Overview
The PowerPC 403GC 32-bit RISC embedded
controller offers high performance and functional
integration with low power consumption. The
403GC RISC CPU executes at sustained speeds
approaching one cycle per instruction. On-chip
caches and integrated DRAM and SRAM control
functions reduce chip count and design
complexity in systems, while improving system
throughput.
External I/O devices or SRAM/DRAM memory
banks can be directly attached to the 403GC bus
interface unit (BIU). Interfaces for up to eight
memory banks and I/O devices, including a
maximum of four DRAM banks, can be
configured individually, allowing the BIU to
manage devices or memory banks with differing
control, timing, or bus width requirements.
