The IS21TF08G-JCLI from Integrated Silicon Solution Inc. (ISSI) is a high-performance 64Gb (8GB) managed NAND flash memory in an Embedded MultiMediaCard (eMMC) 5.1 interface package, designed for reliable embedded storage. It integrates a TLC NAND flash array with an advanced eMMC controller in a compact 153-ball VFBGA package (11.5x13mm), simplifying system design by handling complex flash management internally. Operating from a 2.7V to 3.6V supply and rated for the industrial temperature range of -40°C to +85°C, it supports a maximum clock frequency of 200 MHz and is compliant with eMMC specifications from version 4.3 to 5.1.
Its integrated controller manages essential NAND operations like wear leveling, bad block management, and error correction (ECC), significantly reducing host processor overhead and ensuring data integrity over extended program/erase cycles. It supports high-speed data transfer modes including HS200, enabling fast boot times and efficient data logging for real-time systems. The device offers flexible data bus widths (1-bit, 4-bit, and 8-bit) and features optional pseudo-SLC (pSLC) mode, which can be configured to enhance write endurance and reliability for high-write-intensity applications. Its robust thermal design and industrial-grade qualification ensure stable operation in harsh environments, making it suitable for automotive and industrial deployments.
The IS21TF08G-JCLI is engineered for embedded systems requiring reliable, high-density, and managed non-volatile storage. Its primary applications include industrial automation controllers (PLCs), factory machine vision systems, and IoT edge computing gateways. It is also ideal for automotive telematics and infotainment units, network communication equipment, and any consumer or industrial device where a simple, high-performance storage interface is critical.
