The i.MX 6ULL processors are based on Arm Cortex-A7 MPCore™ Platform, which has the following
features:
• Supports single Arm Cortex-A7 MPCore (with TrustZone) with:
— 32 KB L1 Instruction Cache
— 32 KB L1 Data Cache
— Private Timer and Watchdog
— Cortex-A7 NEON Media Processing Engine (MPE) Co-processor
• General Interrupt Controller (GIC) with 128 interrupts support
• Global Timer
• Snoop Control Unit (SCU)
• 128 KB unified I/D L2 cache
• Single Master AXI bus interface output of L2 cache
• Frequency of the core (including Neon and L1 cache), as per Table 10, “Operating Ranges,” on
page 24.
• NEON MPE coprocessor
— SIMD Media Processing Architecture
— NEON register file with 32×64-bit general-purpose registers
— NEON Integer execute pipeline (ALU, Shift, MAC)
— NEON dual, single-precision floating point execute pipeline (FADD, FMUL)
— NEON load/store and permute pipeline
— 32 double-precision VFPv3 floating point registers
The SoC-level memory system consists of the following additional components:
— Boot ROM, including HAB (96 KB)
— Internal multimedia/shared, fast access RAM (OCRAM, 128 KB)
• External memory interfaces: The i.MX 6ULL processors support latest, high volume, cost effective
handheld DRAM, NOR, and NAND Flash memory standards.
— 16-bit LP-DDR2-800, 16-bit DDR3-800 and DDR3L-800
— 8-bit NAND-Flash, including support for Raw MLC/SLC, 2 KB, 4 KB, and 8 KB page size,
BA-NAND, PBA-NAND, LBA-NAND, OneNAND™ and others. BCH ECC up to 40 bits.
— 16/8-bit NOR Flash. All EIMv2 pins are muxed on other interfaces.
Each i.MX 6ULL processor enables the following interfaces to external devices (some of them are muxed
and not available simultaneously):

— Electrophoretic display controller support direct-driver for E-Ink EPD panel, with up to
2048×1536 resolution at 106 Hz
• Camera sensors:
— One parallel camera port, up to 24 bit and 133.3 MHz pixel clock
— Support 24-bit, 16-bit, 10-bit, and 8-bit input
— Support BT.656 interface
• Expansion cards:
— Two MMC/SD/SDIO card ports all supporting:
– 1-bit or 4-bit transfer mode specifications for SD and SDIO cards up to UHS-I SDR-104
mode (104 MB/s max)
– 1-bit, 4-bit, or 8-bit transfer mode specifications for MMC cards up to 52 MHz in both SDR
and DDR modes (104 MB/s max)
