Description
The ATSAM9743 integrates into a single chip an ATSAM97xx core (64-slot DSP + 16-
bit processor), a 24K x 16 Flash memory, a 2K x 16 RAM, and up to 64 individually
programmable I/O pins. With the addition of a single external digital-to-analog con-
verter or a codec, the ATSAM9743 can be used in a variety of musical and sound
processing applications, like low-cost keyboards, equalizers and effect processors.
I/O pins can be configured for external memory expansion, allowing more sophisti-
cated products with up to 4M bytes RAM or ROM.
