CP2102-GMR

CP2102-GMR is the tape-and-reel QFN-28 ordering code for the Silicon Labs CP2102 single-chip USB-to-UART bridge, listed word-for-word in the affected ordering part numbers appendix of the maker’s own product change notice on silabs.com (PCN #1005191A), with the maker’s product documentation fixing the package as QFN-28, 5 × 5 mm, with no GPIO pins. It is a USB 2.0 full-speed bridge with 1024 bytes of EEPROM for vendor and product strings, baud rates from 300 bps to 1 Mbps - the maker’s per-model figure for the CP2102 itself, not the 2 Mbps headline that belongs to other members of the bridge family - and an industrial operating range of -40 °C to +85 °C. Silicon Labs renders no per-code lifecycle word for this code in the captured material; the code stands in the maker’s current Classic USB Bridges line with a buying path and no discontinuation notice, and the status is stated in neutral terms pending confirmation at review. The selection point is the legacy CP2102 socket: designs qualified on this bridge keep their driver, EEPROM configuration flow and footprint instead of re-qualifying on the newer CP2102N generation. Selection advice: the GMR code is the reel form of this exact package - confirm the full code, and treat migration to the CP2102N generation as a porting exercise rather than a drop-in: the maker’s AN976 guide maps this bridge to the CP2102N QFN28 subject to VBUS sensing-divider and software differences, so the legacy footprint stays unless the design has been through that port. Parameters verified against the Silicon Labs CP2102 datasheet (baud-rate figures), the maker’s USB bridge documentation and PCN #1005191A, appendix A.
