The LCD driver is integrated — no external segment controller needed for a character or simple graphic display. Housed in a 100-LQFP (14x14 mm) surface-mount package. Internal oscillator eliminates the external crystal for the main clock — one less BOM line. The 16-bit MSP430 CPU16 core draws low active current at 8 MHz, and the multiple low-power modes (LPM0–LPM4) let the firmware drop into microamp sleep between measurement cycles.","metaTitle":"MSP430F4491IPZR 16-bit MCU, 60KB Flash, 8MHz, 100-LQFP","metaDescription":"Texas Instruments MSP430F4491IPZR 16-bit MCU, 8MHz, 60KB Flash, 2K RAM, 48 I/O, -40 to 85°C, 100-LQFP.
