AT28C256-15UM/883-815 Product Details

AT28C256-15UM/883-815 Overview


There is a Non-Volatile memory type associated with this device. Case Tray is available. 28-BCPGA case encloses it. Memory size on the chip is 256Kb 32K x 8. Memory data is stored in EEPROM-format, which is common in mainstream devices. With an extended designed operating temperature of -55°C~125°C TC, this device is capable of lots of demanding applications. The device is capable of handling a supply voltage of 4.5V~5.5V. The recommended mounting type for memory ics is Through Hole. A total of 28 terminations have been planted on the chip. The comprehensive working procedure is supported by 1 functions in this part. 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. There is a need for a programming voltage of 5V in order to modify the state of some nonvolatile memory arrays.
