USB2241I-AEZG-06

Specialized Overview

The USB2241I-AEZG-06 is a USB 2.0 compliant, Hi-Speed bulk-only mass storage class peripheral controller designed for reading and writing to flash media from the Memory Stick (MS) and Secure Digital (SD) families. It features a fully integrated single-chip solution with an 8051 8-bit microprocessor operating at 60 MHz, providing 64 KB ROM and 14 KB RAM. The device supports a single external 3.3 V supply source, utilizing internal regulators to provide 1.8 V internal core voltage. It operates within an industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Hardware-controlled data flow architecture for self-mapped media and pipelined hardware support for non-self-mapped media access.
• Integrated on-board 24 MHz crystal driver circuit with optional external clock input capability.
• Built-in internal card power FET featuring 200 mA drive capability and fold-back short circuit protection.
• Extended configuration options accessible via external serial EEPROM or SMBus slave port.

Specialized Applications

• Flash media card readers and writers
• Desktop and mobile PCs
• Printers
• Consumer A/V and media players/viewers

Specialized Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature grade, and any proprietary firmware configurations. Ensure compatibility with the target system's power requirements and interface protocols before procurement.

Specialized Selection Notes

Select this component for designs requiring dedicated SD and Memory Stick support without xD-Picture Card functionality. Consider the industrial temperature rating (-40°C to +85°C) for robust environmental operation. Verify that the 36-pin QFN package fits the available PCB real estate constraints.

Specialized Part Context

This part belongs to the USB224x family of ultra-fast USB 2.0 multi-format flash media controllers. It shares the same low pin count 36-pin QFN package as other variants in the series but is specifically configured for SD and MS media formats.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip Technology directly for current replacement recommendations or updated product line information.
