T2M Memory UHS-II Device Controller

UHS-II Device Controller

Description and Features

UHS-II is Ultra High speed type II controller for high speed transfers used in SD application for High definition contents. Key factors includes reusability of legacy resources, low voltage ,low power consumption and low EMI used in mobile devices. The type of connection topology supported by L&T’s UHS

  • Full Duplex Mode(FD mode) -Lane consists of one Transmitter port, Receiver Port and transmission clock. Data rate up to 156MB/s
  • Half Duplex with 2lanes mode(2L-HD Mode)-Changes the lane directions to 2lane mode during data transfer to achieve data rate up to 312MB/s.
