Product details
Overview
MSP430F5508IRGCT 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 MSP430F5508IRGCT datasheet, MSP430F5508IRGCT pinout, MSP430F5508IRGCT application, or MSP430F5508IRGCT equivalent, key selection criteria include USB PHY integration, 48-pin VQFN (RGCT) package compatibility, LPM4.5 shutdown current (0.18 µA), 10-bit ADC sampling rate (200 ksps), and dual-USCI support for simultaneous UART + I²C or SPI interfaces.
Technical Context
The MSP430F5508IRGCT implements a unified clock system with FLL stabilization, programmable LDO core regulation, and flexible port mapping via P4 controller - enabling dynamic reassignment of USCI_A1/USCI_B1 functions to pins P4.0–P4.5. Its USB subsystem integrates dedicated 3.3-V/1.8-V power rails, USB-PLL, and eight bidirectional endpoints.
It supports three low-power modes (LPM3, LPM4, LPM4.5) with sub-µA RTC operation and wake-up in under 5 µs. The device uses TI's CPUXV2 core with constant generators and 16-bit RISC architecture, executing from flash at up to 25 MHz with 195 µA/MHz active-mode efficiency at 3 V.

FAQ
What is the maximum system clock frequency supported by the MSP430F5508IRGCT?
The MSP430F5508IRGCT supports a maximum system clock frequency of 25 MHz, achieved using the digitally controlled oscillator (DCO) stabilized by the FLL loop with external or internal reference sources. This frequency enables real-time USB packet processing and high-speed ADC sampling at 200 ksps without external clock components.
Does the MSP430F5508IRGCT require an external USB transceiver?
No, the MSP430F5508IRGCT does not require an external USB transceiver because it integrates a full-speed USB 2.0 PHY, USB-PLL, and dedicated 3.3-V/1.8-V USB power system. Only passive components - including 27-Ω series resistors on DP/DM and a 1.5-kΩ pull-up on PUR - are needed for USB compliance.
How many ADC input channels does the MSP430F5508IRGCT support?
The MSP430F5508IRGCT supports eight total ADC10_A input channels: six external analog inputs (A0–A5 on P6.x) and two internal sources (VeREF+ and VeREF− on P5.0/P5.1). This configuration is confirmed in Table 3-1 of the SLAS645L datasheet for the F5508 variant.
What package type is used for the MSP430F5508IRGCT?
The MSP430F5508IRGCT uses a 48-pin VQFN package with RGCT suffix, measuring 7 mm × 7 mm with an exposed thermal pad. This package is distinct from the 64-pin RGC and 80-pin ZXH variants used by higher-memory members of the same family.
Can the USCI modules on the MSP430F5508IRGCT operate simultaneously?
Yes, both USCI_A1 and USCI_B1 modules on the MSP430F5508IRGCT can operate simultaneously when configured on P4 pins via the port mapping controller. For example, USCI_A1 can run UART while USCI_B1 handles I²C - enabling concurrent host communication and sensor interfacing without resource conflict.
