HD3-6402R-9Z

Overview

The HD3-6402R-9Z is a CMOS Universal Asynchronous Receiver Transmitter (UART) manufactured by Renesas Electronics. It operates at frequencies up to 8.0 MHz, supporting baud rates up to 500 kbps. The device features a low-power CMOS design with power consumption reduced to 10 mW. It accepts a single +5 V power supply and provides CMOS/TTL compatible inputs. Key programmable parameters include data word lengths of 5, 6, 7, or 8 bits, selectable parity (odd or even), and one, one-and-a-half, or two stop bits. The component includes automatic data formatting and status generation logic.

Feature Summary

• Automatic data formatting and status generation for simplified user interface
• Programmable word length, stop bits, and parity settings
• Compatible with industry standard UART protocols
• Low power CMOS design utilizing advanced scaled SAJI IV process

Applications

• Modems
• Printers
• Peripherals
• Remote data acquisition systems

Procurement Notes

Verify the specific suffix '9Z' against official Renesas documentation to confirm package type, temperature range, and compliance status. Ensure the ordering code matches the required RoHS and Pb-free anneal specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when interfacing microprocessors to asynchronous serial channels requiring low power consumption and high noise immunity. The 8.0 MHz operating frequency supports baud rates up to 500 kbps. Consider the single +5 V supply requirement and CMOS/TTL input compatibility for system integration. Verify that the programmable frame format meets the specific communication protocol requirements of the target application.

Part Context

The HD3-6402R-9Z belongs to the HD-6402 series of CMOS UARTs produced by Renesas Electronics. This series is designed for computer and microprocessor interfacing with asynchronous serial data channels. The device integrates both transmitter and receiver functions, converting parallel data to serial form and vice versa, while handling start, parity, and stop bit generation and checking automatically.
