AY-3-1015D

Overview

The AY-3-1015D is a serial I/O controller manufactured by Microchip Technology, functioning as a Universal Asynchronous Receiver/Transmitter (UART). This component provides one UART channel and is housed in a 40-pin Dual In-line Package (PDIP). It serves as a dedicated interface solution for converting parallel data to serial format and vice versa, facilitating communication between microprocessors and peripheral devices. The device supports standard asynchronous serial protocols.

Feature Summary

• Provides a single UART channel for serial communication

Procurement Notes

Verify the specific package type and manufacturer documentation when sourcing this component. Ensure that the ordering suffix matches the required pin configuration and thermal characteristics. Confirm compatibility with the target system's voltage levels and signal integrity requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated hardware UART interface is required for reliable asynchronous data transmission. Consider the 40-pin PDIP form factor for through-hole mounting constraints. Evaluate the need for a single-channel serial interface versus multi-port solutions based on system architecture complexity.

Part Context
