Product details
Overview
MSP430F5502IRGZT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with integrated USB 2.0 PHY, 24 KB flash, 4 KB + 2 KB RAM, comparator (no ADC), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes requiring USB connectivity and precise analog monitoring.
For engineers reviewing the MSP430F5502IRGZT datasheet, MSP430F5502IRGZT pinout, MSP430F5502IRGZT application, or MSP430F5502IRGZT equivalent, key selection criteria include its 48-pin VQFN package, comparator-based analog front-end (vs. ADC-equipped variants), USB-capable power architecture (integrated 3.3-V/1.8-V USB LDO and PLL), and low-power mode current of 1.1 µA in LPM4 at 3 V.
Technical Context
The MSP430F5502IRGZT implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and internal VLO/REFO sources. Its power management includes a programmable LDO core regulator, supply voltage supervision (SVM/SVS), and brownout reset - enabling robust operation across variable battery conditions.
Peripherals are mapped via port mapping controller on P4, limiting simultaneous USCI function availability; all I/O pins support Schmitt-trigger inputs and configurable drive strength. The device lacks ADC10_A but retains COMP_B with four channels, making it suitable for threshold-detection applications without digitization overhead.

FAQ
What is the maximum system clock frequency supported by the MSP430F5502IRGZT?
The MSP430F5502IRGZT supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL and high-frequency crystal oscillator (XT2) supporting up to 32 MHz input. This frequency meets full-speed USB 2.0 timing requirements while maintaining deterministic real-time execution for time-critical tasks.
Does the MSP430F5502IRGZT include an analog-to-digital converter (ADC)?
No, the MSP430F5502IRGZT does not include an ADC. Per the device comparison table and functional block diagram, it features COMP_B (a 4-channel comparator with window capability) instead of ADC10_A. This distinguishes it from variants like MSP430F5504IRGZT and MSP430F5506IRGZT, which integrate a 10-bit ADC.
What USB functionality does the MSP430F5502IRGZT provide?
The MSP430F5502IRGZT provides full-speed USB 2.0 connectivity with an integrated PHY, dedicated USB power system (3.3-V and 1.8-V LDOs), USB-PLL for clock synthesis, and eight configurable endpoints. It supports standard USB classes including CDC, HID, and MSC without external transceivers or voltage translators.
What package type and pin count does the MSP430F5502IRGZT use?
The MSP430F5502IRGZT uses a 48-pin VQFN package (RGZ variant), measuring 7 mm × 7 mm with 0.5-mm pitch and an exposed thermal pad. This package is confirmed in TI's SLAS645L datasheet Section 8 and matches the "RGZ" suffix in the part number.
How many USCI modules does the MSP430F5502IRGZT support, and what protocols do they implement?
The MSP430F5502IRGZT supports two USCI modules: USCI_A0/A1 (configurable for UART, IrDA, or SPI) and USCI_B0/B1 (configurable for I²C or SPI). Function pinout is dynamically assigned via the port mapping controller on P4, allowing flexible protocol allocation within hardware constraints.
