AMD Eprom AM27C010-120DC 2 Megabit 256 kx8

The EEPROM 27256 is indeed a type of electrically erasable programmable read-only memory (EEPROM) chip, widely used for its non-volatile storage capabilities. Here’s a bit more detail about its features and applications:

### Key Features of EEPROM 27256

- **Storage Capacity**: 

  - **32 kilobits** (Kb) or **4 kilobytes** (KB), allowing it to store a significant amount of data.

- **Access Time**: 

  - Typically around **200 nanoseconds**, making it suitable for applications that require relatively fast access to stored data.

- **Packaging Options**: 

  - Commonly available in packages like DIP (Dual In-line Package) and surface mount configurations, providing flexibility for various circuit design needs.

- **Programming Method**: 

  - Requires specific programming equipment to write data, often involving higher voltages than standard logic levels for both writing and erasing operations.

- **Endurance and Reliability**:

  - Capable of withstanding approximately **100,000 write/erase cycles**, ensuring longevity in applications where frequent updates are necessary.

### Applications

The EEPROM 27256 finds its use in numerous applications such as:

1. **Embedded Systems**: For storing firmware or configuration settings that need to be retained after power loss.

2. **Consumer Electronics**: Used in devices requiring user-settings retention, like washing machines or microwaves.

3. **Automotive Applications**: Often utilized in vehicles for storing diagnostic information or calibration data.

4. **Industrial Equipment**: Employed in automation systems where parameters need to be preserved across resets.
