Maxim MAX3420E USB Peripheral Controller with SPI Interface Datasheet
The MAX3420E is a full‑speed USB peripheral controller that implements the USB 2.0 specification via an SPI‑based interface. It provides a built‑in full‑speed transceiver with +15 kV ESD protection, programmable USB connect/disconnect, and internal level translators allowing operation from 1.71 V to 3.6 V system voltage. The device includes four general‑purpose inputs and four general‑purpose outputs, endpoint FIFOs, and an internal serial‑interface engine that handles low‑level USB protocol details.
The datasheet supplies a functional diagram, pin‑out tables, register map, absolute maximum ratings, and electrical characteristics. It also lists the two available packages—24‑pin TQFN (4 mm × 4 mm) and 32‑pin LQFP (7 mm × 7 mm)—and provides ordering information, revision history, and contact details for Maxim Integrated Products.
