The LCD driver supports segment displays up to 196 segments, so you can drive a local readout without an external display controller. The 62 GPIOs give plenty of room for tamper detection, relay control, and opto-isolated pulse outputs. Brown-out reset and POR are built in, so the supply supervisor count on the BOM stays at zero. Internal oscillator means one less external component, though a precision crystal is still advisable if the sigma-delta ADC needs tight line-frequency tracking. ## Package and rework considerations Housed in a 100-pin LQFP with a 14x14 mm body and 0.5 mm pitch. The exposed pad is on the bottom — it needs a thermal via stitch under the part to pull heat into the ground plane. It reflows fine with a standard profile, and the 0.5 mm pitch is inspectable under a microscope. MSL 3 out of the bag — bake before reflow if the moisture barrier pouch has been open past the floor-life window.","metaTitle":"MSP430F6746AIPZR 16-bit MCU, 25 MHz, 256 KB Flash, 100-LQFP","metaDescription":"TI MSP430F6746AIPZR 16-bit MCU with 25 MHz CPU, 256 KB Flash, 16 KB RAM, 4x24-bit ΣΔ ADC, LCD driver.
