P82C088

Overview

The P82C088 is a Dynamic RAM (DRAM) controller manufactured by Altera, designed for reliable management of dynamic memory systems. It operates within an operating supply voltage range of 4.5V to 5.5V and supports a data configuration of 1M x 8 bits. The component is rated for an operating temperature range of 0°C to 70°C (TA). It utilizes a through-hole mounting type and is housed in a 48-DIP package case.

Feature Summary

• Provides dedicated control logic for Dynamic RAM (DRAM) operations
• Supports standard CMOS technology for interface compatibility
• Designed for robust memory management in industrial environments

Applications

• System designs requiring external DRAM expansion
• Industrial control systems with through-hole board constraints
• Legacy embedded architectures utilizing 5V logic levels

Procurement Notes

Verify the specific revision level against the manufacturer's latest documentation, as older components may have undergone labeling or minor specification updates. Confirm that the 48-DIP through-hole package aligns with your PCB footprint requirements. Ensure the 4.5V to 5.5V supply voltage matches your system power rails. Check for any end-of-life notices or alternative recommendations from Intel/Altera for current production cycles.

Selection Notes

Select this component only if a discrete DRAM controller solution is required rather than an integrated FPGA or SoC approach. The 48-DIP package limits usage to prototyping or legacy manufacturing processes. Ensure the design accommodates the 0°C to 70°C commercial temperature range. This part is suitable for applications where board space allows for through-hole mounting and where separate memory controller logic is preferred over internal block RAM.

Part Context

The P82C088 belongs to Altera's historical portfolio of discrete programmable logic and peripheral controllers. It represents an era before high-density FPGAs integrated extensive memory controllers on-chip. As a standalone device, it facilitates memory interfacing for custom digital designs. Its existence highlights the evolution from discrete controller chips to highly integrated System-on-Chip solutions offered by modern Intel FPGA families.
