Description

The AT25256B-SSPDGV-T is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device offered by Microchip Technology. It features a storage capacity of 256 Kbits (32 Kbytes) and operates with a supply voltage ranging from 1.8V to 5.5V. The device communicates using a serial peripheral interface (SPI), enabling high-speed data transfer and efficient memory management.
Key features include a wide operating temperature range, low power consumption, and the ability to perform byte and page writes. It supports both read and write operations, making it suitable for applications where non-volatile data storage is crucial, such as in consumer electronics, automotive systems, and industrial equipment.
The "SSPDGV" in the part number denotes specific package and operational characteristics, with the "T" suffix indicating that the device is offered in tape-and-reel packaging for automated assembly. This EEPROM is ideal for applications requiring reliable and fast access to stored data.

Package

The AT25256B-SSPDGV-T is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) form factor.

Pinout

The AT25256B-SSPDGV-T is a 256 Kbit (32 K x 8) serial EEPROM device that operates using the SPI (Serial Peripheral Interface) protocol. It features a total of 8 pins. The pin configuration and functions are as follows:
1. CS (Chip Select): Activates the device.
2. MOSI (Master Out Slave In): Data input for writing to the EEPROM.
3. MISO (Master In Slave Out): Data output for reading from the EEPROM.
4. SCK (Serial Clock): Clock signal provided by the master device.
5. WP (Write Protect): Prevents write operations when held low.
6. VCC: Power supply pin, typically +2.7V to +5.5V.
7. GND: Ground reference pin.
8. HOLD: Pauses the serial communication without resetting the device state.
This device is commonly used for non-volatile data storage in various applications, including consumer electronics and industrial systems.
