16MHz MSP430 core with 7-channel delta-sigma ADC
The MSP430F47167IPZ is a 16-bit microcontroller from the MSP430x4xx series, built around the MSP430 CPU16 core clocked at 16MHz. Its headline feature is the 7×16-bit delta-sigma ADC array — a dedicated measurement front-end that samples multiple voltage and current channels simultaneously, which is the defining requirement for polyphase energy metering and power-quality monitoring designs. On-chip memory comprises 92KB of FLASH program memory and 4KB of RAM, providing enough firmware space for the metrology algorithms and a data buffer for the ADC results before the DMA engine moves them to main memory.
Peripheral set for standalone metering nodes
The integrated LCD controller drives segment displays directly, eliminating the need for a separate display driver chip in utility-meter and instrument-panel applications. The DMA controller offloads ADC result transfers from the CPU, preserving the 16MHz throughput for the core metrology loop. Connectivity options include I²C, SPI, UART/USART, IrDA, and LINbus — covering isolated sensor links (I²C/SPI to external AFEs or EEPROM), RS-485 gateway interfaces (UART), and automotive-grade LIN communication for sub-metering nodes in vehicle charging stations.
Packaged in a 100-LQFP with a 14×14mm body (0.5mm pitch), the footprint is a standard JEDEC outline shared across the MSP430x4xx family. A board designed for this package can accept pin-compatible siblings with different memory or ADC configurations without a layout change.
Active lifecycle — sourcing posture
The base product number MSP430F47167 is the design-in anchor; the IPZ suffix denotes the 100-LQFP tray package.
