EP7311
High-Performance, Low-Power System on Chip
CODEC Interface
The EP7311 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 theMCP and
SSI2.
Note:
See
Table R on page 8
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
theMCP 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 R on page 8
for information on pin
multiplexes.
Synchronous Serial Interface
ADC (SSI) Interface: Master modeonly; SPI and
Microwire1-compatible(128 kbps operation)
Selectableserial clock polarity
LCD Controller
A DMA address generator is provided that fetches video
display data for the LCD controller from memory. The
display frame buffer start address is programmable,
allowing the LCD frame buffer to be in SDRAM, internal
SRAM or external SRAM.
