ST16C454CJ68-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C454CJ68-F is a quad universal asynchronous receiver/transmitter (UART) manufactured by MaxLinear, Inc. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 1.5 Mbps. The device features 16-byte transmit and receive FIFOs for each channel. It is housed in a PLCC-68 package and is rated for an operating temperature range of 0°C to +70°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad UART architecture with dedicated 16-byte FIFOs per channel
• Compatible with Intel and Motorola bus protocols
• Supports 3.3 V and 5 V logic levels

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multiple serial ports

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C). Confirm the PLCC-68 package availability through authorized distributors. Check for end-of-life notices or product change notifications from MaxLinear before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required with FIFO buffering. Ensure the application environment stays within the 0°C to +70°C commercial temperature limits. Verify that the system power supply falls within the 2.97 V to 5.5 V operational range.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C554/ST16C654 series family of quad UARTs. It shares functional similarities with other members like the ST16C554DIQ64-F but differs in package type and temperature rating. The 'C' suffix typically denotes commercial grade operation compared to industrial variants.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements include the ST16C554DCJ68-F, which offers identical functionality in the same PLCC-68 package but may have different temperature specifications. Verify pinout compatibility and FIFO sizes when substituting.
