Introduction
1.1 The PXD20 microcontroller
The PXD20 represents a new generation of 32-bit microcontrollers targeting single-chip automotive
instrument cluster applications. PXD20 devices are part of the family of Power Architecture®-based
devices. This family has been designed with an emphasis on providing cost-effective and high quality
graphics capabilities in order to satisfy the increasing market demand for color Thin Film Transistor (TFT)
displays within the vehicle cockpit. Traditional cluster functions, such as gauge drive, real time counter,
and sound generation are also integrated on each device.
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 instrument cluster
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 and raster 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.
