TX modules are complete computers, implemented on a board smaller than a
credit card, and ready to be designed into your embedded system.
High-Speed communication interfaces incl. onboard Ethernet PHY / on-chip
USB PHY allows direct use of connectors/magnetics on the baseboard without
The TX-48 is pin compatible with all TX modules. This approach has the
the need for additional logic:
advantage of providing the developer with the potential for creating scalable
systems. All modules can be supplied with the same hardware reference

Sitara™ AM335x Processor for Industrial Applications
The AM335x processors based on the ARM® Cortex™-A8 are enhanced with
image, graphics processing, peripherals and industrial interface options such
as EtherCAT.
AM335x processors are broad market application processors with image,
graphics processing, and peripherals.
Power Supply
The TX48 accepts an input voltage from various sources:
•
•
•
1-cell Li-Ion/Polymer (3.1V to 4.2V)
5.0V USB supply or AC wall adapter
3.3V
Read more in our TX-Guide:
www.karo-electronics.com/TX-Guide
The AM335x processor contains these
subsections:
• Microprocessor unit (MPU) subsystem based
on the ARM® Cortex™-A8 processor
• POWERVR® SGX Graphics Accelerator
Subsystem for 3D graphics acceleration to
support display and gaming effects.
• Programmable Real-time Unit (PRU) subsystem enables the user to create a variety of
digital resources beyond native peripherals of
the device. In addition, the PRU is separate
from the ARM core. This allows independent
operation and clocking to give the device
greater flexibility in complex system solutions.
• High performance interconnects provide highbandwidth data transfers for multiple initiators
to the internal and external memory controllers
and to on-chip peripherals. The device also
offers a comprehensive clock-management
scheme.
• The on-chip analog to digital converter (ADC)
can be coupled with the LCD controller to
provide an integrated touch screen solution. In
addition, the ADC can be used in combination
with the pulse width module to create a closed
loop motor control solution.
