MPC8241LVR166D

The MPC8241 Integrated Host Processor fits applications where cost, space, power consumption and performance are critical requirements. This device provides a high level of integration, reducing chip count from five discrete chips to one, thereby significantly reducing system component cost. High integration results in a simplified board design, less power consumption and a faster-time-to-market solution. This cost-effective, general purpose integrated processor targets systems using PCI interfaces in networking infrastructure, telecommunications, and other embedded markets. It can be used for control processing in applications such as routers, switches, network storage applications and image display systems.

• Major features of the MPC8241 are as follows:
  • High-performance, superscalar processor core
  • Integer unit (IU), floating-point unit (FPU) (software enabled or disabled), load/store unit (LSU), system register unit (SRU), and a branch processing unit (BPU)
  • 16-Kbyte instruction cache
  • 16-Kbyte data cache
  • Lockable L1 caches—entire cache or on a per-way basis up to three of four ways
  • Dynamic power management—supports 60x nap, doze, and sleep modes
  • Peripheral logic
  • Peripheral logic bus
  • Various operating frequencies and bus divider ratios
  • 32-bit address bus, 64-bit data bus
  • Full memory coherency
  • Decoupled address and data buses for pipelining of peripheral logic bus accesses
