AT25128B-XHL-T Typical application Circuitry

AT25128B-XHL-T

Electrically Erasable Programmable Read-Only Memory (EEPROM) hardware from Microchip Technology has a serial interface and 128 KB of capacity. This chip provides non-volatile storage, meaning the data it holds is preserved even when power is removed. It communicates via an SPI (Serial Peripheral Interface) bus, making it ideal for use in various applications like data logging, configuration settings, and storing user preferences.

Consider a scenario where the AT25128B-XHL-T is used to store configuration settings in an embedded system:

- The Chip Select (CS, Pin 1) needs to be connected to a GPO pin on the microcontroller (MCU). The MCU uses this line to enable the AT25128B-XHL-T when it needs to read or write data.

- The Serial Clock (SCK, Pin 6) should be connected to the SPI clock line on the MCU. The SCK line is used to synchronize data transfer between the MCU and the EEPROM.

- The Serial Data Input (SI, Pin 5) and Serial Data Output (SO, Pin 2) are connected to the SPI data lines on the MCU. SI is used to send data to the EEPROM, and SO is used to read data from it.

- The Write Protect (WP, Pin 3) pin can be used to prevent data from being written to the EEPROM. If this feature is not required, WP can be connected to the ground (VSS, Pin 4).

- The Hold (HOLD, Pin 7) pin is used to pause data transfer without resetting the serial sequence. If not used, this pin should be connected to VCC (Pin 8).

In designing circuits with the AT25128B-XHL-T, several considerations need to be made:

1. Power Supply: The EEPROM operates from 1.8V to 5.5V. Decoupling capacitors need to be put close to the VCC pin in order to keep the power supply voltage constant.

2. SPI Bus: Care must be taken when using the SPI bus, especially in a multi-device setup. The CS pin enables specific devices, and thus each device on the bus needs a separate CS line.

3. Write Cycles: The EEPROM has a maximum number of write cycles (typically in the millions). If your application requires frequent data updates, this could limit the device's lifetime.

4. Write Protection: If critical data is stored on the EEPROM, you might want to utilize the WP pin to prevent accidental data changes.

In summary, the AT25128B-XHL-T is a valuable addition to any system requiring non-volatile data storage, due to its high capacity, versatility, and ease of use.
