USB97C202-MN-02

Controllers Overview

The SMSC USB97C202-MN-02 is a USB 2.0 Flash Media Controller designed to interface CompactFlash (CF) and SmartMedia (SM) devices with the USB 2.0 bus. It operates on a 3.3V supply and features an integrated 8051 microprocessor running at up to 30MHz. The device includes 12KB of internal SRAM for scratchpad use and supports firmware upgrades via the USB bus. It provides 16 general-purpose I/O pins for system control functions such as LED indicators and power management. The controller is housed in a 128-pin VTQFP package measuring 14x14mm with a 1mm height, supporting data transfer rates up to 1.875 MBps for device communication.

Controllers Feature Summary

• Integrates a high-speed USB 2.0 transceiver compliant with USB specifications.
• Supports direct interfacing with CompactFlash and SmartMedia storage devices.
• Includes an embedded 8051 microcontroller for flexible firmware execution.
• Provides multiple GPIO pins for peripheral control and status indication.

Controllers Applications

• Portable digital cameras requiring CF or SM card connectivity
• MP3 players and audio recorders using flash media
• Industrial data loggers with removable storage interfaces
• Consumer electronics with USB mass storage capabilities

Controllers Procurement Notes

Verify the specific suffix -MN-02 against manufacturer documentation to confirm pinout compatibility and voltage levels. Ensure the 3.3V supply requirement is met by the target system design. Confirm that the 128-pin VTQFP package dimensions align with the PCB footprint constraints. Check for lead-free compliance if required by regional regulations, noting the component may be leaded.

Controllers Selection Notes

Select this component when a dedicated solution for connecting legacy flash media formats like CompactFlash or SmartMedia to a USB host is required. It is suitable for applications needing a self-contained controller with built-in processing power rather than a passive bridge. Consider the 128-pin package size and thermal requirements during layout planning.

Controllers Part Context

This part belongs to the SMSC USB97 series of USB flash media controllers. These devices were developed to provide a complete system solution for integrating various flash memory types into USB-enabled products. The series typically includes variants supporting different media types and package options, positioning the USB97C202 as a specialized controller for CF and SM interfaces within the broader connectivity portfolio.

Controllers Replacement Considerations

Check for updated revisions from Microchip Technology, which acquired SMSC's connectivity assets. Verify functional equivalence regarding the 8051 core and USB 2.0 PHY before substitution. Ensure any replacement maintains the same 128-pin VTQFP form factor and electrical characteristics.
