Manufacturer:AD Description:Embedded MPC8xx core up to 100 MHz Maximum frequency operation of the external bus is 66 MHz The 50 MHz / 66 MHz core frequencies support both 1:1 and 2:1 modes. The 80 MHz / 100 MHz core frequencies support 2:1 mode only. Single-issue, 32-bit core (compatible with the PowerPC architecture definition) with 32 32-bit general-purpose registers (GPRs) The core performs branch prediction with conditional prefetch, without conditional execution. 4-Kbyte data cache and 4-Kbyte instruction cache C 4-Kbyte instruction cache is two-way, set-associative with 128 sets. C 4-Kbyte data cacheis two-way, set-associative with 128 sets. C Cache coherency for both instruction and data caches is maintained on 128-bit (4-word) cache blocks. C Caches are physically addressed, implement a least recently used (LRU) replacement algorithm, and are lockable on a cache block basis. MMUs with 32-entry TLB, fully associative instruction, and data TLBs MMUs support multiple page sizes of 4, 16, and 512 Kbytes, and 8 Mbytes; 16 virtual address spaces, and 16 protection groups Up to 32-bit data bus (dynamic bus sizing for 8, 16, and 32 bits) 32 address lines Memory controller (eight banks) Contains complete dynamic RAM (DRAM) controller Each bank can be a chip select or RAS to support a DRAM bank Up to 30 wait states programmable per memory bank Glueless interface to DRAM, SIMMS, SRAM, EPROMs, Flash EPROMs, and other memory devices DRAM controller-programmable to support most size and speed memory interfaces Four CAS lines, four WE lines, and one OE line Boot chip-select available at reset (options for 8-, 16-, or 32-bit memory) Variable block sizes (32 KbytesC256 Mbytes) Selectable write protection On-chip bus arbitration logic Fast Ethernet Controller (FEC) General-purpose timers Two 16-bit timers or one 32-bit timer Gate mode can enable or disable counting. Interrupt can be masked on reference match and event capture. |
