MAX3420EETG+T Datasheet
Product Details
General Description
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 internal serial-interface engine (SIE) handles low-level USB
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.
Features
♦ 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 VL Input Allow Independent System Interface
Voltage
♦ Internal Comparator Detects VBUS for Self-Powered Applications
♦ ESD Protection on D+, D-, and VBCOMP
♦ 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
Handles Low-Level USB Signaling Details
Contains Timers for USB Time-Sensitive Operations So SPI Master
Does Not Need to Time Events
♦ Built-In Endpoint FIFOs
EP0: CONTROL (64 Bytes)
EP1: OUT, Bulk or Interrupt, 2 x 64 Bytes (Double-Buffered)
EP2: IN, Bulk or Interrupt, 2 x 64 Bytes (Double-Buffered)
EP3: IN, Bulk or Interrupt (64 Bytes)
♦ Double-Buffered Data Endpoints Increase
Throughput by Allowing the SPI Master to Transfer Data Concurrently
with USB Transfers Over the Same Endpoint
♦ SETUP Data Has Its Own 8-Byte FIFO, Simplifying Firmware
♦ Four General-Purpose Inputs and Four GeneralPurpose Outputs
♦ Space-Saving LQFP and TQFN Packages
