USB Peripheral Controller

with SPI Interface

General Description

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 ±±15k ESꢀ pro-

tection and programmable USB connect and discon-

nect. An internal SIE (serial-interface engine) handles

low-level USB protocol details such as error chec5ing

and bus retries. The MAX3420E operates using a regis-

ter set accessed by an SPI interface that operates up to

26MHz. Any SPI master (microprocessor, ASIC, ꢀSP,

etc.) can add USB functionality using the simple 3- or

4-wire SPI interface.

♦ 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

♦ Level Translators and V Input Allow Independent

System Interface Voltage

Internal level translators allow the SPI interface to run at

a system voltage between ±.7±k and 3.6k. USB timed

operations are done inside the MAX3420E with inter-

rupts 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

Self-Powered Applications

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

for

BUS

♦ Interrupt Output Pin (Level or Programmable

Edge) Allows Polled or Interrupt-Driven SPI

Interface

♦ Intelligent USB Serial Interface Engine (SIE)

Automatically Handles USB Flow Control and

Double Buffering

The MAX3420E operates over the extended -40°C to

+81°C temperature range and is available in a 32-pin

TQFP pac5age (7mm x 7mm) and a space-saving 24-

pin TQFN pac5age (4mm x 4mm).
