It integrates a pre-driver configurable as three half-bridge outputs, making it a single-chip solution for sensorless or sensored field-oriented control in appliance-class drives. Communication with a host microcontroller runs over I2C, SPI, or RS-232 — the three interfaces share pins, so the firmware selects one protocol at board level. ## Lifecycle: obsolete — sourcing reality","metaTitle":"IRMCK343TY MCE™ Motor Controller, 64-LQFP, Obsolete","metaDescription":"IRMCK343TY MCE™ controller for AC synchronous motor commutation.
