MAX3420EECJ+ by Analog Devices

USB Peripheral Controller with SPI Interface


The MAX3420E contains the digital logic and analog circuitry necessary to implement a full-speed USB peripheral compliant to USB specification rev 2.0. A built-in full-speed 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. The MAX3420E 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 functionality using the simple 3- or 4-wire SPI interface. Internal level translators allow the SPI interface to run at a system voltage between 1.71V and 3.6V. USB timed operations are done inside the MAX3420E with interrupts provided at completion so an SPI master does not need timers to meet USB timing requirements. The MAX3420E includes four general-purpose inputs and outputs so any microprocessor that uses I/O pins to implement the SPI interface can reclaim the I/O pins and gain additional ones. The MAX3420E operates over the extended -40°C to +85°C temperature range and is available in a 32-pin LQFP package (7mm x 7mm) and a space-saving 24-pin TQFN package (4mm x 4mm). FAQs: MAX3420E
