Overview
1.3 Feature list
⢠Dual-issue, 32-bit Power Architecture Book E compliant CPU core complex (e200z4d)
â Memory Management Unit (MMU)
â 4 KB, 2/4-way instruction cache
⢠2 MB on-chip ECC flash memory with:
â Flash memory controller
â 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)
â Primary FMPLL (FMPLL0) provides a system clock up to 125 MHz
â 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

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)
â High-current drivers for as many as six stepper motors driven in full dual H-bridge configuration
â Stepper motor return-to-zero and stall detection module
â Stepper motor short circuit detection
⢠Sound Generator Module (SGM)
â 4-channel mixer
â Supports PCM wave playback and synthesized tones
â Optional PWM or I2S outputs
⢠Two 16-channel Enhanced Modular Input Output System (eMIOS) modules
â Support a range of 16-bit Input Capture, Output Compare, Pulse Width Modulation and Quadrature Decode
functions
⢠10-bit Analog-to-Digital Converter (ADC) with a maximum conversion time of 1 ïs
â Up to 20 internal channels
â Up to 8 external channels
⢠Three Deserial Serial Peripheral Interface (DSPI) modules for full-duplex, synchronous, communications with
external devices
⢠QuadSPI serial flash memory controller
â Supports single, dual and quad IO serial flash memory
