AT28C256-15PU Typical application Circuitry

AT28C256-15PU

The AT28C256-15PU is an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip, recognized for its ease of use in data storage applications.

Application Scenarios

This EEPROM is commonly used in scenarios where a moderate amount of non-volatile data storage is required, with the ability to frequently update the stored data. Typical applications include firmware storage in consumer electronics, device configuration settings in industrial systems, data storage in automotive applications, and user preferences in various embedded systems.

Parameter Features

- Storage Capacity: The AT28C256-15PU offers 256 Kbits of storage space.

- Parallel Interface: It features a parallel interface for data input and output, enabling quick data access and ease of integration with microcontrollers and processors.

- Access Time: This EEPROM has an access time of 150 ns, providing quick data retrieval.

- Operating Voltage Range: Designed to operate within a 5V power supply range.

Specific Application Scenario: Configuration Data Storage in a Microcontroller-Based System

In a microcontroller-based system, such as a custom-built embedded system, the AT28C256-15PU can be used to store configuration data and operational parameters. Here's a detailed wiring guide:

1. Power Supply Connection: Connect the VCC pin of the AT28C256-15PU to a stable 5V power source, and the GND pin to the system's ground.

2. Data Pins Connection: Link the D0 to D7 (Data Input/Output) pins to the data bus of the microcontroller.

3. Address Pins Connection: Connect the A0 to A14 (Address Input) pins to the address bus of the microcontroller to select the desired memory location for reading or writing data.

4. Control Pins:

- The OE (Output Enable) pin should be connected to an output control line of the microcontroller to enable data reading from the EEPROM.

- The CE (Chip Enable) pin is used to activate the memory chip and should be connected to another control line of the microcontroller.

- The WE (Write Enable) pin controls data writing to the EEPROM and must be correctly interfaced with the microcontroller to allow data storage.

Circuit Design Considerations

- Voltage Compatibility: Ensure that the power supply voltage is consistent with the 5V requirement of the AT28C256-15PU.

- Data and Address Bus Configuration: Properly configure the data and address buses for accurate communication with the microcontroller.

- Write Protection: Implement appropriate measures to prevent unintentional writing to the EEPROM, especially during power transitions.

- Signal Integrity: Ensure clean and stable connections, especially for the control lines, to avoid data corruption.

In summary, the AT28C256-15PU is ideal in microcontroller-based systems for storing configuration data and operational parameters. Careful attention to voltage compatibility, bus configuration, write protection, and signal integrity is key to effectively integrating this EEPROM into such systems.
