Project Description

S282

MMC/eMMC Controller

  • S282 is a single-chip controller for MultiMediaCard (MMC). It was designed compliant with MMC Specifications from V3.3 to V4.5. S282 manages interface protocol, data storage and retrieval, error detection and correction, defect handling and diagnostic, as well as low power control. Besides standard form-factor SD cards, S282 fits RS-MMC cards and embedded MMC(eMMC) modules cards too.
  • Data Security: S282 is a distinguishing controller by providing extra hardware encryption & decryption modules to meet current market’s data security demands. These modules carry out world’s most popular algorithms such as AES.DES/3DES, etc. Since today’s eMMC module has been widely applied as micro-solid state disk in smart phones and tablet personal computers, S282 is actually providing low cost high reliability and user-friendly data security solutions for these applications by activating on-chip encryption/decryption functions.
  • Besides bare die or wafer delivered to the customers usually. S281 also can be shipped with LQFN46 or LQFP64 package.
