MICROCHIP TECHNOLOGY 可擦除编程只读存储器(EPROM) 25AA128-I/WF16K

25AA128-I/WF16K概述

    # Microchip 25AA128/25LC128 Serial EEPROM: A Comprehensive Overview
    1. Product Introduction
    The Microchip Technology Inc. 25AA128/25LC128 is a high-performance, serial electrically erasable programmable read-only memory (EEPROM) device that supports up to 128 kilobits (Kbit) of storage capacity. It is particularly well-suited for applications requiring non-volatile memory, such as embedded systems, automotive electronics, industrial controllers, and consumer electronics. The device operates via a simple Serial Peripheral Interface (SPI) protocol, making it highly compatible with various microcontrollers.
    Key Features:
    - Memory Structure: 16,384 x 8-bit organization.
    - Clock Speed: Maximum clock frequency of 10 MHz.
    - Write Characteristics: Supports 64-byte page writing with self-timed erase and write cycles.
    - Protection Mechanisms: Built-in write protection features including power-on/off data protection, write-enable latch, and write-protect pin.
    - Reliability: Endures up to 1 million erase/write cycles and maintains data retention for over 200 years.
    - Temperature Support: Qualified for automotive applications under AEC-Q100 standards and available in industrial and extended temperature ranges.
