The MSP430F5435IPN: TI has flagged this variant for phase-out. Existing production runs and stocked units are still available through independent distribution.
This MCU packs I²C, SPI, UART/USART, LIN, and IrDA serial interfaces. The 16-channel, 12-bit ADC samples at rates suitable for slow-to-moderate analog signals.
Housed in an 80-pin LQFP (12x12 mm body), surface-mount only.
TI has flagged it for phase-out, but units are still available through independent distribution. For new designs, the pin-compatible MSP430F5438IPN (256 KB Flash) is the safer choice.
The MSP430F5438IPN is the closest pin-compatible upgrade — same 80-LQFP footprint, same core and peripherals, but with 256 KB Flash instead of 192 KB. Firmware migration is straightforward; the extra Flash headroom may even simplify your code.
