MAX3421EEHJ+T, USB интерфейс, USB Контроллер Host/Периферии с Защитой от ЭСР, USB 2.0, 3 В, 3.6 В, TQFP

The MAX3421EEHJ+T is a USB peripheral/host controller with SPI interface in 32 pin TQFP package. It contains digital logic and analogue circuitry necessary to implement a full speed USB peripheral or a full speed/low speed host compliant to USB specification rev 2.0. A built-in transceiver features ±15kV ESD protection and programmable USB connect and disconnect. An internal serial interface engine (SIE) handles low level USB protocol details such as error checking and bus retries. It operates using a register set accessed by an SPI interface that operates up to 26MHz. Any SPI master (microprocessor, ASIC, DSP etc.) can add USB peripheral or host functionality using the simple 3-wire or 4-wire SPI interface. It has a firmware/hardware control of an internal D+ pull-up resistor (peripheral mode) & D+/D- pull-down resistors (host mode). It is used in embedded systems, microprocessors and DSPs, custom USB devices, cameras, MP3 Players and instrumentation.
