PowerPC 403GCX  
32-Bit RISC  
Data  
Sheet  
Embedded Controller  
Overview  
Features  
The PowerPC 403GCX 32-bit RISC embedded  
controller offers high performance and functional  
integration with low power consumption. The  
403GCX 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.  
PowerPC RISC CPU and instruction set  
architecture  
Glueless interfaces to DRAM, SRAM,  
ROM, and peripherals, including byte and  
half-word devices  
16KB instruction cache and 8KB write-  
back data cache, two-way set-associative  
Memory management unit  
–64-entry, fully associative TLB array  
–Variable page size (1KB-16MB)  
–Flexible TLB management  
External I/O devices or SRAM/DRAM memory  
banks can be directly attached to the 403GCX  
bus interface unit (BIU). Interfaces for up to eight  
memory banks and I/O devices, including a max-  
imum 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.  
Individually programmable on-chip  
controllers for:  
–Four DMA channels  
–DRAM, SRAM, and ROM banks  
–External interrupts  
DRAM controller supports EDO DRAM  
Flexible interface to external bus masters  
CPU core can run at 2X the external bus
