What this MCU brings to the board
The Texas Instruments MSP430F6749AIPZ is a 16-bit MCU built around the MSP430 CPUXV2 core running at 25 MHz, with 512 KB of Flash and 32 KB of RAM. It carries four 24-bit sigma-delta ADCs plus an 8-channel 10-bit SAR ADC, an LCD controller, and 62 GPIOs. This part is aimed at polyphase energy metering and precision measurement applications where multiple simultaneous high-resolution analog inputs are needed.
Temperature grade and environment
Rated for -40°C to 85°C, it fits industrial environments like outdoor metering enclosures, factory-floor instrumentation, and utility-grade power monitors where extended temperature swings are routine.
Lifecycle status — plan ahead
This part is flagged as end-of-life (EOL). For new designs, look at the MSP430F6xx family's active successors or consider an MSP430FRxx FRAM-based alternative if non-volatile memory endurance matters. For existing BOMs, this part remains available through independent distribution on a quoted-to-order basis — we can source it against an RFQ, but lead times and pricing will reflect the EOL status.
