The TX25 is a member of a module series, specially designed for Freescales
i.MX25 multimedia processors. TX modules are complete computers,
implemented on a board smaller than a credit card, and ready to be designed
into your embedded system. TX modules includes a Freescale® i.MX
CSPI (Configurable serial peripheral interface)
processor, SDRAM and Flash memory. The integrated LCD-controller enables High-Speed communication interfaces incl. onboard Ethernet PHY / on-chip
direct connection of an LCD screen. The TX25 is specifically targeted at USB PHY allows direct use of connectors/magnetics on the baseboard without
embedded applications where size, high cpu-performance and cost are critical the need for additional logic:
factors.

Additional interfaces like CAN, 4/5-wire resistive touch-screen, 2 UARTs and
external memory interface are available on TX25 specific pins. Some
interfaces are multiplexed with other functions.
Power Supply
Processor
The TX25 accepts an input voltage from various sources:
The i.MX257 processor introduces several key new features such as 3.3V I/O
support, three general-purpose 12-bit ADCs, a touch screen controller and
integrated 128K SRAM to improve system performance or low-power LCD
refresh.
