The MSP430F122IPW: Supply range is 1.8 V to 3.6 V. The slope A/D is a ratiometric measurement block for thermistors or pot feedback.
The MSP430F122IPW is listed as Active. For volume or scheduled BOM requirements, this part is quoted to order against an RFQ.
The MSP430F122IPW is a 16-bit MCU with an 8 MHz MSP430 CPU16 core, 4 KB Flash program memory, 256 bytes of RAM, 22 I/O lines, SPI and UART/USART interfaces, a slope A/D converter, and an internal oscillator. It operates from 1.8 V to 3.6 V over -40 to 85 °C and comes in a 28-TSSOP package.
The MSP430F123IPW is a higher-density variant in the same family, offering 8 KB of Flash and 256 bytes of RAM versus the 4 KB Flash on the MSP430F122IPW. Both share the same 28-TSSOP package, 8 MHz core, peripheral set, and pinout, so the upgrade is a firmware-capacity decision with no board layout change.
The MSP430F122IPW is supplied in a 28-TSSOP package (0.173", 4.40 mm width), surface-mount, on tube packaging.
