MSP430F67461AIPZ — precision measurement MCU with integrated LCD and sigma-delta ADC
These features target smart metering, instrumentation, and industrial sensor nodes where both high-accuracy analog conversion and a local display are needed without external components.
Peripheral set for metering and instrumentation
The four 24-bit sigma-delta ADCs are the standout feature — they enable simultaneous sampling of multiple voltage or current channels in polyphase energy meters, with enough resolution to capture harmonic content. The LCD controller drives up to 196 segments directly, eliminating a separate display driver IC and reducing BOM count. The brown-out detect and POR provide reliable power-on sequencing, critical for unsupervised field equipment that may see supply glitches. Connectivity options include I²C, SPI, UART/USART, LIN, and IrDA, covering both wired sensor buses and serial communication with a host processor or radio module. With 62 general-purpose I/O pins in the 100-LQFP package, there is enough headroom for external memory, keypads, or additional sensor interfaces without a port expander.
Package and footprint
Housed in a 100-pin LQFP with a 14x14 mm body, this is a standard surface-mount package with 0.5 mm pitch. The exposed pad (if present on this variant) should be stitched to ground with thermal vias for best heat transfer, though the 25 MHz core and low-power MSP430 architecture keep dissipation modest.
