The pad is electrically connected to GND. The Tape & Reel and Cut Tape options mean the part is available in production-friendly reel quantities for pick-and-place, or in smaller cut-tape lengths for prototyping and low-volume builds. ## Lifecycle and compliance The SC16IS752IBS,128 is listed as Active and ROHS3 compliant. The ROHS3 status means it meets the latest EU restriction levels, including exemptions for lead in solder joints — no special handling or exemption expiry tracking needed.","metaTitle":"SC16IS752IBS,128 Dual UART Controller, I2C/SPI, 32-HVQFN","metaDescription":"NXP SC16IS752IBS,128 dual UART bridge controller with I2C/SPI interface.

The dual UART channels can be configured independently for either protocol, so one channel could drive an RS232 debug console while the other handles an RS485 sensor bus."},{"question":"SC16IS752IBS vs SC16IS752: what is the difference?","answer":"The SC16IS752IBS,128 is the lead-free, ROHS3-compliant variant in the 32-HVQFN package. The base SC16IS752 part number typically refers to the same die in a different package option (often a TSSOP or QFN without the 'IBS' suffix). The functional behavior and register map are identical — the difference is the package and environmental compliance level. For a pin-compatible alternative, check the SC16IS752IPW (TSSOP) if the HVQFN footprint does not suit the PCB layout."},{"question":"What is the SC16IS752IBS?","answer":"The SC16IS752IBS is a dual UART controller from NXP that adds two hardware serial ports to a system via an I2C or SPI host interface. It handles RS232 and RS485 protocol framing, freeing the host MCU from bit-banging or dedicated UART peripheral requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/SC16IS752IBS128","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/SC16IS752IBS128 when reusing this data.
