A 400 MHz MPC5200 from an EFIKA computer.

The PowerPC e300 is a family of 32-bit PowerPC microprocessor cores developed by Freescale Semiconductor introduced in 2004. It was designed primarily for system-on-a-chip (SoC) designs with speed ranging up to 800 MHz,[1] thus making them ideal for embedded applications. It was one of the first products released by Freescale, which had formed as a spin-off of Motorola in 2004.[2]

The e300 is a superscalar RISC core with 16/16 or 32/32 kB L1 data/instruction caches, a four-stage pipeline with load/store,[3] system register, branch prediction[4] and integer unit with optional double-precision FPU.[5] The e300 core is completely backwards compatible with the G2 and PowerPC 603e cores from which it derives.[6]

The e300 core is the CPU part of several SoC processors from Freescale:

  • The MPC83xx PowerQUICC II Pro family of telecom and network processors.[7]
  • The MPC51xx and MPC52xx family of automotive and industrial control processors.[8]
  • MSC7120 GPON, optical network processor integrated DSP unit.[9]
