USB2660-JZX

Specialized Overview

The Microchip Technology USB2660-JZX is a fully integrated single-chip solution combining a USB 2.0 compliant Hi-Speed hub, card reader, and protocol converter. It features two exposed downstream USB ports for peripheral expansion and an internally attached flash media reader on a third port as a USB Compound Device. The device supports Secure Digital (SD), MultiMediaCard (MMC), Memory Stick (MS), and xD-Picture Card formats. It operates with a single external 3.3 V supply source, utilizing internal regulators to provide a 1.8 V core voltage. The component is housed in a 64-pin QFN lead-free package.

Specialized Feature Summary

• Integrates a Hi-Speed USB 2.0 hub with two downstream ports and a dedicated multi-format flash media controller.
• Supports multiple flash media standards including SD, MMC, Memory Stick, and xD-Picture Card via multiplexed or dedicated interfaces.
• Includes programmable PortMap for flexible port mapping and PortSwap for simplified PCB trace alignment.
• Features PHYBoost technology to adjust transceiver drive strength and recover signal integrity.

Specialized Applications

• Desktop and mobile PCs
• Printers
• GPS navigation systems
• Media players and viewers
• Consumer A/V equipment

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Ensure that any required licenses for supported media formats, such as xD-Picture Card, are secured prior to implementation. Confirm that the selected variant matches the intended temperature range requirements for the target application environment.

Specialized Selection Notes

Select the USB2660-JZX variant based on the required operating temperature range, noting that the 'i' suffix typically denotes industrial specifications. Evaluate the need for external configuration memory, such as I2C EEPROM or SPI Flash, to customize vendor IDs and product strings. Consider the available GPIO count and power management options when designing the host interface circuitry.

Specialized Part Context

This component belongs to the USB2660/USB2660i series, which serves as a combo solution for USB expansion and flash media integration. Originally developed by SMSC, this product line is now part of Microchip Technology's portfolio. The series is designed to provide cost-effective and energy-efficient connectivity for mixed-speed USB environments.
