Devices in Microchip’s new PIC24F “GB2” family are the first PIC MCUs to offer an integrated hardware crypto engine along with eXtreme low power (XLP) performance. This new family also features a True Random Number Generator (RNG) and One-Time- Programmable (OTP) key storage for protecting data in embedded applications. For connectivity, the “GB2” family integrates USB for device or host connections as well as a UART with ISO7816 support, which is helpful for smart card applications. Key Features Cryptographic Engine ■ AES engine with 128, 192 or 256-bit key ■ DES/Triple DES (TDES) engine ■ True Random Number Generator (RNG) ■ The one-time-programmable (OTP) memory includes 512 bits for secure key storage eXtreme Low Power Features ■ 18 nA sleep, 180 μA/MHz Run ■ Enables integrity of data without sacrifi cing power consumption ■ VBAT allows the device to transition to a backup battery Connection to USB or Wireless Protocols ■ Integrated USB 2.0 device, host, OTG ■ Easy connection to certifi ed modules for Wi-Fi, ZigBee, Sub-GHz and Bluetooth Low Energy PIC24FJ128GB204 Family 16-bit ALU PIC24F 16 MIPS Barrel Shifter Address Generation 16x16 Register JTAG & EMU 17x17 MPY MEMORY BUS 28-pin: SSOP, SOIC, SPDIP, QFN 44-pin: TQFP, QFN PERIPHERAL BUS Peripheral Pin Select (PPS) Hardware Crypto Engine - AES, DES, 3DES 512 bits OTP Key Storage Random Number Generator USB 2.0 I2C™ - 2 SPI w/DMA / I2S - 3 UART - ISO 7816 Compatible w/LIN - 4 Input Compare - 6 Output Compare - 6 16-bit Timers - 5 Charge Time Meas.
