AT25DQ321-SH-B Product Details
AT25DQ321-SH-B Overview
In this case, the memory type of the device can be classified as Non-Volatile. Case Tube is available. Embedded in the 8-SOIC (0.209, 5.30mm Width) case, memory ics is a single file. There is 32Mb 256Bytes x 16384 pages of memory on the chip. There is a FLASH-format memory used in this device, which is the memory format used by mainstream devices. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. The device is capable of handling a supply voltage of 2.7V~3.6V volts. The recommended mounting type for this device is Surface Mount. The chip is terminated with 8 terminations. This part supports as many as 1 functions for the comprehensive working procedure. It is important to note that the memory has a clock frequency rotation within the range of 100MHz. In this ic memory chip, there is an 8-pin package that encloses the device. There is a note indicating that this memory chip operates at an 3.3V volt supply voltage. It uses Surface Mount mounting, which is an efficient, straightforward mounting method. It is rated 19mA for its nominal supply current when it comes to the memory component. A programming voltage of 2.7V is needed to alter the state of certain nonvolatile memory arrays.
