25AA128T-I/ST Typical application Circuitry

The 25AA128T-I/ST is a 128 Kbit Serial Electrically Erasable PROM (EEPROM) chip that uses the Serial Peripheral Interface (SPI) protocol for communication.

Parameter Specifications of 25AA128T-I/ST

- Data Rate: Can achieve up to 10 MHz.

- Voltage Requirements: Ranges between 1.7V to 5.5V.

- Data Retention: Data can be retained for over 200 years.

- Write Endurance: 1 million erase/write cycles.

Applicability in Real-World Scenarios

The 25AA128T-I/ST finds use in a multitude of applications, from simple data logging devices to complex embedded systems requiring secure and durable storage.

Design Considerations

- Compatibility: Ensure voltage compatibility between the EEPROM and the microcontroller.

- Signal Quality: Maintain short lead lengths to preserve signal integrity.

- Power-Up Sequencing: Confirm proper power-up sequences to avoid unintentional writes.

Example Circuit: Data Logging Device

Circuit Connection Details

1. Power Supply Configuration

- VCC: Pin 8 serves as the power supply pin. Connect it to a source ranging from 1.7V to 5.5V.

- VSS: Ground your circuit at Pin 4.

2. SPI Setup

- CS (Chip Select): Pin 1 will connect to the Chip Select (CS) output of your MCU.

- SO (Serial Output): Link Pin 2, which is the data output, to the MCU's Master In Slave Out (MISO) pin.

- SI (Serial Input): Pin 5 will connect to the Master Out Slave In (MOSI) pin of your MCU.

- SCK (Clock): Pin 6 should be wired to your MCU's clock pin.

3. Write Protection

- WP (Write Protect): Utilize Pin 7 for hardware write protection. When connected to ground, it enables write operations; connect it to VCC to disable writing.

4. HOLD Pin

- HOLD: Pin 3 can be used to pause the SPI bus without deselecting the device. Connect it to the MCU's I/O pin or leave it unconnected if not in use.

By adhering to these guidelines, the 25AA128T-I/ST can be effectively utilized in your data logging device, ensuring reliable data storage and handling.
