IS21TF08G-JCLI

Memory IC Overview

The IS21TF08G-JCLI is an 8GB eMMC NAND flash memory device compliant with the eMMC 5.1 specification, manufactured by ISSI. It utilizes TLC NAND technology configured in pSLC mode within a 153-ball FBGA package measuring 11.5mm x 13mm x 1.0mm. The component operates on a VCC supply of 2.7V to 3.6V and supports VCCQ levels of 1.8V or 3.3V. It features sequential read speeds up to 320 MB/s and write speeds up to 135 MB/s using HS400 mode. The device functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Integrates pSLC Mode NAND with an embedded eMMC controller for direct host interface management
• Supports high-speed data transfer via HS200 and HS400 modes with command queuing capabilities
• Includes internal error correction code (ECC) and enhanced data management algorithms
• Provides secure erase, trim commands, and permanent/partial write protection options

Memory IC Applications

• Industrial embedded storage solutions requiring wide operating temperatures
• Automotive application storage systems
• High-performance mobile devices and consumer electronics

Memory IC Procurement Notes

Verify current manufacturing status directly with ISSI as availability may vary. Confirm specific voltage requirements (VCCQ 1.8V vs 3.3V) match your system design before ordering. Ensure compliance with RoHS and REACH regulations if required by your region. Check for any specific automotive grade certifications if deploying in A1 or A2 environments.

Memory IC Selection Notes

Select this model when an 8GB capacity with eMMC 5.1 compatibility is required. Choose the 153-ball FBGA package for standard footprint integration. Consider the pSLC configuration for improved endurance compared to standard MLC/TLC operations. Verify that the host controller supports HS400 signaling if maximum throughput is needed.

Memory IC Part Context

This component belongs to the IS21/22TF08G series from Integrated Silicon Solution Inc. It is part of a family of eMMC products designed for embedded applications. The TF suffix typically denotes the specific NAND technology and capacity tier within the ISSI portfolio, distinguishing it from other density or interface variants.

Memory IC Replacement Considerations

IS22TF08G-JCLI is a compatible alternative within the same series offering identical specifications and pinout compatibility.
