Part Details:

19-3781; Rev 2; 6/07 EVALUATION KIT AVAILABLE USB Peripheral Controller with SPI Interface MAX3420E General Description Features The MAX3420E contains the digital logic and analog Microprocessor-Independent USB Solution circuitry necessary to implement a full-speed USBperipheral compliant to USB specification rev 2.0. A Complies with USB Specification Revision 2.0 built-in full-speed transceiver features ±15kV ESD pro- (Full-Speed Operation) tection and programmable USB connect and discon- Integrated Full-Speed USB Transceiver nect. An internal serial-interface engine (SIE) handleslow-level USB protocol details such as error checking Firmware/Hardware Control of an Internal D+ and bus retries. The MAX3420E operates using a regis- Pullup Resistor ter set accessed by an SPITM interface that operates up Programmable 3- or 4-Wire 26MHz SPI Interface to 26MHz. Any SPI master (microprocessor, ASIC, DSP,etc.) can add USB functionality using the simple 3- or Level Translators and VL Input Allow Independent 4-wire SPI interface. System Interface Voltage Internal level translators allow the SPI interface to run at Internal Comparator Detects VBUS for a system voltage between 1.71V and 3.6V. USB timed Self-Powered Applications operations are done inside the MAX3420E with inter- ESD Protection on D+, D-, and VBCOMP rupts provided at completion so an SPI master does notneed timers to meet USB timing requirements. The Interrupt Output Pin (Level or Programmable MAX3420E includes four general-purpose inputs and Edge) Allows Polled or Interrupt-Driven SPI outputs so any microprocessor that uses I/O pins to Interface implement the SPI interface can reclaim the I/O pins Intelligent USB Serial-Interface Engine (SIE) and gain additional ones. Automatically Handles USB Flow Control and The MAX3420E operates over the extended -40°C to Double Buffering +85°C temperature range and is available in a 32-pinLQFP package (7mm x 7mm) and a space-saving 24- Handles Low-Level USB Signaling Details pin TQFN package (4mm x 4mm). Contains Timers for USB Time-Sensitive Applications Operations So SPI Master Does Not Need toTime Events Cell Phones PLCs Built-In Endpoint FIFOs PC Peripherals Set-Top Boxes
