Brief Description
1-Wire support provided for interfacing with an on-board EEPROM, and smart
battery interfaces, for example: Dallas DS2502.
The ARM Cortex™-A8 Core Platform consists of the ARM Cortex™-A8
processor version r2p5 (with TrustZone) and its essential sub-blocks. It contains
the Level 2 Cache Controller, 32 Kbyte L1 instruction cache, 32 Kbyte L1 data
cache, and a 256 Kbyte L2 cache. The platform also contains an Event Monitor
and Debug modules. It also has a NEON co-processor with SIMD media
processing architecture, register file with 32
×
64-bit general-purpose registers,
an Integer execute pipeline (ALU, Shift, MAC), dual, single-precision floating
point execute pipeline (FADD, FMUL), load/store and permute pipeline and a
Non-Pipelined Vector Floating Point (VFP) co-processor (VFPv3).
The elements of the audio subsystem are three Synchronous Serial Interfaces
(SSI1-3), a Digital Audio Mux (AUDMUX), and Digital Audio Out (SPDIF TX).
See the specific interface listings in this table.
The AUDMUX is a programmable interconnect for voice, audio, and
synchronous data routing between host serial interfaces (for example, SSI1,
SSI2, and SSI3) and peripheral serial interfaces (audio and voice codecs). The
AUDMUX has seven ports (three internal and four external) with identical
functionality and programming models. A desired connectivity is achieved by
configuring two or more AUDMUX ports.

Full-duplex enhanced Synchronous Serial Interface, with data rate up to
66.5 Mbit/s (for eCSPI, master mode). It is configurable to support Master/Slave
modes, four chip selects to support multiple peripherals.
The Central Security Unit (CSU) is responsible for setting comprehensive
security policy within the i.MX51 platform, and for sharing security information
between the various security modules. The Security Control Registers (SCR) of
the CSU are set during boot time by the High Assurance Boot (HAB) code and
are locked to prevent further writing.
The Debug System provides real-time trace debug capability of both instructions
and data. It supports a trace protocol that is an integral part of the ARM Real
Time Debug solution (RealView). Real-time tracing is controlled by specifying a
set of triggering and filtering resources, which include address and data
comparators, cross-system triggers, counters, and sequencers.

EMI

Brief Description
The EMI is an external and internal memory interface. It performs arbitration
between multi-AXI masters to multi-memory controllers, divided into four major
channels: fast memories (Mobile DDR, DDR2) channel, slow memories
(NOR-FLASH/PSRAM/NAND-FLASH and so on) channel, internal memory
(RAM, ROM) channel and graphical memory (GMEM) Channel.
In order to increase the bandwidth performance, the EMI separates the buffering
and the arbitration between different channels so parallel accesses can occur.
By separating the channels, slow accesses do not interfere with fast accesses.
EMI features:
• 64-bit and 32-bit AXI ports
• Enhanced arbitration scheme for fast channel, including dynamic master
priority, and taking into account which pages are open or closed and what
type (Read or Write) was the last access
• Flexible bank interleaving
• Supports 16/32-bit Mobile DDR up to 200 MHz SDCLK (mDDR400)
• Supports 16/32-bit (Non-Mobile) DDR2 up to 200 MHz SDCLK (DDR2-400)
• Supports up to 2 Gbit Mobile DDR memories
• Supports 16-bit (in muxed mode only) PSRAM memories (sync and async
operating modes), at slow frequency, for debugging purposes
• Supports 32-bit NOR-Flash memories (only in muxed mode), at slow
frequencies for debugging purposes
• Supports 4/8-ECC, page sizes of 512 Bytes, 2 Kbytes and 4 Kbytes
• NAND-Flash (including MLC)
• Multiple chip selects
• Enhanced Mobile DDR memory controller, supporting access latency hiding
• Supports watermarking for security (Internal and external memories)
• Supports Samsung OneNAND
™
(only in muxed I/O mode)
Each EPIT is a 32-bit “set and forget” timer that starts counting after the EPIT is
enabled by software. It is capable of providing precise interrupts at regular
intervals with minimal processor intervention. It has a 12-bit prescaler for division
of input clock frequency to get the required time setting for the interrupts to occur,
and counter values can be programmed on the fly.
The features of the eSDHC module, when serving as host, include the following:
• Conforms to SD Host Controller Standard Specification version 2.0
• Compatible with the MMC System Specification version 4.2
• Compatible with the SD Memory Card Specification version 2.0
• Compatible with the SDIO Card Specification version 1.2
• Designed to work with SD Memory, miniSD Memory, SDIO, miniSDIO, SD
Combo, MMC and MMC RS cards
• Configurable to work in one of the following modes:
—SD/SDIO 1-bit, 4-bit
—MMC 1-bit, 4-bit, 8-bit
• Full-/high-speed mode
• Host clock frequency variable between 32 kHz to 52 MHz
• Up to 200 Mbps data transfer for SD/SDIO cards using four parallel data lines
• Up to 416 Mbps data transfer for MMC cards using eight parallel data lines
