ST16C1450CJ28-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1450CJ28-F is a universal asynchronous receiver and transmitter (UART) fabricated in an advanced CMOS process. It operates within a voltage range of 2.97V to 5.5V and supports data rates up to 1.5 Mbps with a 24 MHz clock input. The device features a single byte transmit holding register (THR) and a single byte receive holding register (RHR). It includes four levels of prioritized interrupts, independent programmable baud rate generators, and internal loopback capability for diagnostics. The component is housed in a 28-pin PLCC package.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix 'F' against official manufacturer documentation to confirm packaging or environmental specifications. Ensure the selected variant matches the required operating temperature range and package type for your design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when footprint compatibility with legacy SSI UARTs is required alongside enhanced features like lower access times. Consider the 1-byte FIFO limitation compared to higher-capacity models if large data throughput is necessary.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C1450 family of UARTs manufactured by Exar Corporation, now part of MaxLinear. The family includes variants such as the ST16C1450CQ48 and industrial temperature versions like the ST16C1450IJ28, offering different packages and temperature ranges.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C1450 is not compatible with industry standard 16450 devices. For MS Windows compatibility, consider the ST16C450. Direct replacements include other ST16C1450 variants with different packages or temperature ratings.
