T2M MIPI MIPI ASPMI Slave Controller IP

MIPI ASPMI Slave Controller IP

Description and Features

MIPI ASPMI Slave interface provides full support for the two-wire MIPI ASPMI synchronous serial interface, compatible with SPMI specification. Through its SPMI compatibility, it provides a simple interface to a wide range of low-cost devices. MIPI ASPMI Slave IP is proven in FPGA environment. The host interface of the MIPI ASPMI can be simple interface or can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXl-Lite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol. MIPI ASPMI Slave IP is supported natively in Verilog and VHDL
