ST16C1550CJ28TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1550CJ28TR-F is a single-channel serial I/O controller manufactured by MaxLinear, Inc., housed in a 28-pin plastic quad flat pack (PQCC28) package. It supports asynchronous and bit-oriented communication protocols with a maximum data transmission rate of 0.1875 MBps. The device operates on an 8-bit external data bus and utilizes a 3-bit address bus for register selection. It features CMOS technology and includes one DMA channel. The component is designed to operate within a temperature range of -40 °C to 70 °C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Single-channel serial interface capability supporting RS-232 and RS-485 standards
• Integrated FIFO buffer for efficient data handling
• Low power operation mode for energy conservation
• Compatibility with standard microprocessor systems via parallel interface

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring reliable serial communication
• Embedded devices needing UART expansion
• Data acquisition systems with multiple serial ports

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as MaxLinear or Exar, as both entities have produced this part number. Confirm the package type is PQCC28 and check for lead-free compliance status, as older versions may not be RoHS compliant. Ensure the operating temperature range matches the specific application requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with FIFO buffering is required in a compact 28-pin package. Compare against the ST16C1551 variant if dual channels are needed. Verify voltage supply compatibility, noting that some variants support minimum supply voltages down to 2.97V. Check pinout compatibility with existing PCB layouts.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x family of serial I/O controllers, which are widely used in embedded systems. The CJ28 suffix indicates the 28-pin plastic quad flat pack package. The TR-F suffix typically denotes tape and reel packaging with lead-free composition. This family provides a drop-in replacement for legacy UART controllers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C1551CJ28 is a dual-channel alternative from the same family. For single-channel needs, verify pin compatibility. Other potential replacements include the XR16L872 series, though pinouts and features may differ.
