PIC24F 16-bit Microcontroller featuring integrated Hardware Crypto module and eXtreme Low Power. This family also includes 256KB Flash, 16KB RAM, USB, LCD and advanced peripherals. The combination of features makes the part ideally suited for low power embedded security applications.

Cryptographic Engine

• Performs NIST Standard Encryption/Decryption Operations without CPU Intervention
• AES Cipher Support for 128, 192 and 256-Bit Keys
• DES/3DES Cipher Support, with up to Three Unique Keys for 3DES
• Supports ECB, CBC, OFB, CTR and CFB128 modes
• Programmatically Secure OTP Array for Key Storage
• True Random Number Generation
• Battery-Backed RAM Key Storage

Extreme Low-Power

• Multiple Power Management Options for Extreme Power Reduction:

• VBAT allows for lowest power consumption on backup battery (with or without RTCC)
• Deep Sleep allows near total power-down with the ability to wake-up on external triggers
• Sleep and Idle modes selectively shut down peripherals and/or core for substantial power reduction and fast wake-up
• Doze mode allows CPU to run at a lower clock speed than peripherals

• Alternate Clock modes allow On-the-Fly Switching to a Lower Clock Speed for Selective Power Reduction
• Extreme Low-Power Current Consumption for Deep Sleep
  • WDT: 650 nA @ 2V typical
