ST16C2450CJ44

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C2450CJ44 is a dual universal asynchronous receiver/transmitter (DUART) manufactured by MaxLinear, formerly Sipex. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 4 Mb/s. The device features two independent UART channels, each equipped with 16-byte transmit and receive FIFOs. It is housed in a 44-lead PLCC package and is designed for industrial temperature ranges from 0°C to +70°C. The component includes an Intel-compatible bus interface and supports standard serial communication protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by Sipex and Exar before being acquired by MaxLinear. Confirm the specific suffix 'CJ44' corresponds to the commercial temperature range and PLCC-44 package. Check current availability status as distribution channels may vary due to corporate restructuring and product lifecycle changes.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required within a single package footprint. Ensure the system design accommodates the 44-pin PLCC form factor. Verify that the 16-byte FIFO depth meets the throughput requirements of the application. Confirm compatibility with the target microcontroller's bus protocol, specifically Intel mode if applicable.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C2550/ST16C2450 family of DUARTs. The ST16C2450 typically offers standard performance levels compared to higher-end variants in the series. It serves as a bridge between parallel bus systems and serial communication lines, widely used in legacy and modern embedded designs requiring robust serial I/O capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements include the ST16C2550CJ44 for enhanced feature sets or the ST16C450CJ44TR for tape-and-reel packaging options. Verify electrical specifications match exactly, particularly voltage ranges and FIFO depths, before substituting.
