Microchip PIC24FJ256GL410-I/PT: A Comprehensive Technical Overview
The Microchip PIC24FJ256GL410-I/PT represents a high-performance, feature-rich member of the PIC24F "GL" family of 16-bit microcontrollers. Engineered for demanding embedded applications, this MCU combines robust processing power with a suite of advanced peripherals, making it a premier choice for complex designs in industrial control, medical devices, and consumer electronics.
At the heart of this device lies a powerful 16-bit modified Harvard architecture core, operating at up to 32 MIPS with a maximum frequency of 32 MHz. This provides a solid foundation for executing control algorithms and processing data with high efficiency. The core is augmented by a Direct Memory Access (DMA) controller, which supports eight channels and significantly reduces CPU overhead by handling data transfers between peripherals and memory autonomously, thereby boosting overall system performance.
A standout feature of this microcontroller is its substantial and versatile memory configuration. It is equipped with 256 KB of self-programmable Flash memory and 16 KB of RAM. This generous memory space is essential for storing large application code and managing complex data structures, which is critical for sophisticated applications requiring over-the-air (OTA) updates or extensive data logging.
The peripheral set integrated into the PIC24FJ256GL410-I/PT is exceptionally comprehensive, designed to interface with a vast array of sensors, actuators, and communication networks. Key peripherals include:
High-Speed Connectivity: It features multiple serial communication interfaces, including USB 2.0 (Full-Speed On-The-Go) for direct host or device connection, a CAN 2.0b module for robust industrial network communication, and multiple UART, SPI, and I²C™ modules for connecting to other peripherals.
Analog Capabilities: The MCU includes a sophisticated 12-bit Analog-to-Digital Converter (ADC) with up to 24 channels and a sampling rate of 500 ksps, ensuring precise measurement of analog signals. It also boasts dual 8-channel 16-bit sigma-delta Analog-to-Digital Converters (SDADC) for high-resolution audio or sensor applications and three operational amplifiers (Op Amps), reducing external component count.
Control and Timing: For motor control and power conversion applications, it offers a flexible 16-channel PWM module and five 16-bit timers/counters.
Housed in a 100-pin TQFP package, the device offers a high number of I/O pins while maintaining a relatively compact form factor. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environments.
ICGOODFIND: The Microchip PIC24FJ256GL410-I/PT is a highly integrated and powerful 16-bit microcontroller. Its compelling combination of a high-performance CPU, extensive memory, and a unparalleled suite of peripherals—including USB, CAN, and advanced analog—makes it an exceptional solution for complex embedded systems that require robust connectivity, precise data acquisition, and real-time control.
