Product details
Overview
MSP430F5504IRGZR 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 MSP430F5504IRGZR datasheet, MSP430F5504IRGZR pinout, MSP430F5504IRGZR application, or MSP430F5504IRGZR equivalent, key selection criteria include USB 2.0 compliance, LPM4.5 shutdown current (0.18 µA), 31 I/O pins in 48-pin VQFN, and compatibility with TI's MSP430Ware and Code Composer Studio toolchain.
Technical Context
The MSP430F5504IRGZR implements a digitally controlled oscillator (DCO) with FLL stabilization, supports dual crystal sources (XT1 at 32 kHz, XT2 up to 32 MHz), and integrates a programmable LDO core regulator. Its unified clock system enables dynamic voltage scaling and sub-5 µs wake-up from LPM3 standby mode.
USB functionality is implemented via an on-die PHY, dedicated USB-PLL, and dual 3.3-V/1.8-V power rails - eliminating external transceivers. The single USCI module is configurable via port mapping controller on P4, supporting UART, SPI, or I²C depending on runtime configuration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5504IPTR | Same silicon, 48-pin LQFP package (7 mm × 7 mm) with through-hole mounting and larger pitch (0.5 mm vs. 0.4 mm). | LQFP eases prototyping and manual rework but increases board area and thermal resistance vs. VQFN. | Select MSP430F5504IPTR for breadboard evaluation or low-volume assembly where solder-reflow capability is limited. |
| MSP430F5505IRGZR | Identical package and pinout, but with 16 KB flash (vs. 8 KB) and same 4 KB + 2 KB RAM - no change to USB, ADC, or timer resources. | Supports larger firmware images (e.g., USB HID + custom class + bootloader) without requiring layout change. | Choose MSP430F5505IRGZR when future firmware expansion or dual-application partitioning is anticipated. |
Compared with MSP430F5504IPTR and MSP430F5505IRGZR, the MSP430F5504IRGZR offers optimal cost and size for fixed-function USB sensor nodes where flash headroom and package form factor are tightly constrained.
