ST16C454CJ68TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C454CJ68TR-F is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 1.5 Mb/s. The device features a single-byte transmit and receive buffer for each channel, housed in a 68-pin PLCC package with a tape-and-reel configuration.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels for serial communication
• Supports standard RS-232 signaling levels
• Compatible with Intel and Motorola bus architectures

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring multiple serial ports
• Embedded computer interface modules
• Telecommunications equipment serial links

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR-F' indicates the tape-and-reel packaging variant distinct from tray options. Confirm the manufacturer designation remains MaxLinear despite historical branding transitions. Ensure the component matches the 68-PLCC physical footprint requirements for the target PCB design before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four separate serial interfaces are required within a single package constraint. The 1.5 Mb/s speed and single-byte buffering suit moderate throughput applications. Consider the PLCC-68 form factor for legacy socket compatibility or specific board layout constraints compared to surface-mount alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C554D/ST16C454D series of VLIO UARTs. It shares architectural similarities with the ST16C554DCJ68 variants but differs in FIFO depth, offering one byte per channel instead of sixteen. This distinction impacts buffer management strategies for high-throughput data transmission scenarios.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C454CJ68-F serves as the tray-packaged equivalent of this reel-part. For functional substitution, the ST16C554DCJ68-F provides identical pinout and logic but includes larger 16-byte FIFOs per channel.
