1.4 Feature summary
• Dual-issue, 32-bit Power Architecture Book E compliant CPU core complex (e200z4d)
— Memory Management Unit (MMU)
— 4 KB, 2/4-way instruction cache
• 2 MB on-chip ECC flash memory with:
— Flash memory controller
— Prefetch buffers
• 64 KB on-chip ECC SRAM
• 1 MB on-chip non-ECC graphics SRAM with two-port graphics SRAM controller
• Memory Protection Unit (MPU) with up to 16 region descriptors and 32-byte region granularity to
provide basic memory access permission and ensure separation between different codes and data
• Interrupt Controller (INTC) with 181 peripheral interrupt sources and eight software interrupts
• Two Frequency-Modulated Phase-Locked Loops (FMPLLs)
— Primary FMPLL (FMPLL0) provides a system clock up to 125 MHz
— Auxiliary FMPLL (FMPLL1) is available for use as an alternate, modulated or non-modulated
clock source to eMIOS modules, QuadSPI and as alternate clock to the DCU and DCU-Lite for
pixel clock generation
• Crossbar switch architecture enables concurrent access of peripherals, flash memory or RAM from
multiple bus masters
• 16-channel Enhanced Direct Memory Access controller (eDMA) with multiple transfer request
sources using a DMA channel multiplexer
• Boot Assist Module (BAM) with 8 KB dedicated ROM for embedded boot code supports boot
options including download of boot code via a serial link (CAN or SCI)
• Two Display Control Units (DCU3 and DCULite) for direct drive of up to two TFT LCD displays
up to XGA resolution
• Timing Controller (TCON) and RSDS interface for the DCU3 module
• 2D OpenVG 1.1 and raster graphics accelerator (GFX2D)
• Video Input Unit (VIU2) supporting 8/10-bit ITU656 video input, YUV to RGB conversion, video
down-scaling, de-interlacing, contrast adjustment and brightness adjustment.
• DRAM controller supporting DDR1, DDR2, LPDDR1 and SDR DRAMs
• Stepper Motor Controller (SMC)
— High-current drivers for as many as six stepper motors driven in full dual H-bridge
configuration
— Stepper motor return-to-zero and stall detection module
— Stepper motor short circuit detection
• Sound Generator Module (SGM)
— 4-channel mixer
— Supports PCM wave playback and synthesized tones
— Optional PWM or I²S outputs
