The 512 B RAM is tight but workable for a single-phase meter: it stores instantaneous power values, accumulated energy registers, and a small UART buffer. If the application adds data logging or advanced tamper detection, consider moving to a higher-density sibling in the MSP430FE42x family. The Flash is in-system programmable via SPI or UART, supporting field firmware updates. ## Dual 16-bit sigma-delta ADC — the energy measurement engine The two 16-bit sigma-delta ADCs sample voltage and current simultaneously, eliminating phase error. This supports active-power computation with digital offset and gain correction. The differential ADC inputs accept signals from current transformers or shunt resistors.","metaTitle":"Texas Instruments MSP430FE4242IPMR 16-bit MCU, 8 MHz, 12 KB Flash, 64-LQFP","metaDescription":"MSP430FE4242IPMR 16-bit MCU from TI, 8 MHz core, 12 KB Flash, 512 B RAM, dual 16-bit sigma-delta ADC, -40 to 85°C, 64-LQFP.
