Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a age Write Buffer, and then writing all data to non volatile memory in one internal write cycle. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count. External address pins make it possible to address up to eight NV2402, four NV2404, two NV2408 and one NV2416 device on the same bus.

4 NV2402WF, NV2404WF, NV2408WF, NV2416WF ower On Reset (OR) Each NV24xx* incorporates ower On Reset (OR) circuitry which protects the internal logic against powering up in the wrong state. NV24xx device will power up into tandby mode after V exceeds the OR trigger level and will power down into Reset mode when V drops below the OR trigger level. his bi directional OR feature protects the device against brown out failure following a temporary loss of power. *For common features, the NV2402/04/08/16 will be referred to as NV24xx. in Description L: he erial lock input pin accepts the erial lock generated by the Master. D: he erial Data I/O pin receives input data and transmits data stored in EEROM. In transmit mode, this pin is open drain. Data is acquired on the positive edge, and is delivered on the negative edge of L. 0, 1 and 2: he ddress inputs set the device address when cascading multiple devices. When not driven, these pins are pulled LOW internally. W: he Write rotect input pin inhibits all write operations, when pulled HIGH. When not driven, this pin is pulled LOW internally. Functional Description he NV24xx supports the Inter Integrated ircuit (I 2 ) Bus data transmission protocol, which defines a device that sends data to the bus as a transmitter and a device receiving data as a receiver. Data flow is controlled by a Master device, which generates the serial clock and all R and O conditions. he NV24xx acts as a lave device. Master and lave alternate as either transmitter or receiver. I 2 Bus rotocol he I 2 bus consists of two wires, L and D. he two wires are connected to the V supply via pull up resistors. Master and lave devices connect to the 2 wire bus via their respective L and D pins. he transmitting device pulls down the D line to transmit a 0 and releases it to transmit a 1. Data transfer may be initiated only when the bus is not busy (see haracteristics). During data transfer, the D line must remain stable while the L line is high. n D transition while L is high will be interpreted as a R or O condition (Figure 2). he R condition precedes all commands. It consists of a HIGH to LOW transition on D while L is HIGH. he R acts as a wake up call to all receivers. bsent a R, a lave will not respond to commands. he O condition completes all commands. It consists of a LOW to HIGH transition on D while L is HIGH. NOE: he I/O pins of NV24xx do not obstruct the L and D lines if the V supply is switched off. During power up, the L and D pins (connected with pull up resistors to V) will follow the V monotonically from V (0 V) to nominal V value, regardless of pull up resistor value. he delta between the V and the instantaneous voltage levels during power ramping will be determined by the relation between bus time constant (determined by pull up resistance and bus capacitance) and actual V ramp rate. Device ddressing he Master initiates data transfer by creating a R condition on the bus. he Master then broadcasts an 8 bit serial lave address. For normal Read/Write operations, the first 4 bits of the lave address are fixed at 1010 (h). he next 3 bits are used as programmable address bits when cascading multiple devices and/or as internal address bits. he last bit of the slave address, R/W, specifies whether a Read (1) or Write (0) operation is to be performed. he 3 address space extension bits are assigned as illustrated in Figure 3. 2, 1 and 0 must match the state of the external address pins, and a 10, a 9 and a 8 are internal address bits. cknowledge fter processing the lave address, the lave responds with an acknowledge () by pulling down the D line during the 9th clock cycle (Figure 4). he lave will also acknowledge the address byte and every data byte presented in Write mode. In Read mode the lave shifts out a data byte, and then releases the D line during the 9 th clock cycle. s long as the Master acknowledges the data, the lave will continue transmitting. he Master terminates the session by not acknowledging the last data byte (No) and by issuing a O condition. Bus timing is illustrated in Figure 5. 4

6 NV2402WF, NV2404WF, NV2408WF, NV2416WF WRIE OERION Byte Write In Byte Write mode, the Master sends the R condition and the lave address with the R/W bit set to zero to the lave. fter the lave generates an acknowledge, the Master sends the byte address that is to be written into the address pointer of the NV24xx. fter receiving another acknowledge from the lave, the Master transmits the data byte to be written into the addressed memory location. he NV24xx device will acknowledge the data byte and the Master generates the O condition, at which time the device begins its internal Write cycle to nonvolatile memory (Figure 6). While this internal cycle is in progress (t WR ), the D output will be tri stated and the NV24xx will not respond to any request from the Master device (Figure 7). age Write he NV24xx writes up to 16 bytes of data in a single write cycle, using the age Write operation (Figure 8). he age Write operation is initiated in the same manner as the Byte Write operation, however instead of terminating after the data byte is transmitted, the Master is allowed to send up to fifteen additional bytes. fter each byte has been transmitted the NV24xx will respond with an acknowledge and internally increments the four low order address bits. he high order bits that define the page address remain unchanged. If the Master transmits more than sixteen bytes prior to sending the O condition, the address counter wraps around to the beginning of page and previously transmitted data will be overwritten. Once all sixteen bytes are received and the O condition has been sent by the Master, the internal Write cycle begins. t this point all received data is written to the NV24xx in a single write cycle. cknowledge olling he acknowledge () polling routine can be used to take advantage of the typical write cycle time. Once the stop condition is issued to indicate the end of the host s write operation, the NV24xx initiates the internal write cycle. he polling can be initiated immediately. his involves issuing the start condition followed by the slave address for a write operation. If the NV24xx is still busy with the write operation, No will be returned. If the NV24xx has completed the internal write operation, an will be returned and the host can then proceed with the next read or write operation. Hardware Write rotection With the W pin held HIGH, the entire memory is protected against Write operations. If the W pin is left floating or is grounded, it has no impact on the operation of the NV24xx. he state of the W pin is strobed on the last falling edge of L immediately preceding the first data byte (Figure 9). If the W pin is HIGH during the strobe interval, the NV24xx will not acknowledge the data byte and the Write request will be rejected. Delivery tate he NV24xx is shipped erased, i.e., all bytes are FFh. BU IVIY: MER R LVE DDRE DDRE D a 7 a 0 d 7 d 0 O LVE Figure 6. Byte Write equence 6

8 NV2402WF, NV2404WF, NV2408WF, NV2416WF Immediate Read Upon receiving a lave address with the R/W bit set to 1, the NV24xx will interpret this as a request for data residing at the current byte address in memory. he NV24xx will acknowledge the lave address, will immediately shift out the data residing at the current address, and will then wait for the Master to respond. If the Master does not acknowledge the data (No) and then follows up with a O condition (Figure 10), the NV24xx returns to tandby mode. elective Read elective Read operations allow the Master device to select at random any memory location for a read operation. he Master device first performs a dummy write operation by sending the R condition, slave address and byte RED OERION address of the location it wishes to read. fter the NV24xx acknowledges the byte address, the Master device resends the R condition and the slave address, this time with the R/W bit set to one. he NV24xx then responds with its acknowledge and sends the requested data byte. he Master device does not acknowledge the data (No) but will generate a O condition (Figure 11). equential Read If during a Read session, the Master acknowledges the 1 st data byte, then the NV24xx will continue transmitting data residing at subsequent locations until the Master responds with a No, followed by a O (Figure 12). In contrast to age Write, during equential Read the address count will automatically increment to and then wrap around at end of memory (rather than end of page).
