TC1197
Introduction
2.5.8 External Bus Interface
The External Bus Unit (EBU) of the TC1197 controls the accesses from peripheral units
to external memories.
Features:
• 64-bit internal LMB interface
• 32-bit demultiplexed / 16-bit multiplexed external bus interface (3.3V, 2.5V)
– Support for Intel-style and Motorola-style interface signals
– Support for Burst Flash memory devices
– Flexibly programmable access parameters
– Programmable chip select lines
– Little-endian support
• Examples for memories that has to be supported
– Burst Flash:
– Spansion: S29CD016, S29CD032
– Spansion: S29CL032J1RFAM010 @3,3V
– ST: M58BW016, M58BW032
– ST: M58BW032GB B45ZA3T @3,3V
– Flash (for 16 bit muxed mode):

– IDT 71V416YS15BEI
• Scalable external bus frequency
– Derived from LMB frequency (f_CPU) divided by 1, 2, 3, or 4
– Maximum 75 MHz¹⁾
• Data buffering supported
– Code prefetch buffer
– Read/write buffer

On-Chip Debug Support (OCDS)
The TC1197 contains resources for different kinds of “debugging”, covering needs from
software development to real-time-tuning. These resources are either embedded in
specific modules (e.g. breakpoint logic of the TriCore) or part of a central peripheral
(known as CERBERUS).
