PIC18LF24K22-I/MV - 8-bit XLP MCU 16KB Flash 28-UQFN | Microchip
MPN: PIC18LF24K22-I/MV ✓ פעילPIC18LF24K22-I/MV סקירה
A microcontroller (MCU) is a single-chip computer containing a CPU, program memory (Flash), data memory (RAM), and programmable peripherals. The PIC18 family sits in Microchip's 8-bit hierarchy: PIC10/12/16/18 -> 8-bit MCU -> microcontroller -> embedded computing IC -> semiconductor. The 'LF' subfamily specifically targets ultra-low-power applications through nanoWatt XLP technology, enabling sleep currents in the nanoamp range.
Key features include 16KB Flash self-programmable memory, 256 bytes of EEPROM, 10-bit ADC up to 17 channels, multiple PWM modules, EUSART, MSSP (SPI/I2C), and ultra-low-power sleep modes. The integrated 16MHz internal oscillator eliminates external crystals in many designs, while the 28-pin UQFN package provides compact 4x4 mm footprint with exposed thermal pad suitable for space-constrained applications. CIP (Core Independent Peripherals) reduce CPU overhead by handling tasks autonomously in hardware.
The PIC18LF24K22 architecture uses an enhanced Harvard RISC core with 49 instructions and hardware multiplier, executing most instructions in a single cycle for predictable deterministic performance. CIP features like CLC, PPS, and NCO enable complex signal routing without CPU intervention, making it suitable for real-time sensor processing and motor control loops.
Typical applications include low-power IoT sensor nodes, battery-powered medical devices, industrial control modules, consumer electronics HMI, USB peripherals, and automotive body electronics. The wide peripheral set and low-power modes also suit remote controls, smart metering, and wearable health monitoring. The industrial -40C to +85C temperature range supports harsh environment deployment.
When designing with this device, configure the PPS (Peripheral Pin Select) module early to avoid pin conflicts. Use the internal 16MHz HFINTOSC to save BOM cost and board space, but verify timing margins against your application. Review the PIC18(L)F24K22 datasheet for current consumption tables under different clock and sleep configurations before finalizing power budgets.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone. The 28-UQFN (4x4) footprint is shared with the standard PIC18F24K22-I/MV and the tape-and-reel variant PIC18LF24K22T-I/MV, enabling layout reuse across the LF/F families.

הערות תכנון
Estimated: at 3.3V VDD with CPU active at 64MHz, core current is approximately 8-12 mA per Microchip datasheet typical curves; at 16MHz HFINTOSC this drops to ~2 mA. Sleep current with RTC enabled is ~1 uA, and deep sleep (all off) is below 100 nA. Use the internal HFINTOSC and disable unused peripherals in firmware to maximize battery life.
The 28-UQFN package has an exposed thermal pad that must be soldered to a copper pad on the PCB for thermal and mechanical reliability. Per Microchip package specification, the EP pad should connect to a ground plane with at least 4 thermal vias (0.3 mm diameter) for heat dissipation. Place decoupling 100nF + 10uF capacitors as close as possible to VDD pin 26 and VSS pin 8.
Configure PPS (Peripheral Pin Select) early in firmware to avoid pin conflicts: many peripherals are remappable to multiple pins. Per datasheet, the RPx pins must be unlocked via IOLOCK before reconfiguration, and unlocking requires a specific unlock sequence in software. Failure to do so leaves peripherals on default pins and wastes board space.
For high-speed SPI/I2C communication beyond 1 MHz, place 4.7k-10k pull-ups on I2C lines and use series resistors (22-33 ohm) on SPI clock/data traces. Per Microchip MSSP section, MSSP timing margins shrink above 8 MHz; verify signal integrity with an oscilloscope and respect the 4x VDD trace width rule.
