Overview
Description
IS21EF08G-JCLI is an 8‑Mbit SPI Serial NOR Flash memory from ISSI. It provides non‑volatile storage for embedded systems, commonly used for firmware (boot code) and data. It uses a standard SPI‑compatible interface and comes in an 8‑pin package (the JCLI code denotes the package variant). Typical features include support for common flash operations: Read, Page Program, Sector/Block Erase, Bulk Erase, and Write Enable/Disable, plus status/ID reads. It operates from a single supply suitable for serial flash devices and offers low‑power modes for energy‑efficient designs. This device is widely used wherever compact, durable on‑board storage is needed near a microcontroller. For exact timing, voltage range, endurance, and package details, consult the official datasheet.
Equivalent
Exact cross-references depend on the device type (SPI flash vs I2C EEPROM), capacity, voltage, and package. If IS21EF08G-JCLI is an 8-Mbit SPI flash, typical equivalents: Winbond W25Q08BV/W25Q08FW, Macronix MX25L0806E, GigaDevice GD25Q08C, ISSI IS25LP080D. If it’s an I2C EEPROM (e.g., 8K/16K): Microchip 24C08, Atmel 24C08, NXP 24C08. Please confirm interface and capacity for precise cross‑refs.
