s351 Memory Module; Virtex-II Pro FPGA XC2VP7;

The SMT351 is a single width TIM compatible module populated with hi-density BGA package memory devices that is able to store up to 1GB of data at 400MB/s. The SMT351 can be cascade with more modules for even greater memory storage capability.

The data flows in and out of the module are controlled by a Xilinx Virtex-II Pro FPGA XC2VP7. Connections to the module are made by two Sundance High-speed Bus (SHB) connectors. This bus is compatible with other Sundance TIMS.

Control of the SMT351 is achieved by sending control words via comport.

s351btmFour TTL I/Os and four LEDs are available for general purpose.
