FAQ

What is the maximum operating frequency and core architecture of the MSPM0L1304SRGER?

The MSPM0L1304SRGER features an Arm Cortex-M0+ 32-bit RISC core with a maximum operating frequency of 32 MHz. This architecture delivers efficient Thumb-2 instruction execution, low interrupt latency, and deterministic real-time behavior - making it suitable for time-critical control tasks in power delivery and sensor systems. The MSPM0L1304SRGER achieves 71 µA/MHz in RUN mode, confirming its optimization for energy-sensitive applications.

Does the MSPM0L1304SRGER support hardware debug, and what interface is used?

Yes, the MSPM0L1304SRGER supports full hardware debug and programming via a 2-pin Serial Wire Debug (SWD) interface using SWCLK and SWDIO pins. This interface enables breakpoints, register inspection, real-time variable monitoring, and flash programming without requiring additional pins or protocol overhead. The MSPM0L1304SRGER integrates SWD support directly into its debug module, ensuring compatibility with standard TI tools like Code Composer Studio™ and third-party JTAG/SWD debuggers.

What analog peripherals are integrated into the MSPM0L1304SRGER, and how many ADC input channels are available?

The MSPM0L1304SRGER integrates a 12-bit, 1.68-Msps ADC with up to 10 external analog input channels (A0–A9), two zero-drift chopper operational amplifiers (OPA0 and OPA1), one general-purpose amplifier (GPAMP), one high-speed comparator (COMP0) with integrated 8-bit reference DAC, and an on-chip temperature sensor. These peripherals are interconnected via a programmable analog mux, allowing flexible signal routing - for example, OPA outputs can feed ADC inputs or COMP references without external components.

What are the lowest power consumption modes supported by the MSPM0L1304SRGER, and what features remain active in each?

The MSPM0L1304SRGER supports SHUTDOWN mode (61 nA with IO wakeup), STANDBY mode (1.0 µA with 32-kHz 16-bit timer running, full SRAM/register retention, and 3.2 µs wakeup), STOP mode (44 µA at 32 kHz), and RUN mode (71 µA/MHz). In STANDBY, all peripherals except the 32-kHz timer are gated, but GPIOs retain wake capability, and the ADC, OPAs, and COMP can be configured for autonomous low-power conversions triggered by events - enabling responsive yet frugal operation.

Is the MSPM0L1304SRGER pin-compatible with other members of the MSPM0L130x family, and what package does it use?

Yes, the MSPM0L1304SRGER uses the 32-pin VQFN (RHB) package and shares identical pinout and electrical characteristics with other RHB-package variants in the MSPM0L130x family, including MSPM0L1305SRGER and MSPM0L1306SRGER. This allows direct PCB reuse across flash/RAM variants - simplifying design scalability and inventory management. All RHB devices support the same 28 GPIOs, analog input mapping, and peripheral pin assignments defined in the functional block diagram and pin attribute tables.
