For a new design, look at the active MSP430FRxx FRAM series or the MSP430F5xx family for a pin-compatible path forward.
The integrated LCD controller drives segment displays directly, saving a separate driver IC and the associated board space. The 3-channel 16-bit sigma-delta ADC gives enough resolution for weigh-scale load cells, thermocouple linearization, or gas-sensor readouts without an external converter.
TI does not publish a direct pin-compatible drop-in for this NRND part. For a new design, consider the active MSP430FRxx FRAM series or MSP430F5xx family, which offer similar peripheral sets in compatible packages — check the specific pinout before swapping.
The core runs at 8 MHz — enough for real-time sensor polling and LCD updates without burning through the power budget.
It is part of the MSP430x4xx series, which is known for integrated LCD drivers and high-performance analog peripherals in a low-power 16-bit core.
Texas Instruments provides RoHS and REACH compliance data for this part. The 64-LQFP package is lead-free and meets the current environmental directives. Specific certificates are available on request with an RFQ.
