Product details

16-bit MSP430 core at 8 MHz — what the speed and memory mean for your BOM

The MSP430A051IPM: It carries an 8-channel, 12-bit ADC, three serial interfaces (SPI, UART/USART), and 48 general-purpose I/O lines.

Memory sizing — 16 KB Flash and 512 B RAM

The 16 KB Flash (16K x 8 plus 256 bytes) and 512 x 8 RAM set the firmware and data-buffer ceiling.

The base product number is MSP430A051, and the device is part of the MSP430x1xx series, which shares a common architecture and toolchain across density options.
