FAQ
What is the maximum system clock frequency supported by the MSP430F5506IRGZT?
The MSP430F5506IRGZT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization using either internal reference (REFO) or external crystals (XT1/XT2). This frequency is fully operational across the 1.8–3.6 V supply range and enables real-time USB packet processing and high-speed ADC sampling at 200 ksps.
Does the MSP430F5506IRGZT support crystal oscillators for both low-frequency and high-frequency operation?
Yes, the MSP430F5506IRGZT supports dual crystal configurations: a 32-kHz watch crystal on XIN/XOUT (XT1) for RTC and low-power timing, and a high-frequency crystal up to 32 MHz on XT2IN/XT2OUT for system clock generation. Both are fully supported in all low-power modes except LPM4.5, where only the VLO remains active.
How many USB endpoints does the MSP430F5506IRGZT provide, and what types are supported?
The MSP430F5506IRGZT provides eight bidirectional USB endpoints (four IN, four OUT), supporting control, interrupt, bulk, and isochronous transfer types. Endpoint configuration is handled in firmware via the USB module registers, and the integrated USB-PLL ensures precise 48-MHz clock generation required for full-speed USB compliance.
Can the MSP430F5506IRGZT operate from a single 3.3-V USB supply without external regulators?
Yes - the MSP430F5506IRGZT integrates a dedicated USB power system (USB-LDO) that accepts 3.3 V (VBUS) and generates regulated 3.3-V and 1.8-V supplies for the USB PHY and digital logic. DVCC and AVCC can be supplied directly from VBUS, eliminating need for external regulators in bus-powered designs.
What debug interface is supported on the MSP430F5506IRGZT, and how many pins does it require?
The MSP430F5506IRGZT supports Spy-Bi-Wire (SBW), a 2-wire subset of JTAG, using only TEST/SBWTCK (pin 47) and RST/NMI/SBWTDIO (pin 48). This enables full programming, debugging, and boundary-scan capability with minimal PCB footprint - critical for compact 48-pin VQFN layouts.
