The 12-bit ADC with 12 analog inputs handles sensor conditioning without an external converter. DMA moves data between ADC, memory, and LCD without CPU intervention, keeping the 8 MHz core free for protocol handling and UI logic. ## Packaging and mounting Housed in an 80-lead LQFP (12x12 mm body), surface-mount. The 48 I/O lines give plenty of headroom for a parallel LCD data bus, keypad matrix, and sensor inputs in a single-layer routing board.","metaTitle":"Texas Instruments MSP430F439IPNR 16-bit MCU, 60KB Flash, 8MHz, 80-LQFP","metaDescription":"MSP430F439IPNR 16-bit MCU from TI, MSP430x4xx series, 60KB Flash, 2KB RAM, 8MHz, integrated LCD driver, 12-bit ADC, -40 to 85°C.
