TDA7500A
PIN DESCRIPTION
N° Name Type Description
1 GND1 Ground pin dedicated to the digital circuitry.
2 VDD1 Supply pin dedicated to the digital circuitry.
3 TESTEN I Test Enable (Input). When low, puts the chip into test mode and
muxes the XTI clock to all flip-flops. When TEST_SE is also
active, the scan chain shifting is enabled. To be connected to
Vdd in operating mode.
4 TESTSE I SCAN Enable (Input). When high with TESTEN also active,
controls the shifting of the internal scan chains. When active with
TESTEN not active, sets all tri-state outputs into hi-impedance
mode. To be connected to GND in operating mode.
5 NRESET I System Reset (Input). A low level applied to NRESET input
initializes the IC.
6 SCKM/DSP0_GPIO0 I/O
I
2
C Serial Clock Line (Input/Output)/SPI Bit Clock (Input)/
General Purpose I/O (Input/Output). Clock line for I
2
C bus. If SPI
interface is enabled, behaves as SPI bit clock. Optionally it can
be used as general purpose I/O controlled by DSP0.
7 MISOM/DSP0_GPIO1 I/O
I
2
C Serial Data Line (Input/Output)/SPI Master Input Slave
Output Serial Data (Input/Output)/General Purpose I/O (Input/
Output). Data line for I
2
C bus. If SPI is enabled, behaves as
Serial Data Input when in SPI Master Mode and Serial Data
Output when in SPI Slave Mode. Optionally it can be used as
general purpose I/O controlled by DSP0.
8 MOSIM/DSP0_GPIO2 I/O SPI Master Output Slave Input Serial Data (Input/Output)/
General Purpose I/O (Input/Output). Serial Data Output when in
SPI Master Mode and Serial Data Input when in SPI Slave
Mode. Optionally it can be used as general purpose I/O
controlled by DSP0.
9 SSM/DSP0_GPIO3 I SPI Slave Select (Input)/General Purpose I/O (Input/Output). If
SPI is enabled, behaves as Slave Select line for SPI bus.
Optionally it can be used as general purpose I/O controlled by
DSP0.
10 SCKD/DSP0_GPIO4 I SPI Bit Clock (Input)/General Purpose I/O (Input/Output). SPI bit
clock. Optionally it can be used as general purpose I/O
controlled by DSP0.
11 MISOD/DSP0_GPIO5 I/O SPI Master Input Slave Output Serial Data (Input/Output)/
General Purpose I/O (Input/Output). Behaves as Serial Data
Input when in SPI Master Mode and Serial Data Output when in
SPI Slave Mode. Optionally it can be used as general purpose I/
O controlled by DSP0.
12 MISOD/DSP0_GPIO6 I/O SPI Master Output Slave Input Serial Data (Input/Output)/
General Purpose I/O (Input/Output). Serial Data Output when in
SPI Master Mode and Serial Data Input when in SPI Slave
Mode. Optionally it can be used as general purpose I/O
controlled by DSP0.
13 SSD/DSP0_GPIO7 I SPI Slave Select (Input)/General Purpose I/O (Input/Output).
Behaves as Slave Select line for SPI bus. Optionally it can be
used as general purpose I/O controlled by DSP0.
