MT48LC4M16A2P-75 IT:G

The MT48LC4M16A2P-75 IT:G is a 64 Mbit synchronous DRAM (SDRAM) organized as 4M × 16 with a parallel memory interface. It is a fully synchronous, pipelined SDRAM device manufactured by Micron Technology Inc., offered in a 54-pin TSOP II package and specified for industrial temperature operation.

Designed for systems that require PC133-class parallel SDRAM storage in a compact 54‑TSOP (0.400", 10.16 mm) footprint, the device targets applications needing 3.3 V class supply operation and industrial ambient temperature range.

Key Features

• Memory Architecture 64 Mbit SDRAM organized as 4M × 16 with four internal banks and parallel DQ lines for byte/word access.
• Performance and Timing PC133-compliant operation with a 133 MHz clock frequency. Timing options include the -75 timing grade (7.5 ns cycle time at CL = 3); access time is listed as 5.4 ns and write cycle time (word/page) is 15 ns.
• Power Supply Single-supply operation at 3.3 V (specified 3.0 V to 3.6 V and documented as +3.3 V ±0.3 V in the datasheet).
• Package and Mounting 54-pin TSOP II (0.400", 10.16 mm width) plastic package for surface-mount board assembly.
• Temperature Range Industrial operating ambient range of −40°C to +85°C (TA), indicated by the IT marking.
• Synchronous and Pipelined Operation Fully synchronous design with all signals registered on the positive clock edge and internal pipelining allowing column address changes every clock cycle.
• Memory Management Features Internal bank architecture for hidden row access/precharge, programmable burst lengths (1, 2, 4, 8, or full page), auto precharge modes including concurrent auto precharge, and auto refresh.
• Refresh and Low-Power Modes Supports standard and low-power self-refresh modes and a 64 ms, 4,096-cycle refresh requirement.
• I/O Compatibility LVTTL-compatible inputs and outputs for interface interoperability with 3.3 V logic systems.

Typical Applications

• Industrial Embedded Systems — Memory expansion for controllers and embedded platforms that require operation across −40°C to +85°C.
• PC133-Class Memory Subsystems — Use in designs targeting PC66/PC100/PC133 timing compatibility where a PC133-capable SDRAM device is required.
• Board-Level DRAM Replacement — Direct replacement or upgrade in products using a 54-pin TSOP II SDRAM footprint and parallel memory interface.

Unique Advantages

• Industrial Temperature Rating: Specified for −40°C to +85°C operation, enabling deployment in temperature-challenging environments.
• PC133 Timing Support: 133 MHz clock capability and -75 timing grade (7.5 ns cycle time at CL = 3) provide compatibility with PC133-class memory systems.
• Compact TSOP II Package: 54-pin TSOP II (0.400") footprint allows high-density board-level integration in space-constrained designs.
• Flexible Burst and Refresh Control: Programmable burst lengths, auto-precharge options and self-refresh modes simplify memory controller design and support power management strategies.
• Single 3.3 V Supply: Operation from a single 3.0 V–3.6 V supply streamlines power rail requirements for 3.3 V logic systems.
• Manufacturer Documentation: Full technical datasheet and device documentation are available from the manufacturer for design validation and integration.
