Product details

The 8 MHz clock rate is the CPU's maximum operating frequency. For a 16-bit RISC core, that translates to roughly 8 MIPS.

No official EOL notice has been issued for this specific order code, but the part is not a current-generation flagship. Sourcing is through independent distribution; we quote to order against an RFQ. For long-term production, consider pin-compatible alternatives within the MSP430F2xx or MSP430G2xx series — those are active and have wider availability. No official second-source cross-reference is listed.

Integrated ADC and DAC — BOM savings

The 12-bit ADC with 8 multiplexed channels and the dual 12-bit DAC eliminate the need for external analog front-end components in many sensor and control applications.

Frequently asked questions

Is MSP430F155IRTDT obsolete?

No, the MSP430F155IRTDT is listed as active in production. No end-of-life notice has been issued for this specific order code. However, the MSP430x1xx series is a mature family, so buyers should monitor TI's PCN notifications for any future phase-out.

What is the supply voltage and temperature range for MSP430F155IRTDT?

The operating supply range is 1.8 V to 3.6 V, and the temperature grade is -40°C to 85°C (industrial).

What package does MSP430F155IRTDT come in?

It is supplied in a 64-VFQFN exposed-pad package (9x9 mm body), surface-mount.

What is the closest pin-compatible alternative to MSP430F155IRTDT?

No official pin-compatible cross-reference is listed. Within the MSP430x1xx family, parts like the MSP430F147 or MSP430F149 share the same 64-pin VQFN footprint and peripheral set, but verify the exact memory and ADC configuration against your firmware requirements.

What is the core speed of MSP430F155IRTDT?

The CPU runs at 8 MHz maximum, delivering roughly 8 MIPS for a 16-bit RISC core.
