The PIC24FJ128GA202T-I/SS microcontroller belongs to a family of Flash-based, 16-bit and 32-bit, embedded microcontrollers designed for use in a range of embedded application fields.

Application Field

The PIC24FJ128GA202T-I/SS is focused towards the industrial, automotive and consumer sectors due to its 16-bit architecture and low power performance. As such, this microcontroller is suited for applications such as industrial automation, medical monitoring systems, automotive engine control, home automation and consumer electronics. The range of onboard peripherals also lends itself to applications such as motor control and energy-sensitive low power applications such as energy harvesting systems.

Onboard Peripherals

The PIC24FJ128GA202T-I/SS features two high speed digital signal processors (DSPs) with integrated instructions and on chip memory management, which work together to enable the processing of multiple simultaneous, low power digital signal processing tasks. This microcontroller also features a range of built in peripherals to provide a complete embedded solution. These onboard peripherals include:

• RS-485 port, two CAN ports, two UARTs and one SPI port
• 12-bit Analogue to Digital Converter (ADC)
• 4-bit Pulse Width Modulator (PWM)
• On-chip Buck DC and Linear Regulator
• External and Internal Clock source
• Comprehensive I/O system

Working Principle

The PIC24FJ128GA202T-I/SS is operated by a 32-bit RISC (Reduced Instruction Set Computing) core that operates at a maximum frequency of 32 MHz. The microcontroller features enhanced Flash memory with an extensive range of features including self-programming, read/write and erase multiple pages, table read and self-unlock capability. All 16-bit instructions and 32-bit instructions are handled by the high speed DSPs.

The PIC24FJ128GA202T-I/SS features a range of security features such as read-only protection, software write protect, program lock and data EEPROM protection. Internal oscillators provide reliable and accurate 24MHz, 32MHz and 48MHz clock sources. An on-chip RTC calendar function allows for the monitoring of elapsed time and wake up from power-saving sleep mode.

By adhering to certain design rules, the PIC24FJ128GA202T-I/SS can achieve very low power consumption such as the usage of lower clock speeds and disabling of certain peripherals. The microcontroller is also programmable in assembly, C or C++, making it suitable for various development requirements.
