AT28BV64B-20SU Product Details

AT28BV64B-20SU Overview


As far as memory types are concerned, Non-Volatile is considered to be its memory type. Tube-cases are available. 28-SOIC (0.295, 7.50mm Width) case encloses it. 64Kb 8K x 8 is the chip's memory size. This device uses takes advantage of the EEPROM format. The device's extended operating temperature range of -40°C~85°C TC makes it ideal for many demanding applications. There is a voltage range of 2.7V~3.6V for the supply voltage. It is recommended to mount it in the Surface Mount mounting type. On the chip, there are 28 terminations that are planted. The comprehensive working procedure is supported by 1 functions in this part. An 3V supply is required for this ic memory chip to operate properly. In order to select similar parts, typical manufacturers refer to AT28BV64 as the device's base part number. The ic memory chip comes in a package with 28 pins that allows it to be connected to a computer. This memory's operating supply voltage is 3.3V. This chip uses Surface Mount mounting, a straightforward, high-efficiency method of mounting. Memory chip's nominal supply current is 15mA. Despite all its merits, this chip also features 100K ENDURANCE CYCLES; DATA RETENTION = 10 YEARS to boost system performance. There is a need for a programming voltage of 3V in order to modify the state of some nonvolatile memory arrays.
