It is also be based on Cortex - A8 development platform,but more stable and cost less. So that, you can be familiar with TI AM335X processor's characteristics and design method quickly, and speed up your product development progress. The Characteristics of TI Sitara AM335X: The MPU is based on ARM Cortex-A8 development platform, the MAX of frequency is 720MHz. Support LPDDR1/DDR2/DDR3. The selection of Power Managerment s chip is agile.for example, TI TPS65910,TPS65217 and so on. Have the function of UI and 3D,and be integrated graphics accelerator and display controller. Integrated Dual Gigabit Ethernet interface,and up to 6-channel UART serial port, 2-channel CAN transceiver. Agile peripheral integration provides up to 4 groups GPIO port and each group 32pcs, part of the port can be realized up to seven reuse functions. Integrated programmable real-time unit (PRU) on chip which is unique for TI. Moreover,it provides configurable I/O configuration and the function of expand peripherals agilely. TQ_AM335X Development Board is composed of Core Board and Base Board.This two parts use U size double contact pin interface to connect each other and lead to all available interface of AM335X. 2
