Microchip PIC24F04KA200-I/ST: A Comprehensive Technical Overview

The Microchip PIC24F04KA200-I/ST represents a key component in the expansive PIC24F family of 16-bit microcontrollers. Engineered for applications demanding a balance of processing power, energy efficiency, and peripheral integration within a compact form factor, this MCU is a versatile solution for embedded designers. This overview delves into its core architecture, key features, and target applications.

At the heart of this device lies a high-performance 16-bit Modified RISC CPU core. This architecture is designed for efficient C code execution, offering a 24-bit instruction word with a 16-bit data path. It operates at a maximum frequency of 16 MIPS (16 MHz), providing a substantial performance uplift over traditional 8-bit MCUs while maintaining deterministic interrupt response. A cornerstone of its design is its exceptional low-power management. Featuring multiple software-selectable power modes, including Deep Sleep (nA range) and a low-current Real-Time Clock (RTC) mode, the device is ideally suited for battery-powered and energy-harvesting applications where extending operational life is paramount.

The integration of peripherals is a significant strength. The 'KA200' variant is particularly noted for its integrated mTouch capacitive sensing hardware, simplifying the design of touch interfaces without external components. Communication is facilitated by a suite of serial channels, including UART, SPI, and I²C modules, ensuring connectivity with a vast array of sensors, displays, and other ICs. Furthermore, it boasts a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels, enabling precise acquisition of analog sensor data.

The specific part number, PIC24F04KA200-I/ST, provides detailed information: It contains 4 KB of Flash program memory and 256 Bytes of RAM. The '-I' suffix denotes an industrial temperature range (-40°C to +85°C), making it robust for demanding environments. The package is a 14-pin TSSOP (ST), which offers a compact footprint for space-constrained PCB designs.

Typical applications leverage its combination of low power and integrated features. It is an excellent choice for consumer electronics (remote controls, touch panels), portable medical devices, industrial sensing nodes, and sophisticated automotive accessories.
