MAX3421EEHJ+ Description

Short technical summary and product information.

The MAX3421EEHJ+ is a versatile USB Peripheral/Host Controller designed by Maxim Integrated. It integrates the necessary digital logic and analog circuitry to implement a full-speed USB peripheral or a full-/low-speed host, compliant with USB specification revision 2.0. The device features a built-in transceiver with ±15kV ESD protection and programmable USB connect/disconnect functionality.

 

Communication with the host system is handled via a SPI interface, operating up to 26MHz. This allows microprocessors, ASICs, or DSPs to add USB functionality using a simple 3- or 4-wire SPI connection. Internal level translators enable the SPI interface to operate at system voltages between 1.4V and 3.6V. The MAX3421EEHJ+ operates over an extended temperature range of -40°C to +85°C and is available in a 32-pin TQFP package.

 

This controller is suitable for applications requiring microprocessor-independent USB solutions. Its intelligent USB Serial Interface Engine (SIE) handles low-level USB protocol details, including error checking and bus retries, simplifying firmware development. The device also includes eight general-purpose inputs and eight general-purpose outputs for added flexibility.
