PIC18F24K22-I/MV - 16KB Flash 8-bit MCU, 28-Pin UQFN | Microchip
The Microchip Technology PIC18F24K22-I/MV is an 8-bit PIC18 RISC microcontroller with 16KB of Flash program memory, 768 bytes of SRAM, and 256 bytes of EEPROM, housed in a 28-pin UQFN EP (4x4 mm) package with exposed thermal pad. It operates at up to 40 MHz (64 MHz with PLL) from a 2.5V/3.3V/5V supply range and carries AEC-Q100 automotive-grade qualification. According to the Microchip PIC18(L)F2X/4XK22 datasheet, the device integrates nanoWatt XLP technology that drops idle consumption into the low-30 nA region, enabling multi-year battery life on a single cell.
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.
