ISL6402IR

Overview

The ISL6402IR is a CMOS Universal Asynchronous Receiver/Transmitter (UART) designed for interfacing microprocessors to asynchronous serial data channels. It operates with supply voltages ranging from 3.0V to 5.5V and supports clock frequencies up to 8.0MHz, corresponding to baud rates of 500K. The device features an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Converts parallel data into serial format with automatic start, parity, and stop bit generation
• Receiver converts incoming serial bits including start, data, parity, and stop configurations
• Configurable data word lengths of 5, 6, 7, or 8 bits with selectable odd or even parity
• Utilizes advanced SAJI IV CMOS process for low power consumption compared to legacy devices

Applications

• Modems
• Printers
• Remote data acquisition systems

Procurement Notes

Verify the specific suffix 'IR' indicates the industrial temperature grade (-40°C to +85°C) and SOIC-8 package configuration. Confirm that the component is sourced from Intersil or authorized Renesas distributors to ensure authenticity. Check for RoHS compliance status as manufacturing processes may vary by production batch.

Selection Notes

Select this UART when interfacing microprocessors to asynchronous serial channels requiring high clock speeds up to 8.0MHz. It is suitable for applications demanding reduced power consumption while maintaining flexible data word lengths and parity options. Consider the SOIC-8 footprint for PCB layout constraints.

Part Context

The ISL6402 belongs to the HD-6402 family of UARTs manufactured by Intersil. These components are designed to bridge microprocessors and serial data channels efficiently. The series utilizes scaled CMOS technology to achieve significant power reductions while supporting standard communication protocols.
