DESCRIPTION
The memory operates with a power supply as low as 3 V. The device is available in wafer form (either sawn or unsawn) and in micromodule form (on film). The memory is compatible with the I2C standard. This is a two wire serial interface that uses a bi-directional data bus and serial clock. The memory carries a built-in 7-bit unique Device Type Identifier code (1010000) in accordance with the I 2C bus definition. Only one memory can be attached to each I2C bus. Wafer Figure 1.

Read and write operations are initiated by a START condition, generated by the bus master.
