The PXN20 products are compatible 32-bit

technology. This document describes the available

features, and highlights important characteristics of the

devices.

The PXN20 products are designed to address the need

for single chip industrial networking applications and are

tailored to address the need for high performance and

high memory size while keeping the power consumption

low. Their core and bus architecture offer high

performance processing optimized for managing

intensive data exchanges between different types of

communication protocols. It capitalizes on the available

development infrastructure of current Power

software drivers and an operating system to assist with

users implementations.

The PXN20 devices have two levels of memory

hierarchy, a 32 KB unified cache, and 2 MB of internal

flash. The PXN20 has 592 KB on-chip L2 SRAM and
