As far as its memory type goes, it falls into the Non-Volatile category. There is a Tape & Reel (TR) case available. An embedded 8-SOIC (0.154, 3.90mm Width) case surrounds memory ics. This chip has an 1Kb 128 x 8 size of memory on it, so a lot of data can be stored on it. There is a EEPROM-format memory used in this device, which is the memory format used by mainstream devices. The device's extended operating temperature range of -40°C~85°C TC makes it ideal for many demanding applications. The device is capable of handling a supply voltage of 1.7V~3.6V volts. As far as the mounting type is concerned, Surface Mount is recommended. It is planted on the chip with 8 terminations. There are 1 functions supported by this part as part of the comprehensive working process. A voltage of 1.8V is required for the operation of this memory device. It has a clock frequency of 125kHz. Similar parts are frequently selected using the ic memory chip's base part number, AT21CS01. There are 8 pins on the package of the memory device. A 1-WIRE-type serial bus is used to carry and transfer data to the CPU through this memory.
