It translates SPI commands into USB transactions, so any microcontroller with a spare SPI port can act as a USB host or device without needing built-in USB MAC/PHY logic. The 32-TQFP (5x5) package keeps the footprint small for space-constrained designs like portable instruments, embedded terminals, or industrial panel interfaces. ## Lifecycle and compliance This part carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so it can be specified into new designs without near-term obsolescence risk.","metaTitle":"MAX3421EEHJ+T USB 2.0 Controller, 32-TQFP, SPI Interface","metaDescription":"MAX3421EEHJ+T USB 2.0 controller IC in 32-TQFP.
