DFLPT
Default
first-level page
table
System control
The DFLPT provides a unique method of implementing the ARM MMU
first-level page table (L1PT) using a hardware-based approach.
DIGCTL
Digital control
and on-chip
RAM
System control
The digital control module includes sections for controlling the SRAM, the
performance monitors, high-entropy pseudo-random number seed,
free-running microseconds counter, and other chip control functions.
DUART
Debug UART
Connectivity
peripherals
The Debug UART performs the following data conversions:
Serial-to-parallel conversion on data received from a peripheral device
Parallel-to-serial conversion on data transmitted to the peripheral device
EMI
External
memory
interface
Connectivity
peripherals
The i.MX28 supports off-chip DRAM storage through the EMI controller,
which is connected to the four internal AHB/AXI busses. The EMI supports
multiple external memory types, including:
1.8-V Mobile DDR1 (LP-DDR1)
Standard 1.8-V DDR2
Low Voltage 1.5-V DDR2 (LV-DDR2)
ENET
Ethernet MAC
Controller
Connectivity
peripherals
Ethernet MAC controller connected to the uDMA (unified DMA). Supports
10/100 Mbps with TCP/UDP/IP Acceleration and IEEE 1588 Functions; also
supports RMII or MII connectivity.
FlexCAN(2)
Controller
area network
module
Connectivity
peripherals
The Controller Area Network (CAN) protocol is a message based protocol
used for serial data. It was designed specifically for automotive but is also
used in industrial control and medical applications. The serial data bus runs
at 1 Mbps.
GPMI
General-pur-
pose media
interface
Connectivity
peripherals
The General-Purpose Media Interface (GPMI) controller is a flexible NAND
flash controller with 8-bit data width, up to 50-MBps I/O speed and individual
chip select and DMA channels for up to 8 NAND devices. It also provides a
interface to 20-bit BCH for ECC.
HSADC
High-speed
ADC
Connectivity
peripherals
The high-speed ADC block is designed to sample an analog input with 12-bit
resolution and a sample rate of up to 2 Msps. The output of the HSADC block
can be moved to the external memory through APBH-DMA. A typical user
case of the HSADC is to work with the PWM block to drive an external linear
image scanner sensor.
I2C(2)
I2C module
Connectivity
peripherals
The I2C is a standard two-wire serial interface used to connect the chip with
peripherals or host controllers. The I2C operates up to 400 kbps in either I2C
master or I2C slave mode. Each I2C has a dedicated DMA channel and can
also controlled by CPU in PIO or PIO queue modes. It supports both 7-bit and
10-bit device address in master mode, and has programmable 7-bit address
in slave mode.
ICOLL
Interrupt
Collector
System control
The ARM9 CPU core has two interrupt input lines, IRQ and FIQ. The interrupt
collector (ICOLL) can steer any of 128 interrupt sources to either the FIQ or
IRQ line of the ARM9 CPU.
L2 Switch
3-Port L2
