Product details
Overview
MSP430F5500IRGZR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, comparator (no ADC), 8 KB flash, 4 KB + 2 KB RAM, four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), and RTC. It operates from 1.8 V to 3.6 V and targets battery-powered sensor interfaces and USB-connected data loggers.
For engineers reviewing the MSP430F5500IRGZR datasheet, MSP430F5500IRGZR pinout, MSP430F5500IRGZR application, or MSP430F5500IRGZR equivalent, key selection criteria include USB PHY integration, comparator-only analog front-end, 48-pin VQFN package, LPM4.5 shutdown current (0.18 µA), and port-mapped USCI signal routing on P4.
Technical Context
The MSP430F5500IRGZR implements a 16-bit RISC CPU with constant generators and unified clock system featuring FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes programmable LDO core regulation, SVS/SVM, and brownout detection.
USB functionality uses integrated USB-PHY, USB-PLL, and dual 3.3-V/1.8-V USB power system with eight endpoints. All USCI functions are routed through port mapping controller on P4, limiting simultaneous peripheral pinouts per configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5504IRGZR | Includes 10-bit ADC (6 external + 2 internal channels); same package, flash (8 KB), RAM, USB, timers, and USCI count | Required where analog signal digitization (e.g., voltage/current measurement) is needed alongside comparator functions | Select MSP430F5504IRGZR if ADC capability is essential; MSP430F5500IRGZR saves power and cost when only comparator-level decisions are required |
| MSP430F5501IRGZR | 16 KB flash, same RAM, USB, timers, USCI, and comparator; differs only in program memory size | Suitable for larger firmware images (e.g., USB HID + bootloader + sensor fusion algorithms) | Choose MSP430F5501IRGZR when firmware exceeds 8 KB; both share identical peripheral set and pinout |
Compared with MSP430F5504IRGZR and MSP430F5501IRGZR, the MSP430F5500IRGZR provides identical USB, timer, and USCI functionality at lowest static power and smallest flash footprint - ideal for comparator-triggered, event-driven USB peripherals with minimal code requirements.

FAQ
What is the primary differentiator of MSP430F5500IRGZR versus other MSP430F55xx devices?
The MSP430F5500IRGZR uniquely omits the 10-bit ADC present in MSP430F5504–F5510 variants and instead retains the full Comparator_B module. This makes it the lowest-power, most cost-effective option in the family for applications requiring only analog threshold detection - such as wake-on-event sensing or simple level monitoring - without digitization overhead. Its 8 KB flash and 48-pin VQFN package further optimize for compact, battery-operated USB peripherals.
Does MSP430F5500IRGZR support full-speed USB communication without external components?
Yes, MSP430F5500IRGZR integrates a full-speed USB 2.0 PHY, USB-PLL, and dual-rail USB power system (3.3 V and 1.8 V), enabling direct connection to a USB host with only passive termination (1.5 kΩ pull-up on D+ via PUR pin) and standard USB connectors. No external transceiver, level shifter, or oscillator is required, simplifying design and reducing BOM count.
How many USCI modules does MSP430F5500IRGZR include, and what interfaces do they support?
MSP430F5500IRGZR includes two USCI modules: USCI_A0 and USCI_B0. USCI_A0 supports UART (with automatic baud-rate detection), IrDA, and synchronous SPI. USCI_B0 supports I²C and synchronous SPI. Both modules are routed exclusively through port mapping controller on P4, allowing flexible pin assignment but requiring software configuration to avoid functional conflicts.
What low-power modes are available on MSP430F5500IRGZR, and what is the lowest achievable current draw?
MSP430F5500IRGZR supports six low-power modes (LPM0–LPM4.5). The deepest mode is LPM4.5 (shutdown), drawing just 0.18 µA at 3 V with full RAM retention and fast wake-up. LPM3 (standby with RTC) consumes 1.9 µA at 2.2 V. These modes are enabled via the power management module (PMM) and support ultra-long battery life in intermittent-sensing applications.
Is MSP430F5500IRGZR pin-compatible with other devices in the RGZ-48 package family?
Yes, MSP430F5500IRGZR shares identical 48-pin VQFN (RGZ) mechanical footprint and pinout with MSP430F5501IRGZR, MSP430F5502IRGZR, MSP430F5503IRGZR, MSP430F5504IRGZR, and MSP430F5505IRGZR. All use the same signal assignments per pin (e.g., P1.x, P4.x, DP/DM, RST/NMI), enabling hardware reuse across firmware variants - provided peripheral usage aligns with each device's internal feature set.
