Key Document


TI provides the system solution for Industrial Communication on Sitara™ processors with Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS). PRU-ICSS allows custom firmware applications in the field of real-time applications. The I2C peripheral on many application processors does not support SMbus commands like block read and block write transfers. The TIDEP0065 TI Design implements those SMbus commands with standard I2C commands into the PRU-ICSS peripheral.

  • Supports I2C and SMbus master interface with PRU-ICSS
  • Dynamic block moe read and write transfer
  • Contains PRU-ICSS source code for customization
  • I2C register interface emulation
