Overview
The AY-5-1013A-HR is a legacy Universal Asynchronous Receiver Transmitter (UART) integrated circuit manufactured by Microchip Technology. It features an eight-channel architecture with parallel data input and output capabilities, housed in a 40-pin Dual In-line Package (DIP). The device supports asynchronous serial communication protocols, providing dedicated transmit and receive lines for each channel to facilitate multi-port connectivity in embedded systems.
Feature Summary
- Supports eight independent UART channels within a single package
- Utilizes parallel data interface for direct CPU or microcontroller bus integration
- Provides dedicated transmit and receive signal paths per channel
Applications
- Multi-port serial communication interfaces
- Legacy system data acquisition modules
- Industrial control panel connectivity
Procurement Notes
Verify the specific suffix 'HR' against the official Microchip datasheet to confirm pinout compatibility and voltage levels. Ensure the 40-PDIP package matches the target PCB footprint. Confirm that the parallel interface requirement aligns with the host controller's available data bus width before procurement.
Selection Notes
Select this component when a high-density UART solution with parallel interface is required. It is suitable for applications needing multiple serial ports without consuming excessive board space. Consider the legacy nature of the parallel interface and ensure the host system supports the necessary control signals for channel selection and data latching.
Part Context
This part belongs to Microchip's line of UART controllers, designed for reliable serial data transmission. It serves as a bridge between parallel processor buses and asynchronous serial devices, commonly used in environments requiring robust, standalone serial communication hardware.
Replacement Considerations
Consult Microchip documentation for direct cross-reference parts. Legacy UART replacements may require interface adaptation due to differences in control logic or pin configurations.
