XR16C854DIV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854DIV-F is a quad enhanced Universal Asynchronous Receiver and Transmitter (UART) manufactured by MaxLinear. It features four independent channels, each equipped with 128-byte transmit and receive FIFOs to support high-speed data throughput up to 2 Mb/s. The device operates within a supply voltage range of 2.97 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. It is housed in a 64-pin LQFP surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 128-byte TX and RX FIFOs per channel
• Dual bus compatibility supporting Intel and Motorola interface protocols
• Integrated IrDA encoder/decoder and automatic flow control capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multi-port serial connectivity

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'DIV' against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Check for any Product Change Notifications (PCN) regarding package updates or material changes. Confirm availability status as distribution listings may indicate limited stock or long lead times.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple UART ports are required in a single footprint. Ensure the system power supply remains stable between 2.97 V and 5.5 V. Verify that the host microcontroller supports either Intel or Motorola bus modes. Consider thermal dissipation in the LQFP-64 package if operating at maximum data rates in enclosed environments.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854D series of enhanced UARTs. It shares functional similarities with other members like the XR16C854DCV-F but differs in packaging and temperature rating. The DIV suffix specifically denotes the LQFP-64 package variant suitable for surface mount assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DCV-F is a related variant within the same series, offering similar functionality but potentially differing in temperature range or package type. Cross-reference the exact suffix specifications before substitution.
