  • Page 18 The 56F826EVM uses a Freescale DSP56F826BU80 part, designated as U1 on the board and in the schematics. This part will operate at a maximum speed of 80MHz. A full description of the 56F826, including functionality and user information, is provided in these documents: • 56F826 Preliminary Technical Data Sheet, (DSP56F826-827 UM): Provides features list and specifications including signal descriptions, DC power requirements, AC timing requirements and available packaging.

  • Page 19: Program And Data Memory

    This memory bank will operate with zero wait state accesses while the 56F826 is running at 70MHz. However, when running at 80MHz, the memory bank operates with four wait state accesses. This memory bank can be disabled by removing the jumper at JG3.

  • Page 20: Spi Eeprom Memory

    2-2. This memory connects directly to the SPI Port through a Figure header on the 56F826. It can be used to load program code and data into the 56F826’s internal or external memory spaces. A jumper block, JG7, is provided, which allows the user to disconnect the on-board SPI EEPROM from the SPI port and to connect his own SPI port peripheral.
