MSPM0H3216SPTR

The MSPM0H321x microcontrollers (MCUs) are part of the MSP highly integrated 5V power supply and 32-bit MCU family, based on an enhanced Arm® Cortex®-M0+ core platform operating at up to 32MHz. These low-cost MCUs offer high-performance analog peripheral integration, support an operating temperature range of -40℃ to 125℃, and operate from a supply voltage of 4.5V to 5.5V. The MSPM0H321x devices provide up to 64KB of embedded Flash program memory and 8KB of SRAM. These MCUs include a high-speed on-chip oscillator with accuracy of -2.1% to 1.6%, eliminating the need for an external crystal. These MCUs include a 3-channel DMA, CRC-16 accelerator, and various high-performance analog peripherals such as a 12-bit 1.6Msps ADC using VDD as the voltage reference and an on-chip temperature sensor. These devices offer intelligent digital peripherals, including one 16-bit advanced timer, four 16-bit general-purpose timers, one windowed watchdog timer, one independent watchdog timer, and one real-time clock (RTC). These devices also provide a variety of communication peripherals, including three UARTs, one SPI, and two I2Cs, with protocol support for LIN, IrDA, DALI, Manchester, Smart Card, SMBus, and PMBus. The MSPM0 family of low-power MCUs includes devices with varying levels of analog and digital integration to meet diverse engineering requirements. The architecture incorporates multiple low-power modes optimized to extend battery life in portable measurement applications. The MSPM0H321x MCUs are supported by a broad hardware and software ecosystem, with reference designs and code examples for rapid design start. Development kits include LaunchPad™ kits available for purchase and design files for target socket boards. TI offers a free MSP Software Development Kit (SDK), available as a component of both the desktop and cloud versions of the Code Composer Studio™ IDE in TI Resource Explorer. MSPM0 MCUs also provide extensive online companion materials and training through MSP Academy, along with online support via the TI E2E™ support forum.
