HyperRAM Controller (Silicon Proven IP for Altera Devices)

Mobiveil Inc.

Select

HyperRAM™ controller IP for Winbond devices (x8/x16) with AXI memory-mapped access, APB control, RWDS strobes, linear/wrap/hybrid bursts, low-power modes, and device clocks up to 250 MHz for high bandwidth, low-pin designs. Technology-independent, system-validated RTL that enables smooth integration of Winbond HyperRAM into new-gen SoCs. Supports 8-bit and 16-bit data buses, RWDS read/write data strobes, AXI4 memory-mapped interface for data, APB for control, and linear, wrap, and hybrid bursts. Power features (deep power-down, hybrid sleep) are exposed via control/status registers. Delivered with SV/UVM testbench, behavioral PHY model, and a validated FPGA PHY reference design for rapid bring-up.
