Overview

The PIC24FJ128GB202-I/MM is a 16-bit microcontroller featuring eXtreme Low Power (XLP) technology and integrated hardware encryption engines including AES, DES, and Triple DES. It provides 128KB of Flash memory and a dedicated USB On-The-Go (OTG) peripheral in a compact 28-pin QFN package. This device is specifically engineered for secure, battery-operated applications that require hardware-accelerated cryptography and USB connectivity.

Why Choose This Part

This MCU excels in security-critical designs by offloading cryptographic tasks to hardware engines, which reduces CPU overhead and power consumption compared to software libraries. It offers a wide operating voltage range from 2V to 3.6V and includes 5.5V tolerant digital inputs, providing flexibility when interfacing with legacy 5V logic.

Applications

Secure USB Dongles
Utilizes the built-in AES/DES hardware engines and USB OTG support to create encrypted data storage or security keys.
Battery-Powered IoT Sensors
Leverages XLP technology and Deep Sleep modes to extend battery life in remote sensing applications.
Portable Medical Devices
The 10-bit/12-bit ADC and low power profiles make it suitable for handheld diagnostic tools needing secure data handling.
Embedded Security Modules
Acts as a secure coprocessor for larger systems using its hardware True Random Number Generator (TRNG) and OTP key storage.

Getting Started

Begin development using the MPLAB X IDE and the XC16 compiler. For hardware evaluation, the Explorer 16/32 Development Board (DM240001-2) with a compatible Plug-In Module (PIM) is the standard platform. You will also need an in-circuit debugger such as the MPLAB ICD 4 or PICkit 4 for programming via the JTAG or ICSP interfaces.
