Texas Instruments MSPM0L1105TRGER

Overview

MSPM0L1105TRGER from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC with 10 external channels, and integrated GPAMP and temperature sensor. It targets ultra-low-power battery-powered systems such as smart metering and portable medical devices.

For engineers reviewing the MSPM0L1105TRGER datasheet, MSPM0L1105TRGER pinout, MSPM0L1105TRGER application, or MSPM0L1105TRGER equivalent, key selection considerations include its 32-pin VQFN (RHB) package, –40°C to 105°C extended temperature rating, 1.62–3.6 V supply range, STANDBY mode consuming only 1.0 µA with full SRAM retention, and dual UARTs supporting LIN and low-power wakeup.

Technical Context

The MSPM0L1105TRGER implements an Arm Cortex-M0+ core with on-chip 4–32 MHz SYSOSC (±1.2% accuracy) eliminating external crystals, and a 32-kHz LFOSC (±3%) for low-power timing. Its power management unit supports four distinct low-power modes-RUN, STOP, STANDBY, and SHUTDOWN-with sub-µA retention and 3.2 µs wakeup from STANDBY using the 32 MHz clock.

Digital peripherals include a 3-channel DMA, four 16-bit timers (8 PWM channels total), windowed watchdog, and event fabric for inter-peripheral signaling. Analog integration comprises one configurable 1.4-V/2.5-V internal VREF, GPAMP with dedicated IN+/IN−/OUT pins, and temperature sensor-all accessible via shared GPIO pins under IOMUX control.

FAQ

What is the maximum ADC sampling rate supported by the MSPM0L1105TRGER?

The MSPM0L1105TRGER features a 12-bit analog-to-digital converter with a maximum sampling rate of 1.68 million samples per second (Msps). This specification is confirmed in the device's datasheet Section 7.12 and applies directly to the MSPM0L1105TRGER across its full operating voltage and temperature range. The ADC supports up to 10 external analog input channels and uses either the internal 1.4-V or 2.5-V reference voltage.

Does the MSPM0L1105TRGER support LIN bus communication?

Yes, the MSPM0L1105TRGER supports LIN bus communication through UART0, which is explicitly documented in the "Enhanced communication interfaces" section of the datasheet. UART0 includes hardware-level LIN protocol support, enabling direct connection to LIN transceivers without additional protocol translation. This capability is native to the MSPM0L1105TRGER and does not require external co-processors or firmware emulation.

What package type and pin count does the MSPM0L1105TRGER use?

The MSPM0L1105TRGER uses a 32-pin VQFN package with the RHB suffix, measuring 5 mm × 5 mm and featuring an exposed thermal pad. This package is confirmed in the Device Comparison table (Table 5-1) and Pin Configuration section (Figure 6-2) of the official datasheet. The RHB variant is the only 32-pin option for the MSPM0L1105 family and is distinct from the 28-pin DGS, 24-pin RGE, 20-pin DGS, and 16-pin RTR/DYY variants.

Can the MSPM0L1105TRGER operate across the full industrial temperature range?

Yes, the MSPM0L1105TRGER is qualified for operation from –40°C to +105°C, as stated in the "Operating characteristics" section and confirmed in Table 5-1 under the QUAL column (T grade). This extended temperature rating is guaranteed for all specified electrical parameters and applies to the RHB package variant. No derating or special thermal design is required within this range.

How many general-purpose timers does the MSPM0L1105TRGER include, and what PWM capability do they provide?

The MSPM0L1105TRGER includes four 16-bit general-purpose timers (TIMG0, TIMG1, TIMG2, TIMG4), each with two capture/compare registers, supporting a total of eight independent PWM channels. This configuration is documented in the "Intelligent digital peripherals" feature list and verified in the functional block diagram. All timers retain functionality in STANDBY mode, enabling low-power waveform generation for LED dimming or motor control.
