Product details
Overview
MSP430F5510IRGZR 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. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5510IRGZR datasheet, MSP430F5510IRGZR pinout, MSP430F5510IRGZR application, or MSP430F5510IRGZR equivalent, key selection criteria include USB PHY integration, 48-pin VQFN package compatibility, LPM4.5 shutdown current (0.18 µA), RTC alarm capability, and dual-USCI support for simultaneous UART + I²C communication in portable measurement designs.
Technical Context
The MSP430F5510IRGZR implements a unified clock system with FLL stabilization, programmable LDO core regulation, and multiple low-frequency sources (VLO, REFO, XT1, XT2). Its power management supports five low-power modes (LPM0–LPM4.5), enabling sub-2 µA RTC-active standby and 5 µs wake-up latency.
Peripherals are mapped via port mapping controller on P4, limiting simultaneous USCI signal availability; USB functionality requires dedicated DP/DM/PUR pins and internal USB-LDO/USB-PLL. The device uses CPUXV2 core with constant generators for optimized code density and includes three-channel DMA for autonomous peripheral transfers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with constant generators; enables high code efficiency for embedded firmware in resource-constrained applications. |
| Flash / RAM | 32 KB flash + 6 KB SRAM (4 KB general-purpose + 2 KB USB-dedicated); supports in-system programming without external voltage. |
| USB Interface | Full-speed USB 2.0 with integrated PHY, 3.3-V/1.8-V power system, and 8 IN/8 OUT endpoints; eliminates need for external transceiver. |
| ADC10_A | 10-bit SAR ADC with 200 ksps sampling, window comparator, and 8 input channels (6 external analog inputs + 2 internal references). |
| Low-Power Modes | LPM4.5 draws 0.18 µA at 3 V; LPM3 with RTC active draws 1.9 µA at 2.2 V - enables multi-year battery life in always-on sensing nodes. |
| Timers | Four 16-bit timers: TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC shadow registers); supports PWM, capture, and real-time event sequencing. |
| USCI Modules | Two USCI peripherals: USCI_A0/A1 (UART/IrDA/SPI) and USCI_B0/B1 (I²C/SPI); configurable via port mapping on P4. |
Pinout & Package
VQFN-48 (RGZ) package, 7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad (recommended connection to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TA0CLK/ACLK | Timer A0 clock input / Auxiliary clock output | Provides low-frequency timing source for timer subsystem or system clock distribution. |
| P1.6/TA1CLK/CBOUT | Timer A1 clock input / Comparator B output | Enables synchronized timer operation or routed comparator logic output to external circuitry. |
| P2.2/TA2CLK/SMCLK | Timer A2 clock input / Sub-main clock output | Delivers system clock derivative for peripheral timing or external clocking of companion ICs. |
| P3.0–P3.4 / P4.0–P4.5 | USCI_A1/B1 signal multiplexing (SPI/I²C/UART) | Configurable via port mapping controller; allows flexible interface assignment but not all functions simultaneously. |
| PU.0/DP, PU.1/DM, PUR | USB differential data pair + pull-up resistor control | Direct full-speed USB connectivity; PUR enables software-controlled device enumeration on host detection. |
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire debug I/O | Single-pin debug interface reduces PCB footprint vs JTAG; supports in-circuit programming and real-time debugging. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB 2.0 PHY | Eliminates external transceiver and level-shifting components, reducing BOM cost and board area in USB-peripheral designs. |
| Programmable LDO core regulator | Allows dynamic core voltage scaling to match performance needs, optimizing active-mode power across operating frequencies. |
| Port mapping controller (P4) | Enables runtime reassignment of USCI signals to different P4 pins, increasing design flexibility without hardware change. |
| Three-channel DMA | Offloads CPU during ADC conversions, USB transfers, or timer-triggered memory moves - critical for deterministic real-time response. |
| RTC with alarm and calibration | Supports precise timekeeping and wake-up events independent of main CPU state, enabling scheduled sensor sampling in LPM3. |
Applications
| USB Data Logger | Wireless Headset Controller |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5529IPN | 64-pin LQFP package, 512 KB flash, 64 KB RAM, same USB/USCI/peripheral set; no ADC window comparator. | Targets higher-firmware-complexity USB hosts (e.g., USB device class drivers) requiring more memory and I/O. | Select when >32 KB flash or >47 GPIOs are required; not drop-in due to package and pin count mismatch. |
| MSP430FR5969IRHAT | Ferroelectric RAM (FRAM) instead of flash; 64 KB FRAM, 2 KB RAM; no integrated USB PHY; requires external transceiver. | Suitable for frequent write-cycle applications (e.g., data logging with 100k+ daily writes) where flash endurance is limiting. | Choose for extreme write endurance and instant non-volatility; USB functionality must be added externally. |
Compared with MSP430F5529IPN and MSP430FR5969IRHAT, the MSP430F5510IRGZR delivers optimal balance of USB integration, ultra-low standby power, and compact 48-pin VQFN packaging - making it ideal for space- and battery-constrained USB peripherals where flash endurance is sufficient and external PHYs are undesirable.

FAQ
What is the maximum system clock frequency supported by the MSP430F5510IRGZR?
The MSP430F5510IRGZR supports up to 25 MHz system clock frequency using the integrated FLL with XT2 crystal (up to 32 MHz) or internal DCO. This enables high-throughput USB data transfer and real-time signal processing while maintaining ultra-low-power architecture compliance.
Does the MSP430F5510IRGZR require an external USB transceiver?
No, the MSP430F5510IRGZR includes a fully integrated USB 2.0 full-speed PHY, USB-LDO, and USB-PLL. Only passive components (240 Ω pull-up on D+, 1.5 kΩ pull-down on D−, and decoupling capacitors) are required - no external transceiver is needed for USB connectivity.
How many analog input channels does the ADC10_A module support on the MSP430F5510IRGZR?
The ADC10_A module on the MSP430F5510IRGZR supports 8 total input channels: 6 external analog inputs (A0–A5 on P6.x) and 2 internal references (VeREF+ and VeREF− on P5.0/P5.1), enabling simultaneous sensor and supply-monitoring capability without external muxing.
What low-power mode achieves the lowest current consumption on the MSP430F5510IRGZR?
The MSP430F5510IRGZR achieves its lowest active-retention current in LPM4.5 (shutdown mode), drawing just 0.18 µA at 3 V. In this mode, the supply supervisor remains active and full RAM retention is maintained, enabling rapid wake-up with no register restoration overhead.
Can the MSP430F5510IRGZR operate from a single 1.8-V supply?
Yes, the MSP430F5510IRGZR is specified for operation from 1.8 V to 3.6 V. At 1.8 V, it supports reduced maximum clock frequency (typically ≤ 8 MHz) and retains full peripheral functionality including USB (with appropriate VBUS detection), ADC, and timers - ideal for single-cell Li-ion or coin-cell powered devices.
