SAM2653

Configuration options allow the SAM2653 to cover a wide range of musical products,

from the lowest cost keyboard to the high range digital piano, thanks to flexible memory

and I/O organization: built-in 64k bytes RAM, up to 64M bytes external memory for

firmware, orchestrations and PCM data. The external memory can be ROM, RAM or

FLASH. Memory types can be mixed, but for most applications there is no need for

external RAM memory as the built-in 64k bytes 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 SAM2653.

The SAM2653 operates from a single 12.2880 MHz crystal. A built-in PLL raises the

frequency to 49.152MHz 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 (RST/PD/ pin).

This makes the SAM2653 very suitable for battery operated instruments.

The SAM2653 has been designed with final instrument quick time to market in mind.

The SAM2653 product development program includes key features to minimize product

development 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, sound banks and orchestrations developments

-

Standard sound banks

-

Strong technical support available directly from Dream
