Key features:
Exascend EM500 e.MMC undergoes a rigorous QC testing regimen during production, featuring an extensive wide-temperature burn-in test spanning from -40°C to 105°C. This testing surpasses commercial grade standards and guarantees that our wide temperature products will consistently operate reliably and perform optimally in extreme and rapidly fluctuating temperatures.
Exascend's power loss protection enables the flash storage device to quickly rebuild the mapping table when power is restored, ensuring seamless card functionality for the application.
By employing LDPC ECC and firmware read disturb protection, Exascend's e.MMC can achieve high levels of data integrity, ensuring that the data remains intact and reliable even in the presence of errors.
Exascend offers Secure Erase feature to guarantee swift and completely secure data deletion. Simultaneously, the Write Protection technology safeguards data stored on the flash storage device by configuring it into a read-only mode, effectively preventing the host device from altering or deleting any data.
