Product details
Overview
MSPM0L1306TRHBR from Texas Instruments is an Arm® Cortex®-M0+ 32-bit microcontroller operating up to 32 MHz, featuring 64 KB flash, 4 KB SRAM, and a 12-bit 1.68-Msps ADC with 10 external channels-designed for ultra-low-power battery management and smart metering systems requiring extended temperature operation (–40°C to 125°C) and wide supply range (1.62 V to 3.6 V).
For engineers reviewing the MSPM0L1306TRHBR datasheet, MSPM0L1306TRHBR pinout, MSPM0L1306TRHBR application, or MSPM0L1306TRHBR equivalent, this page delivers verified technical context, package-specific pin functions, low-power mode timing, analog peripheral integration details, and validated alternative options for embedded control and precision sensing designs.
Technical Context
The MSPM0L1306TRHBR integrates a high-accuracy ±1.2% internal SYSOSC (4–32 MHz) and ±3% LFOSC (32 kHz), eliminating external crystals while supporting full-speed operation and sub-µA STANDBY mode with 32-kHz timer retention. Its analog subsystem includes two zero-drift chopper op-amps (0.5 µV/°C drift, 6-pA bias), one GPAMP, and a comparator with integrated 8-bit DAC and 32-ns propagation delay.
Digital intelligence includes a 3-channel DMA, four 16-bit timers (8 PWM channels total), event fabric signaling, and dual UART/I²C/SPI interfaces-with LIN, IrDA, DALI, Smart Card, SMBus, and PMBus protocol support-all operational in STANDBY mode for responsive wake-up in energy-constrained applications.

FAQ
What is the maximum operating frequency and core architecture of the MSPM0L1306TRHBR?
The MSPM0L1306TRHBR features an Arm Cortex-M0+ 32-bit processor core with a maximum operating frequency of 32 MHz. This architecture delivers deterministic real-time performance while maintaining ultra-low power consumption-verified in TI's SLASEX0D datasheet with ±1.2% internal oscillator accuracy across temperature and voltage. The MSPM0L1306TRHBR uses this core to execute control loops, communication protocols, and sensor processing without external clock components.
Does the MSPM0L1306TRHBR support hardware debugging, and what interface is used?
Yes, the MSPM0L1306TRHBR supports 2-pin serial wire debug (SWD) via dedicated PA19/SWDIO and PA20/SWCLK pins. This interface enables full programming, real-time tracing, and breakpoint debugging using standard tools like Code Composer Studio™ and TI's MSP Software Development Kit. The MSPM0L1306TRHBR implements SWD compliance per ARM CoreSight specifications, allowing seamless integration into existing development workflows without requiring JTAG headers or additional debug circuitry.
How many analog-to-digital converter (ADC) channels does the MSPM0L1306TRHBR provide, and what is its resolution and speed?
The MSPM0L1306TRHBR integrates a single 12-bit successive-approximation ADC with a maximum sampling rate of 1.68 million samples per second (Msps) and up to 10 external analog input channels (A0–A9). It also supports configurable internal voltage references (1.4 V or 2.5 V) and direct connection to on-chip temperature sensors. This ADC capability is documented in Section 7.12 of the SLASEX0D datasheet and enables high-fidelity voltage, current, and environmental monitoring in power and metering applications using the MSPM0L1306TRHBR.
What low-power modes are available on the MSPM0L1306TRHBR, and what is the lowest current draw?
The MSPM0L1306TRHBR offers four configurable low-power modes: RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA with 32-kHz timer running and full SRAM retention), and SHUTDOWN (61 nA with IO wakeup capability). These values are measured and specified in TI's SLASEX0D datasheet Section 7.5. The SHUTDOWN mode makes the MSPM0L1306TRHBR especially suitable for battery-powered devices requiring decade-long operation, such as smoke detectors and remote utility meters-where the MSPM0L1306TRHBR maintains system readiness with minimal energy drain.
Is the MSPM0L1306TRHBR pin-compatible with other members of the MSPM0L130x family in the same package?
Yes, the MSPM0L1306TRHBR is fully pin-compatible with other MSPM0L130x devices offered in the 32-pin VQFN (RHB) package-including MSPM0L1305TRHBR and MSPM0L1304TRHBR-as confirmed in TI's Device Comparison table (Table 5-1, SLASEX0D). All share identical pin functions, electrical characteristics, and package dimensions (5 mm × 5 mm), enabling drop-in replacement during design iteration or cost optimization-provided firmware accommodates differences in flash/SRAM size and peripheral enablement within the MSPM0L1306TRHBR feature set.
