In this case, the memory type of the device can be classified as Non-Volatile. The case comes in the Tube style. 8-TSSOP (0.173, 4.40mm Width) case encloses it. This chip has an 4Kb 256 x 16 size of memory on it, so a lot of data can be stored on it. This device utilizes a EEPROM format memory which is of mainstream design. The device's extended operating temperature range of 0°C~70°C TA makes it ideal for many demanding applications. A supply voltage of 4.5V~5.5V can be applied to it. It is recommended that the mounting type be Surface Mount. A clock frequency rotation within 250kHz is used for the ic memory chip to rotate data. As the base part number for the device, FM93C66 is frequently used to select similar items. In this ic memory chip, there is an 8-pin package that encloses the device. The operating supply voltage of this memory chip is noted to be 5V.
