Maxim Integrated (MAX3420EETG+) USB Interface, USB Peripheral Controller

Product OverviewThe MAX3420EETG+ is an USB peripheral controller with SPI interface in 24 pinTQFN package. It contains digital logic and analogue circuitry necessary toimplement a full speed USB peripheral compliant to USB specification rev 2.0. Abuilt-in full speed transceiver has ±15KV ESD protection and programmable USBconnect and disconnect. An internal serial interface engine (SIE) handles lowlevel USB protocol details such as error checking and bus retries. The MAX3420Eoperates using a register set accessed by an SPI interface that operates up to26MHz. Any SPI master (microprocessor, ASIC and DSP) can add USB functionalityusing simple 3 or 4-wire SPI interface. Internal level translators allow SPIinterface to run at a system voltage between 1.71V and 3.6V. USB timedoperations are done inside MAX3420E with interrupts provided at completion so anSPI master does not need timers to meet USB timing requirements.Supply voltage range from 3V to 3.6V, VCC supply current of 15mA and VL supplycurrent of 6mAOperating temperature range from -40°C to 85°CSimplifies adding USB to any system and microprocessor independent USB solutionPeripheral speed of 12MbpsFirmware/hardware control of an internal D + pull-up resistorAutomatically handles USB flow control and double bufferingHandles low level USB signalling detailsIncludes timers for USB time sensitive operations SPI master does not need totime eventsFour general purpose inputs and four general purpose outputsInterrupt output pin (level or programmable edge) allows polled or interruptdriven SPI interfaceApplicationsConsumer Electronics, Portable Devices, Sensing & InstrumentationProduct InformationUSB IC Type: USB Peripheral ControllerUSB Standard: USB 2.0Supply Voltage Min: 3VSupply Voltage Max: 3.6VInterface Case Style: TQFNNo. of Pins: 24PinsData Rate: 12MbpsNo. of Ports: 2 PortOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -MSL: MSL 1 - Unlimited
