Core advantage: the synergistic value of 1.8V low voltage and SLC high reliability
The greatest value of GD5F1GM7REYIGR in product design is concentrated in1.8V low voltage power supplywithHigh reliability of SLC architectureon the combination.
Compared with the 3.3V version, the operating voltage range of the 1.8V power supply version1.7V to 2.0V, in battery-powered IoT terminals, wearable devices and portable industrial instruments, it can be directly connected to the 1.8V logic level main control chip without the need for additional level conversion circuits, while significantly reducing the power consumption of the entire machine.This is particularly advantageous for devices that rely on long-term battery life.
SLC (single-layer cell) NAND flash memory only stores 1 bit of data per unit. Compared with MLC and TLC, its original bit error rate is lower and its erase and write life is longer.80K erasing and writing lifeand10 years of data retention, providing solid data integrity guarantee in scenarios such as industrial control and data collection that require frequent writing and long-term data storage.built-in8-bit ECC error correction engineData reliability is further strengthened.
Unlike traditional parallel NAND flash memory, which often requires more than 20 pins, this chip only requires6 SPI pinsAll communications can be completed, and the number of pins is greatly reduced, which not only reduces BOM costs, but also simplifies PCB design and manufacturing yield.At the same time, the chip supportsSoftware/hardware write protection, OTP area, deep power-down modeand other advanced features provide full protection for product firmware security and low-power standby.
As the leader in domestic storage, GigaDevice’s entire product process from wafer design to packaging and testing of finished products has been independently controllable in China, effectively reducing the risk of reliance on overseas memory chips in business negotiations and supply certainty.
