405GPr – Power PC 405GPr Embedded Processor
10
AMCC
Revision 2.04 – September 7, 2007
Data Sheet
Supports PCI target access to all PLB address spaces
Supports PowerPC processor boot from PCI memory
SDRAM Memory Controller
The PPC405GPr Memory Controller core provides a low latency access path to SDRAM memory. A variety of
system memory configurations are supported. The memory controller supports up to four physical banks. Up to
256MB per bank are supported, up to a maximum of 1GB. Memory timings, address and bank sizes, and memory
addressing modes are programmable.
Features include:
11x8 to 13x11 addressing for SDRAM (2- and 4-bank)
32-bit memory interface support
Programmable address compare for each bank of memory
Industry standard 168-pin DIMMS are supported (some configurations)
PC-133 support for 133 MHz memory
4MB to 256MB per bank
Programmable address mapping and timing
Auto refresh
Page mode accesses with up to 4 open pages
Power management (self-refresh)
Error checking and correction (ECC) support
- Standard single-error correct, double-error detect coverage
- Aligned nibble error detect
- Address error logging
External Peripheral Bus Controller (EBC)
Supports eight banks of ROM, EPROM, SRAM, Flash memory, or slave peripherals
Up to 66MHz operation
Burst and non-burst devices
8-, 16-, 32-bit byte-addressable data bus width support
Latch data on Ready
Programmable 2K clock time-out counter with disable for Ready
Programmable access timing per device
- 0–255 wait states for non-bursting devices
- 0–31 burst wait states for first access and up to 7 wait states for subsequent accesses
