Product details
Frequently asked questions
What are the key specifications of MSP430F122IPW?
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.
What is the difference between MSP430F122IPW and MSP430F123IPW?
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.
What package is MSP430F122IPW?
The MSP430F122IPW is supplied in a 28-TSSOP package (0.173", 4.40 mm width), surface-mount, on tube packaging.
