Signals
The TLU SRAM interface supports up to 32MBytes of SRAM at frequencies to 133MHz
using LVTTL signaling levels (in single bank-mode only) and SRAM technologies up to
64Mbits. The TLU SRAM interface signals are described in

SIGNAL DESCRIPTION
Clock: MDCLK is driven by the system clock. All
SDRAM input signals are sampled on the positive
edge of the MDCLK. MDCLK also increments the
internal burst counter and controls the output
registers.
