In this case, the memory type of the device can be classified as Non-Volatile. It is supplied votage within Tube. An embedded 8-SOIC (0.154, 3.90mm Width) case surrounds memory ics. It is estimated that the memory size on the chip is 4Kb 512 x 8 256 x 16. The device uses a mainstream EEPROM-format memory. This device has an extended operating temperature range of -40°C~85°C TA, so it's perfect for a wide range of demanding applications. The device is capable of handling a supply voltage of 2.7V~5.5V. Its recommended mounting type is Surface Mount. With a clock frequency of 2MHz, the memory rotates on its own. A device's base part number, AT93C66A, is often used in order to identify similar components. An 8-pin package is used to package this memory device. This memory runs on an 5V operating supply voltage. In this chip, Surface Mount mounting is used, a straightforward, high-efficiency mounting method. As far as its nominal supply current is concerned, this memory component carries a rating of 2mA. Temperatures below -40°C should not be used with this memory ics. A temperature of no more than 85°C centigrade is recommended for the component to be operated, otherwise, damage might be inflicted on the component. This part should have a minimum supply voltage of 2.7V. Its operating voltage shall not exceed 5.5V. The frequency of data processing on this memory chip is 1MHz. There is a maximum frequency of up to 1MHz for this memory.
