Controllers datasheet and documents for MAX3421EEHJ+T

MAX3421EEHJ+T

Controllers Overview

The MAX3421EEHJ+T is a USB peripheral/host controller compliant with USB specification revision 2.0, housed in a 32-pin TQFP package. It operates within a supply voltage range of 3V to 3.6V and supports data rates up to 12 Mb/s for full-speed peripherals or hosts. The device features an SPI interface capable of clocking up to 26MHz and includes an internal serial interface engine (SIE) for protocol handling. It provides ±15kV ESD protection on D+, D-, and VBCOMP pins. Operating temperatures range from -40°C to +85°C.

Controllers Feature Summary

Microprocessor-independent USB solution compatible with MAX3420E software
Integrated USB transceiver with programmable connect/disconnect capabilities
Intelligent SIE automatically handles flow control, double buffering, and low-level signaling
Internal level translators allow independent system interface voltage operation

Controllers Applications

Embedded systems
Medical devices

Controllers Procurement Notes

Verify the specific suffix EEHJ+T against official manufacturer documentation to confirm the 32-pin TQFP package configuration. Ensure that the ordering details match the lead-free/RoHS-compliant status indicated by the plus sign. Cross-reference the part number with authorized distributors to validate current availability and authenticity before procurement.

Controllers Selection Notes

Select this component when a microprocessor requires USB host or peripheral functionality via a simple SPI interface. It is suitable for applications needing to interface with various USB peripherals without dedicated USB controllers. Consider the 32-pin TQFP package constraints and the requirement for an external 12MHz crystal oscillator for proper clock generation.

Controllers Part Context

This component belongs to the MAX3421E series, which integrates digital logic and analog circuitry for USB implementation. It serves as a bridge between standard SPI masters and USB devices, simplifying firmware development by offloading timing-sensitive operations. The series supports both full-speed and low-speed modes depending on the operational configuration.
