5.3. SDRAM Interface (SDB)
5.3.1. Summary
The SDRAM I/F Unit is a module belonging to the Bus Interface Unit (BIU) which functions as the interface between the
SS200 Core and external chip circuits, and it has the following functions:
(1) Has dedicated 64-bit data bus and 13-bit address bus pins.
(2) Performs external SDRAM address control, data transfer control, command control etc.
(3) Performs SDRAM transfers in 64-bit buses with burst length 4. Moreover, performs them wih burst length 8 in 32-bit
buses.
(4) CAS latency can be set from 1 to 3. Uses sequential burst type.
(5) Outputs 4 SCS (SDRAM Chip Select) signals.
(6) Auto-refresh and self-refresh settings supported.
(7) Performs SDRAM read and write operations in Burst Mode.
