2138D–HIREL–06/03
Supports flow through (register-buffer) synchronous burst SRAMs, pipelined
(register-register) synchronous burst SRAMs (3-1-1-1 or strobeless 4-1-1-1)
and pipelined (register-register) late-write synchronous burst SRAMs
L2 configurable to direct mapped SRAM interface or split cache/direct
mapped or private memory
