MT48LC8M8A2TG-75 L:G

Memory IC Overview

The MT48LC8M8A2TG-75 L:G is a 64Mb Synchronous DRAM manufactured by Micron Technology. It features an 8-bit data bus width and is organized as 8 Meg x 8 with four internal banks. The component utilizes a 54-pin TSOP II package and operates on a single +3.3V power supply. It supports PC100 and PC133 standards, offering a cycle time of 7.5ns at CAS latency 3. Key operational modes include standard and low-power self-refresh, auto-refresh, and power-down.

Memory IC Feature Summary

• Fully synchronous interface with all signals registered on the positive edge of the system clock
• Internal pipelined architecture allowing column address changes every clock cycle for high-speed random access
• Quad-bank organization enabling concurrent operations to hide row access and precharge times
• Programmable burst lengths including sequential and interleaved types with full-page burst capability

Memory IC Applications

• High-performance personal computer memory systems
• Graphics cards requiring fast video memory bandwidth
• Embedded systems utilizing 3.3V logic levels
• Industrial control equipment operating within commercial temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the specific timing grade (-75), package type (TG for TSOP II), and environmental options (L for low-power self-refresh, :G for die revision). Confirm lead-free status if required by RoHS regulations. Ensure the supplier provides documentation confirming the component is from the authorized Micron Technology distribution channel to avoid counterfeit parts.

Memory IC Selection Notes

Select this part when a 64Mb density with an 8-bit interface is required in a 54-pin TSOP II form factor. The -75 speed grade is suitable for systems running at 133MHz with a CAS latency of 3. Consider the low-power self-refresh option if battery backup or extended standby periods are necessary. Verify compatibility with the target system's voltage requirements and signal integrity constraints for 3.3V LVTTL interfaces.

Memory IC Part Context

This component belongs to the Micron MT48LC8M8A2 family of 64Mb SDRAMs. It shares architectural similarities with the MT48LC16M4A2 and MT48LC4M16A2 variants, differing primarily in data bus width and bank organization. The device is designed to replace older asynchronous DRAMs in applications demanding higher throughput and lower latency through synchronous bursting capabilities.

Memory IC Replacement Considerations

Direct pin-compatible replacements may include other 64Mb SDRAMs in 54-pin TSOP II packages from different manufacturers, provided they support identical timing parameters and voltage levels. Cross-referencing mode register settings and initialization sequences is essential when substituting with non-Micron components.
