ST16C1551CJ28TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1551CJ28TR-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It features a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports data rates up to 1.5 Mbps and operates within a supply voltage range of 2.97 V to 5.5 V. It is housed in a 28-pin PLCC package and is designed for industrial temperature ranges, typically from -40°C to +85°C. The UART includes standard control signals such as RTS, CTS, DSR, DTR, RI, and DCD, compatible with RS-232, RS-422, and RS-485 standards.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR-F' indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as MaxLinear, Inc., noting that prior iterations may have been branded under Exar. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with substantial FIFO depth is required. It is suitable for applications where CPU intervention must be minimized during serial data transfers. Consider the 28-pin PLCC package constraints for PCB layout. Verify that the operating temperature range aligns with the environmental conditions of the target application.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x series of UART controllers. It is functionally similar to the ST16C1550 but offers enhanced FIFO capabilities. The series is widely used in legacy and modern embedded systems. MaxLinear acquired the UART product line from Exar, maintaining continuity in specifications and pinouts for design upgrades.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements include the ST16C1550CJ28-F. Verify pin-to-pin compatibility before substitution. Other variants in the ST16C155x family may offer different package options or temperature ranges. Always consult the latest datasheets to ensure functional equivalence.
