USB Peripheral/Host Controller

with SPI Interface

General Description

Features

♦ Microprocessor-Independent USB Solution

The MAX3421E USB peripheral/host controller contains

the digital logic and analog circuitry necessary to

implement a full-speed USB peripheral or a full-/low-

speed host compliant to USB specification rev 2.0. A

built-in transceiver features 1ꢀ5k ESꢁ protection and

programmable USB connect and disconnect. An inter-

nal serial interface engine (SIE) handles low-level USB

protocol details such as error chec5ing and bus retries.

The MAX3421E operates using a register set accessed

by an SPI™ interface that operates up to 26MHz. Any

SPI master (microprocessor, ASIC, ꢁSP, etc.) can add

USB peripheral or host functionality using the simple 3-

or 4-wire SPI interface.

♦ Software Compatible with the MAX3420E USB

Peripheral Controller with SPI Interface

♦ Complies with USB Specification Revision 2.0

(Full-Speed 12Mbps Peripheral, Full-/Low-Speed

12Mbps/1.5Mbps Host)

♦ Integrated USB Transceiver

♦ Firmware/Hardware Control of an Internal D+

Pullup Resistor (Peripheral Mode) and D+/D-

Pulldown Resistors (Host Mode)

♦ Programmable 3- or 4-Wire, 26MHz SPI Interface

♦ Level Translators and V Input Allow Independent

The MAX3421E ma5es the vast collection of USB

peripherals available to any microprocessor, ASIC, or

ꢁSP when it operates as a USB host. For point-to-point

solutions, for example, a USB 5eyboard or mouse inter-

faced to an embedded system, the firmware that oper-

ates the MAX3421E can be simple since only a

targeted device is supported.

System Interface Voltage

♦ Internal Comparator Detects V

for Self-

BUS

Powered Peripheral Applications

♦ ESD Protection on D+, D-, and VBCOMP

♦ Interrupt Output Pin (Level- or Programmable-

Edge) Allows Polled or Interrupt-Driven SPI

Interface

Internal level translators allow the SPI interface to run at

a system voltage between 1.4k and 3.6k. USB-timed

operations are done inside the MAX3421E with inter-

rupts provided at completion so an SPI master does not

need timers to meet USB timing requirements. The

MAX3421E includes eight 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.

♦ Eight General-Purpose Inputs and Eight General-

Purpose Outputs

♦ Interrupt Signal for General-Purpose Input Pins,

Programmable Edge Polarity

♦ Intelligent USB SIE

♦ Automatically Handles USB Flow Control and

Double Buffering

The MAX3421E operates over the extended -40°C to

+8ꢀ°C temperature range and is available in a 32-pin

TQFP pac5age (ꢀmm x ꢀmm) and a 32-pin TQFN pac5-

age (ꢀmm x ꢀmm).

♦ Handles Low-Level USB Signaling Details

♦ Contains Timers for USB Time-Sensitive

Operations so SPI Master Does Not Need to Time
