TX modules are complete Keypad 4x4 computers, implemented on a board smaller than a credit card, and ready to CSPI (Configurable serial peripheral interface) be designed into your embedded system. TX modules includes a NXP i.MX 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. 10/100 Mbps Ethernet Computer on module 480 Mbps USB OTG 12 Mbps USB Host NXP i.MX257, 400 MHz 64 MByte SDRAM (16bit) Additional interfaces like CAN, 4/5-wire resistive touch-screen, 2 UARTs and 128 MByte NAND Flash memory external memory interface are available on TX25 specific pins. Some DIMM200-module (67,6mm x 26 mm x 3,6mm) interfaces are multiplexed with other functions. Operating temperature range -40..85C 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 1-cell Li-Ion/Polymer (3.1V to 4.2V) support, three general-purpose 12-bit ADCs, a touch screen controller and 5.0V USB supply or AC wall adapter integrated 128K SRAM to improve system performance or low-power LCD 3.3V refresh.
