For engineers reviewing the MSPM0L1303TRGER datasheet, MSPM0L1303TRGER pinout, MSPM0L1303TRGER application, or MSPM0L1303TRGER equivalent, this page delivers verified package mapping (16-pin WQFN), low-power mode current values (1.0 µA STANDBY, 61 nA SHUTDOWN), analog peripheral configuration options (VREF selection, OPA gain 1–32×), and real-world use-case guidance for precision sensor interfacing and energy-constrained control.

Technical Context

The MSPM0L1303TRGER integrates a 32-MHz Arm Cortex-M0+ core with tightly coupled analog subsystems: its ADC supports configurable 1.4-V/2.5-V internal reference and programmable analog routing between ADC, OPAs, COMP, and DAC; dual chopper op-amps deliver 0.5-µV/°C drift and 6-pA input bias current with integrated gain stages.

Digital intelligence includes a 3-channel DMA, four 16-bit timers (8 PWM channels total), event fabric signaling, and communication interfaces - two UARTs (one LIN-capable), two I²C (one FM+, SMBus/PMBus), and one SPI (16 Mbit/s) - all supporting wakeup from STOP/STANDBY modes with sub-µs latency.

FAQ

What is the maximum operating frequency and core architecture of the MSPM0L1303TRGER?

The MSPM0L1303TRGER features an Arm Cortex-M0+ CPU core with a maximum operating frequency of 32 MHz. This architecture delivers efficient 32-bit processing while maintaining ultra-low power consumption - validated across the full –40°C to 125°C temperature range and 1.62 V to 3.6 V supply voltage window. The MSPM0L1303TRGER achieves 71 µA/MHz in RUN mode (CoreMark), confirming its suitability for energy-sensitive real-time control tasks.

How many analog input channels does the MSPM0L1303TRGER support, and what ADC resolution is provided?

The MSPM0L1303TRGER supports 9 external analog input channels (A0–A6 plus additional routed pins) with its integrated 12-bit successive-approximation ADC, capable of 1.68 million samples per second. The ADC includes configurable internal voltage references (1.4 V or 2.5 V) and hardware routing to OPAs and comparators - enabling direct sensor signal conditioning without external components. This specification is confirmed in the Device Comparison table and Section 7.12 of the datasheet.

Does the MSPM0L1303TRGER include operational amplifiers, and what are their key electrical characteristics?

Yes, the MSPM0L1303TRGER integrates two zero-drift, zero-crossover chopper operational amplifiers (OPA0 and OPA1). Key confirmed characteristics include 0.5 µV/°C input offset drift, 6-pA input bias current, and programmable gain from 1× to 32×. These OPAs support direct connection to the ADC and comparator, enabling precision analog front-ends for sensor interfaces - all documented in the "High-performance analog peripherals" section and Table 7.17 of the datasheet.

What low-power modes are available on the MSPM0L1303TRGER, and what are their typical current draws?

The MSPM0L1303TRGER offers four defined low-power modes: RUN (71 µA/MHz), STOP (151 µA at 4 MHz), STANDBY (1.0 µA with 32-kHz timer active and full SRAM retention), and SHUTDOWN (61 nA with IO wakeup capability). These values are measured and specified in Section 7.5 of the datasheet under recommended operating conditions. STANDBY mode enables microsecond-scale wakeup (3.2 µs to 32 MHz), making it ideal for periodic sensing applications.

Which communication interfaces are supported by the MSPM0L1303TRGER, and do they support low-power operation?

The MSPM0L1303TRGER supports two UARTs (one LIN-capable), two I²C interfaces (one FM+, both SMBus/PMBus-compatible), and one SPI (up to 16 Mbit/s). All interfaces support wakeup from STOP and STANDBY modes - confirmed in the "Enhanced communication interfaces" feature list and Section 7.20–7.21 of the datasheet. UART0 and I²C0 retain functionality in STANDBY with configurable clock sources, enabling always-on communication readiness.
