It carries 128 KB of Flash program memory and 8 KB of RAM, with a peripheral set including a 3-channel 24-bit sigma-delta ADC, an 8-channel 10-bit SAR ADC, DMA, LCD driver, and a full complement of serial interfaces (I²C, SPI, UART, IrDA). The 100-LQFP package exposes 72 general-purpose I/O lines. Supply range is 1.8 V to 3.6 V, and the operating temperature covers -40°C to 85°C, making it suitable for industrial and energy-metering environments where the three sigma-delta converters handle precision current and voltage sensing. ## Three 24-bit sigma-delta ADCs — the metrology anchor The three independent 24-bit sigma-delta converters are the distinguishing feature of this MSP430F6xx variant. They allow simultaneous sampling of voltage and two current channels in a single-phase energy meter, or three-phase voltage/current in a polyphase design, without external analog front-end components. The on-chip 8x10b SAR ADC handles auxiliary measurements (temperature, neutral current) on the same die.","metaTitle":"MSP430F67641IPZ 16-bit MCU, 25 MHz, 128KB Flash, 3x24b Σ-Δ ADC","metaDescription":"Texas Instruments MSP430F67641IPZ 16-bit MCU, 25 MHz, 128KB Flash, 8KB RAM, 3x24b sigma-delta ADC, 8x10b SAR ADC, 72 I/O, -40°C to 85°C, 100-LQFP.
