PXD20 416 TEPBGA 27 mm x 27 mm 176 LQFP 24 mm x 24 mm 208 LQFP 28 mm x 28 mm © Freescale Semiconductor, Inc., 2011–2012. All rights reserved. Preliminary—Subject to Change Without Notice 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.
