The PXD20 represents a new generation of 32-bit
microcontrollers targeting single-chip industrial HMI
applications. PXD20 devices are part of the PX family of
Power Architecture -based devices. This family has been
designed with an emphasis on providing cost-effective and
high quality graphics capabilities.
®
PXD20 devices contain 2 MB internal flash memory. Serial
flash memory and DRAM interfaces are provided to allow
even greater system flexibility.

The PXD20:
•
•
•
Includes 2 MB internal flash memory, 1 MB internal
graphics SRAM, and 64 KB system SRAM
Offers high processing performance operating at
speeds up to 125 MHz
Is optimized for low power consumption
The PXD20 is designed to reduce development and
production costs of TFT-based displays by providing a
single-chip solution with the processing and storage capacity
to host and execute real-time application software and drive
TFT displays directly.
The PXD20 features a 2D OpenVG 1.1 graphics accelerator,
Video Input Unit (VIU2) and two on-chip display control
units (DCU3 and DCULite) designed to drive two color TFT
displays simultaneously. The PXD20 includes a enhanced
QuadSPI serial flash controller and an optional DRAM
controller allowing graphics RAM expansion externally.
The PXD20 is compatible with the existing development
infrastructure of current Power Architecture devices and are
supported with software drivers, operating systems and
configuration code to assist with application development.
