SC16IS762IBS,157

Controllers Overview

The SC16IS762IBS,157 is a dual-channel UART with I2C-bus/SPI interface manufactured by NXP Semiconductors. It offers data rates up to 5 Mbit/s and supports SPI clock speeds up to 15 Mbit/s. The device includes 64-byte transmit and receive FIFOs, IrDA SIR support up to 1.152 Mbit/s, and eight programmable I/O pins. Operating voltages are 2.5 V or 3.3 V, with an industrial temperature range of -40 °C to +95 °C. It features hardware and software flow control, automatic RS-485 support, and sleep current less than 30 µA at 3.3 V.

Controllers Feature Summary

• Dual full-duplex UART channels with selectable I2C-bus or SPI interface
• Built-in IrDA encoder and decoder supporting high-speed SIR communication
• Advanced flow control including auto hardware RTS/CTS and programmable Xon/Xoff software flow control
• Backward compatible register set with the standard 16C450 UART

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices requiring low power consumption
• Cellular data devices and hand-held terminals

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental compliance status. Confirm that the component meets all required RoHS and REACH directives for your target market. Ensure the supply chain source provides valid traceability certificates for quality assurance purposes.

Controllers Selection Notes

Select this component when high-speed SPI interface performance up to 15 Mbit/s is required compared to the 4 Mbit/s limit of the SC16IS752 variant. Choose this part if IrDA SIR speeds exceeding 115.2 kbit/s are necessary for the application. Ensure the design accommodates the HVQFN32 package thermal requirements and utilizes the available GPIO pins effectively.

Controllers Part Context

This component belongs to the SC16IS752/SC16IS762 family of bridge IC solutions. It serves as a serial-to-I2C/SPI converter enabling seamless protocol conversion. The device is functionally identical to the SC16IS752 except for its enhanced SPI clock speed and higher IrDA SIR capability, making it suitable for demanding embedded serial communication tasks.

Controllers Replacement Considerations

The SC16IS752IBS is a functional substitute but operates with a lower maximum SPI clock speed of 4 Mbit/s and reduced IrDA SIR support. Verify that the system timing margins accommodate the slower interface speed before implementing this replacement in existing designs.
