TC1130
The EBU is mainly used for the operation that masters on LMB bus access external
memories through EBU.
The EBU controls all transactions required for this operations and in particular handles
the arbitration of the external bus between multi-masters.
The types of external resources accessed by the EBU are:
• INTEL style peripherals (separate RD and WR signals)
• ROMs, EPROMs
• Static RAMs
• PC 100 SDRAMs (Burst Read/Write Capacity / Multi-Bank/Page support)
• Specific types of Burst Mode Flashes (Intel 28F800F3/28F160F3, AMD 29BL162)
• Special support for external emulator/debug hardware
Features
• Support Local Memory Bus (LMB 64-bit)
• Support External bus frequency: LMB frequency =1:1 or 1:2
• Highly programmable access parameters
• Support Intel-style peripherals/devices
• Support PC 100 SDRAM (burst access, multibanking, precharge, refresh)
• Support 16-and 32-bit SDRAM data bus and 64,128 and 256MBit devices
• Support Burst flash (Intel 28F800F3/160F3,AMD 29BL162)
• Support Multiplexed access (address &data on the same bus) when PC 100 SDRAM
is not implemented
• Support Data Buffering: Code Prefetch Buffer, Read/Write Buffer.
• External master arbitration compatible to C166 and other Tricore devices
• 4 programmable address regions (1 dedicated for emulator)
• Support Little-endian
• Signal for controlling data flow of slow-memory buffer
