AT28C256-25DM/883-815 Product Details

AT28C256-25DM/883-815 Overview


As far as memory types are concerned, Non-Volatile is considered to be its memory type. It is available in a case with a Tube shape. The case is embedded in 28-CDIP (0.600, 15.24mm). On the chip, there is an 256Kb 32K x 8 memory, which is the size of the chip's memory. The device uses a mainstream EEPROM-format memory. Due to its wide operating temperature range, this device can be used in a wide variety of demanding applications. A voltage of 4.5V~5.5V can be supplied to memory ics. There is a recommendation that Through Hole mounting type should be used for this product. There are 28 terminations on the chip. There are 1 functions supported by this part as part of the comprehensive working process. In order to operate this memory device, it must be supplied with 5V of power. Despite all the merits of this chip, it also has AUTOMATIC WRITE to boost system performance. The programming voltage required for certain nonvolatile memory arrays is 5V.
