Description

The AT25040B-SSHL-T is a 4-Mbit (512K x 8) serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. It utilizes the I2C interface for communication, making it compatible with various microcontrollers and systems. The "SS" in the part number indicates a small-outline package, while "HL" signifies a lead-free and halogen-free design, aligning with environmental standards.
Key features include a wide operating voltage range (1.8V to 5.5V), low power consumption, and the ability to support multiple device addresses on the same bus. It offers 1,000,000 write/erase cycles and a data retention of up to 100 years, making it suitable for applications requiring reliable non-volatile storage, such as in consumer electronics, automotive, and industrial systems.
The AT25040B-SSHL-T is favored for its ease of integration, compact size, and robust performance in various electronic applications.

Package

The AT25040B-SSHL-T is packaged in a 8-pin SOIC (Small Outline Integrated Circuit) package. This surface-mount packaging is designed for easy integration into electronic circuits.

Pinout

The AT25040B-SSHL-T is a 5V, 4 Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) device produced by Microchip Technology. It features a total of 8 pins. The pin configuration and their functions are as follows:
1. CS (Chip Select): Active low input to select the device.
2. SO (Serial Output): The output data line for read operations.
3. SI (Serial Input): The input data line for write operations.
4. SCK (Serial Clock): Clock input for synchronizing data transfers.
5. VCC: Power supply pin (typically 5V).
6. GND: Ground reference pin.
7. HOLD: Input to pause the serial communication (active low).
8. WP (Write Protect): Input to enable or disable write protection (active low).
The AT25040B-SSHL-T uses a serial communication interface (SPI) for data transfer, making it suitable for applications requiring non-volatile memory storage.
