TM124BBK32S-80

Overview

The TM124BBK32S-80 is a dynamic RAM module manufactured by Texas Instruments. It features a memory organization of 4 megabits by 32 bits, utilizing fast page mode operation. The component operates with an access time of 80 nanoseconds and utilizes the SMA72 interface standard. It is housed in a SIMM-72 package configuration.

Feature Summary

• Fast page mode dynamic RAM architecture
• SMA72 interface compatibility
• SIMM-72 physical form factor

Applications

• Legacy computer system memory expansion
• Industrial control systems requiring DRAM modules
• Embedded applications using SMA72 interfaces

Procurement Notes

Verify the specific suffix designation to confirm the 80ns access speed requirement. Ensure the procurement specification matches the SMA72 pinout and SIMM-72 mechanical dimensions. Confirm that the manufacturer source aligns with Texas Instruments documentation for this legacy part number.

Selection Notes

Select this component when a 4Mx32 bit capacity is required within a constrained physical footprint. The 80ns speed rating suits systems with moderate clock requirements. Verify compatibility with existing motherboard controllers supporting fast page mode DRAM before integration.

Part Context

This device belongs to the Texas Instruments line of dynamic RAM modules designed for older computing architectures. It serves as a memory solution for systems utilizing the SMA72 standard. The module provides non-volatile storage capabilities relative to power cycles but requires refresh cycles typical of DRAM technology.

Replacement Considerations

Compatible variants include the TM124BBK32S-60 and TM124BBK32S-70. These alternatives offer faster access times while maintaining the same memory organization and package type.
