PIC18F24K22-I/MV Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, a RISC or CISC CPU core, on-chip program memory (Flash or ROM), data memory (SRAM), non-volatile EEPROM, and a rich set of peripherals such as ADC, timers, and communication ports. The PIC18 family uses an enhanced Harvard RISC architecture that separates program and data buses, allowing simultaneous fetch and execute to deliver high MIPS-per-mW efficiency. Within the broader taxonomy, PIC18F24K22 belongs to the Microchip 8-bit microcontroller family (PIC10, PIC12, PIC16, PIC18), then to the microcontrollers (MCUs) category, then to integrated circuits, and finally to semiconductors.
Key features include 25 digital I/O pins, a 10-bit ADC with up to 17 channels, two Enhanced USART modules, two MSSP (SPI/I2C) ports, three 16-bit timers, four 8-bit timers, an Enhanced Capture/Compare/PWM module, and a Charge Time Measurement Unit (CTMU) for capacitive touch. The device integrates an internal 16 MHz oscillator and supports up to 64 MHz via the on-chip PLL. Self-programming under software control enables in-field firmware updates without an external programmer.
The PIC18F24K22-I/MV uses CMOS Flash process technology with nanoWatt XLP idle and sleep modes that drop current to as low as 20 nA in sleep with RTCC and 100 nA with the watchdog timer running. The AEC-Q100 qualification extends this same low-power performance into automotive environments, making the part suitable for body, interior, and chassis electronics that must operate reliably across -40C to +125C.
Typical applications include automotive body and interior modules, low-power sensor nodes, portable medical instruments, IoT edge devices, consumer white goods, and battery-backed industrial controllers. The wide 1.8V-5.5V operating range (across the PIC18LF24K22 and PIC18F24K22 family) and abundant analog and digital peripherals let a single MCU handle both sensor acquisition and communication in compact designs. When migrating within the PIC18 (L)F2X/4XK22 family, designers should evaluate the I/O count (25), ADC channel count, and supply range; the 28-pin UQFN EP variant is the most space-constrained, while 40-pin and 44-pin variants add peripherals without changing the CPU architecture. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the bare Microchip datasheet, giving engineers a single-page technical reference for the PIC18F24K22-I/MV.

Aplicaciones típicas
PIC18F24K22-I/MV es adecuado para 6 aplicacións: Automotive Body Control Module, Low-Power IoT Sensor Node, Portable Medical Instrument, Battery-backed Industrial Controller, Consumer White Goods Control, Capacitive Touch User Interface.
Automotive Body Control Module
The PIC18F24K22-I/MV's AEC-Q100 qualification and 25 I/O pins make it well suited for automotive body control modules that must operate reliably across -40C to +85C. The MCU's 16KB Flash supports CAN/LIN gateway firmware via the two Enhanced USART modules and PWM-driven load drivers through its three 16-bit timers and Enhanced CCP module. nanoWatt XLP sleep current in the low-30 nA region lets BCM subsystems shut down quiescent loads to <100 uA when the vehicle is parked, preserving battery life over weeks of inactivity. The 28-pin UQFN EP package's 4x4 mm footprint integrates easily into space-constrained door, seat, and lighting modules.
Recomendado
Low-Power IoT Sensor Node
The PIC18F24K22-I/MV's nanoWatt XLP technology enables IoT sensor nodes that run for years on a single CR2032 coin cell. Sleep current as low as 20 nA with RTCC active lets the MCU wake periodically to read sensors via its 10-bit ADC with up to 17 channels, then transmit over UART or SPI to a low-power radio. The 16KB Flash comfortably holds Contiki-style lightweight stacks or custom sensor-fusion firmware. Two MSSP ports (SPI/I2C) accommodate simultaneous sensor and radio connectivity, while the CTMU simplifies touch or capacitive-level sensing without external components.
Recomendado
Portable Medical Instrument
The PIC18F24K22-I/MV fits portable medical instruments that demand long battery life and reliable ADC performance. The 10-bit ADC with up to 17 channels acquires signals from pulse-oximetry, blood-pressure, or temperature probes with sufficient resolution for many clinical-grade readings. nanoWatt XLP sleep modes drop consumption below 100 nA between measurements, extending battery life to months. The AEC-Q100 automotive-grade silicon screening translates to high reliability even though the part is used in a medical (non-automotive) application. The 28-pin UQFN EP's 4x4 mm footprint supports miniaturized form factors.
Recomendado
Battery-backed Industrial Controller
The PIC18F24K22-I/MV's wide 1.8V-5.5V family operating range and 256 bytes of EEPROM make it well suited for battery-backed industrial controllers that retain calibration and configuration data across power cycles. The two Enhanced USARTs support RS-232/RS-485 communication with industrial sensors and PLCs, while the 10-bit ADC reads 4-20 mA process signals through external scaling resistors. nanoWatt XLP sleep with the watchdog timer enabled draws roughly 100 nA, enabling RTC-driven wake from a backup supercapacitor or coin cell. The -40C to +85C industrial temperature range covers most factory-floor installations.
Recomendado
Consumer White Goods Control
The PIC18F24K22-I/MV powers control boards in washing machines, dishwashers, refrigerators, and other consumer white goods where cost-effective 8-bit processing is sufficient. Three 16-bit timers and the Enhanced CCP module drive triac-controlled motor phases and heater PWM, and the 25 I/O pins connect to keypads, displays, and door sensors. The 28-pin UQFN EP package supports slim-line appliance form factors. nanoWatt XLP standby modes cut idle consumption to <1 uA, helping appliances meet Energy Star standby budgets without complex external power switching.
Recomendado
Capacitive Touch User Interface
The PIC18F24K22-I/MV's integrated Charge Time Measurement Unit (CTMU) provides a hardware mechanism for capacitive touch sensing without external components or dedicated touch ICs. Combined with the 25 I/O pins, the MCU supports up to 12-16 touch buttons plus slider/wheel gestures on a single chip, ideal for appliance front panels and IoT devices. The nanoWatt XLP technology keeps the touch-scanning standby current below 100 nA, so a battery-powered remote can sit idle for years. The 28-pin UQFN EP package is small enough for handheld remote-control form factors.

Diferenciadores clave

- Seamless upgrade path to 32KB and 64KB Flash in same package (frente a PIC18F25K22-I/MV and PIC18F26K22-I/MV)

Notas de diseño
Take advantage of nanoWatt XLP sleep modes by configuring the MCU to enter Sleep between ADC samples, sensor reads, or communication bursts. With RTCC active, sleep current is as low as 20 nA; with the watchdog timer active, sleep current is approximately 100 nA. For battery-powered designs, disable all unused peripherals (USART, MSSP, ADC, timers) before entering Sleep to minimize leakage. The PIC18F24K22-I/MV's ULPWU (Ultra-Low-Power Wake-Up) module on RA0 can wake the MCU from an analog signal threshold without an external comparator.
The 28-pin UQFN EP package's exposed thermal pad must be soldered to a sufficiently large ground plane on the PCB for thermal dissipation and electrical performance. While PIC18F24K22-I/MV's active current is typically 5-10 mA at full CPU speed, the UQFN package's small thermal mass relies on the PCB copper pour to limit junction temperature rise. Recommended layout: at least one square centimeter of copper on the top layer connected to the EP, plus thermal vias to the ground plane. For continuous high-speed operation at +85C ambient, monitor VDD and ambient temperature closely.
Place the VDD decoupling capacitor (100 nF ceramic, X7R) as close as possible to pin 6, with an additional bulk capacitor (1-10 uF) within 5 mm. Place a second 100 nF decoupling cap near pin 28 (VSS) to provide a low-impedance return path. The MCLR pin (pin 24) should be pulled up to VDD through a 10 kohm resistor, with a 100 nF cap to VDD for noise immunity. Keep the ICSP clock (PGC, pin 14) and data (PGD, pin 15) traces short and away from high-frequency switching nodes to avoid in-circuit debug issues.
A common mistake is using a 3.3V supply with the PIC18F24K22-I/MV when the application needs 5V tolerance on digital inputs; the LF variant PIC18LF24K22-I/MV is the correct choice for 1.8V-3.6V systems only. Another pitfall is failing to configure unused I/O pins as outputs with defined low state to minimize supply current. Finally, ensure that the CONFIG words (oscillator selection, watchdog, brown-out voltage) match the system design before locking the part; misconfigured CONFIG words require a high-voltage ICSP erase sequence to recover.
