Slave Address Byte
Following a START condition, the master must output
a Slave Address Byte (Refer to figure 13.). This byte
includes three parts:
– The four MSBs (SA7 - SA4) are the Device Type
Identifier, which must always be set to 1010 in order
to select the X96011.
– The next three bits (SA3 - SA1) are the Device
Address bits (AS2 - AS0). To access any part of the
X96011’s memory, the value of bits AS2, AS1, and
AS0 must correspond to the logic levels at pins A2,
A1, and A0 respectively.
– The LSB (SA0) is the R/W bit. This bit defines the
operation to be performed on the device being
addressed. When the R/W bit is “1”, then a Read
operation is selected. A “0” selects a Write
operation (Refer to figure 13.)
Nonvolatile Write Acknowledge Polling
After a nonvolatile write command sequence is cor-
rectly issued (including the final STOP condition), the
X96011 initiates an internal high voltage write cycle.
This cycle typically requires 5 ms. During this time,
any Read or Write command is ignored by the
X96011. Write Acknowledge Polling is used to deter-
mine whether a high voltage write cycle is completed.
During acknowledge polling, the master first issues a
START condition followed by a Slave Address Byte.
The Slave Address Byte contains the X96011’s Device
Type Identifier and Device Address. The LSB of the
Slave Address (R/W) can be set to either 1 or 0 in this
case. If the device is busy within the high voltage
cycle, then no ACK is returned. If the high voltage
cycle is completed, an ACK is returned and the master
can then proceed with a new Read or Write operation.
(Refer to figure 14.).
Byte Write Operation
In order to perform a Byte Write operation to the mem-
ory array, the Write Enable Latch (WEL) bit of the Con-
trol 6 Register must first be set to “1”. (See “WEL:
Write Enable Latch (Volatile)” on page 13.)
For any Byte Write operation, the X96011 requires the
Slave Address Byte, an Address Byte, and a Data Byte
(See Figure 15). After each of them, the X96011
responds with an ACK. The master then terminates the
transfer by generating a STOP condition. At this time, if
all data bits are volatile, the X96011 is ready for the next
read or write operation. If some bits are nonvolatile, the
X96011 begins the internal write cycle to the nonvolatile
memory. During the internal nonvolatile write cycle, the
X96011 does not respond to any requests from the
master. The SDA output is at high impedance.
Writing to Control bytes which are located at byte
addresses 80h through 8Fh is a special case
described in the section “Writing to Control Registers” .
Page Write Operation
The 80-byte memory array is physically realized as
one contiguous array, organized as 5 pages of 16
bytes each. A “Page Write” operation can be per-
formed to any of the four LUT pages. In order to per-
form a Page Write operation, the Write Enable Latch
(WEL) bit in Control register 6 must first be set (See
“WEL: Write Enable Latch (Volatile)” on page 13.)
A Page Write operation is initiated in the same manner
as the byte write operation; but instead of terminating
the write cycle after the first data byte is transferred,
the master can transmit up to 16 bytes (See Figure
16). After the receipt of each byte, the X96011
responds with an ACK, and the internal byte address
counter is incremented by one. The page address
remains constant. When the counter reaches the end
of the page, it “rolls over” and goes back to the first
byte of the same page.
