• 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
• Modified Harvard Architecture Maximum Operating Speed: 16 MIPS @ 32 MHz 17 bit x 17 bit Single Cycle Hardware Fraction/Integer Multiplier 32 bit x 16 bit Hardware Divider 16 x 16 bit Work Register Array
• Encryption Engine Features
• NIST Standard Encryption/Decryption Operations without CPU Intervention AES Encryption Support for 128, 192, and 256 bit DES/3DES Encryption Support ECB, CBC, OFB, CTR, and CFB128 Modes Programmatically Secure Key Storage in OTP Arrays True Random Number Generation Battery Backup RAM Key Storage
• Dual Partition Flash Features
• Holds two separate software applications, including a boot loader Simultaneously with one partition of the program, Allows other partitions to run different application code Allows runtime switching between active partitions
• eXtreme Low Power Consumption (XLP) feature
• Multiple power management options Alternate clock mode for on-the-fly switching to low clock speed Very low current consumption during deep sleep: WDT 17 nA @ 2 V (typical), RTCC 17 nA @ 32 kHz 2 V (typical), deep sleep current, 16 nA (Typical value) Execution mode: 16 μA/MHz
