MAXIM INTEGRATED / ANALOG DEVICES MAX3420EETG USB Controller

The MAX3420EETG+ is a USB peripheral controller with an SPI interface, available in a 24-pin TQFN package. It integrates digital and analog circuitry necessary to implement a full-speed USB peripheral compliant with USB 2.0 specifications. The device features a built-in full-speed transceiver with ±15kV ESD protection and programmable USB connect/disconnect. An internal Serial Interface Engine (SIE) manages low-level USB protocol tasks, such as error checking and bus retries. The controller uses a register set accessible via an SPI interface operating up to 26MHz, making it suitable for any SPI master, including microprocessors, ASICs, and DSPs, to easily add USB functionality. Internal level translators enable operation at system voltages between 1.71V and 3.6V. The device handles USB timing operations internally and provides interrupt signals upon completion, eliminating the need for external timers. Power supply requirements include 3V to 3.6V with a VCC supply current of 15mA and VL current of 6mA. It supports an operating temperature range from -40°C to 85°C and offers a USB data transfer rate of 12 Mbps. The controller simplifies integrating USB into any system, being microprocessor-independent, and includes firmware/hardware control of an internal D+ pull-up resistor. It automatically manages USB flow control, double buffering, low-level signaling, and includes timers for time-sensitive operations. Additional features include four general-purpose inputs and outputs, and an interrupt output pin with programmable edge or level triggering for polled or interrupt-driven SPI communication.
