In terms of its memory type, it can be classified as Non-Volatile. Case Tape & Reel (TR) is available. 8-SOIC (0.154, 3.90mm Width) case encloses it. 1Kb 128 x 8 is the chip's memory size. In this device, the memory is of the EEPROM-format, which is a popular format in the mainstream computing sector. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. The supply voltage can be up to 1.7V~3.6V. It is recommended that the mounting type be Surface Mount. As you can see from the diagram, the chip is planted with 8 terminations. This part supports as many as 1 functions for the comprehensive working procedure. Memory devices such as this one are designed to be powered by 1.8V and should be used as such. It is important to note that the memory has a clock frequency rotation within the range of 125kHz. When selecting similar parts for the ic memory chip, AT21CS01 is often referred to. A 8-pin package containing this memory device is used to house this device. The 1-WIRE type serial bus this memory integrates with is helpful to carry and transfer data to the CPU.
