DESCRIPTION
Using Catalyst's advanced CMOS technology which
substantially reduces device power requirements, the
CAT24C208 can be powered from either of two
independent VCC inputs.
The CAT24C208 is an 8k-bit Dual Port Serial CMOS
EEPROM internally organized as 1k words of 8 bits
each. The CAT24C208 features a 16-byte page write
buffer and can be accessed from either of two separate
I2C compatible ports, DSP (SDA, SCL) and DDC (SDA,
SCL) which conform to the VESA E-EDID EEPROM
Standard.
The CAT24C208 operates over the full industrial and
extended temperature range and is available in
miniature 8-pin DIP, SOIC, TSSOP and MSOP
packages.
Arbitration between the two interface ports is automatic
and allows the appearance of individual access to the
memory from each interface.

interface, the memory space appears as two 500 byte
banks of memory, with 2 segments each 00h and 01h in
the upper and lower bank, see Table 1.
FUNCTIONAL DESCRIPTION
The CAT24C208 has a total memory space of 1K bytes
which is accessible from either of two I2C interface
ports, (DSP_SDA and DSP_SCL) or (DDC_SDA and
DDC_SCL), and with the use of segment pointer at
address 60h. On power up and after any instruction, the
segment pointer will be in segment 00h for DSP and in
segment 00h of the bank selected by the configuration
register for DDC.
Each bank of memory can be used to store an E-EDID
data structure. However, only one bank can be read
through the DDC port at a time. The active bank of
memory (that is, the bank that appears at address A0h
on the DDC port) is controlled through the configuration
register at 62/63h and the EDID_SEL pin.
NowriteoperationsarepossiblefromtheDDCinterface
unless the DDC Write Enable bit is set (WE = 1) in the
device configuration register at device address 62h.
The entire memory appears as contiguous memory
space from the perspective of the display interface
(DSP_SDA and DSP_SCL), see Table 2, and Figures
11 to Figure 18 for a complete description of the DSP
Interface.
The device automatically arbitrates between the two
interfaces to allow the appearance of individual access
to the memory from each interface.
A configuration register at addresses 62/63h is used to
configure the operation and memory map of the device
as seen from the DDC interface, (DDC_SDA and
DDC_SCL).
In a typical E-EDID application the EDID_SEL pin is
usually connected to the “Analog Cable Detect” pin of a
VESA M1 compliant, dual-mode (analog and digital)
display. In this manner, the E-EDID appearing at ad-
dress A0h on the DDC port will be either the analog or
digital E-EDID, depending on the state of the “Analog
Cable Detect” pin (pin C3 of the M1-DA connector). See
Figure 1.
Read and write operations can be performed on any
location within the memory space from the display DSP
interface regardless of the state of the EDID SEL pin or
the activity on the DDC interface. From the DDC

I2C Bus Protocol
Acknowledge
ThefollowingdefinesthefeaturesoftheI2Cbusprotocol:
After a successful data transfer, each receiving device is
requiredtogenerateanacknowledge.Theacknowledging
devicepullsdowntherespectiveSDAlineduringtheninth
clock cycle, signaling that it received the 8 bits of data.
(1) Data transfer may be initiated only when the bus is
not busy.
(2) During a data transfer, the data line must remain
stable whenever the clock line is high. Any changes
in the data line while the clock line is high will be
interpreted as a START or STOP condition.
The CAT24C208 responds with an acknowledge after
receiving a START condition and its slave address. If the
device has been selected along with a write operation, it
responds with an acknowledge after receiving each 8-bit
byte.
START Condition
The START Condition precedes all commands to the
device, and is defined as a HIGH to LOW transition of
either SDA when the respective SCL is HIGH. The
CAT24C208 monitors the SDA and SCL lines and will
not respond until this condition is met.
When the CAT24C208 is in a READ mode it transmits 8
bits of data, releases the respective SDA line, and
monitors the line for an acknowledge. Once it receives
this acknowledge, the CAT24C208 will continue to
transmit data. If no acknowledge is sent by the Master,
the device terminates data transmission and waits for a
STOP condition.
STOP Condition
A LOW to HIGH transition of SDA when SCL is HIGH
determinestheSTOPcondition.Alloperationsmustend
with a STOP condition.
After an unsuccessful data transfer an acknowledge will
not be issued (NACK) by the slave (CAT24C208), and
the master should abort the sequence. If continued the
device will read from or write to the wrong address in the
two instruction format with the segment pointers.

DEVICE ADDRESSING
DDC Interface
Both the DDC and DSP interfaces to the device are based on the I2C bus serial interface. All memory space operations
are done at the A0/A1 DDC address pair. As such, all write operations to the memory space are done at DDC address
A0h and all read operations of the memory space are done at DDC address A1h.
Figure 3 shows the bit sequence of a random read from anywhere within the memory space. The word offset
determines which of the 256 bytes within segment 00h is being read. Here the segment 00h can be at the lower or
upper bank depending on the configuration register.
Sequential reads can be done in much the same manner by reading successive bytes after each acknowledge without
generating a stop condition. See Figure 4. The device automatically increments the word offset value (8-bit value) and
with wraparound in the same segment 00h to read maximum of 256 bytes.

Thesegmentpointerisattheaddress60handiswrite-only. Thismeansthatamemoryaccessat61hwillgiveundefined
results. The segment pointer is a volatile register. The device configuration register at 62/63 (hex) is a non-volatile
register. The configuration register will be shipped in the erased (set to FFh) state.
The segment pointer is used to expand the available DDC address space while maintaining backward compatibility with
older DDC interfaces such as DDC2B. For each value of the 8-bit segment pointer one segment (256 bytes) is available
at the A0/A1 pair. The standard DDC 8-bit address is sufficient to address each of the 256 bytes within a segment. Note
that if the segment pointer is set to 00h then the device will behave like a standard DDC2B EEPROM.
Read and write with segment pointer can expand the addressable memory to 512 bytes in each bank with wraparound
to the next segment in the same bank only. The two banks can be individually selected by the configuration register and
EDID Sel pin, as shown in figure 19. The segments are selected by the two bits S1S0 = 00 or 01 in the segment address.

The DSP interface is similar to I2C bus serial interface. Without the segment pointer, the maximum accessible memory
space is 256 bytes of segment 00h only. In the sequential mode the wrap around will be in the same segment also.

it low, holding off activity on the other port (by stretching
the clock on that port). When the initiating SCL line has
remained high for one full second, the arbitration logic
assumes that the initiating devices is finished and
releases the other SCL line. If the non-initiating device
has been waiting for access, it can now read or write the
device.
ARBITRATION
The device performs a simplistic arbitration between the
DDCanddisplayinterfaces.Whilethearbitrationscheme
described is not foolproof, it does prevent most errors.
The arbitration logic uses “clock stretching”, an I2C bus
term, to hold off writes from one port while the other port
is active.
For this scheme to work properly, both the DDC and
DSP devices must properly implement clock stretching
as defined by the I2C specification. Additionally, it is very
important that when writing to the device that the SCL
line never remains high longer than 1 second, until the
write is complete. This prevents the other port from
having access until the device is fully written.
Arbitration logic within the device monitors activity on
DDC_SCLandDSP_SCL.WhenbothI2Cportsareidle,
DDC_SCL and DSP_SCL are both high and the
arbitration logic is inactive. When either DDC_SCL or
DSP_SCL is pulled low, initiating a read or write, the
arbitration logic pulls down the other SCL line and holds
