Product details
Overview
MSP430F5504IPTR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 8 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), single USCI (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA-designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5504IPTR datasheet, MSP430F5504IPTR pinout, MSP430F5504IPTR application, or MSP430F5504IPTR equivalent, key selection criteria include USB 2.0 compliance, LPM4.5 shutdown current (0.18 µA), 31 I/O pins in 48-pin LQFP, real-time clock with alarm, and single-USCI peripheral configuration versus higher-pin-count family members.
Technical Context
The MSP430F5504IPTR implements a unified clock system with FLL stabilization, programmable LDO core regulation, and dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz). Its power management includes five low-power modes (LPM0–LPM4.5) with sub-2 µA standby (LPM3) and <5 µs wake-up latency.
Peripherals are mapped via port mapping controller on P4; USB functionality requires dedicated DP/DM/PUR pins and internal USB-LDO/USB-PLL. The device uses the MSP430Xv2 CPU core with constant generators and supports serial bootloader (BSL) without external programming voltage.
Key Specifications

|---|---|
| Core Architecture | 16-bit RISC CPU (MSP430Xv2) with 16-bit registers and constant generators for optimized code density |
| Flash / RAM | 8 KB flash (in-system programmable) + 4 KB main RAM + 2 KB USB SRAM (usable as general-purpose when USB idle) |
| USB Interface | Full-speed USB 2.0 compliant with integrated PHY, 3.3-V/1.8-V USB power system, and 8 IN/8 OUT endpoints |
| ADC | 10-bit SAR ADC with 200 ksps sampling rate, window comparator, and 6 external + 2 internal input channels |
| Timers | Four 16-bit timers: TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC shadow registers) for PWM, capture, and interval timing |
| Low-Power Modes | LPM4.5 draws 0.18 µA at 3 V; LPM3 (RTC active) draws 1.9 µA at 2.2 V - enables multi-year coin-cell operation |

Applications
| USB-Powered Sensor Node | Portable Data Logger |
|---|---|
Use Scenario: Battery-operated environmental monitor that connects directly to PC or USB host for firmware updates and data retrieval. IC Role / Device Role / Timing Role: Primary MCU managing analog sensor acquisition (via ADC), USB communication, RTC-based sampling intervals, and low-power state transitions. Use Value: Integrated USB PHY and LPM4.5 current (0.18 µA) eliminate external transceiver and extend battery life beyond 5 years on CR2032. | Use Scenario: Handheld industrial logger capturing temperature, humidity, and voltage readings at user-defined intervals, then uploading via USB cable. IC Role / Device Role / Timing Role: Central controller executing timed ADC conversions, storing results in RAM/flash, maintaining timestamp via RTC, and handling bulk USB data transfer. Use Value: Hardware DMA offloads USB/ADC transfers from CPU, enabling continuous background logging while CPU remains in LPM3 (1.9 µA). |
| Wireless Headset Bridge | Low-Power USB HID Device |
Use Scenario: Adapter converting Bluetooth audio stream to USB audio class (UAC) for legacy PCs lacking BT support. IC Role / Device Role / Timing Role: USB device controller interfacing with BT SoC over UART, buffering audio packets, and presenting as USB audio endpoint. Use Value: Single USCI handles UART comms with BT module; full-speed USB ensures 48 kHz stereo streaming without packet loss. | Use Scenario: Programmable USB keyboard or presentation remote requiring secure firmware updates and long battery runtime. IC Role / Device Role / Timing Role: USB HID device implementing custom report descriptors, button debouncing, and low-power suspend/resume. Use Value: LPM3 (1.9 µA) and fast wake-up (<5 µs) enable instant response after USB suspend - critical for human-interface responsiveness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5505IRGZR | VQFN-48 package (7×7 mm), same 8 KB flash, identical peripheral set except no P3.x USCI pins - all USCI routed via P4 port mapping | Requires different PCB layout due to QFN footprint and absence of dedicated USCI pins; better thermal performance | Select for space-constrained designs needing improved thermal dissipation and where P4 remapping suffices for serial interface needs |
| MSP430F5506IPTR | 24 KB flash (vs. 8 KB), same LQFP-48 package, identical peripherals and pinout - direct drop-in replacement with more program memory | Enables larger firmware (e.g., USB CDC + OTA update stack) without changing board layout or firmware initialization | Select when additional flash is required for feature-rich USB device firmware while retaining identical hardware design |
Compared with MSP430F5505IRGZR, the MSP430F5504IPTR offers identical functionality in LQFP-48 but with fixed P3.x USCI pins - simplifying layout for UART/I²C; versus MSP430F5506IPTR, it trades flash capacity for cost-sensitive applications where 8 KB suffices.

FAQ
What is the maximum system clock frequency supported by the MSP430F5504IPTR?
The MSP430F5504IPTR supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the integrated FLL with XT2 crystal (up to 32 MHz) or internal DCO. This allows high-speed execution while maintaining ultra-low power consumption in active mode (195 µA/MHz at 8 MHz, 3 V).
Does the MSP430F5504IPTR support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5504IPTR supports dual crystal oscillators: XT1 accepts 32-kHz watch crystals for RTC operation, and XT2 supports high-frequency crystals up to 32 MHz for system clocking. Both are independently configurable and can run simultaneously for optimal timing flexibility.
How many USB endpoints does the MSP430F5504IPTR provide, and what types are supported?
The MSP430F5504IPTR provides eight input and eight output USB endpoints, supporting standard USB 2.0 full-speed device functionality including control, interrupt, bulk, and isochronous transfers - sufficient for complex USB device classes like CDC, HID, or MSC.
Can the MSP430F5504IPTR operate from a single 3.3-V supply, and how is USB power managed?
Yes, the MSP430F5504IPTR operates from a single 3.3-V supply. Its integrated USB power system generates regulated 1.8-V core power for the USB PHY and 3.3-V I/O power from the main supply - eliminating need for external USB LDOs and simplifying power design.
What debug interface does the MSP430F5504IPTR use, and is external hardware required?
The MSP430F5504IPTR uses the 2-wire Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO pin, compatible with TI's MSP-FET and standard JTAG adapters. No external level-shifting or additional hardware is required - enabling compact, low-cost development and production programming.
