USB2660I-JZX-03-TR

Specialized Overview

The USB2660I-JZX-03-TR is a Hi-Speed USB 2.0 hub and multi-format flash media controller combo solution in a 64-pin QFN package. It provides two exposed downstream USB ports for peripheral expansion and integrates a dedicated flash media reader attached to a third internal port as a USB Compound Device. The device supports SD, MMC, Memory Stick, and xD-Picture Card formats. It operates on a single 3.3 V supply with an internal 1.8 V regulator, features 9 KB RAM and 64 KB ROM, and supports the industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports Secure Digital, MultiMediaCard, Memory Stick, and xD-Picture Card specifications.
• Includes programmable PortMap, PortSwap, and PHYBoost features for flexible PCB design and signal integrity.
• Configurable via external I2C EEPROM or SPI Flash ROM.

Specialized Applications

• Desktop and mobile PCs
• Printers
• GPS navigation systems
• Consumer A/V devices

Specialized Procurement Notes

Verify the specific ordering suffix '-TR' indicates tape and reel packaging against the manufacturer's official documentation. Confirm that the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C) as specified in the datasheet. Ensure compatibility with required external configuration memory (I2C or SPI) for the intended application.

Specialized Selection Notes

Select this component when a combined USB hub and card reader solution is required for industrial environments. The USB2660i variant is necessary for temperatures below 0°C. Consider the integrated transaction translator for connecting Full-Speed and Low-Speed peripherals. Verify that the 64-pin QFN package fits the board layout constraints.

Specialized Part Context

This part belongs to the USB2660/USB2660i series from Microchip Technology (formerly SMSC). The 'i' suffix denotes the industrial temperature grade, while the base model supports commercial ranges. The series is designed as a cost-effective, energy-efficient combo solution for USB expansion and flash media integration.
