Pin Function
Serial data output (Q)
This output signal is used to transfer data serially out of the device. Data is shifted out on the falling edge of serial
clock (C).
Serial data input (D)
This input signal is used to transfer data serially into the device. It receives instructions, addresses, and the data to be
written. Values are latched on the rising edge of serial clock (C).
Serial clock (C)
This input signal provides the timing of the serial interface. Instructions, addresses, or data present at serial data input
(D) are latched on the rising edge of serial clock (C). Data on serial data output (Q) changes after the falling edge of
serial clock (C).
Chip select (S)
When this input signal is high, the device is deselected and serial data output (Q) is at high impedance. Unless an
internal write cycle is in progress, the device will be in the standby mode. Driving chip select (S) low enables the
device, placing it in the active power mode. After power-up, a falling edge on chip select (S) is required prior to the
start of any instruction.
Hold (HOLD)
The hold (HOLD) signal is used to pause any serial communications with the device without deselecting the device.
During the hold condition, the serial data output (Q) is high impedance, and serial data input (D) and serial clock (C)
are don’t care. To start the hold condition, the device must be selected, with chip select (S) driven low.
Write protect (W)
The main purpose of this input signal is to freeze the size of the area of memory that is protected against write
instructions (as specified by the values in the BP1 and BP0 bits of the status register). This pin must be driven either
high or low, and must be stable during all write operations.

WIP bit: The Write In Progress (WIP) bit indicates whether the memory is busy with a Write or Write Status Register
cycle.
WEL bit: The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch.
BP1, BP0 bits: The Block Protect (BP1, BP0) bits are non-volatile. They define the size of the area to be software
protected against Write instructions.
SRWD bit: The Status Register Write Disable (SRWD) bit is operated in conjunction with the write protect (W) signal.
The Status Register Write Disable (SRWD) bit and write protect (W) signal allow the device to be put in the Hardware
Protected mode. In this mode, the non-volatile bits of the Status Register (SRWD, BP1, BP0) become read-only bits.
Instructions
Each instruction starts with a single-byte code, as summarized in the following table. If an invalid instruction is sent
(one not contained in the following table), the device automatically deselects itself.

Write Enable (WREN):
The Write Enable Latch (WEL) bit must be set prior to each WRITE and WRSR instruction. The only way to do this is
to send a Write Enable instruction to the device. As shown in the following figure, to send this instruction to the
device, chip select (S) is driven low, and the bits of the instruction byte are shifted in, on serial data input (D). The
device then enters a wait state. It waits for the device to be deselected, by chip select (S) being driven high.

Write Disable (WRDI):
One way of resetting the Write Enable Latch (WEL) bit is to send a Write Disable instruction to the device. As shown
in the following figure, to send this instruction to the device, chip select (S) is driven low, and the bits of the instruction
byte are shifted in, on serial data input (D).
The device then enters a wait state. It waits for the device to be deselected, by chip select (S) being driven high. The
Write Enable Latch (WEL) bit, in fact, becomes reset by any of the following events:

Read Status Register (RDSR):
The Read Status Register (RDSR) instruction allows the Status Register to be read. The Status Register may be read at
any time, even while a Write or Write Status Register cycle is in progress. When one of these cycles is in progress, it is
recommended to check the Write In Progress (WIP) bit before sending a new instruction to the device. It is also
possible to read the Status Register continuously, as shown in the following figure.

The status and control bits of the Status Register are as follows:
WIP bit: The Write In Progress (WIP) bit indicates whether the memory is busy with a Write or Write Status Register
cycle. When set to 1, such a cycle is in progress. When reset to 0, no such cycles are in progress.
WEL bit: The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch. When set to 1, the
internal Write Enable Latch is set. When set to 0, the internal Write Enable Latch is reset and no Write or Write Status
Register instructions are accepted.
BP1, BP0 bits: The Block Protect (BP1, BP0) bits are non-volatile. They define the size of the area to be software
protected against Write instructions. These bits are written with the Write Status Register (WRSR) instruction. When
one or both of the Block Protect (BP1, BP0) bits are set to 1, the relevant memory area (as defined in the Status
Register Format table) becomes protected against Write (WRITE) instructions. The Block Protect (BP1, BP0) bits can
be written provided that the Hardware Protected mode has not been set.
SRWD bit: The Status Register Write Disable (SRWD) bit is operated in conjunction with the write protect (W) signal.
The Status Register Write Disable (SRWD) bit and write protect (W) signal allows the device to be put in the Hardware
Protected mode (When the Status Register Write Disable (SRWD) bit is set to 1, and write protect (W) signal is driven
low). In this mode, the non-volatile bits of the Status Register (SRWD, BP1, BP0) become read-only bits and the Write
Status Register (WRSR) instruction is no longer accepted for execution.
Rev.3.00, Jul.06.2005, page 12 of 20
HN58X2532I/HN58X2564I
Write Status Register (WRSR):
The Write Status Register (WRSR) instruction allows new values to be written to the Status Register. Before it can be
accepted, a Write Enable (WREN) instruction must previously have been executed. After the Write Enable (WREN)
instruction has been decoded and executed, the device sets the Write Enable Latch(WEL). The instruction sequence is
shown in the following figure. The Write Status Register (WRSR) instruction has no effect on b6, b5, b4, b1 and b0 of
the Status Register. b6, b5 and b4 are always read as 0. Chip select (S) must be driven high after the rising edge of
serial clock (C) that latches in the eighth bit of the data byte, and before the next rising edge of serial clock (C).
Otherwise, the Write Status Register (WRSR) instruction is not executed. As soon as chip select (S) is driven high, the
self-timed Write Status Register cycle (whose duration is tW) is initiated. While the Write Status Register cycle is in
progress, the Status Register may still be read to check the value of the Write In Progress (WIP) bit. The Write In
Progress (WIP) bit is 1 during the self-timed Write Status Register cycle, and is 0 when it is completed. When the
cycle is completed, Write Enable Latch (WEL) is reset. The Write Status Register (WRSR) instruction allows the user
to change the values of the Block Protect (BP1, BP0) bits, to define the size of the area that is to be treated as read-only,
as defined in the Status Register Format table.
The Write Status Register (WRSR) instruction also allows the user to set or reset the Status Register Write Disable
(SRWD) bit in accordance with the write protect (W) signal. The Status Register Write Disable (SRWD) bit and write
protect (W) signal allows the device to be put in the Hardware Protected Mode (HPM). The Write Status Register
(WRSR) instruction is not executed once the Hardware Protected Mode (HPM) is entered.
The contents of the Status Register Write Disable (SRWD) and Block Protect (BP1, BP0) bits are frozen at their current
values just before the start of the execution of the Write Status Register (WRSR) instruction. The new, updated values
take effect at the moment of completion of the execution of Write Status Register (WRSR) instruction.

HN58X2532I/HN58X2564I
Read from Memory Array (READ):
As shown in the following figure, to send this instruction to the device, chip select (S) is first driven low. The bits of
the instruction byte and the address bytes are then shifted in, on serial data input (D). The addresses are loaded into an
internal address register, and the byte of data at that address is shifted out, on serial data output (Q).
If chip select (S) continues to be driven low, the internal address register is automatically incremented, and the byte of
data at the new address is shifted out.
When the highest address is reached, the address counter rolls over to zero, allowing the Read cycle to be continued
indefinitely. The whole memory can, therefore, be read with a single READ instruction.
The Read cycle is terminated by driving chip select (S) high. The rising edge of the chip select (S) signal can occur at
any time during the cycle. The addressed first byte can be any byte within any page. The instruction is not accepted,
and is not executed, if a Write cycle is currently in progress.

As shown in the following figure, to send this instruction to the device, chip select (S) is first driven low. The bits of
the instruction byte, address byte, and at least one data byte are then shifted in, on serial data input (D).
The instruction is terminated by driving chip select (S) high at a byte boundary of the input data. In the case of the
following figure, this occurs after the eighth bit of the data byte has been latched in, indicating that the instruction is
being used to write a single byte. The self-timed Write cycle starts, and continues for a period tWC (as specified in AC
Characteristics). At the end of the cycle, the Write In Progress (WIP) bit is reset to 0.
If, though, chip select (S) continues to be driven low, as shown in the following figure, the next byte of the input data is
shifted in, so that more than a single byte, starting from the given address towards the end of the same page, can be
written in a single internal Write cycle.
Each time a new data byte is shifted in, the least significant bits of the internal address counter are incremented. If the
number of data bytes sent to the device exceeds the page boundary, the internal address counter rolls over to the
beginning of the page, and the previous data there are overwritten with the incoming data. (The page size of these
device is 32 bytes).
The instruction is not accepted, and is not executed, under the following conditions:
 If the Write Enable Latch (WEL) bit has not been set to 1 (by executing a Write Enable instruction just before)
 If a Write cycle is already in progress
 If the addressed page is in the region protected by the Block Protect (BP1 and BP0) bits.

Data Protect
The protection features of the device are summarized in the following table. When the Status Register Write Disable
(SRWD) bit of the Status Register is 0 (its initial delivery state), it is possible to write to the Status Register provided
that the Write Enable Latch (WEL) bit has previously been set by a Write Enable (WREN) instruction, regardless
weather write protect (W) is driven high or low.
When the Status Register Write Disable (SRWD) bit of the Status Register is set to 1, two cases need to be considered,
depending on the state of write protect (W):
 If write protect (W) is driven high, it is possible to write to the Status Register provided that the Write Enable
Latch (WEL) bit has previously been set by a Write Enable (WREN) instruction.
 If write protect (W) is driven low, it is not possible to write to the Status Register even if the Write Enable Latch
(WEL) bit has previously been set by a Write Enable (WREN) instruction. (Attempts to write to the Status
Register are rejected, and are not accepted for execution). As a consequence, all the data bytes in the memory
area that are software protected (SPM) by the Block Protect (BP1, BP0) bits of the Status Register, are also
hardware protected against data modification.
Regardless of the order of the two events, the Hardware Protected Mode (HPM) can be entered:
 By setting the Status Register Write Disable (SRWD) bit after driving write protect (W) low.
 By driving write protect (W) low after setting the Status Register Write Disable (SRWD) bit.
The only way to exit the Hardware Protected Mode (HPM) once entered is to pull write protect (W) high.
If write protect (W) is permanently tied high, the Hardware Protected Mode (HPM) can never be activated, and only the
Software Protected Mode (SPM), using the Block Protect (BP1, BP0) bits of the Status Register, can be used.

Hold Condition
The hold (HOLD) signal is used to pause any serial communications with the device without resetting the clocking
sequence.
During the hold condition, the serial data output (Q) is high impedance, and serial data input (D) and serial clock (C)
are don’t care.
To enter the hold condition, the device must be selected, with chip select (S) low.
Normally, the device is kept selected, for the whole duration of the hold condition. Deselecting the device while it is in
the hold condition, has the effect of resetting the state of the device, and this mechanism can be used if it is required to
reset any processes that had been in progress.
The hold condition starts when the hold (HOLD) signal is driven low at the same time as serial clock (C) already being
low (as shown in the following figure).
The hold condition ends when the hold (HOLD) signal is driven high at the same time as serial clock (C) already being
low.
The following figure also shows what happens if the rising and falling edges are not timed to coincide with serial clock
(C) being low.

Notes
Data Protection at VCC On/Off
When VCC is turned on or off, noise on S inputs generated by external circuits (CPU, etc) may act as a trigger and turn
the EEPROM to unintentional program mode. To prevent this unintentional programming, this EEPROM have a power
on reset function. Be careful of the notices described below in order for the power on reset function to operate
correctly.
• S should be fixed to VCC during VCC on/off. Low to high or high to low transition during VCC on/off may
cause the trigger for the unintentional programming.
• VCC should be turned on/off after the EEPROM is placed in a standby state.
• VCC should be turned on from the ground level (VSS) in order for the EEPROM not to enter the unintentional
programming mode.
• VCC turn on speed should be slower than 10 µs/V.
• When WRSR or WRITE instruction is executed before VCC turns off, VCC should be turned off after waiting
write cycle time (tW).
