Enough to keep a segmented LCD updated, sample all 16 ADC channels at a few kHz, and handle UART/SPI/I²C traffic without a scheduler fight. ## Lifecycle reality — this is an EOL part The MSP430F6433IPZ carries an EOL-hot lifecycle status. TI has issued a last-time-buy notice; the window for factory orders is closing. New designs should not target this exact order code. ## Peripherals that matter for a retrofit The 16-channel 12-bit ADC covers most analog inputs on a control panel. DMA offloads the CPU for LCD refresh or ADC buffer transfers. I²C, SPI, UART, and IrDA are all on the connectivity list; LINbus is there if you are tying into an automotive or industrial LIN segment. Watchdog timer is standard.","metaTitle":"TI MSP430F6433IPZ 16-bit MCU, 20 MHz, 128 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F6433IPZ 16-bit MCU with MSP430 CPUXV2 core, 20 MHz, 128 KB Flash, 10 KB RAM, 74 I/O, industrial temp -40°C to 85°C.
