The AT8xC51SND1C implement a full-speed USB Interface. It can be used for the fol-
lowing purposes:
•
•
The AT8xC51SND1C implement a MultiMedia Card (MMC) interface compliant to the
V2.2 specification in MultiMedia Card mode. The MMC allows storage of MP3 encoded
audio files in removable Flash memory cards that can be easily plugged to, or removed
from the application. It can also be used for In-System Programming.
The AT8xC51SND1C provide an IDE/ATAPI interface allowing connection of devices
such as CD-ROM reader, CompactFlash
16-bit bi-directional bus part of the low-level ANSI ATA/ATAPI specification. It is pro-
vided for mass storage interfaces but could be used for In-System Programming using
CD-ROM.
The AT8xC51SND1C implement a serial port with its own baud rate generator providing
one single synchronous communication mode and three full-duplex Universal Asynchro-
nous Receiver Transmitter (UART) communication modes. It is provided for the
following purposes:
•
•
The AT8xC51SND1C implement a Serial Peripheral Interface (SPI) supporting master
and slave modes. It is provided for the following purposes:
•
•
•
The AT8xC51SND1C implements a TWI controller supporting the four standard master
and slave modes with multimaster capability. It is provided for the following purposes:
•
•
•
The AT8xC51SND1C implements a 2-channel 10-bit (8 true bits) analog-to-digital con-
verter (ADC). It is provided for the following purposes:
•
•
•
The AT8xC51SND1C implement a keyboard interface allowing connection of 4 x n
matrix keyboard. It is based on 4 inputs with programmable interrupt capability on both
high or low level. These inputs are available as an alternate function of P1.3:0 and allow
exit from idle and power-down modes.
