USB97C210-NE

Controllers Overview

The USB97C210-NE is a USB 2.0 Flash Drive Controller manufactured by SMSC, designed to interface flash memory devices with the USB bus. It supports SmartMedia and NAND flash technologies with data transfer rates up to 15MB/sec. The device features an integrated 8-bit microprocessor executing at 30MHz, accompanied by 12KB of internal SRAM for scratchpad operations and 768 bytes for program execution or storage. It includes a built-in hardware 1-bit ECC engine and operates with a 2.5V core supply and 3.3V I/O tolerant to 5V inputs. The component is housed in a 128-pin VTQFP package measuring 14x14mm with a 1mm height.

Controllers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm voltage requirements and package variations. Ensure compatibility with existing firmware architectures when integrating the internal microprocessor. Confirm lead times and availability through authorized distributors as standard stock levels may vary. Validate that the selected variant meets the necessary regulatory compliance standards for the target market.

Controllers Selection Notes

Select this controller for applications requiring direct integration of SmartMedia or NAND flash without external protocol bridges. Consider the 30MHz processor speed and available SRAM for complex firmware logic. Verify power budget constraints, noting the 2.5V core and 3.3V I/O requirements. Ensure the design accommodates the 128-pin VTQFP footprint and thermal dissipation needs for continuous operation.

Controllers Part Context

The USB97C210-NE belongs to the SMSC USB97 series of USB 2.0 flash media controllers. This family provides integrated solutions for connecting various flash memory types to USB hosts. The component distinguishes itself by combining the USB transceiver, mass storage controller, and microprocessor in a single package, reducing bill-of-materials complexity for embedded storage designs.

Controllers Replacement Considerations

Direct substitutes within the same product line include the USB97C211 and USB97C242. Verify pinout compatibility and firmware binary compatibility before swapping. The USB97C211 offers similar functionality with potential minor electrical differences. Always validate electrical characteristics and software support with the manufacturer prior to implementation.
