MSPM0G3507SPTR

The MSPM0G350x microcontroller (MCU) belongs to the MSP highly integrated ultra-low-power 32-bit MCU series. This MCU series is based on an enhanced Arm Cortex-M0+ 32-bit core platform and can operate at a maximum frequency of 80MHz. These low-cost MCUs offer high-performance analog peripheral integration, support an operating temperature range of -40°C to 125°C, and operate at a supply voltage of 1.62 V to 3.6 V. The MSPM0G350x devices provide up to 128KB of embedded flash program memory with built-in error correction code (ECC) and up to 32KB of SRAM with ECC and hardware parity options. These MCUs also include a memory protection unit, a 7-channel DMA, a math accelerator, and various high-performance analog peripherals, such as two 12-bit 4MSPS ADCs, a configurable internal shared voltage reference, a 12-bit 1Msps DAC, three high-speed comparators with built-in reference DACs, two zero-drift zero-crossing operational amplifiers with programmable gain, and a general-purpose amplifier. These devices also offer intelligent digital peripherals, such as two 16-bit advanced control timers, five general-purpose timers (including one 16-bit general-purpose timer for the QEI interface, two 16-bit general-purpose timers for standby mode, and one 32-bit general-purpose timer), two windowed watchdog timers, and an RTC with alarm and calendar modes. These devices provide data integrity and encryption peripherals (AES, CRC, TRNG) and enhanced communication interfaces (four UARTs, two I2Cs, two SPIs, and CAN 2.0/FD). The TI MSPM0 series of low-power MCUs includes devices with different levels of analog and digital integration, allowing customers to find an MCU that meets their engineering requirements. The MSPM0 MCU platform combines the Arm Cortex-M0+ platform with an ultra-low-power overall system architecture, enabling system designers to improve performance while reducing energy consumption. The MSPM0G350x MCUs are supported by a wide range of hardware and software ecosystems, and come with reference designs and code examples to help you quickly start your design. The development kits include purchasable LaunchPads. TI also offers a free MSP software development kit (SDK), which is available in the TI ResourceExplorer as a component of the Code Composer Studio IDE for both desktop and cloud versions. The MSPM0 MCUs also provide extensive online supporting materials and training through the MSP Academy, and offer online support through the TI E2E support forum.
