Component Specifications

Definition
Electrically Erasable Programmable Read-Only Memory (EEPROM) is a type of non-volatile memory that retains stored data when power is removed. In communication protocol boards, it stores critical operational parameters, device addresses, calibration data, firmware updates, and communication settings. Unlike flash memory, EEPROM allows byte-level erasure and programming, making it ideal for frequent small data updates without requiring full chip erasure.
Working Principle
EEPROM operates using floating-gate transistors where data is stored by trapping electrons in an insulated gate. Electrical signals apply specific voltages to program (write), erase, or read memory cells. Data retention is achieved through charge isolation, while endurance depends on the number of write/erase cycles. Communication with the host system occurs via I2C, SPI, or parallel interfaces.

Silicon wafer substrate, polysilicon floating gate, oxide insulation layers (SiO2), aluminum or copper interconnects, ceramic or plastic packaging (DIP, SOIC, TSSOP).

Frequently Asked Questions

What is the difference between EEPROM and flash memory?

EEPROM allows byte-level erasure and programming, while flash memory requires block-level erasure. EEPROM typically has higher endurance cycles for small data updates.

How is data integrity maintained in EEPROM?

Through error correction codes (ECC), write protection features, and voltage monitoring circuits that prevent data corruption during power fluctuations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
