Overview

The MSP430F5529IPNR is a 16-bit RISC-based microcontroller from Texas Instruments featuring an integrated USB 2.0 PHY and high-performance analog peripherals. It operates at up to 25MHz with 128KB of Flash and 10KB of RAM, optimized for portable applications requiring low power consumption and easy PC connectivity. The device includes a sophisticated power management system with multiple low-power modes, reaching shutdown currents as low as 0.18uA.

Why Choose This Part

The integrated USB physical layer (PHY) eliminates the need for external bridge ICs, reducing both BOM cost and board space in the 80-LQFP package. It offers a high balance of memory and I/O density, providing 63 GPIOs and 128KB of Flash for complex application firmware while maintaining the MSP430's industry-leading low-power performance profile.

Applications

USB Peripheral Devices
Ideal for battery-powered USB devices such as data loggers, HID interfaces, and portable medical monitors using the integrated USB 2.0 full-speed interface.
Portable Instrumentation
Utilizes the 12-bit ADC with 16 channels for high-resolution sensor data acquisition in hand-held testing equipment.
Industrial Sensors
Deploys in remote monitoring stations where the wide supply voltage range of 1.8V to 3.6V and ultra-low power standby modes prolong battery life.
Energy Harvesting Systems
Leverages extremely low shutdown and sleep currents to operate effectively from limited power budgets provided by solar or thermal harvesters.

Getting Started

Developers typically begin with the MSP-EXP430F5529LP LaunchPad development kit for rapid prototyping. Software development is supported by TI's Code Composer Studio (CCS) and the MSP430Ware software suite, which includes the USB Developer's Package to simplify USB stack implementation.

Also Consider

STM32L072CZT6 STMicroelectronics - A 32-bit Arm Cortex-M0+ alternative with USB support and comparable ultra-low power specifications.
MSP430FR5994 TITexas Instruments - Provides much larger 256KB of non-volatile FRAM and an integrated Low-Power Accelerator (LEA) for math-heavy applications.
