Product details
Overview
MSP430A134IRGCR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring USB 2.0 physical layer, integrated USB-PLL and USB-LDO, 64 KB flash, 4 KB + 2 KB RAM, and 47 general-purpose I/O pins in a 64-pin VQFN package. It operates from 1.8 V to 3.6 V and supports real-time clock (RTC), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), hardware multiplier, DMA, and comparator. It targets battery-powered USB-connected sensor nodes and portable data loggers.
For engineers reviewing the MSP430A134IRGCR datasheet, MSP430A134IRGCR pinout, MSP430A134IRGCR application, or MSP430A134IRGCR equivalent, key selection criteria include USB PHY integration, LPM3 standby current (1.9 µA at 3.0 V), wake-up time (3.5 µs), ADC channel count (12 external + 2 internal), and VQFN-64 thermal performance (θJA = 32.5°C/W).
Technical Context
The MSP430A134IRGCR implements a digitally controlled oscillator (DCO) with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and low-power internal sources (VLO, REFO). Its unified clock system enables dynamic clock gating and mode transitions without external components.
It integrates a full-speed USB 2.0 transceiver with on-die termination, differential DP/DM I/O, integrated 3.3-V/1.8-V USB power regulation, and endpoint FIFO management. The 12-bit ADC12_A module supports autoscan across 12 channels (10 external, 2 internal) with sample rates up to 200 ksps and built-in reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power USB microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5528IRGC | Same 64-pin VQFN package, identical USB/ADC/timer peripherals, but 96 KB flash and 6 KB + 2 KB RAM | Higher flash/RAM supports larger USB class stacks (e.g., MSC, DFU) or complex sensor fusion algorithms | Select MSP430F5528IRGC when firmware size exceeds 64 KB or additional RAM is needed for USB descriptor tables or buffering |
| MSP430F5514IRGC | Same package and pinout, but reduced feature set: no ADC12_A (only comparator), 32 KB flash, 4 KB + 2 KB RAM | Suitable for pure USB control applications without analog sensing-e.g., USB-to-UART bridges or HID-only devices | Choose MSP430F5514IRGC for cost-sensitive USB interface tasks where ADC is unnecessary and flash demand is ≤32 KB |
Compared with MSP430A134IRGCR, MSP430F5528IRGC offers higher memory headroom for advanced USB functionality, while MSP430F5514IRGC trades analog capability for lower cost and smaller code footprint-both share identical USB PHY, clock system, and low-power behavior.

FAQ
What USB speed and device classes does the MSP430A134IRGCR support?
The MSP430A134IRGCR supports full-speed USB 2.0 (12 Mbps) with integrated PHY, USB-PLL, and USB-LDO. It implements standard USB device classes including CDC ACM (virtual COM port), HID (keyboard/mouse), and MSC (mass storage) via firmware. The MSP430A134IRGCR does not support high-speed USB or USB host functionality-only device mode.
Does the MSP430A134IRGCR include a hardware ADC, and what are its key specs?
Yes, the MSP430A134IRGCR includes a 12-bit ADC12_A module with 200 ksps maximum sample rate, autoscan across 12 channels (10 external, 2 internal), and selectable internal references (1.5 V or 2.5 V). It supports sample-and-hold, window comparator, and burst conversion modes-all operating within the specified 1.8–3.6 V supply range.
What is the lowest power consumption mode of the MSP430A134IRGCR, and what peripherals remain active?
The lowest power mode is LPM4.5, drawing 0.18 µA at 3.0 V with full RAM retention and supply supervisor active. In LPM3 (1.9 µA at 3.0 V), the RTC with 32-kHz crystal, watchdog timer, supply supervisor, and full RAM are retained-enabling calendar-based wake-up with minimal energy use. The MSP430A134IRGCR achieves this via its integrated LDO and optimized power management module.
Is the MSP430A134IRGCR pin-compatible with other MSP430F55xx devices in the same VQFN-64 package?
Yes, the MSP430A134IRGCR shares identical pinout, electrical characteristics, and package dimensions (VQFN-64, RGCR) with MSP430F5528IRGC, MSP430F5526IRGC, MSP430F5524IRGC, MSP430F5522IRGC, MSP430F5514IRGC, and MSP430F5513IRGC. This allows direct PCB reuse across the family when selecting different flash/RAM or peripheral configurations.
What development tools are officially supported for the MSP430A134IRGCR?
Texas Instruments officially supports the MSP430A134IRGCR with Code Composer Studio IDE (v12+), MSP430Ware™ driver library, and the MSP-TS430RGC64USB 64-pin target development board. While the MSP-EXP430F5529LP LaunchPad is designed for the 80-pin variant, its debug interface (SBW) is compatible with the MSP430A134IRGCR when using the RGC64 target board.
