Microchip PIC18F24K40-I/SO 8-Bit Microcontroller Datasheet and Technical Specifications

The Microchip PIC18F24K40-I/SO is a powerful member of the enhanced mid-range PIC18 “K40” family of 8-bit microcontrollers (MCUs). It is engineered to deliver a compelling blend of core performance, advanced peripherals, and nanoWatt XLP ultra-low-power technology, making it an ideal solution for a wide array of embedded control applications in the automotive, industrial, consumer, and IoT markets.

Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this MCU is designed for space-constrained applications requiring surface-mount technology. Its core operates at up to 64 MHz, achieving 16 MIPS (Million Instructions Per Second), and is built upon a robust foundation with enhanced instruction set and hardware features.

Key Technical Specifications and Features:

Core and Memory: The device is built around an enhanced PIC18 core with a 16-level deep hardware stack and an orthogonal instruction set for improved C compiler efficiency. It features 16 KB of Flash program memory, 1024 bytes of Data SRAM, and 256 bytes of Data EEPROM for non-volatile data storage.

Analog Capabilities: A standout feature is its advanced analog peripheral set. It includes a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2). This innovative module can perform math operations (averaging, filtering, threshold comparison) autonomously while the CPU is in sleep mode, drastically reducing power consumption in sensor applications. It also incorporates 5-bit DACs and two comparators.

Connectivity and Communication: The PIC18F24K40 offers a rich set of serial communication interfaces, including EUSART (UART), I2C, and SPI modules. These provide flexible options for connecting to sensors, memory, other microcontrollers, or a PC.

Timing and Control: It is equipped with multiple timers, including four 8-bit timers and three 16-bit timers. A key feature is the Hardware Limit Timer (HLT), which provides a failsafe mechanism for controlling PWM outputs, crucial for motor control and digital power conversion applications.

Ultra-Low Power Performance: True to its nanoWatt XLP designation, this MCU excels in power-sensitive designs. It boasts deep sleep currents as low as 20 nA and features peripheral module disable (PMD) circuitry to shut down unused peripherals, minimizing power consumption.

Operating Characteristics: The device operates over an extensive voltage range of 1.8V to 5.5V and a temperature range of -40°C to +85°C, ensuring reliability in harsh environmental conditions.

ICGOODFIND: The Microchip PIC18F24K40-I/SO is a highly integrated and versatile 8-bit microcontroller. Its combination of a high-performance core, advanced autonomous analog peripherals like the ADC2, extensive communication interfaces, and industry-leading ultra-low-power capabilities makes it a superior choice for designers developing efficient, responsive, and connected embedded systems.
