MICROCHIP TECHNOLOGY 带电可擦可编程只读存储器(EEPROM) 25AA128-E/ST

25AA128-E/ST概述

    # Microchip Technology's 25AA128/25LC128 Serial EEPROM Technical Overview
    Product Introduction
    The 25AA128/25LC128 from Microchip Technology is a 128-kilobit (16,384 x 8-bit organization) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). This product is designed to interface directly with the Serial Peripheral Interface (SPI) port of many modern microcontrollers, including Microchip's PIC series. It supports low-power CMOS technology, making it ideal for a wide range of applications where data storage and reliability are critical.
    Primary Features:
    - Maximum Clock Frequency: 10 MHz.
    - Operating Voltage: 1.8V to 5.5V.
    - Memory Organization: 16,384 x 8-bit.
    - Data Protection: Includes a write-protection mechanism and a power-on/off data protection circuitry.
    - Reliability: Endurance of up to 1,000,000 erase/write cycles and data retention of over 200 years.
    - Environmental Compliance: RoHS compliant and qualified under the automotive AEC-Q100 standard.

    Applications:
    - Embedded systems requiring non-volatile memory.
    - Industrial control systems.
    - Consumer electronics with need for reliable data storage.
    - Automotive electronics.
    Technical Parameters
    Electrical Characteristics:
    | Parameter | Minimum | Maximum | Unit | Condition |

    | Write Current | 5 | 10 | mA | At 5.5V, 10 MHz |
    | Read Current | 5 | 10 | mA | At 5.5V, 10 MHz |
    | Standby Current | 5 µA | At 5.5V |
    | Clock Frequency 10 | MHz
    | Internal Capacitance 7 | pF | At TA=25°C, CLK=1.0 MHz, VCC=5.0V |
    Operating Environment:
    - Temperature Range:
    - Industrial (I): -40°C to +85°C
    - Extended (E): -40°C to +125°C
    - Power Supply Voltage: 1.8V to 5.5V (Industrial) and 2.5V to 5.5V (Extended).
    Product Characteristics and Advantages
    Unique Features:
    - Self-Timed Erase and Write Cycles: Each operation takes a maximum of 5 ms, ensuring fast data access and minimal latency.
    - Block Write Protection: Offers granular protection options (none, 1/4, 1/2, or full array).
    - Built-In Write Protection: Includes a write-enable latch and a write-protect pin for added security.
    Key Benefits:
    - Reliability: With 1 million erase/write cycles and data retention beyond 200 years, it ensures long-term stability.
    - Energy Efficiency: Low standby current (5 µA) reduces power consumption in idle states.
    - Compatibility: Supports multiple packaging types (DFN, PDIP, SOIC, etc.) catering to various design requirements.
    Application Cases and Usage Suggestions
    Typical Use Cases:
    - Data Logging: Used in industrial sensors to log environmental data.
    - Automotive Applications: Suitable for storing calibration parameters in vehicles.
    - Embedded Systems: Ideal for storing configuration settings in consumer electronics.
    Implementation Tips:
    - Always ensure proper initialization by setting the write-enable latch before performing write operations.
    - Use the hold pin to temporarily suspend communication without losing the current sequence state.
    - Implement data backup routines to maintain data integrity across power cycles.
    Compatibility and Support
    Compatibility:
    - Microcontrollers: Compatible with most SPI-enabled microcontrollers, including Microchip's PIC series.
    - Packaging Options: Available in 8-lead DFN, PDIP, SOIC, SOIJ, and TSSOP formats, offering flexibility in PCB layouts.
    Support:
    - Documentation: Detailed technical documentation and application notes are available.
