Product details
Overview
MSP430F5510IPTR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 32 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (8 channels: 6 external, 2 internal), two USCI modules (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 MSP430F5510IPTR datasheet, MSP430F5510IPTR pinout, MSP430F5510IPTR application, or MSP430F5510IPTR equivalent, key selection criteria include USB PHY integration, LPM4.5 shutdown current (0.18 µA), 48-pin LQFP package compatibility, and dual-USCI support with port-mapped flexibility on P4.
Technical Context
The MSP430F5510IPTR implements a unified clock system with FLL stabilization, VLO/REFO/XT1/XT2 sources, and programmable LDO core regulation. Its USB subsystem includes integrated 3.3-V/1.8-V power rails, USB-PLL, and eight bidirectional endpoints - enabling self-powered or bus-powered device operation without external transceivers.
Power management supports five low-power modes (LPM0–LPM4.5) with sub-µA retention in standby (LPM3: 1.9 µA at 2.2 V) and wake-up < 5 µs. Peripheral mapping on Port 4 is controlled via the port mapping controller, limiting simultaneous USCI function availability per pin assignment.
Key Specifications

FAQ
What USB speed and device class support does the MSP430F5510IPTR provide?
The MSP430F5510IPTR supports full-speed USB 2.0 (12 Mbps) with integrated PHY and eight bidirectional endpoints. It natively implements USB device classes including CDC (virtual COM port), HID, and MSC via firmware - no external USB controller required. The USB subsystem includes dedicated 3.3-V and 1.8-V regulators and USB-PLL for clock generation.
Does the MSP430F5510IPTR require an external crystal for USB operation?
No - the MSP430F5510IPTR uses its integrated USB-PLL with the internal DCO or external XT2 (up to 32 MHz) to generate the precise 48-MHz USB clock. An external 32-kHz crystal (XT1) is optional and used only for RTC accuracy; USB timing is fully self-contained.
How many analog input channels does the MSP430F5510IPTR ADC support in the 48-pin LQFP package?
In the MSP430F5510IPTR LQFP-48 package, the 10-bit ADC supports six external analog inputs (A0–A5 on P6.0–P6.5) plus two internal channels (VeREF+ and VeREF−), totaling eight channels. Channel mapping matches the device-specific pinout - no external mux needed for basic sensor interfacing.
Can the MSP430F5510IPTR operate from a single 3.3-V supply?
Yes - the MSP430F5510IPTR operates from a single 3.3-V supply applied to DVCC/DVSS and AVCC/AVSS. Its integrated LDO generates the required VCORE voltage (1.8 V typical), and the USB subsystem derives 1.8-V and 3.3-V rails internally - eliminating need for external regulators in most USB-powered designs.
What debug interface does the MSP430F5510IPTR use, and how many pins are required?
The MSP430F5510IPTR uses the 2-wire Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins (pins 48 and 47 in LQFP-48). This reduces debug footprint versus 4-pin JTAG and is fully supported by TI's MSP-FET and Code Composer Studio for programming and real-time debugging.
