Description
The Texas Instruments MSP430i204x, MSP430I203x and MSP430I202x microcontrollers (MCUs) are part of the MSP430™ Metrology and Monitoring portfolio. The architecture and integrated peripherals, combined with five extensive low-power modes, are optimized to achieve extended battery life in portable and battery-powered measurement applications. The devices feature a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the devices to wake up from low-power modes to active mode in less than 5 µs.
The MSP430i204x MCUs include four high-performance 24-bit sigma-delta ADCs, two eUSCIs (one eUSCI_A module and one eUSCI_B module), two 16-bit timers, a hardware multiplier, and up to 16 I/O pins.
The MSP430I203x MCUs include three high-performance 24-bit sigma-delta ADCs, two eUSCIs (one eUSCI_A module and one eUSCI_B module), two 16-bit timers, a hardware multiplier, and up to 16 I/O pins.
The MSP430I202x MCUs include two high-performance 24-bit sigma-delta ADCs, two eUSCIs (one eUSCI_A module and one eUSCI_B module), two 16-bit timers, a hardware multiplier, and up to 16 I/O pins.
Typical applications for these devices include energy measurement, analog and digital sensor systems, LED lighting, digital power supplies, motor controls, remote controls, thermostats, digital timers, and hand-held meters.
The MSP430i204x, MSP430I203x and MSP430I202x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits include the EVM430-I2040S evaluation module (EVM) for metering and the MSP-TS430RHB32A 100-pin target development board. The Energy Measurement Design Center for MSP430 MCUs is provided as a rapid development tool that enables energy measurement on these devices. TI also provides free MSP430Ware™ software, which is available as a component of Code Composer Studio™ IDE desktop and cloud versions within TI Resource Explorer. The MSP430 MCUs are also supported by extensive online collateral, training, and online support through the TI E2E™ support forums.
