TMS48C128-80DJ

Overview

The TMS48C128-80DJ is a high-speed Fast Page Dynamic Random Access Memory (DRAM) manufactured by Texas Instruments. It provides a total storage capacity of 1 Megabit, organized as 131,072 words of 8 bits each. The device features an access time of 80 nanoseconds and utilizes CMOS technology for power efficiency. It is housed in a 24-pin Plastic Dual Small Outline (PDSO24) package, suitable for surface-mount applications requiring compact memory solutions.

Feature Summary

• Implements Fast Page mode architecture for efficient sequential data access
• Utilizes CMOS technology to ensure low power consumption during operation
• Provides 8-bit data width with single-voltage supply requirements

Applications

• Embedded systems requiring non-volatile or volatile memory expansion
• Industrial control units needing compact DRAM storage
• Consumer electronics devices with limited board space

Procurement Notes

Verify the specific suffix '80DJ' to confirm the 80ns speed grade and PDSO24 package type. Ensure compatibility with existing system voltage levels and timing constraints before integration. Confirm RoHS compliance status if required for your manufacturing standards. Check for obsolescence notices from Texas Instruments as this component may be legacy.

Selection Notes

Select this part when a 128Kx8 organization is required with 80ns access speed. Compare against the TMS48C128-10DJ if a slower 100ns speed is acceptable for cost reduction. Consider the physical footprint of the PDSO24 package against available PCB real estate. Ensure the design supports the refresh requirements inherent to DRAM technology.

Part Context

This component belongs to the TMS48C128 series of Fast Page DRAMs. It shares architectural similarities with the TMS48C138 series but differs in density and organization. The device represents a standard solution for legacy microprocessor systems requiring reliable, high-speed random access memory within a small form factor.

Replacement Considerations

The TMS48C128-10DJ is a confirmed substitute offering identical functionality with a 100ns access time. Verify pinout compatibility and electrical specifications before swapping. No other direct cross-references are publicly documented for this specific part number.
