ST16C1550CJ28-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1550CJ28-F is a single-channel UART interface IC manufactured by MaxLinear, Inc. (formerly Exar). It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 1.5 Mbit/s. The device features 16-byte transmit and receive FIFOs to enhance throughput efficiency. It is housed in a 28-pin PLCC package with surface mount installation. The component supports RS232, RS422, and RS485 communication protocols and functions within an operating temperature range of 0°C to +70°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 16-byte transmit and receive FIFO buffers for improved data handling
• Supports multiple serial communication standards including RS232, RS422, and RS485
• Operates on a wide supply voltage range from 2.97V to 5.5V

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring reliable serial communication
• Embedded devices utilizing RS485 or RS422 bus networks
• Microcontroller-based systems needing UART expansion

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as MaxLinear, Inc., noting the historical association with Exar. Confirm the specific suffix CJ28-F corresponds to the 28-pin PLCC package variant. Ensure compliance with RoHS directives if required by the target application, as original Exar listings may indicate non-compliance depending on production date. Cross-reference the part number with official MaxLinear documentation to confirm current availability status.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate speed up to 1.5 Mbit/s is sufficient. The 16-byte FIFO size is suitable for burst data transmission but may require careful buffer management compared to higher-capacity models. Verify that the 28-pin PLCC footprint matches the PCB layout constraints. Consider thermal performance within the 0°C to +70°C commercial grade range for the intended environment.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x family of UART controllers. It serves as a bridge between parallel microprocessor buses and serial asynchronous data streams. The CJ28 suffix denotes the plastic leaded chip carrier package type. MaxLinear acquired the Exar product line, making this part part of their broader connectivity portfolio.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-compatible replacements within the ST16C155x series. Verify if newer revisions have updated packaging or compliance certifications. Ensure any substitute maintains the same 16-byte FIFO depth and 1.5 Mbit/s maximum data rate specification.
