It handles all USB protocol and transaction management, offloading the host MCU from low-level USB timing. The 3V to 3.6V supply range and 15 mA supply current make it a fit for 3.3V logic systems where USB connectivity is needed without a dedicated USB-capable MCU. Typical applications include adding USB device capability to embedded systems, industrial instruments, and legacy equipment retrofits. ## Industrial temperature range and package Rated for -40°C to 85°C operation, the MAX3420EETG+ suits environments where commercial-grade parts would drift or fail — factory-floor automation, outdoor telecom cabinets, and unventilated enclosures. The 24-TQFN (4x4 mm) package is a small footprint but requires a clean reflow profile and X-ray inspection for hidden solder joints under the exposed pad. The exposed pad also provides a thermal path; a via array under the pad to a ground plane keeps the junction temperature in check.","metaTitle":"MAX3420EETG+ USB Peripheral Controller, SPI Interface","metaDescription":"MAX3420EETG+ USB 2.0 peripheral controller with SPI interface. 3V-3.6V supply, 15mA, -40°C to 85°C, 24-TQFN.
