JSL24G328WABQ-D25A-SU

Memory IC Overview

The JSL24G328WABQ-D25A-SU is a 4Gb LPDDR2 SDRAM manufactured by Jeju Semiconductor Corp, utilizing a 2Gb 2-stack architecture. It features an x32 interface with a maximum clock rate of 533MHz and a data rate of 1066Mb/s/pin for the -25A speed grade. The device operates within a temperature range of -40 to 85°C (Industrial). Power supplies are VDD1/VDD2 at 1.8V and VDDQ at 1.2V. Key specifications include 8 internal banks, double-data rate architecture, and differential clock inputs.

Memory IC Feature Summary

• Double-data rate architecture enabling two data transfers per clock cycle
• Bidirectional differential data strobes (DQS/DQS#) for precise data capture
• Supports Partial Array Self Refresh (PASR) and Temperature Compensated Self Refresh
• Configurable drive strength and auto precharge options

Memory IC Applications

• Mobile communication devices requiring high-speed memory
• Embedded systems needing low-power standby modes
• Portable electronics utilizing stacked memory configurations

Memory IC Procurement Notes

Verify the specific speed grade suffix (-25A vs -25) matches system timing requirements. Confirm the package option (10*11.5*1.0T) fits the PCB layout constraints. Ensure the industrial temperature rating (-40 to 85°C) aligns with the operational environment. Cross-reference the datasheet revision (Rev 1.3) for accurate initialization sequences.

Memory IC Selection Notes

Select this component for applications demanding high bandwidth in a compact form factor due to the 2-stack design. Consider the -25A grade for systems requiring 533MHz operation. Evaluate power consumption needs against the Deep Power Down and Self Refresh capabilities. Ensure the controller supports LPDDR2-S4 protocols and ZQ calibration commands.

Memory IC Part Context

This part belongs to the JSL24Gxx8WA-SU family of 4Gb LPDDR2 SDRAMs. It shares the same physical footprint and electrical characteristics with variants like the JSL24G328WABQ-D25-SU, differing primarily in speed grade and temperature rating. The 2-stack architecture allows higher density within standard BGA packages compared to single-die solutions.

Memory IC Replacement Considerations

JSL24G328WABQ-D25-SU: Same package and density but lower speed grade (400MHz). JSL24G328WABQ-D25M-SU: Industrial temperature rating with AT qualification.
