Product details
Overview
MSP430F5504IPT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated 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, and hardware multiplier - designed for battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5504IPT datasheet, MSP430F5504IPT pinout, MSP430F5504IPT application, or MSP430F5504IPT equivalent, key selection criteria include its LQFP-48 package, 31 I/O pins, USB-capable power architecture (integrated 3.3-V/1.8-V USB LDO and PLL), low-power modes down to 0.18 µA (LPM4.5), and compatibility with TI's MSP430F5xx toolchain and development ecosystem.
Technical Context
The MSP430F5504IPT implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), VLO and REFO internal sources, and programmable LDO core regulation. Its CPUXV2 core executes instructions at up to 25 MHz with constant generators for optimized code density.
Peripherals are mapped via port mapping controller (P4), enabling flexible USCI signal routing; USB functionality requires dedicated DP/DM/PUR pins and VBUS sensing, while ADC10_A supports window comparator mode and sampling rates up to 200 ksps. All low-power modes retain full RAM and support sub-5-µs wake-up.

FAQ
What is the maximum operating frequency of the MSP430F5504IPT?
The MSP430F5504IPT supports a maximum system clock frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL-based clock stabilization. This allows high-throughput execution of USB transactions and ADC conversions while maintaining deterministic timing for real-time tasks.
Does the MSP430F5504IPT support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5504IPT supports dual crystal configurations: a 32.768-kHz watch crystal on P5.4/P5.5 (XIN/XOUT) for RTC and ACLK, and a high-frequency crystal up to 32 MHz on P5.2/P5.3 (XT2IN/XT2OUT) for MCLK and SMCLK generation - both fully integrated into the unified clock system.
How many USB endpoints does the MSP430F5504IPT provide, and what types are supported?
The MSP430F5504IPT provides eight IN endpoints and eight OUT endpoints, supporting standard USB 2.0 full-speed device operation. It natively implements control, interrupt, bulk, and isochronous transfer types through its USB module, enabling robust HID, CDC, and custom class implementations without external USB controller ICs.
Can the MSP430F5504IPT operate from a single USB VBUS supply?
Yes - the MSP430F5504IPT integrates a USB power system with dedicated VUSB (3.3 V) and V18 (1.8 V) LDO outputs, allowing direct operation from USB VBUS (4.4–5.25 V). The internal regulators power the USB PHY, PLL, and core logic, eliminating need for external DC-DC converters in bus-powered designs.
What is the ADC resolution and input channel count for the MSP430F5504IPT?
The MSP430F5504IPT features a 10-bit successive approximation register (SAR) ADC (ADC10_A) with six external analog input channels (P6.0–P6.3, P5.0–P5.1) and two internal sources (VeREF+, VeREF−), supporting up to 200 ksps sampling rate and window comparator functionality for autonomous threshold detection.
