TM124BBK32-80

Overview

The TM124BBK32-80 is a Fast Page Dynamic RAM (DRAM) module manufactured by Texas Instruments. It features a memory organization of 1 Megabit by 32 bits, providing a total capacity of 32 megabits. The component operates with an access time of 80 nanoseconds and utilizes CMOS technology for power efficiency. It is housed in a Single In-line Memory Module (SIMM) package with 72 pins, designated as SMA72. This module is designed for high-speed data storage and retrieval in computing systems requiring reliable volatile memory solutions.

Feature Summary

• Fast Page mode operation for efficient sequential data access
• CMOS technology ensuring low power consumption
• High-density 1Mx32 bit organization within a compact SIMM form factor

Applications

• Embedded computer systems requiring volatile memory expansion
• Industrial control units needing fast page DRAM modules
• Legacy computing hardware maintenance and upgrades

Procurement Notes

Verify the specific suffix -80 to confirm the 80ns speed grade and SMA72 package type. Ensure compatibility with existing motherboard SIMM slots supporting 5V or 3.3V logic levels as per system design. Confirm RoHS compliance status if required for modern manufacturing standards. Cross-reference the part number with official Texas Instruments documentation to avoid confusion with similar TM124 variants that may differ in speed or pin configuration.

Selection Notes

Select this module when a 1Mx32 bit density is required for system memory architecture. The 80ns access time suits applications where moderate speed is sufficient without the cost of faster SRAM. Consider the 72-pin SIMM physical constraints and ensure the target system supports Fast Page mode DRAM interfaces. Evaluate power requirements against the CMOS specifications to ensure adequate thermal management within the enclosure.

Part Context

This component belongs to the Texas Instruments TM124 series of dynamic RAM modules. These modules were widely used in personal computers and embedded systems during the era of 32-bit data buses. The TM124BBK32-80 specifically denotes the 80ns variant within this family, offering a balance between performance and cost for standard memory expansion needs in compatible hardware platforms.

Replacement Considerations

The TM124BBK32S-80 is a confirmed substitute part number from Texas Instruments with identical specifications.
