Idea Packaging Manufacturer. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may cause permanent damage to the device.

These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. The memories behave as slave devices in the retention of 40 years. The ST25x16 operates with I2C protocol with all memory operations synchro- a power supply value as low as 2.

Both Plastic nized by the serial clock. The memories by an acknowledge bit. Table 4. In serting an acknowledge bit during the 9th bit time. Untill the VCC way. The protected area is programma- In the same way, when VCC drops down from the ble to start on any 16 byte boundary. The block in operating voltage to below the POR threshold which the protection starts is selected by the input value, all operations are disabled and the device pins PB0, PB1.

Protection is enabled by setting a will not respond to any command. The SCL input signal is used cally. Serial Data SDA. An hardware Write Control and is used to transfer data in or out of the memory. This feature is usefull to protect with other open drain or open collector signals on the contents of the memory from any erroneous the bus. PB0 and PB1 internal write protection. When unconnected, the input signals select the block in the upper part of WC input is internally read as VIL.

The devices with the memory where write protection starts. Multibyte Write mode of operation, however all other write modes are fully supported. Protect Enable PRE. Figure 3. Table 6. In the Multibyte Write mode only, if accessed bytes are on two consecutive 8 bytes rows 5 address MSB are not constant the maximum programming time is doubled to 20ms.

Table 8. This Input Pulse Voltages 0. The device that controls the Voltages data transfer is known as the master and the other as the slave. The master will always initiate a data Figure 4.

START is identified by a high to 0. A STOP condition at the end low to high transition and the data must change of a Read command forces the standby state. The 8 is used to indicate a successful data transfer. The bits sent after a START condition are made up of a bus transmitter, either master or slave, will release device select of 4 bits that identifie the device type the SDA bus after sending 8 bits of data.

There are three modes both for read and write. They are summarised in Table 4 and described hereafter. A communication between the master and the slave is ended with a STOP condition. The address in the memory. The master sends from one memory acknowledges this and waits for a byte up to 8 bytes of data, which are each acknowledged address. The byte address of 8 bits provides ac- by the memory.

The transfer is terminated by the cess to any of the bytes of one memory block. Writing more than START condition untill the end of the Byte Address 8 bytes in the Multibyte Write mode may modify will not modify data and will NOT be acknowledged data bytes in an adjacent row one row is 16 bytes on data bytes, as in Figure However, the Multibyte Write can properly write up to 16 consecutive bytes only if the first Byte Write.

In the Byte Write mode the master address of these 16 bytes is the first address of the sends one data byte, which is acknowledged by the row, the 15 following bytes being written in the 15 memory. The master then terminates the transfer following bytes of this same row. The master reduced by an ACK polling sequence issued by the sends one up to 16 bytes of data, which are each master. After each byte is The sequence is: transfered, the internal byte address counter 4 — Initial condition: a Write is in progress see Fig- Least Significant Bits only is incremented.

If the memory has terminated the in- the memory will not respond to any request. Figure 8.

The area protected is therefore smaller than The following sequence should be used to set the the content defined in the location 7FFh, by 7 bytes. Figure 9. A dummy write is per- Read operations are independent of the state of the formed to load the address into the address counter MODE signal.
