AT45DB321C-CU Product Details

AT45DB321C-CU Overview


In this case, the memory type of the device can be classified as Non-Volatile. Case Tray is available. An embedded 24-TBGA, CSPBGA case surrounds memory ics. It is estimated that the memory size on the chip is 32Mb 528Bytes x 8192 pages. As with most mainstream devices, this one uses FLASH-format memory. Due to its wide temperature range of -40°C~85°C TC, this device is well suited to a wide range of applications that require high performance. With 2.7V~3.6V as the supply voltage, it is capable of handling memory ics. It is recommended to mount it in the Surface Mount mounting type. In order to operate effectively, the memory rotates at a clock frequency within a range of 40MHz. A device's base part number, AT45DB321, is often used in order to identify similar components.
