AT28HC256-90SU Product Details
AT28HC256-90SU Overview
Non-Volatile is the type of memory it has. There is a Tube case available. As you can see, it is embedded in 28-SOIC (0.295, 7.50mm Width) case. Memory size on the chip is 256Kb 32K x 8. This device uses takes advantage of the EEPROM format. A wide operating temperature range makes this device ideal for a variety of demanding applications. The supply voltage can be up to 4.5V~5.5V. As far as the mounting type is concerned, Surface Mount is recommended. On the chip, there are 28 terminations that are planted. The comprehensive working procedure is supported by 1 functions in this part. Memory devices such as this one are designed to be powered by 5V and should be used as such. In order to select similar parts, typical manufacturers refer to AT28HC256 as the device's base part number. There are 28 pins on the package of the memory device. It is noted that the operating supply voltage of this memory is 5V. Chips such as this one are mounted using Surface Mount mounting, a straightforward method of mounting that is effective. As far as its nominal supply current is concerned, this memory component carries a rating of 80mA. As for the power supply, this memory chip only needs 5V . Nonvolatile memory arrays require 5V programming voltages to change their states. Using this memory chip, you will be able to process data at a speed of 90GHz times per second.
