It offers exceptional read (-24 dBm) and write (-22 dBm) sensitivity, enabling long read ranges and fast inventory of dense tag populations. Innovative features include Self-Adjust for automatic sensitivity tuning, Dynamic Backscatter for regulatory compliance, Memory Safeguard (ECC and parity check), and compatibility with single-slit antennas. Delivered on 12-inch wafers with large, rotation-tolerant Au pads, the chip supports 96-bit pre-serialized EPC, 100k write-cycle endurance, and a wide -40°C to +85°C operating range, making it ideal for global RFID deployments in retail, e-commerce, and supply-chain environments.","enriched":true,"url_status":"ok","link_status":"valid","last_checked":"2026-11-01T03:31:28.371+00:00","last_status_code":200,"last_content_type":"application/pdf","created_at":"2026-06-14T16:30:56.111445+00:00","manufacturer_id":"6daaf1cc-d0e6-40c7-aba0-a08b4c3493fe","chip_type":"tag_ic","dual_interface":false,"is_family_hub":false,"meta_description":"NXP UCODE 9 (SL3S1206) EPC Gen2v2.1 UHF RFID tag IC with -24 dBm read sensitivity, 96-bit EPC, and Self-Adjust for fast retail inventory.","faq":[{"a":"The UCODE 9 offers -24 dBm read sensitivity and -22 dBm write sensitivity, enabling long read ranges and reliable performance in dense tag environments.","q":"What is the read sensitivity of the UCODE 9 chip?"},{"a":"The UCODE 9 operates in the UHF frequency range of 840–960 MHz, making it suitable for global RFID deployments across different regulatory regions.","q":"What frequency range does the NXP UCODE 9 operate on?"},{"a":"The UCODE 9 provides 96 bits of EPC memory, 96-bit TID including a 48-bit unique serial number, and a 32-bit kill password for access control.","q":"How much memory does the UCODE 9 have for EPC storage?"},{"a":"Self-Adjust is an innovative feature that automatically tunes the chip's sensitivity to optimize performance across varying read conditions and tag populations.","q":"What is Self-Adjust on the UCODE 9?"},{"a":"The UCODE 9 operates across a wide temperature range of -40°C to +85°C, suitable for challenging retail, logistics, and industrial environments.","q":"What temperature range can the UCODE 9 operate in?"},{"a":"The UCODE 9 supports 100,000 write-cycle endurance with Memory Safeguard protection including ECC and parity checks for data integrity.","q":"How many write cycles does the UCODE 9 support?"}],"standards":["iso-18000-63-epc-gen2"],"alternatives":["8de5da07-a0fe-45c9-8a9e-45c34369be6e","b5848562-36ca-45fa-846a-e17981fc0f4f","22a4ab88-4087-4a87-a31a-066d187b5641","56ed1649-180b-46f9-958a-937c67a14dd0"],"no_direct_competitor":false,"long_form_html":null,"og_image_url":null,"canonical_url":"https://rfid-datasheet.com/chip/ucode-9"}}
