to an SPI EEPROM for boot, the designer can choose to
connect the SPI_CS pin to the EEPROM or use a GPIO
(high at boot) for a design with several daisy−chained
SPI devices.
• PCM interface for high−bandwidth digital audio I/O.
This interface comes with configurable input and output
buffers for reduced interrupt handling overhead when
BELASIGNA 250 is used in an audio streaming
application.
• Configurable high−speed RS−232 universal
asynchronous receiver/transmitter (UART).
• RS−232−based communications port for debugging and
in−circuit emulation. This interface can also be used to
send analog audio data to the input stage.
• Two−wire synchronous serial (TWSS) interface
compatible with the I

C protocol and with speeds up to
100 kbps at 1.28 MHz MCLK and up to 400 kbps at
MCLKs higher than 1.92 MHz. Supports master and
slave operation.
Assembly Information
Carrier Details
7 x 7 mm LFBGA
ON Semiconductor offers tape and reel packing for
BELASIGNA 250 LFBGA packages. The packing consists
of a pocketed carrier tape, a cover tape, and a molded
anti−static polystyrene reel. The carrier and cover tape
create an ESD safe environment, protecting the components
from physical and electrostatic damage during shipping and
handling.
