• Description: 32-bit Risc Microcomputer Superhtm Risc Engine Family / Sh7200 Series
• Manufacturer: Renesas Electronics Corporation.

The bus state controller (BSC) outputs control signals for various types of memory that is
connected to the external address space and external devices. BSC functions enable this LSI to
connect directly with SRAM, SDRAM, and other memory storage devices, and external devices.
8.1
1. External address space
2. Normal space interface
3. Burst ROM interface (clocked asynchronous)
4. MPX-I/O interface
5. SDRAM interface
 A maximum of 64 Mbytes for each of areas CS0 to CS8.
 Can specify the normal space interface, SRAM interface with byte selection, burst ROM
 Can select the data bus width (8, 16, or 32 bits) for each address space.
 Controls insertion of wait cycles for each address space.
 Controls insertion of wait cycles for each read access and write access.
 Can set independent idle cycles during the continuous access for five cases: read-write (in
 Supports the interface that can directly connect to the SRAM.
 High-speed access to the ROM that has the page mode function.
 Can directly connect to a peripheral LSI that needs an address/data multiplexing.
 Can set the SDRAM in up to two areas.
 Multiplex output for row address/column address.
 Efficient access by single read/single write.
 High-speed access in bank-active mode.
 Supports an auto-refresh and self-refresh.
 Supports low-frequency and power-down modes.
 Issues MRS and EMRS commands.
(clocked synchronous or asynchronous), MPX-I/O, burst MPX-I/O, SDRAM, and
PCMCIA interface for each address space.
same space/different spaces), read-read (in same space/different spaces), the first cycle is a
