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 ±15kV ESD protection and

programmable USB connect and disconnect. An inter-

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

protocol details such as error checking 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, DSP, etc.) can add

USB peripheral or host functionality using the simple 3-

or 4-wire SPI interface.

The MAX3421E makes the vast collection of USB

peripherals available to any microprocessor, ASIC, or

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

solutions, for example, a USB keyboard 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.

Internal level translators allow the SPI interface to run at

a system voltage between 1.4V and 3.6V. 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.

The MAX3421E operates over the extended -40°C to

+85°C temperature range and is available in a 32-pin

TQFP package (5mm x 5mm) and a 32-pin TQFN pack-

age (5mm x 5mm).
