i.MX28 Features and Functionality
The ConnectCard for i.MX28 mod
ule is based on the i.MX28 proc
essor series from Freescale.
This processor offers a high number of interf
aces. Most of these interfaces are multiplexed
and are not available simultaneously. Not all feat
ures are available on all variations of the
module. More in-depth information can be
found in the “i.MX28 Application Processor
Reference Manual” on the Freescale web site.
The i.MX28 processor uses an ARM 926 core
with on-chip RISC (Reduced
Instruction Set Computer).
The ConnectCard for i.MX28 module has the following i.MX28 features:
LRADC (Low Resolution ADC)
HSADC (High Speed ADC)
GPIO (General Purpose Input Output)
SD/SDIO/MMC (Secure Digital/ Secure Di
gital Input Output/ Multi-Media Card)
UART (Universal Asynchronous Receiver/Transmitter)
DUART (Debug Universal Asynchronous Receiver/Transmitter)
SPI (Serial Peripheral Interface)
I2C (Inter-Integrated Circuit)
CAN (Controller Area Network)
USB OTG (Universal Serial Bus On-the-Go)
USB Host (Universal Serial Bus)
ENET (Ethernet)
SAIF (Serial Audio Interface)
PWM (Pulse Width Modulator)
LCD (Liquid Crystal Display)
ETM (Embedded Trace Macrocell)
JTAG (Joint Test Action Group)
802.11 abgn and Bluetooth
Flash Memory
DDR2 Memory
One-Wire Interface
Power supply options - Battery and DC
ccardwmx28js (wireless version of same module) already has wifi chip (Atheros wireless chip) interfaced on SSP2 interface. Hope this is useful info…
