Product details
Overview
MSP430F5507IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated USB 2.0 PHY, 32 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), one USCI (supporting UART/IrDA/SPI/I²C), four 16-bit timers, RTC, and hardware multiplier-designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5507IRGZR datasheet, MSP430F5507IRGZR pinout, MSP430F5507IRGZR application, or MSP430F5507IRGZR equivalent, key selection criteria include USB 2.0 full-speed integration, 31 I/O pins in 48-pin VQFN, LPM4.5 shutdown current of 0.18 µA, and single-USCI peripheral configuration versus higher-pin-count family members.
Technical Context
The MSP430F5507IRGZR implements a 16-bit RISC CPU with constant generators and extended memory addressing, paired with a unified clock system featuring FLL stabilization, VLO/REFO internal sources, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals. Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
It integrates full-speed USB 2.0 via on-die PHY, dedicated USB-LDO, and USB-PLL, with eight endpoints (4 IN/4 OUT), while its single USCI module supports configurable UART, IrDA, SPI, or I²C through port mapping on P4-limiting simultaneous protocol availability per pin assignment constraints in the RGZ package.

FAQ
What is the maximum system clock frequency supported by the MSP430F5507IRGZR?
The MSP430F5507IRGZR supports a maximum system clock (MCLK) frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL control loop. This allows high-speed instruction execution while maintaining compatibility with USB full-speed timing requirements. The device achieves this performance within its 1.8–3.6 V operating range and maintains ultra-low active-mode current of 195 µA/MHz at 8 MHz and 3 V.
Does the MSP430F5507IRGZR support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5507IRGZR supports dual crystal oscillator inputs: a 32-kHz watch crystal (XT1) for low-frequency, low-power RTC and ACLK generation, and a high-frequency crystal up to 32 MHz (XT2) for SMCLK and MCLK. Both are fully supported in the 48-pin RGZ package, with dedicated XIN/XOUT pins (P5.4/P5.5 for XT1; P5.2/P5.3 for XT2), enabling precise timing across all power modes.
How many USB endpoints does the MSP430F5507IRGZR provide, and what types are supported?
The MSP430F5507IRGZR provides eight USB endpoints-four IN and four OUT-fully compliant with USB 2.0 full-speed (12 Mbps) specification. It supports control, interrupt, bulk, and isochronous transfer types via its integrated USB-PHY and endpoint controller. Endpoint configuration is managed through USB registers, and the 2 KB USB SRAM serves as dedicated buffer memory for endpoint data staging.
Can the MSP430F5507IRGZR operate without an external crystal?
Yes, the MSP430F5507IRGZR can operate without external crystals using its internal oscillators: the VLO (≈10 kHz) for basic LPM3 operation and the DCO with FLL for active-mode clocks. However, USB communication and RTC accuracy require external crystals-XT1 (32 kHz) for RTC and XT2 (4–25 MHz) for USB frame timing. For non-USB applications, full functionality is achievable with internal sources only.
What is the role of the VCORE pin on the MSP430F5507IRGZR, and how should it be decoupled?
The VCORE pin on the MSP430F5507IRGZR delivers the regulated core voltage (1.8 V nominal) from the integrated LDO. It must be decoupled with a 1-µF ceramic capacitor placed as close as possible to the VCORE and DVSS pins. This decoupling ensures stable core voltage under dynamic load conditions-especially critical during USB packet transmission and ADC conversions-and prevents brownout resets or timing violations in the CPU and peripherals.
