Texas Instruments' MSP430F5529 mixed-signal microcontroller (MCU) is part of the ultra-low-power MSP430 MCU family. This TI MCU is configured with integrated USB and PHY supporting USB 2.0, four 16-bit timers, a high-performance 12-bit ADC, and a real-time clock module with alarm capabilities. The TI MSP430F5529 has 63 I/O pins, compared to 47 I/O pins on the MSP430F5528.
Typical applications include analog and digital sensor systems, data loggers, and other applications requiring connectivity to various USB hosts.
