Product details
Overview
MSP430F5510IRGCT 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 (200 ksps, 8 channels), dual USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, and hardware multiplier. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring USB connectivity and precise timing.
For engineers reviewing the MSP430F5510IRGCT datasheet, MSP430F5510IRGCT pinout, MSP430F5510IRGCT application, or MSP430F5510IRGCT equivalent, key selection criteria include USB PHY integration, 47 I/O count in 64-pin VQFN, LPM4.5 shutdown current (0.18 µA), RTC alarm capability, and port-mapped USCI flexibility on P4 for embedded host interface design.
Technical Context
The MSP430F5510IRGCT implements a unified clock system with FLL stabilization, dual crystal oscillators (XT1 up to 32 kHz, XT2 up to 32 MHz), VLO and REFO internal sources, and programmable LDO core regulation. Its CPUXV2 core supports 25-MHz operation with constant generators for optimized code density.
Peripherals are organized around three-channel DMA, port mapping controller (PMC) for dynamic USCI signal routing on P4, and independent power domains (DVCC/AVCC/VUSB/V18) enabling selective peripheral activation. The USB subsystem includes integrated 3.3-V/1.8-V regulators, USB-PLL, and eight bidirectional endpoints - all managed without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with constant generators; enables compact, deterministic firmware for real-time sensor processing. |
| Flash / RAM | 32 KB flash (in-system programmable) + 4 KB main RAM + 2 KB USB SRAM; USB SRAM usable as general-purpose RAM when USB inactive. |
| USB Interface | Full-speed (12 Mbps) USB 2.0 with integrated PHY, PLL, and dual-voltage power system; eliminates external transceiver and voltage translators. |
| ADC Performance | 10-bit SAR ADC at 200 ksps with 8 input channels (6 external, 2 internal); includes window comparator for autonomous threshold monitoring. |
| Low-Power Modes | LPM4.5 draws 0.18 µA at 3 V; wake-up from LPM3 in <5 µs; RTC + watchdog + supervisor active in standby with full RAM retention. |
| Timer Resources | Four 16-bit timers: TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC shadow registers); supports PWM, capture, and interval timing with DMA trigger capability. |
| I/O Count & Flexibility | 47 GPIO pins in 64-pin VQFN (RGC); USCI functions dynamically mapped to P4 via port mapping controller - no fixed pinout constraints. |
Pinout & Package
VQFN package with 64 pins, 9 mm × 9 mm body size, exposed thermal pad (recommended connection to DVSS). Pinout conforms to TI's RGC mechanical standard (SLAS645L, Figure 4-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TA0CLK/ACLK | Primary timer clock / auxiliary low-frequency clock input | Accepts external 32.768-kHz crystal or digital clock; feeds ACLK domain for RTC and low-power peripherals. |
| P5.4/XIN & P5.5/XOUT | XT1 oscillator terminals | Supports 32.768-kHz watch crystal; essential for RTC accuracy and low-power sleep mode timing. |
| PU.0/DP & PU.1/DM | USB differential data pair | Direct full-speed USB physical layer interface; requires no external termination or ESD protection diodes per TI design guidelines. |
| PUR | USB pull-up resistor control | Internal 1.5-kΩ pull-up to VBUS enables USB device enumeration; controlled by software for attach/detach signaling. |
| RST/NMI/SBWTDIO | Reset / non-maskable interrupt / debug I/O | Single-pin multifunction interface for reset assertion, NMI event detection, and Spy-Bi-Wire programming/debug access. |
| VCORE | Core voltage supply | Output of integrated LDO; supplies regulated 1.8 V to CPU and digital logic; voltage level programmable via PMM registers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB 2.0 PHY + power system | Eliminates external USB transceiver, 3.3-V regulator, and 1.8-V LDO - reduces BOM count and PCB area by ≥5 components. |
| Port mapping controller (PMC) | Enables runtime reassignment of USCI_A1/USCI_B1 signals to any of eight P4 pins - simplifies layout and supports multiple interface configurations from one PCB. |
| Three-channel DMA | Offloads CPU during ADC conversions, USB transfers, and timer captures - enables zero-wait-state data movement while CPU remains in LPM3. |
| Programmable LDO with VCORE output | Adjusts core voltage between 1.8 V and 2.2 V to trade performance vs. power; supports dynamic voltage scaling for burst-mode execution. |
| RTC with alarm and calibration | Hardware real-time clock runs independently in LPM3/LPM4; alarm interrupt wakes CPU; ±2 ppm calibration register compensates crystal drift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller-with-USB applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5529IPN | 64-pin LQFP package; identical peripheral set but higher 16-KB RAM (6 KB + 2 KB USB SRAM); same 32 KB flash and USB PHY. | Preferred where PCB layout favors LQFP over VQFN or where additional RAM is required for complex USB descriptors or buffering. | Select MSP430F5529IPN if board space allows larger footprint and firmware requires >4 KB main RAM; pinout differs - not drop-in compatible. |
| MSP430F5638IZQW | 80-pin nFBGA (5 mm × 5 mm); adds LCD controller and enhanced DMA; same USB, ADC, and timer resources; 256 KB flash. | Suitable for human-interface devices with segment LCD display; higher flash supports bootloader + application separation. | Choose MSP430F5638IZQW only when LCD driving or >32 KB code storage is mandatory; package and pinout incompatible with MSP430F5510IRGCT. |
Compared with MSP430F5529IPN and MSP430F5638IZQW, the MSP430F5510IRGCT delivers optimal balance of USB integration, ultra-low-power operation, and compact 64-pin VQFN packaging - making it ideal for space-constrained, battery-operated USB peripherals where RAM demand stays within 4 KB.

FAQ
What USB speed and device class support does the MSP430F5510IRGCT provide?
The MSP430F5510IRGCT supports full-speed USB 2.0 (12 Mbps) as a device-only endpoint with integrated PHY, PLL, and dual-voltage regulators. It does not support USB host or OTG modes. TI provides USB stack libraries for CDC, HID, and MSC classes - all fully compatible with the MSP430F5510IRGCT's eight bidirectional endpoints and DMA-accelerated transfers.
Does the MSP430F5510IRGCT require external crystals for USB operation?
No - the MSP430F5510IRGCT uses its internal USB-PLL locked to the high-frequency XT2 oscillator (up to 32 MHz) for USB timing; an external crystal on XT2 is required for USB compliance, but no separate USB-specific crystal is needed. The 32.768-kHz XT1 crystal is optional and used only for RTC accuracy or low-power clocking, not USB functionality.
How many I/O pins are available on the MSP430F5510IRGCT in its RGC package?
The MSP430F5510IRGCT in the 64-pin VQFN (RGC) package provides 47 general-purpose I/O pins. All pins support configurable drive strength, Schmitt-trigger inputs, and interrupt capability. USCI functions are routed dynamically via the port mapping controller on P4, allowing flexible peripheral pin assignment without hardware redesign.
What is the lowest power consumption state supported by the MSP430F5510IRGCT?
The MSP430F5510IRGCT achieves 0.18 µA in LPM4.5 (shutdown mode) at 3 V with VCORE powered down and only the RST/NMI pin active. This mode retains no RAM but offers fastest wake-up among deepest sleep states. For full RAM retention with lowest active current, LPM3 draws 1.9 µA at 2.2 V with RTC, watchdog, and supply supervision enabled.
Can the MSP430F5510IRGCT operate without an external debugger interface?
Yes - the MSP430F5510IRGCT supports in-system programming via its built-in bootloader (BSL) using UART or USB, eliminating the need for JTAG or Spy-Bi-Wire hardware during field firmware updates. However, JTAG/SBW (via RST/NMI and TEST/SBWTCK pins) remains available for full-featured debugging and boundary-scan testing during development.
