AT28C256E-20FM/883 Product Details

AT28C256E-20FM/883 Overview


As far as its memory type goes, it falls into the Non-Volatile category. In addition, memory ics is available in a Tube case as well. As you can see, it is embedded in 28-CFlatPack case. It is estimated that the memory size on the chip is 256Kb 32K x 8. The device uses a mainstream EEPROM-format memory. The device's extended operating temperature range of -55°C~125°C TC makes it ideal for many demanding applications. A voltage of 4.5V~5.5V can be supplied to memory ics. It is recommended to mount it in the Surface Mount mounting type. On the chip, there are 28 terminations that are planted. There are 1 functions supported by this part as part of the comprehensive working process. Memory devices such as this one are designed to be powered by 5V and should be used as such. When selecting similar parts for the ic memory chip, AT28C256 is often referred to. It is encased in an 28-pin package that contains this ic memory chip. It is noted that the operating supply voltage of this memory is 5V. This chip uses Surface Mount mounting, a straightforward, high-efficiency method of mounting. As far as its nominal supply current is concerned, this memory component carries a rating of 50mA. Despite all its benefits, this memory chip also offers AUTOMATIC WRITE for improved system performance. This memory chip requires a mere 5V of power. Nonvolatile memory arrays require 5V programming voltage to change their state. This memory chip processes data at a frequency of 200GHz.
