AT28C256E-15JU Product Details
AT28C256E-15JU Overview
As far as memory types are concerned, Non-Volatile is considered to be its memory type. You can get memory ics in a Tube case. As you can see, it is embedded in 32-LCC (J-Lead) case. On the chip, there is an 256Kb 32K x 8 memory, which is the size of the chip's memory. In this device, the memory is of the EEPROM-format, which is a popular format in the mainstream computing sector. The device's extended operating temperature range of -40°C~85°C TC makes it ideal for many demanding applications. A voltage of 4.5V~5.5V is possible to be applied to the supply. There is a recommendation that Surface Mount mounting type should be used for this product. As you can see from the diagram, the chip is planted with 32 terminations. In total, this part supports 1 functions. The memory device is designed to be supplied with an 5V volt power supply in order to operate properly. It is common to select similar parts by referring to the device's base part number, AT28C256. A 32-pin package containing this memory device is used to house this device. A voltage of 5V is noted as the operating supply voltage for this memory. It uses Surface Mount mounting, which is an efficient, straightforward mounting method. Memory chip's nominal supply current is 50mA. Although it has all the merits this chip has, it is also equipped with AUTOMATIC WRITE to give a performance boost to the system. This memory chip requires only 5V of power. There is a need for a programming voltage of 5V in order to modify the state of some nonvolatile memory arrays. There is an 5MHz frequency with which this memory chip processes data.
