Product details

Six 16-bit ADCs — the reason this MCU exists

Its headline feature is six independent 16-bit sigma-delta ADCs (A/D 6x16b) — that is the peripheral that separates it from general-purpose MSP430 parts.

56 KB Flash — firmware budget for metering and comms

The 56 KB Flash (56K x 8) is the code-storage ceiling. For a three-phase energy meter with harmonic analysis, LCD driver, and UART/I²C/SPI protocol handling, that fills up fast. The 4K x 8 RAM is modest — expect to use the DMA and the hardware multiplier to keep the ADC data pipeline moving without CPU intervention.

The 100-LQFP package (14x14 mm) with 72 I/O gives plenty of pins for segmented LCD glass, external FRAM, and isolated RS-485 transceivers.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F47126IPZR?

Within the MSP430F471xx family, the Flash and RAM density options vary. The MSP430F47126 is the base part; higher-density siblings like the MSP430F47127 (64 KB Flash) or MSP430F47133 (92 KB Flash) are pin-compatible in the same 100-LQFP footprint. Check the specific memory and ADC channel count against your firmware size before substituting.
