Microchip PIC24FJ256GB610-E/PT

PIC24FJ256GB610-E/PT 일반적인 설명

The eXtreme low power, PIC24F MCU includes up to 256KB of Flash memory with Error Correction Code (ECC) ,32 KB of RAM and USB connectivity. This device also features dual-partition Flash with Live Update capability, enabling them to hold two independent software applications, permitting simultaneous programming of one partition while executing application code from the other. With the ability to perform over-the-air firmware updates, designers can provide a cost-effective, reliable and secure method for updating their applications. These MCUs also feature eXtreme low power modes with current consumptions as low as 300nA in sleep modes.

This powerful combination of features makes the PIC24F “GA6” family ideal for industrial, computer, medical/fitness and portable applications that require a long battery life, and data transfer and storage without the need of external memory, such as electricity metering, HVAC control, fingerprint scanners and gaming.
