P82C08-10

Overview

The P82C08-10 is a Dynamic RAM (DRAM) memory controller IC manufactured by Altera. It is designed to manage 1M x 8 DRAM configurations and is housed in a 48-pin Dual In-line Package (DIP). This component serves as a dedicated interface for memory systems, facilitating data transfer between the processor and external DRAM modules.

Feature Summary

• Provides dedicated control logic for 1M x 8 DRAM architectures
• Interfaces with system buses via a 48-pin DIP package
• Supports standard DRAM timing and refresh cycles

Applications

• Embedded systems requiring dedicated DRAM management
• Industrial control units with legacy memory interfaces
• Communication equipment utilizing static DRAM banks

Procurement Notes

Verify the specific suffix '10' against official Intel/Altera documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints for 48-pin DIP packages. Confirm that the component meets required voltage levels and signal integrity standards for the target application environment before integration.

Selection Notes

Select this component when a dedicated hardware solution for 1M x 8 DRAM control is required rather than FPGA-based soft-core implementations. Consider the physical constraints of the 48-pin DIP package for through-hole mounting requirements. Evaluate system latency needs against the controller's fixed hardware performance capabilities.

Part Context

This part belongs to Altera's historical portfolio of discrete support chips used alongside their programmable logic devices. While modern designs often integrate such controllers into FPGAs or SoCs, this component remains relevant for legacy system maintenance and specific industrial applications requiring standalone memory control hardware.

Replacement Considerations

Direct substitutes may include other Altera memory controllers from the same era, such as the P82C08-16, though pinouts and capacities differ. Verify functional equivalence with third-party compatible parts if original stock is unavailable, ensuring all electrical and timing parameters match.
