MT53E256M32D1KS-046 WT:L

Memory IC Overview

The MT53E256M32D1KS-046 WT:L is a mobile LPDDR4 SDRAM device with an 8 Gbit capacity, organized as 256M x 32. It operates at a maximum clock frequency of 2.133 GHz and utilizes a VFBGA package with 200 pins. The component supports a data rate range of 4266–20 Mb/s per pin and functions within a voltage range of 1.06 V to 1.95 V. It features a 16n prefetch DDR architecture with eight internal banks per channel for concurrent operation. The device includes programmable read/write latencies and burst lengths, along with on-chip temperature sensing for self-refresh control.

Memory IC Feature Summary

• Supports low-power DDR4 protocol with double-data-rate transfers on the DQ bus
• Features bidirectional differential data strobes per byte lane for high-speed signaling
• Includes on-chip temperature sensor to regulate self-refresh rates dynamically
• Enables partial-array self-refresh and directed per-bank refresh for power optimization

Memory IC Applications

• Mobile smartphones and tablets requiring high-density memory
• Wearable devices with strict power consumption constraints
• Automotive infotainment systems operating in extended temperature ranges
• IoT gateways and edge computing modules

Memory IC Procurement Notes

Verify the specific suffix 'WT:L' against official Micron documentation to confirm temperature grade and speed bin alignment. Confirm current production status as availability may vary by region. Ensure compatibility with host controller LPDDR4 PHY settings before integration. Request latest datasheet revision to validate electrical characteristics and mechanical dimensions.

Memory IC Selection Notes

Select this component when an 8 Gbit density with a 32-bit interface width is required for mobile applications. The 200-pin VFBGA package suits space-constrained designs. Verify that the host system supports the 2.133 GHz maximum frequency and compatible voltage levels. Consider thermal management requirements given the operational temperature range and self-refresh capabilities.
