The 16 KB of program Flash and 1 KB of RAM are sized for the firmware that runs the metrology algorithms and communication stack, not for general-purpose application code. The 16.384 MHz clock is not arbitrary — it's chosen to synchronise with the sigma-delta modulator sampling rate, giving clean decimation filter output at 50 Hz and 60 Hz line frequencies. If you're evaluating this for a non-metrology role, the 16-bit core with 12 I/O and the standard MSP430 peripheral set (I²C, SPI, UART, IrDA, SCI) still works, but the real value is in the ADC front-end. This matters for outdoor telecom cabinets, motor drives with internal heating, and factory-floor sensor nodes that see thermal cycling. The supplier device package is 28-TSSOP, same as the package/case designation. No exposed thermal pad to worry about — the 28-TSSOP is a standard non-paddle leadframe package, so your standard TSSOP-28 land pattern is correct.","metaTitle":"TI MSP430I2040TPWR 16-bit MCU, 16KB Flash, 4x24b SD ADC","metaDescription":"Texas Instruments MSP430I2040TPWR 16-bit MCU with 16KB Flash, 1KB RAM, 4x24-bit sigma-delta ADC, 16.384 MHz CPU16 core.
