MPN: PIC18LF24K22T-I/SO ✓ פעילPIC18LF24K22T-I/SO סקירה
A PIC microcontroller (MCU) is a compact programmable processor integrating CPU core, non-volatile Flash program memory, volatile RAM data memory, EEPROM/flash boundary, and a range of digital and communication peripherals on one die - intended for underwater MCU/embedded single board programming. It belongs to the broader category of 8-bit microcontrollers (PIC18 family) - 8-bit microcontrollers -> microcontrollers -> embedded ICs -> integrated circuits. PIC18 microcontrollers are widely adopted because they combine deterministic RISC architecture, low cost, rich peripheral integration, and mature toolchains.
Key differentiating specifications include: nanoWatt XLP extreme-low-power technology with typical sleep current below 100 nA, 16 MIPS performance at 64 MHz, 16 KB self-programmable Flash with high-endurance 100K erase/write cycles, 12-bit ADC with up to 17 channels, multiple communication peripherals (EUSART, MSSP SPI/I2C), and configurable on-chip capacitive mTouch sensing. The 28-pin SOIC wide package provides 1.27 mm pin pitch suitable for hand-soldering and moderate-density designs.
The PIC18LF24K22 family employs an enhanced Harvard RISC architecture with hardware multiplier and C compiler friendly instruction set. The LF designation indicates the low-voltage (1.8V min) variant, while the F variant runs 2.0V-5.5V. The device integrates mTouch capacitive touch support, PWM, comparators, and an RTC clock with calendar functionality, eliminating many external components in low-power sensor nodes.
Typical applications include battery-powered sensor nodes, portable medical devices, low-power IoT edge nodes, consumer remote controls, and industrial metering. The T-suffix tape-and-reel packaging (-T) is intended for high-volume automated assembly.
When designing with this device, ensure decoupling capacitors are placed within 5 mm of VDD/VSS pins and that unused I/O pins are configured as outputs to minimize current leakage. The 'T' in the suffix denotes tape-and-reel packaging for SMT assembly.

יישומים טיפוסיים
PIC18LF24K22T-I/SO מתאים עבור 6 יישוםs: Battery-Powered IoT Sensor Nodes, Industrial Metering and Data Loggers, Consumer Remote Controls and HIDs, Portable Medical Monitoring Devices, Automotive Body and Comfort Electronics, Smart Home and Building Automation.
Battery-Powered IoT Sensor Nodes
The PIC18LF24K22T-I/SO's nanoWatt XLP sleep mode (typical <100 nA) and 1.8V-3.6V LF supply range make it ideal for coin-cell powered wireless sensor nodes. Its 12-bit ADC and 16 MIPS performance handle periodic sensor reads, while the 64 MHz internal oscillator eliminates external crystals. The 28-SOIC wide footprint supports hand-reworkable prototyping and low-volume runs. Designers benefit from sub-1 uA average current when duty-cycling the EUSART to a sub-GHz radio.
מומלץ
Industrial Metering and Data Loggers
Industrial energy meters and temperature/humidity data loggers leverage the PIC18LF24K22T-I/SO's 256 B EEPROM for non-volatile calibration storage and 16 KB Flash for application firmware. The 12-bit ADC delivers <1 LSB INL for revenue-grade metering when paired with proper analog front-end design. The industrial -40 C to +85 C temperature range supports outdoor enclosures, and ICSP allows field firmware updates without disassembly.
מומלץ
Consumer Remote Controls and HIDs
TV remote controls and wireless HID devices benefit from the PIC18LF24K22T-I/SO's <100 nA sleep current, on-chip mTouch capacitive sensing for touch buttons, and EUSART for IR or RF transmission. The 28-SOIC wide package remains hand-solderable for low-volume production, and the 1.8V minimum supply allows direct drive from 2x AAA alkaline cells without boost regulators.
מומלץ
Portable Medical Monitoring Devices
Pulse oximeters, glucose meters, and wearable health monitors use the PIC18LF24K22T-I/SO for its deterministic 8-bit RISC core, low-noise ADC for biosignal acquisition, and ultra-low sleep mode between measurements. The wide 1.8V-3.6V supply range accommodates single Li-ion or 2x AA chemistries, while the 16 MIPS performance handles real-time filtering algorithms. Adequate validation per IEC 62304 is required before medical deployment.
מומלץ
Automotive Body and Comfort Electronics
Within automotive body controllers and comfort modules (seat controls, mirror adjusters, ambient lighting), the PIC18LF24K22T-I/SO handles LF and surge via integrated PWM outputs, comparators, and the robust SOIC-28 package. The -40 C to +85 C industrial temperature range is suitable for cabin environments. For under-hood AEC-Q100 qualified parts, the PIC18F25K22-I/SO or PIC18F46K22-I/P variants should be selected instead.
מומלץ
Smart Home and Building Automation
Smart thermostats, occupancy sensors, and HVAC controllers deploy the PIC18LF24K22T-I/SO for its low-power operation, ample I/O count (24 pins), and multiple communication interfaces including EUSART for Modbus and MSSP for SPI sensor buses. The 256 B EEPROM stores userconfig and last-state across power cycles, while ICSP enables field service updates. The 28-SOIC package simplifies UL-listed enclosure integration.

מבדילים עיקריים
- Lowest sleep current in PIC18 K22 SOIC-28 family (לעומתPIC18LF248T-I/SO)
- Higher MIPS performance in same SOIC-28 footprint (לעומתPIC18LF24J11T-I/SO)
- Same pinout, lower voltage variant (לעומתPIC18F24K22T-I/SO)
הערות תכנון
Estimated: at 3.3V VDD and 16 MIPS active current is approximately 4-6 mA typical, dropping to <100 nA in sleep mode. For a sensor node duty-cycled at 0.1% active duty cycle, average current is roughly 4-6 uA. Ensure decoupling capacitors (100 nF ceramic + 10 uF bulk) are placed within 5 mm of each VDD/VSS pin pair, and configure unused I/O as outputs low to avoid floating-input leakage in the nano-ampere range.
Keep the ICSP pins (RB6/PGC, RB7/PGD) accessible on the PCB with a 2x3 or 1x6 header for in-circuit debugging and programming. The MCLR/VPP pin (pin 28) requires a 10 kohm pull-up to VDD and a 100 nF cap to VSS for proper reset behavior; do not leave MCLR floating. Route analog signals (ANx, VREF+) away from digital switching traces to minimize ADC crosstalk; the SOIC-28 wide package keeps analog pins on one side for cleaner routing.
Do not exceed 3.6V VDD on the LF variant - use the F variant (PIC18F24K22T-I/SO) for 5V systems. The 28-pin SOIC package is wide-body (7.5 mm); do not confuse with the narrower 28-SOIC (3.81 mm body) used by some older PIC18F parts. When migrating from PIC18F24K22, ensure the configuration bits match - the LF variant has different low-voltage brown-out reset thresholds. Verify Flash endurance (100K cycles) before designing EEPROM emulation schemes that exceed this limit.
