Product details
Overview
MSP430F5510IPT 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 MSP430F5510IPT datasheet, MSP430F5510IPT pinout, MSP430F5510IPT application, or MSP430F5510IPT equivalent, key selection criteria include USB PHY integration, LQFP-48 package compatibility, 1.8–3.6 V operation, sub-2 µA LPM3 current, and dual-USCI support with port-mapped flexibility on P4.
Technical Context
The MSP430F5510IPT implements a unified clock system with FLL stabilization, programmable LDO core regulation, and multiple low-power oscillators (VLO, REFO, XT1, XT2 up to 32 MHz). Its CPUXV2 core executes instructions in single-cycle mode with constant generators for optimized code density.
USB functionality is fully integrated with dedicated 3.3-V/1.8-V power rails, USB-PLL, eight endpoints, and DP/DM/PUR I/Os. The port mapping controller on P4 enables dynamic assignment of USCI_A1/B1 signals, though simultaneous use of all functions is constrained by pin multiplexing in the 48-pin LQFP package.

FAQ
What is the maximum operating frequency of the MSP430F5510IPT?
The MSP430F5510IPT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization using external crystals (XT1 up to 32 kHz, XT2 up to 32 MHz) or internal references. This frequency enables real-time processing of USB transactions and sensor data without compromising ultra-low-power operation in active mode.
Does the MSP430F5510IPT require an external crystal for USB operation?
No - the MSP430F5510IPT integrates a USB-PLL that locks to the internal DCO or external XT2 source, eliminating the need for a separate 48-MHz crystal. USB timing compliance is maintained using the on-chip PLL referenced to XT2 (up to 32 MHz) or the DCO, with built-in jitter tolerance per USB 2.0 full-speed specifications.
How many USB endpoints does the MSP430F5510IPT support?
The MSP430F5510IPT supports eight bidirectional endpoints (four IN and four OUT), configurable as control, interrupt, bulk, or isochronous transfers. Endpoint 0 is reserved for standard USB control transfers, while endpoints 1–7 are user-configurable in firmware - sufficient for CDC, HID, and custom class implementations without external USB controller logic.
Can the MSP430F5510IPT operate from a single 3.3-V supply?
Yes - the MSP430F5510IPT operates from a single 3.3-V supply applied to DVCC and AVCC pins. Its integrated LDO regulates VCORE to 1.8 V for the CPU and peripherals, while the USB power system independently generates V18 (1.8 V) and VUSB (3.3 V) from the same input, meeting USB electrical requirements without external regulators.
What is the function of the PUR pin on the MSP430F5510IPT?
The PUR (Pull-Up Resistor) pin on the MSP430F5510IPT controls the internal 1.5-kΩ USB pull-up resistor on the DP line. Driving PUR high enables the pull-up, signaling USB host detection and initiating device enumeration; driving PUR low disables it, placing the device in unconnected state - enabling firmware-controlled USB attach/detach behavior.
