Manufacturer Part Number

25LC020AT-I/SN

Description

This is a 2Kbit EEPROM memory chip with SPI interface and fast 10 MHz clock speed. It is housed in an 8-pin SOIC package. It is non-volatile, so data remains after power loss. Works for data logging, code storage, or small configuration tasks.

Specifications

Memory size is 2 Kbit (256 x 8 bits). Communication is by Serial Peripheral Interface (SPI). Maximum clock frequency is 10 MHz. Page/word write cycle time is 5 ms. Voltage supply range is 2.5V to 5.5V. Operating temperature range is -40°C to 85°C. Surface mount package type is 8-SOIC. RoHS3 compliant. Moisture Sensitivity Level 1 (unlimited). Product status is Active.

Device Structure

The chip uses EEPROM technology for non-volatile memory storage. Organized as 256 words, with 8 bits per word. The main interface pins are for SPI data transfer, power, and control. Standard format 8-SOIC package makes it compatible with common PCB layouts.

Performance Characteristics

Fast SPI communication at up to 10 MHz for quick data transfer. Stable data retention without power. Reliable write/erase cycles. Works across wide voltage and temperature ranges so it’s suitable for robust applications. Write cycle time is quick at 5 ms per word/page. Has a verified programmable status which ensures its reliability in production systems.

Application Environments

Suitable for use in embedded systems, data acquisition, consumer electronics, industrial controls, and configuration storage. Used where non-volatile memory and simple SPI interfacing are needed. Good for environments between -40°C and 85°C such as industrial and automotive electronics.

Selection Guidelines

Choose this device if you need small capacity non-volatile memory with SPI interface. Make sure the voltage and current requirements in your circuit match the chip’s spec (2.5V~5.5V). Confirm the size (8-SOIC) fits your PCB layout. Suitable for repeated write/erase cycles and reliable long-term data retention.

Usage Considerations

Avoid exceeding voltage or temperature limits. Integrate with SPI controllers for proper communication. Follow ESD precautions during handling. Make sure your application’s memory needs fit the 2 Kbit storage size. This IC is RoHS compliant and has unlimited shelf life (MSL 1).
