概要

Description

IS22EF08G-JCLA2 is a serial non-volatile memory device (EEPROM) from ISSI (Integrated Silicon Solution, Inc.) that uses a two-wire I2C/SMBus-compatible interface. It provides persistent storage for small data used by microcontrollers, such as configuration, calibration, IDs, or firmware metadata. It supports standard EEPROM features like byte-addressable reads, page write, and sequential reads, with low-power operation and data retention after power-down. Typical selection criteria include memory density, write cycle time, page size, addressing scheme, supply voltage range, temperature range, and package/pinout. For exact specs—capacity, timings, endurance, voltage windows, and packaging—refer to the official ISSI IS22EF08G-JCLA2 datasheet. If you share your target voltage, speed, and storage needs, I can help map those to the right operating conditions.

Features

IS22EF08G-JCLA2 is an 8‑Mbit serial (SPI) flash memory. Key features typically include:
- 8 Mbit serial flash density
- SPI-compatible interface
- Wide operating voltage: approx. 1.65 V to 3.6 V
- Fast read capability
- Page program (commonly 256 bytes)
- Sector/Block erase support
- Deep power-down and low‑power standby
- Write protection (WP) and hold features
- Status/ID registers for monitoring and protection
- Ready/Busy status indication
- Available in an 8-pin package (JCLA2) with standard JEDEC-compatible packaging
Note: exact timings, sector sizes, and voltage ranges should be confirmed in the official datasheet for this specific revision.

Package

Package type: 8-pin SOP (SOP-8), lead-free variant. For exact dimensions, check the datasheet.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8).
- Function: 8 kbit I2C serial EEPROM (2‑wire I2C interface) used for non-volatile data storage. Includes A0–A2 address pins and a WP (write‑protect) pin; pins include Vcc, GND, SDA, SCL, A0, A1, A2, WP.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI)
- What kind of company: A fabless semiconductor company that designs and markets memory ICs (e.g., SRAM, DRAM, NOR/serial flash) for various markets such as computing, consumer, automotive, and networking.

Application

IS22EF08G-JCLA2 is a serial I2C EEPROM (external non-volatile memory). Typical applications:
- Storing calibration data, device configuration, and serial numbers
- Data logging and event storage in embedded systems
- Firmware/config storage and memory expansion for microcontrollers
- Automotive, industrial, and consumer electronics needing reliable offline memory
- Asset tagging/ID memory for IoT sensors and wearables

Equivalent

To give exact equivalents, I need the device specs (memory type: SPI flash vs I2C EEPROM, capacity, voltage, package). If IS22EF08G-JCLA2 is an 8‑Mbit SPI serial flash in an 8‑pin package, common cross‑refs include Winbond W25Q80DV/BV, Macronix MX25L80, and GigaDevice GD25Q80B. For other densities or voltages, provide details and I’ll list precise cross‑refs.
