FAQ

What is the maximum operating frequency and core architecture of the MSPM0L1303SRGER?

The MSPM0L1303SRGER features an Arm Cortex-M0+ CPU with a maximum operating frequency of 32 MHz. It uses a 32-bit RISC architecture optimized for energy efficiency and real-time determinism. The device includes an internal 4–32 MHz oscillator with ±1.2% accuracy, eliminating the need for an external crystal. This enables compact, low-BOM designs while maintaining timing precision for control loops and communication protocols.

How many analog-to-digital converter (ADC) input channels does the MSPM0L1303SRGER support, and what is its resolution and speed?

The MSPM0L1303SRGER integrates a 12-bit analog-to-digital converter (ADC) capable of up to 1.68 million samples per second (Msps). In the 16-pin WQFN (RTR) package, it supports 9 external analog input channels (A0, A1, A2, A4, A5, A6, A7, plus two OPA outputs and COMP0_OUT). The ADC includes configurable internal voltage references (1.4 V or 2.5 V) and supports hardware-triggered conversions synchronized to timers or events.

Does the MSPM0L1303SRGER include operational amplifiers, and if so, what are their key electrical characteristics?

Yes, the MSPM0L1303SRGER includes two zero-drift, zero-crossover chopper operational amplifiers (OPA0 and OPA1). Key specifications include 0.5 µV/°C input offset drift, 6 pA input bias current, and integrated programmable gain (1× to 32×). Each OPA supports multiple input configurations (e.g., OPA0_IN0+, OPA0_IN0−, OPA0_IN1−) and can drive the ADC directly - enabling precision sensor signal conditioning without external op-amp stages.

What low-power modes are available on the MSPM0L1303SRGER, and what is the current consumption in STANDBY mode?

The MSPM0L1303SRGER supports four low-power modes: RUN, STOP, STANDBY, and SHUTDOWN. In STANDBY mode, it consumes just 1.0 µA while retaining full SRAM and register contents, keeping a 32-kHz 16-bit timer running, and enabling wake-up via GPIO or peripheral events within 3.2 µs. This makes it ideal for applications requiring periodic sensing with minimal quiescent current, such as wireless sensor nodes and battery-backed monitoring systems.

Which communication interfaces are supported by the MSPM0L1303SRGER, and do they operate in low-power modes?

The MSPM0L1303SRGER supports two UARTs (one with LIN/IrDA/DALI/Manchester support), two I²C interfaces (one FM+ capable at 1 Mbit/s), and one SPI (up to 16 Mbit/s). All three interface types retain functionality in STANDBY mode: UARTs and I²C can generate wake-up events from STOP, and I²C supports SMBus/PMBus protocols with STOP-mode wakeup. This enables always-on communication readiness without compromising system-level power budgets.
