ST16C552ACJ68TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C552ACJ68TR-F is a dual Universal Asynchronous Receiver/Transmitter (UART) from the ST68C552 series, manufactured by MaxLinear. It operates on a single 5V supply and supports data rates up to 1.5 Mbps. The device integrates 16-byte transmit and receive FIFOs for each channel to enhance throughput. It features full modem control handshaking signals and is housed in a 68-pin PLCC package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels with integrated 16-byte FIFOs
• Full hardware modem control interface support
• Compatible with standard Intel and Motorola bus protocols

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial serial communication gateways
• Multi-port I/O expansion modules
• Embedded system serial interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration against the manufacturer's official documentation. Confirm RoHS compliance status and lead times directly with authorized distributors or MaxLinear sales representatives prior to ordering.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual asynchronous serial ports are required within a single IC footprint. Ensure the design accommodates the 68-pin PLCC package dimensions and thermal requirements. Verify that the 5V logic levels match the target system voltage domain.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST68C55x family of high-performance UARTs. It serves as a functional equivalent to legacy MC68681 controllers but offers improved FIFO performance. The AC grade specifies the operational temperature range suitable for commercial applications.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Cross-reference with ST16C554 variants for quad-channel requirements. Check ST16C654 models for increased 64-byte FIFO capacity. Verify pin compatibility with existing PCB layouts before substituting.
