Product details

Six 24-bit sigma-delta ADCs — the metering core

Its standout feature is the six independent 24-bit sigma-delta ADCs, purpose-built for polyphase energy metering and precision industrial measurement where simultaneous sampling of multiple voltage and current channels is required.

Peripheral set and connectivity

For system communication it supports I²C, IrDA, LINbus, SPI, and UART/USART interfaces. With 90 general-purpose I/O lines in a 128-LQFP package (20x14 mm body), this MCU can handle the parallel sensor inputs and display segments common in panel-mount instruments.

Temperature range and supply

The internal oscillator keeps BOM count low for applications that don't require an external crystal, though the clock tree supports external sources when tighter timing is needed.

Lifecycle and sourcing

Listed as Active by Texas Instruments — no end-of-life notification, no last-time-buy pressure.

Frequently asked questions

What is MSP430F67661AIPEU's listed speed?

The core runs at 25 MHz. That clock rate is sufficient for real-time polyphase metering algorithms and communication protocol handling without the overhead of a higher-speed ARM core.

What are alternatives to MSP430F67661AIPEU?

Within the MSP430F6xx family, pin-compatible variants differ mainly in Flash/RAM size and ADC count. The MSP430F67661AIPEU sits at the high end with 256 KB Flash and six 24-bit sigma-delta converters. Lower-density siblings (e.g., 128 KB Flash, fewer ADC channels) share the same 128-LQFP footprint and peripheral set, making them drop-in options for cost-reduced BOMs when the full ADC count or memory isn't needed.
