IS82C59A-12Z96

Specialized Overview

The IS82C59A-12Z96 is a CMOS priority interrupt controller manufactured by Renesas Electronics Corporation. It operates within a voltage range of 4.5V to 5.5V and supports clock frequencies up to 12MHz. The component is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package, suitable for surface mount technology. It functions as an I/O expander with peripheral interrupt control capabilities.

Specialized Feature Summary

• CMOS technology implementation for efficient power consumption
• Priority interrupt control functionality for managing multiple signal sources
• Surface mount compatible 28-pin PLCC packaging

Specialized Applications

• Peripheral interrupt controller systems
• I/O expansion modules
• General purpose digital interface circuits

Specialized Procurement Notes

Verify the specific suffix '96' against official Renesas documentation to confirm annealing requirements or process variations. Ensure compatibility with 5V logic levels and check for moisture sensitivity handling procedures during storage and assembly. Confirm availability status as distribution data may vary.

Specialized Selection Notes

Select this component when a dedicated hardware solution for prioritizing external interrupts is required. Consider the 28-PLCC package constraints for PCB layout. Verify that the 12MHz maximum frequency meets system timing requirements. Evaluate alternative packages if leaded chip carrier form factors are unsuitable for the target application.
