EP7312
High-Performance, Low-Power System on Chip
CODEC Interface
The EP7312 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.
Table
6
shows
the
Assignments.

Note:
See
Table 18 on page 11
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.
TheSSI2 Interface has these features:
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
Table 7
shows the SSI2 Interfacepin assignments.
Note:
See
Table 18 on page 11
for information on pin
multiplexes.
Synchronous Serial Interface
The EP7312 Synchronous Serial Interface has these
features:
ADC (SSI) Interface: Master modeonly; SPI and
Microwire1-compatible(128 kbps operation)
Selectableserial clock polarity
Table 8
shows the Synchronous Serial Interface pin
assignments.
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. The LCD controller has these
features:
Interfaces directly toa single-scan panel monochrome
STN LCD
Interfaces to a single-scan panel color STN LCD with
minimal external gluelogic
Panel width sizeis programmablefrom 32 to 1024
pixels in 16-pixel increments
Video frame buffer sizeprogrammableup to
128 KB
Bits per pixel of 1, 2, or 4 bits
