Description
The ATSAM9753 integrates into a single chip an ATSAM97xx core (64-slot DSP and
16-bit processor), a 32K x 16 RAM, an LCD display interface and a scanner, allowing
direct connection to velocity-sensitive keyboards, switches, LEDs and sliders. With the
addition of a single external ROM or Flash and a stereo DAC, a complete low-cost
musical instrument can be built that includes reverb and chorus effects, parametric
equalizer, surround effects, orchestrations, pitch-bend and wheel controller, without
compromising on sound quality. The ATSAM9753 is packaged in a standard 144-lead
TQFP package.

Table 1. Pin Description by Function (Continued)
Pin Name
Pin Number
Type Function
BR[10:0]
1 - 3, 135 - 138, 141 - 144 IN
Keyboard contact 1/switch status. When KBDIO = 1 then BR[10:0] holds the
keyboard key-off or first contact status. This can be configured as normally
closed (spring type), normally open (rubber type), common anode or
common cathode contact diodes. When KBDIO = 0 then BR[10:0] holds the
switch status from ROW[2:0] or ROW[3:0].
MK[10:0]
120 - 124,127, 128,
131 - 134
I/O Keyboard contact 2/LED data. When KBDIO =1 then MK[10:0] holds the
keyboard key-on or second contact status. This can be configured as
common anode or common cathode contact diodes.When KBDIO = 1 then
MK[10:0] holds the led data from ROW[2:0].
VREFP

ANA
ANA
Positive reference voltage. Should normally be connected to a clean AVC3
supply.
Negative reference voltage. Should normally be connected to a clean AGND.
VIN 104
ANA
Slider analog input. Ranges from VREFN to VREFP. Should hold the
ROW[2:0] or ROW[3:0] slider voltage. Multiple sliders should be connected
through external analog multiplexer(s) like 4051.
LCD Display Interface(2)

OUT Select instruction (LOW) or data (HIGH).
RW 15
OUT Select write (LOW) or read (HIGH).
ENB

OUT Enable, active high.
DB[7:0]

I/O Bi-directional data bus.
Digital Audio Group(3)
DACLK
93
OUT Master clock for sigma-delta DAC (256 x Fs).
DABD[1:0]
89, 92
OUT Serial data for two stereo output channels.
DAAD
88
IN Serial data for one stereo input channel.
CLBD
86
OUT Digital audio bit clock.
WSBD
87
OUT Digital audio left/right select.
Miscellaneous Pins
GPIO[4:0]
108, 109, 112 - 114
I/O These pins can be used individually as general-purpose I/Os or as alternate
functions. When used as general-purpose I/Os, they can be individually
configured as inputs or outputs. When used as alternate functions their
meaning changes as follows:
GPIO0 = ROW3 expands switches to 176, sliders to 16
GPIO2 = DBCLK (input)
GPIO3 = DBACK (output)
GPIO4 = DBDATA (I/O) (DBDATA input = DBIN, DBDATA output = DBOUT)
DBCLK, DBACK, DBDATA are used for debugging or external Flash memory
programming when DEBUG is low
DEBUG
RESET
85
83
IN Configuration pin, low for CodeView debugging/external Flash memory
programming. Should be tied to VCC for normal operation.
IN Reset input, active low. This is a Schmitt trigger input, allowing direct
connection of a RC network.
RUN
118
OUT Indicates that the DSP is up and running. Can be used as external DAC
reset.
