Diva Texas Instruments AM335x CPU module[edit | edit source]

DIVA is a CPU module based on Texas Instruments "Sitara" AM335x Cortex-A8 application processor. It is built with SO-DIMM 204 pin form factor and it offers lots of graphics, processing, peripherals and industrial interface options, allowing customer to implement cost-effective designs. The Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) adds further flexibility and enables additional peripherals interfaces and real-time protocols such us EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink.

Main Features[edit | edit source]
