Notes:
Description
The highly integrated architecture of the ATSAM9713 combines a specialized high-
performance RISC digital signal processor and a general-purpose 16-bit CISC control
processor on a single chip. An on-chip memory management unit allows the digital
signal processor and the control processor to share external ROM and RAM devices.
The ROM bus width should be 16 bits while the SRAM can be selected to be 8 or 16
bits wide. When using an 8-bit SRAM, fast type (static cache) should be selected
because two SRAM cycles will be completed in one ROM cycle duration.
Running at 300 million operations per second (MOPS), the digital signal processor
supports high-quality PCM synthesis as well as most important functions like reverb,
chorus, surround effect and equalizer. By adding an additional stereo DAC, four-chan-
nel audio surround can also be obtained.
The ATSAM9713 operates from a low-frequency 9.6 MHz typical crystal. A built-in PLL
raises this frequency to a 38.4 MHz internal clock that controls the two processors.
Care has been taken that output pin signals change only when necessary. This mini-
mizes RFI (radio frequency interferences) and power consumption. Minimizing RFI is
mostly important in order to comply with standards such as FCC, CSA and CE.
The core power supply for the ATSAM9713 should range from 3V to 4.5V; the periph-
ery supports supply from 3V to 5.5V. Therefore, by selecting 3.3V ROM, SRAM and
DAC, it is possible to develop low-power/low-voltage portable applications.
