7x24-bit sigma-delta ADC — the headline reason for this part
What sets it apart from the general-purpose MSP430 family is the integrated 7x24-bit sigma-delta ADC — a peripheral array designed for polyphase energy metering, precision instrumentation, and multi-channel sensor acquisition where simultaneous high-resolution sampling matters.
The 128-LQFP package (20x14 mm body) is a hand-solderable fine-pitch QFP; no BGA rework required for prototyping or low-volume production.
Peripheral set and connectivity
Beyond the ADC, the peripheral list includes a DMA controller for moving conversion results without CPU intervention, an LCD driver for direct segment-display drive, a brown-out detect and POR, PWM timers, and a watchdog. Communication interfaces cover I²C, SPI, UART/USART, LINbus, and IrDA — enough to talk to an external radio module, a serial EEPROM, or a Modbus transceiver. With 90 GPIOs, most of these interfaces can be placed on multiple pin options, easing PCB routing.
Lifecycle — active, no LTB pressure
The base product number MSP430F67781 covers the whole family; the AIPEUR suffix denotes the industrial temperature range and the Tape & Reel shipping format.
