Product details
Overview
MSP430F5508IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 16 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), two USCI modules (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 MSP430F5508IRGCR datasheet, MSP430F5508IRGCR pinout, MSP430F5508IRGCR application, or MSP430F5508IRGCR equivalent, key selection criteria include USB PHY integration, 48-pin VQFN (RGCR) package compatibility, LPM4.5 shutdown current (0.18 µA), RTC alarm capability, and dual-USCI support with port-mapped flexibility on P4.
Technical Context
The MSP430F5508IRGCR implements a digitally controlled oscillator (DCO) with FLL stabilization, supports multiple clock sources (VLO, REFO, XT1, XT2 up to 32 MHz), and features a unified clock system with programmable LDO core regulation. Its power management includes five low-power modes (LPM0–LPM4.5) with sub-µA standby (1.9 µA in LPM3) and <5 µs wakeup latency.
Peripherals are mapped via port mapping controller (PMC) on Port 4, enabling dynamic assignment of USCI_A1/USCI_B1 functions to P4 pins; USB interface uses dedicated DP/DM/PUR pins with integrated 3.3-V/1.8-V USB power system and USB-PLL.

FAQ
What is the maximum system clock frequency supported by the MSP430F5508IRGCR?
The MSP430F5508IRGCR supports a maximum system clock frequency of 25 MHz, achieved using the integrated digitally controlled oscillator (DCO) with FLL stabilization or external high-frequency crystals (XT2) up to 32 MHz. This enables high-throughput USB transfers and fast ADC sampling while maintaining deterministic real-time response in the MSP430F5508IRGCR's 16-bit architecture.
Does the MSP430F5508IRGCR include an integrated USB transceiver?
Yes, the MSP430F5508IRGCR integrates a full-speed USB 2.0 physical layer (PHY), USB power system (3.3-V and 1.8-V regulators), and USB-PLL - eliminating the need for external USB transceivers. The dedicated DP, DM, and PUR pins provide direct connection to USB connectors, making the MSP430F5508IRGCR a self-contained USB device solution.
How many I/O pins does the MSP430F5508IRGCR expose in its VQFN-48 (RGCR) package?
The MSP430F5508IRGCR in the VQFN-48 (RGCR) package provides 31 general-purpose I/O pins, as confirmed in the Device Comparison table (Table 3-1) and functional block diagrams. These include P1–P6 and PJ ports, with specific allocations for USB, crystal, debug, and analog functions - all consistent across the 48-pin RGZ/PT/RGCR variants.
Can the MSP430F5508IRGCR operate from a single 3.0-V supply?
Yes, the MSP430F5508IRGCR operates across a supply range of 1.8 V to 3.6 V, and is fully specified at 3.0 V. At this voltage, it achieves 115 µA/MHz active-mode current (RAM execution), 1.9 µA standby (LPM3 with RTC), and 0.18 µA shutdown (LPM4.5), making the MSP430F5508IRGCR ideal for single-cell Li-ion or 3-V coin-cell powered applications.
What peripheral modules differentiate the MSP430F5508IRGCR from non-USB MSP430 variants?
The MSP430F5508IRGCR is distinguished by its integrated full-speed USB 2.0 PHY, USB-PLL, dual USCI modules (supporting UART/IrDA/SPI/I²C), and USB-specific power system (VUSB, V18, PUR). These are absent in non-F55x MSP430 families. The MSP430F5508IRGCR also includes enhanced timer resources (TA0/TA1/TA2/TB0) and a 10-bit ADC with window comparator - all co-optimized for USB-synchronized data acquisition.
