The MSP430F6766IPZR: This is not an NRND or last-time-buy notice — production has ended, and the part is no longer available through authorized TI distribution channels.
What the MSP430F6766IPZR brings to a design
It carries 256KB of Flash program memory and 16KB of RAM, which is a comfortable footprint for complex metrology algorithms and communication stacks. The standout feature is the six independent 24-bit sigma-delta analog-to-digital converters — these are purpose-built for polyphase energy metering, power quality monitoring, and precision industrial measurement where simultaneous multi-channel acquisition is required. Connectivity options include I²C, IrDA, LINbus, SPI, and UART/USART interfaces, giving flexibility for sensor aggregation, display drivers, and fieldbus communication. The 62 general-purpose I/O pins and integrated LCD driver (via the peripheral set) make it suitable for metering front panels with local readout.
Finding a replacement path
Because the MSP430F6766IPZR is obsolete, the most practical route for existing designs is a pin-compatible sibling within the MSP430F6xx family. The MSP430F6766IZR shares the same base product number and 100-LQFP package — the suffix difference ('IPZR' vs 'IZR') typically indicates a packaging or temperature grade variant. For new designs, TI's MSP430FR6xx FRAM-based series offers a modern alternative with similar analog integration, though the package and pinout must be validated against the 100-LQFP footprint.
