SC16IS752IPW-S

Controllers Overview

The SC16IS752IPW-S is a dual-channel UART bridge IC manufactured by NXP Semiconductors, housed in a TSSOP28 package. It provides an interface between I2C-bus/SPI and two independent full-duplex UART channels. The device supports data rates up to 5 Mbit/s and includes 64 bytes of transmit and receive FIFOs per channel. Operating voltages are 2.5 V or 3.3 V, with an industrial temperature range from -40 °C to +95 °C. It features built-in IrDA SIR support up to 115.2 kbit/s, auto hardware flow control, and eight programmable I/O pins.

Controllers Feature Summary

• Dual full-duplex UART channels with 64-byte FIFOs for reduced host software overhead
• Selectable I2C-bus (Fast mode) or SPI (Mode 0) interface for system integration
• Backward compatible register set with the industry-standard 16C450 UART
• Integrated automatic RS-485 driver direction control via RTS signal

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix 'S' against official NXP documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status distinct from standard listings. Confirm RoHS and halogen-free status via the manufacturer's Certificate of Analysis. Ensure the ordering part number matches the exact package type and speed grade required for the design.

Controllers Selection Notes

Select this component when expanding serial communication capabilities on microcontrollers with limited native UART resources. The SC16IS752 is suitable for designs requiring protocol conversion between I2C/SPI and RS-232/RS-485. Consider the SC16IS762 if SPI clock speeds exceeding 4 Mbit/s or higher IrDA baud rates are necessary, as it shares identical functionality otherwise.

Controllers Part Context

The SC16IS752 belongs to the SC16IS7xx series of I2C/SPI to UART bridge controllers. It is functionally paired with the single-channel SC16IS750 and the high-speed SC16IS762. The IPW suffix indicates the TSSOP28 plastic thin shrink small outline package. This family is designed to replace legacy parallel UARTs in modern embedded systems.

Controllers Replacement Considerations

SC16IS750: Single channel equivalent. SC16IS762: Higher speed SPI/IrDA variant. SC16C550B: Legacy parallel UART alternative.
