8 MHz core — what it means for timing
The 8 MHz clock rate is the CPU's maximum operating frequency. For a 16-bit RISC core, that translates to roughly 8 MIPS.
Lifecycle and sourcing reality
The MSP430F155IRTDT carries an active lifecycle status, but the MSP430F155 base number is in the MSP430x1xx series which TI has been transitioning to newer families. 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.
