MT48LC16M16A2F4-6A IT:GTR

Memory IC Overview

The MT48LC16M16A2F4-6A IT:GTR is a 256Mb Synchronous Dynamic Random Access Memory (SDRAM) component manufactured by Alliance Memory, Inc. It features an internal organization of 4 Meg x 16 across four independent banks. The device operates with a maximum clock frequency of 167 MHz and supports a cycle time of 6ns at CAS Latency 3. It utilizes a 54-ball VFBGA package measuring 8mm x 8mm. Electrical specifications include a single 3.3V ±0.3V power supply and an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Fully synchronous interface where all signals are 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 structure enabling interleaved operations to hide row access and precharge times.
• Supports programmable burst lengths including 1, 2, 4, 8, or full page with auto precharge capabilities.

Memory IC Applications

• High-performance embedded memory systems requiring synchronous data transfer.
• Industrial control applications necessitating operation within the -40°C to +85°C temperature range.
• Consumer electronics utilizing 3.3V logic levels and LVTTL-compatible interfaces.
• Portable devices benefiting from low-power modes such as self-refresh and power-down.

Memory IC Procurement Notes

Verify that the specific ordering suffix F4 corresponds to the 8mm x 8mm VFBGA package variant. Confirm the IT designation aligns with the required industrial temperature range of -40°C to +85°C. Ensure the GTR suffix matches the intended tape and reel packaging configuration for automated assembly processes. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints.

Memory IC Selection Notes

Select this component when a 256Mb density with a 16-bit data bus width is required. Choose this part for designs needing a 167 MHz operational speed with a 6ns cycle time. Opt for this package type if board space is limited due to its compact 8mm x 8mm footprint. Ensure the system voltage is compatible with the specified 3.3V ±0.3V requirement and LVTTL signaling standards.

Memory IC Part Context

This device belongs to the MT48LC16M16A2 series of 256Mb SDRAMs. It shares architectural similarities with other variants in the family, differing primarily in package type, timing speed grade, and environmental rating. The F4 suffix specifically denotes the small form-factor VFBGA package, distinguishing it from larger TSOP or standard FBGA options available in the same product line.

Memory IC Replacement Considerations

Direct substitutes may include other MT48LC16M16A2 variants with identical electrical characteristics but different packages, such as TG or BG suffixes. Verify pin compatibility and thermal requirements when considering alternative package types from the same manufacturer or cross-brand equivalents.
