Microchip PIC24F16KA102-I/SO: A Comprehensive Technical Overview
The Microchip PIC24F16KA102-I/SO represents a significant member of the PIC24F XLP family, engineered specifically for applications where ultra-low power consumption is the paramount design constraint. This 16-bit microcontroller (MCU) combines robust computational performance with exceptional energy efficiency, making it a premier choice for battery-powered and portable devices.
At its core, the device features a high-performance 16-bit modified RISC CPU capable of operating at up to 16 MIPS. This provides ample processing power for handling complex control algorithms, data processing, and user interface management without compromising on speed. A key architectural strength is its independent memory bus, which allows for concurrent program and data access, significantly enhancing operational efficiency.
Power management is where this MCU truly excels. It incorporates Microchip’s eXtreme Low Power (XLP) technology, enabling it to achieve some of the lowest power figures in the industry. The device boasts dramatically low current consumption across all active and sleep modes. Notably, its typical sleep currents can be as low as 20 nA, while its Real-Time Clock (RTC) and calendar function can operate for years on a single battery, drawing only 500 nA. This makes it ideal for applications that spend a majority of their lifetime in a standby state, waking only periodically to perform a task.
The peripheral set is meticulously curated for low-power applications. It includes multiple communication interfaces such as UART, SPI, and I2C™ modules, facilitating easy connectivity with sensors, wireless modules, and other system components. It also features a 10-bit Analog-to-Digital Converter (ADC) for acquiring real-world sensor data and multiple timers/counters for precise timing control.
The integrated Hardware Real-Time Clock and Calendar (RTCC) is a standout feature, providing accurate timekeeping even in the deepest sleep modes, which is crucial for data logging and time-based wake-up events. Furthermore, its extensive suite of power-managed modes allows developers to fine-tune the balance between performance and power consumption dynamically.
Housed in a 28-pin SOIC package, the `-I/SO` variant is specified for the industrial temperature range (-40°C to +85°C), ensuring reliable operation in harsh environments. Its compact form factor is suitable for space-constrained PCB designs.
ICGOODFIND: The PIC24F16KA102-I/SO is an exceptional 16-bit microcontroller that masterfully balances processing capability with groundbreaking ultra-low power consumption. Its integration of XLP technology, a versatile peripheral set, and a robust RTCC makes it an indispensable solution for developers of power-sensitive products like medical implants, remote sensors, smart meters, and personal wearable technology.
