PPC405EP – PowerPC 405EP Embedded Processor
Revision 1.07 – September 10, 2007
Data Sheet
AMCC
9
SDRAM Memory Controller
The PPC405EP 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 two physical banks. Up to
256MB per bank are supported, up to a maximum of 512MB. Memory timings, address and bank sizes, and
memory addressing modes are programmable.
Features include:
11x8 to 13x11 addressing for SDRAM (2 banks)
32-bit memory interface support
Programmable address compare for each bank of memory
Industry standard 168-pin DIMMS are supported (some configurations)
Up to 133MHz memory supported by the 266MHz processor
Up to 111MHz memory supported by the 333MHz processor
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)
External Peripheral Bus Controller (EBC)
Supports five banks of ROM, EPROM, SRAM, Flash memory, or slave peripherals
Up to 66MHz operation
Burst and non-burst devices
8- and 16-bit byte-addressable data bus width support
Latch data on Ready, synchronous or asynchronous
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
- Programmable CSon, CSoff relative to address
- Programmable OEon, WEon, WEoff (0 to 3 clock cycles) relative to CS
Programmable address mapping
Peripheral Device pacing with external “Ready”
DMA Controller
Supports memory-to-memory transfers
Four channels
Scatter/gather capability for programming multiple DMA operations
32-bit addressing
Address increment or decrement
Internal 32-byte data buffering capability
