PowerPC e200

The PowerPC e200 is a family of 32-bit Power Architecture microprocessor cores developed by Freescale for primary use in automotive and industrial control systems. The cores are designed to form the CPU part in system-on-a-chip (SoC) designs with speed ranging up to 600 MHz, thus making them ideal for embedded applications.

The e200 core is developed from the MPC5xx family processors, which in turn is derived from the MPC8xx core in the PowerQUICC SoC processors. e200 adheres to the Power ISA v.2.03 as well as the previous Book E specification. All e200 core based microprocessors are named in the MPC55xx and MPC56xx/JPC56x scheme, not to be confused with the MPC52xx processors which is based on the PowerPC e300 core.

In April 2007 Freescale and IPextreme opened up the e200 cores for licensing to other manufacturers.

Continental AG and Freescale are developing SPACE, a tri-core e200 based processor designed for electronic brake systems in cars.

STMicroelectronics and Freescale have jointly developed microcontrollers for automotive applications based on e200 in the MPC56xx/SPC56x family.

Cores

The e200 family consists of six cores, from simple low-end to complex high-end in nature.

e200z0

The simplest core, e200z0 features an in order, four stage pipeline with no MMU or FPU. It uses the variable bit length (VLE) part of the Power ISA, which uses 16-bit versions of the otherwise standard 32-bit PowerPC Book E ISA, thus reducing code footprint by up to 30%. It...
