• PIC24FJxxxGA/GB406/410/412 16 bit Flash Microcontroller
• The Microchip PIC24FJxxxGA/GB406/410/412 family of microcontrollers is a 16 bit device with a wide variety of peripherals, suitable for applications requiring secure data transfer and storage.　Features include an on-board encryption engine, eXtreme Low Power (XLP) capability, and LCD display controller USB On-The-Go.　Dual-partition flash with live updates is of particular interest. This allows the MCU to maintain two separate software applications (including the boot loader).　In addition, this feature allows you to program one partition while running other application code on other partitions.
• CPU Features
