GigaDevice Semiconductor Inc. has expanded its non-volatile memory portfolio with its first family of EEPROMs. The new GD24CL I²C EEPROM series offers high performance, comprehensive security, and high reliability that addresses the requirements long-term storage of critical configuration data. Target applications include industrial, energy, IoT, data centers, and networking.
The GD24CL series offers up to four million program/erase cycles. This is four times higher than the industry standard and enables reliable operation under frequent parameter update scenarios, according to the company. In addition, data retention is up to 100 years, ensuring long-term stability of stored information.
The devices also integrate a hardware-level error correction code (ECC) functionality, which significantly improve data integrity and system reliability, GigaDevice said.
The GD24CL series supports three clock frequency options of 100 kHz, 400 kHz, and 1 MHz, covering a wide range of applications from low-speed sensing devices to high-speed industrial control systems. The extended operating temperature range is -40°C to 125°C to support demanding applications.
The I2C EEPROMs support byte-level random read and write operations, making them suited for applications with frequent updates of small data parameters. It also delivers operational flexibility while further optimizing data write efficiency at the system level, according to GigaDevice.
For security, the GD24CL series integrates comprehensive hardware-based protection mechanisms to protect critical data assets. The devices include a write protect pin for the hardware write protection function and a write-lockable security page. “Once locked, the core data becomes permanently protected and non-writable, fundamentally eliminating the risk of data tampering and establishing a hardware-level data security barrier,” the company said.
Other key features include a wide operating voltage range from 1.7 V to 5.5 V, with standby current as low as 1 µA, read current as low as 1 mA, and write current as low as 1.5 mA. These low-power features make the series suited for industrial IoT terminals, green data centers, and other power-sensitive applications.
The series is available in several package options, including SOP8 (150 mil), TSSOP8 (173 mil), and UDFN8 2 × 3 mm.
GigaDevice expects to offer memory capacities from 32 Kb to 1 Mb. The GD24CL256B, a 256-Kb device, is the first product in this series with samples available now. It will be followed by 128-Kb and 512-Kb variants in the first half of 2027.
