AT28C256-20DM/883-815 Product Details

AT28C256-20DM/883-815 Overview


Non-Volatile is its memory type. Tube-cases are available. It is available in 28-CDIP (0.600, 15.24mm) case. There is 256Kb 32K x 8 of memory on the chip. In this device, the memory is of the EEPROM-format, which is a popular format in the mainstream computing sector. Featuring an extended operating temperature range of -55°C~125°C TC, this device allows it to be used in a variety of demanding applications. A voltage of 4.5V~5.5V can be supplied to memory ics. The recommended mounting type for memory ics is Through Hole. It is planted on the chip with 28 terminations. In total, this part supports 1 functions. In order to function properly, this ic memory chip should be powered by a voltage of 5V. The memory chip also offers AUTOMATIC WRITE to level up system performance despite its merits. A programming voltage of 5V is required to alter the state of certain nonvolatile memory arrays.
