概述

Description

IS21EF08G-JCLI is a serial NOR flash memory device (IS21EF family) used to store firmware and data in embedded systems. The “08G” generally indicates a high-density capacity (up to several gigabits, commonly 8Gbit in this family), and “JCLI” denotes the specific package/temperature variant of the device.
Key points
- Interface: SPI-compatible (standard flash commands; some variants offer Quad/SPi options)
- Features: Read/FAST READ, PAGE PROGRAM, SECTOR/ BLOCK ERASE, CHIP ERASE, WRITE ENABLE, status register, and low-power modes
- Usage: ideal for boot code, firmware storage, and data logging in microcontroller-based designs
- Package/variant: JCLI specifies the exact package type and temperature rating (check datasheet for pinout and electrical details)
Note
- Exact voltage range, timing, sector sizes, and command set should be confirmed from the official datasheet for your specific revision and package.

Package

IS21EF08G-JCLI is packaged in an 8-pin SOP (SOIC) package.

Pinout

- Pin count: 8 pins (8‑pin package, JCLI).
- Function: Serial non-volatile memory (EEPROM) accessible via a two‑wire interface (I2C); includes address pins A0–A2, WP (write protect), VCC, GND, SDA, and SCL.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI)
- What kind of company: A fabless semiconductor company that designs and markets memory and analog ICs (e.g., SRAM/DRAM/Flash memory and related analog products).

Application

Non-volatile memory for embedded systems. Typical applications:
- Storing firmware/boot code, calibration/config data
- Device IDs, labels, and feature flags
- Data logging for IoT sensors
- Memory expansion in consumer electronics
- Automotive and industrial control systems requiring reliable non-volatile storage

Equivalent

IS21EF08G-JCLI is an 8‑Mbit SPI‑NOR Flash in an 8‑pin package. Likely equivalents (same density and SPI interface) include:
- Winbond W25Q08JV/W25Q08V
- Macronix MX25L8006E
- Gigadevice GD25Q80B
- ISSI IS25LP080D
Note: verify voltage (Vcc), timing, and pinout in datasheets to ensure full compatibility.
