MAX3420E

USB Peripheral Controller with SPI Interface

General Description

Beneﬁts and Features

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

internalserial-interfaceengine(SIE)handleslow-levelUSB

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.

● Simplifies Adding USB to Any System

• Microprocessor-Independent USB Solution

• Complies with USB Speciﬁcation Revision 2.0

(Full-Speed Operation)

• Integrated Full-Speed USB Transceiver

• Firmware/Hardware Control of an Internal D+

Pullup Resistor

• Programmable 3 or 4-Wire 26MHz SPI Interface

• Intelligent USB Serial-Interface Engine (SIE)

• Automatically Handles USB Flow Control and

Double Buffering

• Handles Low-Level USB Signaling Details

• Includes Timers for USB Time-Sensitive Operations,

So SPI Master Does Not Need to Time Events

• Four General-Purpose Inputs and Four General-

Purpose Outputs

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.

● Internal Comparator Detects V

for Self-Powered

BUS

Applications

● Interrupt Output Pin (Level or Programmable Edge)

Allows Polled or Interrupt-Driven SPI Interface

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).

● Double-Buffered Data Endpoints Increase

Throughput by Allowing the SPI Master to Transfer

Data Concurrently with USB Transfers Over the

Same Endpoint

Applications

• Built-In Endpoint FIFOs

● Cell Phones

• EP0: CONTROL (64 Bytes)

● PC Peripherals

● Microprocessors and DSPs

● Custom USB Devices

● Cameras

• EP1: OUT, Bulk or Interrupt, 2 x 64 Bytes

(Double-Buffered)

• EP2: IN, Bulk or Interrupt, 2 x 64 Bytes

(Double-Buffered)

● Desktop Routers

● PLCs

● Set-Top Boxes

● PDAs

● MP3 Players

● Instrumentation

• EP3: IN, Bulk or Interrupt (64 Bytes)

● SETUP Data Has Its Own 8-Byte FIFO, Simplifying

Firmware

● ESD Protection on D+, D-, and VBCOMP Improves

System Reliability
