Mobiveil Inc.

Select

Ultra-high-speed OPI PSRAM controller for APMemory UHS devices (x8/x16), with Octal-SPI DDR, AXI4 memory-mapped access (with outstanding addresses), APB control, wrap & continuous burst modes, and device clocks up to 1066 MHz for low-power wearables/IoT and embedded systems. Technology-independent, system-validated RTL that integrates APMemory UHS PSRAM into SoCs/MPUs. Supports AP325608AOKx (8-bit) and AP325616AOKx (16-bit) devices, memory-mapped AXI4 data interface, APB control, DDR OPI transfers, wrap and continuous burst for efficient bandwidth, and an auto-initiate feature to reduce firmware overhead. Low-power controls (Global Reset, Self-Refresh, ZQ Cal) are exposed via CSRs. Package includes RTL, SV/UVM testbench, testcases, protocol checkers/bus watchers, and a reference PHY model for quick bring-up. Synthesis on DC/Genus; simulation on Xcelium/Questa/VCS.
