Microchip PIC24FJ128GA110-I/PT: A Comprehensive Technical Overview
The Microchip PIC24FJ128GA110-I/PT stands as a prominent member of the PIC24F family, representing a robust 16-bit architecture engineered for demanding embedded applications. This microcontroller unit (MCU) combines high computational performance with a rich set of peripherals, making it a versatile solution for complex designs in industrial control, medical devices, and advanced consumer electronics.
At its core, the device features a modified Harvard architecture 16-bit CPU capable of operating at up to 16 MIPS (16 Million Instructions Per Second). This performance is driven by a high-speed 32 MHz internal oscillator, ensuring efficient execution of control algorithms and data processing tasks. The inclusion of a DMA (Direct Memory Access) controller further enhances system efficiency by allowing data transfers between peripherals and memory to occur independently of the CPU, significantly reducing overhead and power consumption.
A key specification is its 128 KB of self-programmable Flash memory and 8 KB of RAM. This substantial memory space is essential for housing sophisticated application code and managing data in real-time operating systems (RTOS) or data-intensive tasks. The Flash memory offers exceptional flexibility with 1,000 erase/write cycle durability (typical), supporting robust field firmware updates.
The peripheral set integrated into this MCU is extensive and designed for connectivity and control. It includes:
Communication Interfaces: Multiple UART, SPI, and I²C™ modules facilitate seamless communication with a vast array of sensors, displays, and other ICs.
Analog Capabilities: A high-speed 10-bit Analog-to-Digital Converter (ADC) with a sampling rate of up to 500 ksps (kilo-samples per second) enables precise measurement of analog signals. Multiple comparators provide additional flexibility for real-time analog signal monitoring.
Timing and Control: Five 16-bit timers/counters, including a dedicated real-time clock and calendar (RTCC), offer precise timing generation, waveform capture, and comparison capabilities. This is crucial for motor control, power conversion, and event scheduling.
Hardware Features: The MCU supports up to 53 programmable I/O pins, offering extensive connectivity for external components. It also features a powerful PWM (Pulse Width Modulation) module, ideal for controlling motors, LEDs, and power supplies.
Housed in a 64-pin TQFP (Thin Quad Flat Pack) package, the PIC24FJ128GA110-I/PT provides a compact footprint while offering a high pin count for maximum peripheral connectivity. The "-I" suffix in its part number denotes an industrial temperature range of -40°C to +85°C, ensuring reliable operation in harsh environmental conditions. Its design emphasizes low power consumption, featuring multiple power-saving modes (Sleep, Idle, and Doze) to extend battery life in portable applications.
ICGOODFIND: The Microchip PIC24FJ128GA110-I/PT is a high-performance, feature-rich 16-bit microcontroller. Its combination of substantial memory, a high-speed core with DMA, an extensive suite of communication and analog peripherals, and robust industrial-grade packaging makes it an exceptional choice for developers tackling complex embedded systems that require reliable performance, connectivity, and real-time control.
