Microchip PIC24FJ64GA002-I/ML 16-bit Microcontroller Overview and Application Guide
The Microchip PIC24FJ64GA002-I/ML represents a powerful and versatile member of the PIC24F family of 16-bit microcontrollers (MCUs). Engineered for applications demanding a balance of high computational performance, low power consumption, and a rich set of integrated peripherals, this MCU is a cornerstone for developers in the industrial, medical, and consumer electronics sectors. Housed in a compact 28-pin QFN (ML) package, it is designed for space-constrained designs without compromising on functionality.
Core Architecture and Performance
At the heart of this microcontroller lies a modified Harvard architecture 16-bit CPU core, capable of operating at up to 16 MIPS (Million Instructions Per Second) with a maximum clock frequency of 32 MHz. This performance level ensures efficient handling of complex control algorithms and data processing tasks. A key feature enhancing its real-time response is the integrated DMA (Direct Memory Access) controller, which allows data to be transferred between peripherals and memory without CPU intervention, significantly reducing overhead and improving system efficiency.
Memory and Integration
The device boasts 64 KB of self-programmable Flash memory and 8 KB of RAM, providing ample space for application code and data handling. Its high level of integration is a major advantage, incorporating a 10-bit Analog-to-Digital Converter (ADC) with a sampling rate of up to 500 ksps, multiple communication interfaces including UART, SPI, and I²C modules, and multiple 16-bit timers/counters. This rich peripheral set reduces the need for external components, lowering overall system cost and complexity.
Low-Power Management
A standout feature of the PIC24FJ64GA series is its exceptional power management capabilities. It features multiple programmable power-saving modes, including Sleep, Idle, and Doze modes. In Sleep mode, the core clock is halted while peripherals can remain active, drawing minimal current. This makes it exceptionally suited for battery-powered and portable applications where extending operational life is critical.
