ATSAM2553

RAM is enough to handle firmware variables and reverb delay lines. External flash memory can

be programmed on-board from a host processor through the ATSAM2553.

The ATSAM2553 operates from a single 12.2880 MHz crystal. A built-in PLL raises the fre-

quency to 49.152 MHz for internal processing. This allows to minimize radio frequency

interference (RFI), making it easier to comply with FCC, CSA, CE standards.

A power-down feature is also included which can be controlled externally (PDWN pin). This

makes the ATSAM2553 very suitable for battery operated instruments.

The ATSAM2553 has been designed with final instrument quick time to market in mind. The

ATSAM2553 product development program includes key features to minimize product develop-

ment efforts:

• C compiler for built-in P16 processor

• Specialized debug interface, allowing on-target software development with a source code

debugger.

• Standard sound generation/processing firmware

• Standard orchestration firmware

• Windows tools for sounds, soundbanks and orchestrations developments

• Standard soundbanks
