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) This input signal is used to protect the memory against write instructions. When write protect (W) is held low, write instructions (WRSR, WRITE) are ignored. No action on this signal can interrupt a write cycle that has already started.

R1EX25002Axx00A/R1EX25004Axx00A 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 Enable (WREN) Sequence

R1EX25002Axx00A/R1EX25004Axx00A 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: Power-up WRDI instruction execution WRSR instruction completion WRITE instruction completion WRITE protect (W) is driven low

R1EX25002Axx00A/R1EX25004Axx00A 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. Read Status Register (RDSR) Sequence

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.

R1EX25002Axx00A/R1EX25004Axx00A 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 contents of 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. Write Status Register (WRSR) Sequence

R1EX25002Axx00A/R1EX25004Axx00A 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). The most significant address (A8) should be sent as fifth bit in the instruction byte. 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. Read from Memory Array (READ) Sequence

R1EX25002Axx00A/R1EX25004Axx00A Write to Memory Array (WRITE): 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. If Write Protect (W) is low

Data Protect
The Block Protect bits (BP1, BP0) define the area of memory that is protected against the execution of write cycle, as summarized in the following table. When Write Protect (W) is driven low, write to memory array (WRITE) and write status register (WRSR) are disabled, and WEL bit is reset. Write Protected Block Size

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. Hold Condition Activation

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 s/V. * When WRSR or WRITE instruction is executed before VCC turns off, VCC should be turned off after waiting write cycle time (tW).
