AT28C256-15TU Product Details

AT28C256-15TU Overview


Non-Volatile is its memory type. You can get memory ics in a Tray case. An embedded 28-TSSOP (0.465, 11.80mm Width) case surrounds memory ics. Memory size on the chip is 256Kb 32K x 8. This device uses takes advantage of the EEPROM format. With an extended designed operating temperature of -40°C~85°C TC, this device is capable of lots of demanding applications. There is a voltage range of 4.5V~5.5V for the supply voltage. The recommended mounting type for memory ics is Surface Mount. There are 28 terminations on the chip. It supports up to 1 functions for comprehensive operation. There is a requirement for 5V to be supplied to this ic memory chip in order to operate. Similar parts are frequently selected using the ic memory chip's base part number, AT28C256. The ic memory chip comes in a package with 28 pins that allows it to be connected to a computer. It is noted that the operating supply voltage of this memory is 5V. Memory chips configured with Surface Mount mounting achieve high efficiency and simplicity. In terms of its nominal supply current, this memory component is rated at 50mA. This memory chip requires a mere 5V of power. A programming voltage of 5V is needed to alter the state of certain nonvolatile memory arrays. The frequency of data processing on this memory chip is 150GHz.
