For engineers reviewing the MSPM0L1306TDGS28R datasheet, MSPM0L1306TDGS28R pinout, MSPM0L1306TDGS28R application, or MSPM0L1306TDGS28R equivalent, key selection criteria include its 28-pin VSSOP package, –40°C to 125°C extended temperature rating, ultra-low standby current (1.0 µA), programmable analog interconnect, and dual UART/I²C/SPI interfaces supporting LIN, SMBus, and PMBus protocols.

Technical Context

The MSPM0L1306TDGS28R implements an enhanced Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and integrates a dedicated peripheral bus architecture separating CPU, DMA, and ultra-low-power (ULPCLK) domains for deterministic timing across RUN/STOP/STANDBY modes.

Analog subsystem integration includes configurable VREF (1.4 V or 2.5 V), hardware-programmable gain (1–32×) for OPA outputs, direct routing between ADC, COMP, GPAMP, and DAC, and a high-speed comparator with 32-ns propagation delay and built-in 8-bit reference DAC.

FAQ

What is the maximum operating frequency and core architecture of the MSPM0L1306TDGS28R?

The MSPM0L1306TDGS28R features an Arm Cortex-M0+ CPU core with a maximum operating frequency of 32 MHz. This architecture delivers efficient 32-bit processing with low power consumption, and the device achieves 71 µA/MHz in RUN mode per CoreMark. Its SYSOSC provides ±1.2% accuracy across temperature, eliminating need for external crystals. The MSPM0L1306TDGS28R's performance and efficiency make it suitable for real-time control tasks in constrained environments.

How many analog input channels does the MSPM0L1306TDGS28R support, and what ADC resolution and speed does it offer?

The MSPM0L1306TDGS28R supports up to 10 external analog input channels via its 12-bit successive-approximation ADC, which operates at up to 1.68 million samples per second. It includes configurable internal voltage references (1.4 V or 2.5 V) and supports both single-ended and differential acquisition modes. The ADC integrates directly with the OPA and COMP peripherals through hardware routing, enabling synchronized analog signal processing without software overhead - a capability confirmed in the MSPM0L130x technical reference manual.

What ultra-low-power modes are available on the MSPM0L1306TDGS28R, and what are their typical current draws?

The MSPM0L1306TDGS28R offers four low-power modes: RUN (71 µA/MHz), STOP (151 µA at 4 MHz or 44 µA at 32 kHz), STANDBY (1.0 µA with 32-kHz timer active and full SRAM retention), and SHUTDOWN (61 nA with IO wakeup). In STANDBY mode, the device wakes in 3.2 µs to 32 MHz, enabling rapid response to events while maintaining decade-scale battery life. These values are measured per TI SLASEX0D datasheet Section 7.5 and validated across the –40°C to 125°C range.

Does the MSPM0L1306TDGS28R include integrated operational amplifiers, and what are their key specifications?

Yes, the MSPM0L1306TDGS28R integrates two zero-drift, zero-crossover chopper operational amplifiers (OPA0 and OPA1) with 0.5-µV/°C input offset drift and 6-pA input bias current. Each supports programmable gain from 1× to 32× and features dedicated analog input pins (e.g., OPA0_IN0+, OPA0_IN0−, OPA1_IN0+). These OPAs are fully routable to the ADC, COMP, and DAC, enabling closed-loop analog signal chains without external components - as documented in the MSPM0L130x family datasheet Section 1.1.

What communication interfaces are supported by the MSPM0L1306TDGS28R, and which protocols do they enable?

The MSPM0L1306TDGS28R supports two UARTs (one with LIN, IrDA, DALI, Smart Card, Manchester), two I²C interfaces (one FM+ at 1 Mbit/s, both with SMBus/PMBus), and one SPI (up to 16 Mbit/s). These interfaces operate in STANDBY mode with wakeup capability. Protocol support includes LIN physical layer compliance, SMBus alert response, PMBus command sets, and Manchester encoding - all verified in TI's MSPM0L130x Technical Reference Manual and SLASEX0D datasheet Sections 1.1 and 7.18–7.20.
