DESCRIPTION
The X24F128 is a CMOS SerialFlash Memory, inter-
nally organized 16K x 8. The device features a serial
interface and software protocol allowing operation on a
simple two wire bus.
Three device select inputs (S0–S2) allow up to eight
devices to share a common two wire bus.
A Program Protect Register at the address location
FFFFh provides three program protection features:
Software Program Protect, Block Lock Protect, and
Hardware Program Protect. The Software Program
Protect feature prevents any nonvolatile writes to the
device until the PEL bit in the Program Protect
Register is set. The Block Lock Protection feature
allows the user to individually block protect four blocks
of the array by programming two bits in the Program
Protect Register. The Programmable Hardware
Program Protect feature allows the user to install the
device with PP tied to VCC, program the entire memory
array in circuit, and then enable the hardware program
protection by programming a PPEN bit in the Program
Protect Register. After this, selected blocks of the
array, including the Program Protect Register itself, are
permanently protected from being erased.

DEVICE ADDRESSING
Following a start condition, the master must output the
address of the slave it is accessing. The first four bits
of the Slave Address Byte are the device type identifier
bits. These must equal “1010”. The next 3 bits are the
device select bits S0, S1, and S2. This allows up to 8
devices to share a single bus. These bits are
compared to the S0, S1, and S2 device select input
pins. The last bit of the Slave Address Byte defines the
operation to be performed. When the R/W bit is a one,
then a read operation is selected. When it is zero then
a program operation is selected. Refer to figure 4.
After loading the Slave Address Byte from the SDA
bus, the device compares the device type bits with the
value “1010” and the device select bits with the status
of the device select input pins. If the compare is not
successful, no acknowledge is output during the ninth
clock cycle and the device returns to the standby mode.
The byte address is either supplied by the master or
obtained from an internal counter, depending on the
operation. When required, the master must supply the
two Address Bytes as shown in figure 4.
The internal organization of the E2 array is 512 sectors
by 32 bytes per sector. The sector address is partially
contained in the Address Byte 1 and partially in bits 7
through 5 of the Address Byte 0. The specific byte
address is contained in bits 4 through 0 of the Address
Byte 0. Refer to figure 4.
