SC16IS752IBS,128

Controllers Overview

The SC16IS752IBS,128 is a dual-channel UART bridge IC manufactured by NXP Semiconductors. It converts I2C-bus or SPI signals to two independent full-duplex UART channels. The device features 64-byte transmit and receive FIFOs per channel and supports data rates up to 5 Mbit/s in 16x clock mode. It operates on 2.5 V or 3.3 V power supplies within an industrial temperature range of -40 °C to +95 °C. The component includes built-in IrDA SIR support up to 115.2 kbit/s, auto hardware flow control (RTS/CTS), and eight programmable I/O pins. It is housed in a 32-terminal HVQFN package.

Controllers Feature Summary

• Dual full-duplex UART channels with 64-byte FIFOs for reduced host software overhead
• Selectable I2C-bus or SPI interface with backward compatibility to the 16C450 register set
• Integrated automatic RS-485 driver direction control via RTS signal inversion
• Supports both hardware flow control (Auto-RTS/Auto-CTS) and programmable software flow control (Xon/Xoff)

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices requiring low power consumption
• Cellular data devices and IoT gateways

Controllers Selection Notes

Select the SC16IS752IBS,128 when a compact surface-mount solution is required for space-constrained designs. The HVQFN32 package offers thermal enhancement via an exposed center pad that must be soldered to the PCB ground plane for proper operation. Ensure the host controller supports either I2C Fast mode (400 kbit/s) or SPI Mode 0 (up to 4 Mbit/s) as dictated by system bandwidth requirements.

Controllers Part Context

This component belongs to the SC16IS7xx series of UART bridge controllers from NXP Semiconductors. It shares functional and electrical characteristics with the SC16IS762, though the latter supports higher SPI speeds (15 Mbit/s) and faster IrDA rates. The IB variant specifically denotes the HVQFN32 plastic thermal enhanced very thin quad flat package without leads.

Controllers Replacement Considerations

SC16IS762IBS,128: Functionally identical but supports SPI clock speeds up to 15 Mbit/s and IrDA SIR up to 1.152 Mbit/s.
