AT28HC64B-12JU-T Typical application Circuitry

The AT28HC64B-12JU-T is a High-Speed CMOS Parallel EEPROM (Electrically Erasable Programmable Read-Only Memory) chip. Manufactured by Microchip Technology, it specializes in quick read and write cycles.

Applications

- Configuration Data Storage

- Industrial Automation

- Consumer Electronics

- Bootloaders for Microcontrollers

Key Features

- Data Capacity: 64K-bit

- Read Speed: 120ns

- Operating Voltage Range: 4.5V to 5.5V

- Data Endurance: Approximately 100,000 erase/write cycles

- Data Retention: Up to 40 years

Example Circuit: Configuration Data Storage for an IoT Device

Prerequisite Components:

- One AT28HC64B-12JU-T EEPROM chip

- Microcontroller (e.g., Arduino)

- 10kΩ Pull-up Resistors

- 0.1µF and 1µF Decoupling Capacitors

- 5V Power Source

Circuit Diagram

1. Supply Connection

- Connect the VCC pin (Pin 28) of the AT28HC64B-12JU-T to a stable 5V power source and GND (Pin 14) to the ground terminal.

2. Data Transfer Link

- The data pins, D0-D7 (Pins 11 to 18), should be tied to the data ports of your microcontroller for data read and write operations.

3. Memory Addressing

- Attach the Address Pins (Pins 1-9, 21-23) to the MCU's address bus. These are used to access different locations within the EEPROM.

4. Control Inputs

- For CE (Chip Enable), Pin 20 needs to be interfaced with an MCU's GPIO. A pull-up resistor of 10kΩ should be in place to ensure it defaults to a disabled state.

- OE (Output Enable) on Pin 22 has to be manipulated by the MCU for controlling data output.

- WE (Write Enable) at Pin 27 can be controlled by a separate GPIO on the MCU for initiating write cycles.

5. Noise Filtration

- Use a 0.1µF capacitor close to the VCC and GND pins for high-frequency noise suppression.

- Employ a 1µF capacitor in proximity to VCC and GND for mitigating low-frequency noise.

Design Considerations

- Supply Stability: Assure that the voltage levels do not exceed the AT28HC64B-12JU-T specifications.

- Timing Constraints: Pay close attention to the setup and hold times defined in the AT28HC64B-12JU-T data sheet to ensure data integrity.

- Noise Susceptibility: Use decoupling capacitors and proper grounding to minimize noise.

- Data Integrity: Ensure any write-protect features are set up to safeguard critical data.

By implementing these steps, the AT28HC64B-12JU-T can serve effectively as a reliable data storage component in your IoT device.
