Visão Geral
Description
The EEPROM (Electrically Erasable Programmable Read-Only Memory) is used for storing small amounts of data that must be saved when power is removed. Common applications include consumer electronics, automotive systems, and industrial controls. These chips are often interfaced using I²C or SPI communication protocols.
In designing with such components, key considerations include memory size, voltage requirements, speed, and endurance (the number of write/erase cycles they can handle). For specific technical details or functionality, reviewing the datasheet from the manufacturer is essential, as it provides information on pin configurations, electrical characteristics, and usage guidelines.
Equivalent
1. Microchip Technology - 25LC320A or 25AA320A.
2. Atmel/Microchip - AT25320B.
3. ON Semiconductor - CAT25320.
Ensure compatibility by checking specifications like voltage range, temperature rating, and package type.
Features
Key features include:
1. Memory Organization: It offers 4,096 bytes of memory, organized as 512 pages of 8 bytes each.
2. Write Protection: The device includes hardware and software data protection mechanisms to safeguard against unintended writes.
3. Endurance and Retention: It supports up to 1 million write cycles per byte and a data retention period of up to 40 years.
4. Low Power Consumption: It features low power standby and deep power-down modes to optimize energy efficiency.
5. Temperature Range: Operates across a wide temperature range, ideal for industrial applications.
6. Packaging: Available in standard packaging options for easy integration into various designs.

Pinout
1. VCC (Pin 8): Power supply pin.
2. GND (Pin 4): Ground connection.
3. SCK (Pin 6): Serial Clock, used for clocking data in and out.
4. SI (Pin 5): Serial Input, for transferring data into the device.
5. SO (Pin 2): Serial Output, for transferring data out of the device.
6. CS (Pin 1): Chip Select, activates the device when low.
7. WP (Pin 3): Write Protect, used to protect against inadvertent write operations.
8. HOLD (Pin 7): Pauses communication with the device without resetting the operation.
These pins facilitate the communication and operation of the EEPROM with a microcontroller or processor over an SPI interface.
