Product details

Package and layout — 32-HVQFN with exposed pad

The 32-HVQFN (5x5 mm) package with exposed pad requires a thermal via array under the pad for both heat dissipation and ground return. 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.

Frequently asked questions

Does SC16IS752IBS support RS485?

Yes, the SC16IS752IBS supports both RS232 and RS485 protocols. 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.

SC16IS752IBS vs SC16IS752: what is the difference?

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.

What is the SC16IS752IBS?

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.
