The Texas Instruments MSP430F6769AIPZ is a 16-bit microcontroller with a 25 MHz core, 512 KB Flash, 32 KB RAM, and peripherals including a 6-channel 24-bit sigma-delta ADC, LCD driver, DMA, and serial interfaces (I²C, SPI, UART/USART, IrDA, LIN). It is housed in a 100-pin LQFP and rated for -40°C to 85°C.
Six 24-bit sigma-delta ADCs — the metrology core
The six 24-bit sigma-delta converters enable simultaneous voltage and current sensing on three phases, plus neutral.
25 MHz CPUXV2 — timing headroom for real-time loops
The 25 MHz core provides margin to run the metrology algorithm, LCD refresh, and communication stack within a single interrupt cycle. The 16-bit word width is efficient for accumulator-heavy math.
Industrial temperature grade and supply range
Rated for -40°C to 85°C operation with a supply range of 1.8 V to 3.6 V, the MSP430F6769AIPZ fits designs that must survive cold-start in outdoor enclosures or hot factory-floor cabinets. The brown-out detect and POR ensure deterministic reset behaviour across the full voltage and temperature envelope.
Lifecycle and sourcing
This part carries an active lifecycle status from Texas Instruments, so no end-of-life notice is pending. It is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
