compact sensor PCBAs.
Empfohlen
Industrial Control Module
For 3.3V industrial control modules, the PIC18LF24J10T-I/SS delivers deterministic 8-bit performance with 40MHz throughput, five timers for PWM and quadrature decoding, and 21 GPIO for relay drivers, status LEDs, and switch matrices. The two CCP/PWM modules can generate complementary PWM for motor or solenoid control, while the two analog comparators handle fast over-current or over-temperature trip signals without CPU intervention. The EUSART interfaces to RS-485 transceivers (like MAX485) for fieldbus communication, and the MSSP supports SPI to isolated gate drivers. The -40C to +85C industrial temperature range and robust PIC18 architecture suit factory-floor environments.
Empfohlen
USB HID Peripheral Controller
While the PIC18LF24J10T-I/SS lacks on-chip USB, it can still serve as a USB HID peripheral controller paired with external interface ICs such as the MCP2200 USB-to-UART bridge or the MCP2515 CAN-to-SPI controller. The MCU's EUSART streams HID reports from the host PC at full speed, the MSSP handles SPI configuration, and 21 GPIO drive buttons, LEDs, encoders, or analog joysticks. Designers favor this architecture when the application already needs the LF24J10's 16KB Flash for complex HID mapping firmware plus RS-232/UART connectivity for legacy equipment. Compared with native USB parts (PIC18F14K50), this setup trades BOM cost for code space and peripheral flexibility.
Empfohlen
Handheld Test Instrumentation
Handheld DMMs, cable testers, and field calibration tools use the PIC18LF24J10T-I/SS because its 40MHz core runs real-time measurement loops (RMS calculation, threshold detection) with low latency, while the 10-bit ADC with 10 channels reads multiple sensor inputs. The PIC18LF24J10T-I/SS's low Sleep current preserves battery life when the unit is idle in a toolbox, and the EUSART streams measured values to a host PC for logging. The 28-pin SSOP package allows the MCU, display driver, and op-amp signal chain to fit on a compact PCB behind an LCD, with GPIO remaining for keypad scanning and rotary encoder inputs.
Empfohlen
Consumer Appliance Control Board
Coffee machines, blenders, washing machines, and air purifiers use the PIC18LF24J10T-I/SS to drive user interfaces (buttons, rotary encoders, LED indicators) and to PWM-control DC motors, solenoids, and heaters. The two CCP/PWM modules generate complementary or independent PWM channels for variable-speed fans or proportional valves, while the five timers handle key debounce, watchdog, and low-frequency control loops. The PIC18LF24J10T-I/SS's low-voltage operation suits battery backup circuits and modern SMPS-derived 3.3V rails, and the 28-SSOP package is widely accepted in consumer electronics assembly lines.
Empfohlen
Educational and Prototyping Platform
The PIC18LF24J10T-I/SS appears on academic development boards and hobbyist trainers because the 28-SSOP package is breadboard-friendly with breakout boards, and the MPLAB X IDE + XC8 compiler + PICkit 3/4 toolchain are free and well-documented. Students learn ADC sampling, timer-based PWM, EUSART printf debugging, and interrupt-driven firmware on the same chip that is used in real commercial products, lowering the learning curve. The 16KB Flash is large enough to host moderately ambitious projects (PID controllers, audio effects, mini-OS kernels) without outgrowing the device, while the 3.3V operation protects against common 5V-only mistakes beginners make.

Wichtigste Unterscheidungsmerkmale

- Lowest Sleep current class for PIC18 family (vs. PIC18LF23K22T-I/SS)
- 16KB Flash vs 8KB on newer K22 family (vs. PIC18LF23K22T-I/SS)
Designhinweise
The LF suffix is the most important spec to verify: PIC18LF24J10T-I/SS accepts 2.0V to 3.6V only - it is NOT 5V-tolerant. Connecting 5V to any I/O or to VDD will damage the part. For 5V designs, use PIC18F24J10T-I/SS instead. Place a 100nF X7R decoupling cap within 5mm of VDD pin 5 and a bulk 10uF tantalum or ceramic on the same rail. Tie AVDD (pin 25) directly to VDD and AVSS (pin 26) directly to VSS; if analog noise is a concern, add a ferrite bead between digital and analog supplies.
Watch the I/O pin assignments when migrating from PIC18F to PIC18LF: although pinout-compatible at the SSOP level, the LF variant has weaker output drive on certain I/O when VDD drops below 2.5V. Do not assume logic-high thresholds identical to the F part when designing 3.3V-rail interfaces to 5V peripherals; add a level translator (TXS0108E or discrete MOSFET) if you must interface to 5V at the LF's nominal 3.3V. Also note the analog reference VREF+/VREF- is shared with AN3/AN2 - if you route a high-impedance reference, guard it from digital switching noise on adjacent pins.
For the 28-SSOP (5.30mm body, 0.65mm pitch), follow IPC-7351 SSOP land patterns: pad width 0.40mm, pad length 1.20mm, with a 0.65mm pitch. Stencil aperture should be roughly 0.45 x 1.30mm for laser-cut stencils. The exposed lead frames on SSOP have a long thermal path; if the MCU dissipates meaningful power (e.g., driving high-current GPIO loads), add 4 to 6 thermal vias under the SSOP body to a 2cm2 ground copper pour. For QFN (28-ML) variants, follow QFN landing guidelines with a center thermal pad array and 0.5mm pitch.
