IS21TF08G-JQLI-TR

The IS21TF08G-JQLI-TR is a 64 Gbit non-volatile NAND flash memory device implemented as an eMMC package. It uses TLC NAND technology with an eMMC 5.1 interface and is organized as 8G × 8 to provide block-addressable embedded storage.

Designed for embedded storage integration, the device offers a 200 MHz clock frequency, a 2.7 V–3.6 V supply range, and a 100-LFBGA (14 × 18 mm) package, targeting systems that require moderate-capacity flash in a compact BGA footprint and a robust operating temperature range of −40 °C to 85 °C.

Key Features

• Memory Type & Technology  64 Gbit non-volatile NAND flash implemented with TLC technology for higher storage density in a single device.
• Memory Organization  Organized as 8G × 8 to present an 8-bit memory bus and support the stated capacity and interface implementation.
• Interface  eMMC 5.1 memory interface for standard embedded MMC connectivity and integration into host controllers that support eMMC.
• Performance  200 MHz clock frequency specification to define device timing parameters for host integration.
• Power Supply  Operates from a 2.7 V to 3.6 V supply range, supporting common system power rails for eMMC-based storage.
• Package  Supplied in a 100-LFBGA (14 × 18 mm) package, providing a compact BGA footprint for space-constrained PCBs.
• Operating Temperature  Rated for −40 °C to 85 °C ambient temperature, suitable for systems requiring extended temperature range operation.

Unique Advantages

• Higher storage density: 64 Gbit capacity in a single eMMC device reduces the need for multiple flash components.
• Standard eMMC interface: eMMC 5.1 simplifies host integration with defined MMC command sets and signal behavior.
• Compact BGA package: 100-LFBGA (14 × 18 mm) minimizes PCB area for embedded applications.
• Wide supply range: 2.7 V–3.6 V operation accommodates common system rails.
• Extended temperature operation: −40 °C to 85 °C rating supports designs that operate across broad ambient conditions.
• TLC NAND implementation: Enables higher raw bit density for cost-effective storage capacity.
