MT48LC2M32B2P-5:G

Memory IC Overview

The MT48LC2M32B2P-5:G is a Micron SDR SDRAM with 64 Mbit capacity, organized as 2 Meg x 32 across four internal banks. It operates at a maximum clock frequency of 200 MHz with a cycle time of 5 ns and access time of 15 ns (CL=3). The device uses an 86-pin TSOP II package and supports LVTTL-compatible I/O. It requires a single 3.3V ±0.3V power supply and functions within a commercial temperature range of 0°C to +70°C.

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
• Programmable burst lengths including 1, 2, 4, 8, or full page with auto precharge options
• Supports self-refresh mode and concurrent auto precharge with auto refresh modes

Memory IC Applications

• High-speed data buffering in computer systems
• Graphics memory applications requiring fast access times
• Embedded systems utilizing 3.3V logic interfaces
• Industrial control units operating within commercial temperature ranges

Memory IC Procurement Notes

Verify the specific revision suffix ':G' against current Micron documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the 86-pin TSOP II footprint aligns with your PCB layout constraints. Confirm that the 0°C to +70°C commercial temperature rating is sufficient for your operational environment, as industrial variants carry different suffixes.

Memory IC Selection Notes

Select this component when a 64 Mbit density with a 32-bit data bus width is required for synchronous memory applications. The 200 MHz speed grade suits designs needing low latency and high throughput. Verify compatibility with LVTTL logic levels and ensure the system provides a stable 3.3V power rail. Consider the physical dimensions of the 86-pin TSOP II package during mechanical integration.

Memory IC Part Context

This part belongs to the Micron MT48LC2M32B2 series of 64Mb SDR SDRAMs. It shares architectural features with other devices in the family but differs in timing parameters and packaging. The '-5' designation indicates the 200 MHz speed grade, while 'P' specifies the plastic TSOP II package type. The ':G' suffix denotes a specific manufacturing revision.

Memory IC Replacement Considerations

Direct replacements include MT48LC2M32B2P-5:J, which offers identical electrical performance but may differ in manufacturing revision details. For lower speed requirements, MT48LC2M32B2P-6A:G or MT48LC2M32B2P-7IT are compatible alternatives with relaxed timing specifications.
