Product details
Overview
MSP430F5510IRGZT 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 requiring USB connectivity.
For engineers reviewing the MSP430F5510IRGZT datasheet, MSP430F5510IRGZT pinout, MSP430F5510IRGZT application, or MSP430F5510IRGZT equivalent, key selection criteria include USB PHY integration, 48-pin VQFN package constraints, port-mapped USCI signal routing on P4, and LPM3 current of 1.9 µA at 3 V with RTC active.
Technical Context
The MSP430F5510IRGZT implements a unified clock system with FLL stabilization, dual crystal oscillators (XT1 for 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 efficiency.
USB functionality includes integrated 3.3-V/1.8-V power system, USB-PLL, eight endpoints (4 IN/4 OUT), and DP/DM/PUR pins routed to PU.0/PU.1/VSSU - all physically present in the 48-pin RGZ package. Port mapping controller (PMC) on P4 enables flexible USCI signal assignment but limits simultaneous peripheral pinouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with constant generators; enables high code density and deterministic real-time execution. |
| Flash / RAM | 32 KB flash (in-system programmable); 4 KB main + 2 KB USB SRAM (usable as general RAM when USB inactive). |
| USB Interface | Full-speed USB 2.0 compliant with integrated PHY, PLL, and dual-voltage power system - eliminates external transceiver. |
| ADC10_A | 10-bit SAR ADC sampling at 200 ksps with 8 input channels (6 external analog inputs + 2 internal references). |
| Low-Power Modes | LPM3: 1.9 µA @ 3 V with RTC, watchdog, supervisor active and full RAM retention; wake-up <5 µs. |
| Timers | Four 16-bit timers: TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC shadow registers) - supports complex PWM, capture, and interval timing. |
| USCI Modules | Two USCI peripherals: USCI_A0/A1 (UART/IrDA/SPI), USCI_B0/B1 (I²C/SPI); pinout constrained by P4 port mapping in RGZ package. |
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 and system clock domain synchronization. |
| P4.0–P4.5 | Port-mapped USCI signals (STE, SIMO, SOMI, CLK, TXD, RXD) | Configurable via PMC to route USCI_A1/B1 functions; only subset available simultaneously in 48-pin RGZ. |
| PU.0/DP, PU.1/DM, PUR, VSSU | USB differential pair, pull-up resistor control, USB ground | Direct USB physical layer interface; PUR controls device speed detection; VSSU isolates USB analog ground. |
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire debug I/O | Single-pin multifunction interface for reset assertion, NMI event handling, and 2-wire JTAG-like programming/debug. |
| VCORE | Regulated core voltage supply | Output of internal LDO; must be decoupled locally to stabilize 1.8 V core rail for CPU and peripherals. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB PHY + power system | Eliminates external USB transceiver and level-shifting components; reduces BOM count and PCB area. |
| Port mapping controller (P4) | Enables dynamic reassignment of USCI functions to P4 pins - increases design flexibility without adding GPIOs. |
| RTC with alarm and calendar mode | Hardware real-time clock retains time across LPM3/LPM4; supports periodic interrupts and calendar-based wake-up events. |
| Three-channel DMA | Offloads CPU during data transfers (e.g., ADC → RAM, USB IN → memory), reducing active-mode duration and power consumption. |
| Digitally controlled oscillator (DCO) | Enables sub-5-µs wake-up from LPM3/LPM4 to full AM operation - critical for duty-cycled sensor applications. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5510IRGZT?
The MSP430F5510IRGZT supports a maximum system clock (MCLK) frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL loop. This allows high-speed instruction execution while maintaining ultra-low-power operation through dynamic clock gating and multiple low-power modes.
Does the MSP430F5510IRGZT include an integrated USB transceiver?
Yes, the MSP430F5510IRGZT integrates a full-speed USB 2.0 PHY, USB-PLL, and dual-voltage (3.3 V/1.8 V) USB power system. No external USB transceiver is required - DP, DM, PUR, and VSSU pins provide direct physical-layer connectivity.
How many analog input channels does the ADC10_A module support on the MSP430F5510IRGZT?
The ADC10_A module on the MSP430F5510IRGZT 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 flexible sensor and supply monitoring configurations.
What package type and pin count does the MSP430F5510IRGZT use?
The MSP430F5510IRGZT uses a 48-pin VQFN package (RGZ), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This compact, thermally enhanced package is optimized for space-constrained USB-enabled portable designs.
Can the USCI modules on the MSP430F5510IRGZT operate simultaneously in UART and I²C modes?
Yes - the MSP430F5510IRGZT contains two independent USCI modules (USCI_A0/A1 and USCI_B0/B1). USCI_A can be configured for UART/IrDA/SPI, and USCI_B for I²C/SPI concurrently. However, in the 48-pin RGZ package, pin availability is limited by the port mapping controller on P4, requiring careful signal assignment.
