EP7309
High-Performance, Low-Power System on Chip
Universal Asynchronous
Receiver/Transmitters (UARTs)
The EP7309 includes two 16550-type UARTs for RS-232
serial communications, both of which have two 16-byte
FIFOs for receiving and transmitting data. The UARTs
support bit rates up to 115.2 kbps. An IrDA SIR protocol
encoder/decoder can be optionally switched into the
RX/TX signals to/from UART 1 to enable these signals
to drive an infrared communication interface directly.
Digital Audio Interface (DAI)
The EP7309 integrates an interface to enable a direct
connection to many low cost, low power, high quality
audio converters. In particular, the DAI can directly
interface with the Crystal
CS43L41/42/43 low-power
audio DACs and the Crystal
CS53L32 low-power ADC.
Some of these devices feature digital bass and treble
boost, digital volume control and compressor-limiter
functions.
Note:
See
Table Q on page 7
for information on pin
multiplexes.
CODEC Interface
The EP7309 includes an interface to telephony-type
CODECs for easy integration into voice-over-IP and
other voice communications systems. The CODEC
interface is multiplexed to the same pins as the DAI and
SSI2.
Note:
See
Table Q on page 7
for information on pin
multiplexes.
SSI2 Interface
An additional SPI/Microwire1-compatible interface is
available
for
both
master
communications. The SSI2 unit shares the same pins as
the DAI and CODEC interfaces through a multiplexer.
and
slave
mode
Synchronous clock speeds of up to 512 kHz
Separate 16 entry TX and RX half-word wide FIFOs
Half empty/full interrupts for FIFOs
Separate RX and TX frame sync signals for
asymmetric traffic
Note:
See
Table Q on page 7
for information on pin
multiplexes.
