... All Existing ATSAM97xx and ATSAMA2xxx Tools Available for Sound and Soundbank Development 1. Description The ATSAM2553 integrates into a single chip a SAM core (64-slots DSP + 16-bit pro- cessor), a 32K x 16 RAM, an LCD display interface and a scanner allowing direct connection to velocity sensitive keyboards, switches, LEDs and sliders. With addition ...

... The ATSAM2553 can handle directly up to 176 switches. Switches, organized in matrix form, require only a serial diode LEDs can be directly controlled by the ATSAM2553 in a time multiplexed way. Additional LEDs can be connected through additional external shift regis- ters using the GPIO lines (general purpose I/O) of the ATSAM2553 ...

... 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: • ...

... PDWN/ Clock & PLL The highly integrated architecture of the ATSAM2553 combines a specialized high-performance RISC-based digital signal processor (DSP) and a general purpose 16-bit CISC-based control processor (P16). An on-chip memory management unit (MMU) allows the DSP and the control processor to share an internal 32K x 16 RAM as well as external ROM and/or RAM memory devices ...

... ROM device to serve as sample memory storage for the DSP and as program storage for the P16 control processor. An internal 32K x 16 RAM is also connected to the MMU, allowing RAM resources to be shared between the DSP for delay lines and the P16 for program data. 6399A–DRMSD–13-Oct-08 ATSAM2553 5 ...
