Product details

What this MSP430 brings to a low-power design

It integrates an 8-channel 10-bit ADC, SPI and UART/USART serial interfaces, and 22 general-purpose I/O lines. The 32-VQFN (5x5 mm) package with exposed pad helps thermal management in compact layouts.

Memory and peripheral budget — what fits in 4 KB Flash and 256 B RAM

With 4 KB of Flash and 256 bytes of RAM, this part targets control loops, sensor readout, and simple communication protocols. The brown-out reset and power-on reset peripherals keep the system reliable during supply transients.
