The CPUXV2 16-bit core runs at 25 MHz, delivering roughly 25 MIPS at the same clock — the limiting factor for throughput is the Flash wait-state profile, not the core itself, so the effective instruction rate depends on the code alignment and the prefetch buffer hit rate. ## 80-LQFP with 52 I/O — board integration and supply rail flexibility The 52 general-purpose I/O lines cover parallel LCD data buses, keypad scanning, and serial interface muxing without port sharing.","metaTitle":"MSP430F6721IPNR Texas Instruments MCU, 25MHz, 32KB Flash","metaDescription":"Texas Instruments MSP430F6721IPNR 16-bit MCU, 25MHz CPUXV2 core, 32KB Flash, 2Kx8 RAM, dual 24-bit SD ADC, 80-LQFP.

This is the same architecture used across the MSP430F6xx series, so code compiled for the CPUXV2 is binary-compatible within the family — no recompile needed when moving between F6xx variants with the same memory map."},{"question":"Does the MSP430F6721IPNR have on-chip ADCs for precision measurement?","answer":"Yes — two 24-bit sigma-delta ADCs and five 10-bit SAR converters are integrated. The 24-bit channels are the primary analog front-end for energy metering or load-cell readout; the 10-bit channels handle general-purpose analog inputs like potentiometers or thermistors."},{"question":"What compliance documentation does Texas Instruments provide for the MSP430F6721IPNR?","answer":"The part is ROHS3 compliant per TI's material declaration. No UL or IEC certification is listed in the standard product documentation — the MCU is a commercial/industrial component, not a safety-certified device.
