A low-level RF controller has been developed for the accelerator controls for SuperKEKB, Super-conducting RF Test facility (STF) and Compact-ERL (cERL) at KEK. The feedback mechanism will be performed on Virtex-5 FPGA with 16-bit ADCs and DACs. The card was designed in the form-factor of an advanced mezzanine card (AMC) for a MicroTCA shelf. An embedded EPICS IOC on the PowerPC core in FPGA will provide the global controls through channel access (CA) protocol on the backplane interconnect of the shelf. No other mechanisms are required for the external linkages. CA is exclusively employed in order not only to make the AMC cards to communicate with each other, but also to communicate with central controls and with an embedded IOC on a Linux-based PLC for slow controls.
