Product details

Mixed-signal MCU with on-chip ADC and DAC

The Texas Instruments MSP430F156IRTDR is a 16-bit MSP430 CPU16 microcontroller clocked at 8 MHz, integrating 24 KB of Flash program memory and 1 KB of RAM. The device operates from a 1.8 V to 3.6 V supply and is rated over the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, remote telemetry, and portable instrumentation where low power and mixed-signal integration are required.

The MSP430F156IRTDR includes a brown-out detect and reset circuit, DMA controller, POR, PWM timer, and watchdog timer. Serial interfaces cover I²C, SPI, and UART/USART, supporting common sensor and actuator communication protocols. With 48 general-purpose I/O lines in a 64-VFQFN package (9x9 mm), the part provides sufficient pin count for mixed-signal control boards without requiring port expansion.

Brown-out detection and POR ensure reliable startup and operation under brownout conditions common in battery-powered or energy-harvesting designs.

Frequently asked questions

What is the exact operational temperature range of MSP430F156IRTDR?

The MSP430F156IRTDR is rated for -40°C to 85°C ambient operating temperature, covering industrial applications such as factory automation, outdoor telecom, and engine-bay monitoring.

What is the difference between MSP430F156IRTDR and MSP430F155IRTDR?

Both are 16-bit MSP430 MCUs with identical core, package, and temperature range. The MSP430F156IRTDR includes a 2-channel 12-bit DAC, while the MSP430F155IRTDR omits the DAC. For designs requiring analog output, the F156 is the correct choice; the F155 suits purely digital control applications.

What is MSP430F156IRTDR's listed speed?

The MSP430F156IRTDR is clocked at 8 MHz, which is sufficient for low-power mixed-signal control loops, sensor polling, and communication protocol handling in industrial and portable applications.
