A low-level RF controller has been developed for te accelerator controls for SuperKEKB, Super-conducting RF Test facility (STF) and Compact-ERL (cERL) at KEK. Te feedback mechanism will be performed on Vertex-V FPGA with 16-bit ADCs and DACs. Te card was designed as an advanced mezzanine card (AMC) for a MicroTCA shelf. An embedded EPICS IOC on te PowerPC core in FPGA will provide te global controls through channel access (CA) protocol on te backplane interconnect of te shelf. No other mechanisms are required for te external linkages. CA is exclusively employed in order to communicate with central controls and with an embedded IOC on a Linux-based PLC for slow controls.
