USB97C201-MN

Controllers Overview

The USB97C201-MN is a USB 2.0 Flash Media Controller manufactured by SMSC, designed to interface CompactFlash (CF) and SmartMedia (SM) devices with the USB 2.0 bus. It supports data transfer rates up to 15 Mbps for host interfaces and 1.875 MBps for device connections. The component operates on a 3.3V supply voltage and features a 128-pin VTQFP package measuring 14 x 14 mm with a height of 1 mm. It includes an embedded 8-bit microprocessor running at 30 MHz, 12 KB of internal SRAM, and 768 bytes of additional SRAM. The controller provides 16 GPIO pins and supports firmware upgrades via the USB bus.

Controllers Procurement Notes

Verify the specific suffix 'MN' against official SMSC documentation to confirm pinout and electrical characteristics. Ensure compatibility with 3.3V logic levels and check for leaded content requirements as indicated in related datasheets. Confirm package dimensions match the 14x14mm VTQFP-128 specification before integration into PCB designs.

Controllers Selection Notes

Select this controller when interfacing CF or SM media with USB 2.0 hosts is required. Consider the 30 MHz processor speed and 12 KB SRAM for firmware complexity. Verify that the 16 GPIO pins meet system control needs. Ensure the design accommodates the 128-pin VTQFP package constraints and thermal requirements for continuous operation.

Controllers Part Context

The USB97C201 belongs to the SMSC USB97 series of USB 2.0 flash media controllers. This family addresses the need for direct connection between legacy flash formats and modern USB interfaces. The USB97C201 specifically targets applications requiring robust support for both CompactFlash and SmartMedia standards within a single integrated solution.

Controllers Replacement Considerations

Check for USB97C211 or USB97C223 as potential functional equivalents within the same product line. Verify pin compatibility and firmware requirements before substitution. Ensure the replacement part supports the same flash media types and USB 2.0 speeds.
