The parallel interface connects directly to GPIO pins on a host MCU; no SPI or I²C bus allocation is needed, which simplifies the firmware layer for simple on/off and speed-step control. RoHS3 compliance is confirmed on the manufacturer's status, so the part passes EU and UKCA material restrictions without a waiver.","metaTitle":"Microchip TC649VPA Fan Controller, 3V-5.5V, 8-DIP","metaDescription":"Active Microchip TC649VPA BLDC fan speed controller, 3V-5.5V supply, 8-PDIP through-hole.
