ST16C1551IJ28-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1551IJ28-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 1.5 Mbps. The device integrates 16-byte transmit and receive FIFOs to enhance throughput efficiency. It utilizes a 28-pin PLCC package and is rated for an industrial temperature range of -40°C to +85°C. The component features DMA support, interrupt generation capabilities, and compatibility with Intel and Motorola bus protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IJ28' confirms the industrial temperature grade (-40°C to +85°C) and PLCC-28 package variant against the official MaxLinear datasheet. Confirm RoHS compliance status as manufacturing processes may vary by production lot. Ensure the source document explicitly lists this exact part number to avoid confusion with similar commercial-grade or different package variants in the ST16C155x family.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with FIFO buffering is required for reliable asynchronous communication. The industrial temperature rating makes it suitable for harsh environments where commercial parts would fail. Verify that the system power supply remains stable between 2.97V and 5.5V. Consider the PLCC-28 footprint during PCB layout design to ensure adequate clearance and thermal management for surface-mount assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x series of UART controllers from MaxLinear (formerly Exar). The series offers various channel counts and package options. The ST16C1551 specifically denotes a single-channel configuration. It serves as a bridge between parallel microprocessor buses and serial data streams, commonly replacing older 16550-compatible designs with enhanced FIFO capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the ST16C155x family, such as the ST16C1551CIJ28 for commercial temperature ranges. Verify if alternative manufacturers offer compatible UARTs with identical FIFO sizes and voltage tolerances. Ensure any substitute maintains the same interrupt logic and DMA signaling requirements.
