The TX53 is a member of a module series, specially designed for Freescales High-Speed communication interfaces incl. onboard Ethernet PHY / on-chip
i.MX multimedia processors. TX modules are complete computers,
USB PHY allows direct use of connectors/magnetics on the baseboard without
implemented on a board smaller than a credit card, and ready to be designed the need for additional logic:
into your embedded system. TX modules includes a Freescale® i.MX
processor, SDRAM and Flash memory. The integrated LCD-controller enables
•
10/100 Mbps Ethernet
direct connection of an LCD screen. The TX53 is specifically targeted at
•
480 Mbps USB OTG (Host or Device)
embedded applications where size, high cpu-performance and cost are critical
•
480 Mbps USB Host
factors.
Additional interfaces like CAN, 2 UARTs and external memory interface are
Computer on module
available on TX53 specific pins. Some interfaces are multiplexed with other
functions.
