The 256 KB of program Flash and 16K x 8 of RAM provide enough headroom for the metrology algorithms, calibration tables, and communication stacks without forcing an external memory. The 100-pin LQFP package brings out 62 I/O lines alongside the dedicated analog channels, so you can keep the signal chain on one die. ## Active lifecycle — no end-of-life clock ticking For a BOM line that sources a metrology-grade MCU, this avoids the scramble of a forced redesign mid-production. ## What the 24-bit ADC array means for system architecture Six independent 24-bit sigma-delta converters let you sample multiple voltage and current phases simultaneously — three-phase power metering with neutral sensing fits without external multiplexing. The 24-bit resolution delivers the dynamic range needed for Class 0.2 energy meters, where the effective number of bits at the line frequency determines the accuracy floor. The on-chip brown-out detect and POR circuits keep the ADC references stable during supply transients, which matters when the calibration constants live in Flash and a glitch corrupts the metrology baseline.","metaTitle":"Texas Instruments MSP430F6766IPZ 16-bit MCU, 25MHz","metaDescription":"MSP430F6766IPZ 16-bit MCU with 25MHz CPUXV2 core, 256KB Flash, 16Kx8 RAM, and six 24-bit sigma-delta ADCs.

At mains frequency (50/60 Hz) the effective resolution is primarily limited by the on-chip voltage reference stability and the layout noise floor, not the converter itself. For a typical polyphase meter design, the ADC path supports Class 0.2 accuracy with proper external anti-aliasing and a clean analog ground plane."},{"question":"What is the closest pin-compatible alternative to the MSP430F6766IPZ?","answer":"Within the MSP430F6xx series, pin-compatible variants differ primarily in Flash density and ADC channel count. The MSP430F6779IPZ offers a larger memory option, while the MSP430F67641IPZ provides a reduced peripheral set.
