IS21ES04G-JQLI

Memory IC Overview

The IS21ES04G-JQLI is a 4GB eMMC NAND flash memory device from ISSI, compliant with the eMMC 5.0 specification. It features an MLC configuration and supports bus modes including HS200 and HS400 at clock frequencies up to 200MHz. The component operates within a voltage range of 2.7V to 3.6V for VCC and 1.8V or 3.3V for VCCQ. It provides sequential read speeds of 272 MB/s and write speeds of 14.6 MB/s in 8-bit mode. The device includes boot partitions, RPMB support, and internal ECC. It is available in a 100-ball FBGA package (14mm x 18mm) and functions across industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via HS200 and HS400 modes with configurable bus widths of 1, 4, or 8 bits.
• Integrates internal error correction code (ECC) and enhanced data management algorithms for reliable operation.
• Includes dedicated Boot Partitions and Replay Protected Memory Block (RPMB) for secure data storage.
• Features field firmware update (FFU) capabilities and production state awareness mechanisms.

Memory IC Applications

• Industrial embedded storage solutions requiring wide temperature tolerance
• Automotive infotainment and control systems
• Consumer electronics utilizing standard eMMC interfaces

Memory IC Procurement Notes

Verify the specific suffix JQLI against the official datasheet to confirm the 100-ball FBGA package variant. Confirm that the required operating voltage aligns with the specified VCCQ options. Check current availability status as distribution channels may indicate limited stock or end-of-life transitions. Ensure the host controller supports the necessary eMMC 5.0 commands for initialization.

Memory IC Selection Notes

Select this component when a 4GB capacity is required alongside high-performance HS400 interface capabilities. Consider the 100-ball FBGA footprint if board space constraints differ from the 153-ball alternative. Verify that the host system can supply the required dual voltage rails for core and I/O operations. Evaluate the need for RPMB security features versus standard user data partitioning requirements.

Memory IC Part Context

This part belongs to the IS21/22ES04G series of eMMC devices manufactured by Integrated Silicon Solution Inc. The series is designed to meet JEDEC standards for embedded multimedia card applications. It integrates the NAND flash and controller into a single package to simplify host interface design. The product line targets markets demanding robust data retention and high-speed access in compact form factors.

Memory IC Replacement Considerations

IS21ES04G-JCLI-TR: Offers identical electrical specifications but utilizes a 153-ball FBGA package instead of the 100-ball variant. Ensure mechanical compatibility before substitution.

Memory IC FAQ
