25AA640T-I/SN Overview

There is a memory type Non-Volatile for this type of device. The case comes in the Tape & Reel (TR) style. As you can see, it is embedded in 8-SOIC (0.154, 3.90mm Width) case. It is estimated that the memory size on the chip is 64Kb 8K x 8. There is a mainstream memory format used by this device, which is called EEPROM-format memory. A wide operating temperature range makes this device ideal for a variety of demanding applications. A voltage of 1.8V~5.5V is possible to be applied to the supply. Its recommended mounting type is Surface Mount. As you can see from the diagram, the chip is planted with 8 terminations. There are 1 functions supported by this part as part of the comprehensive working process. This ic memory chip is designed to be supplied with 2.5V. In this memory, the clock frequency rotation is within an 1MHz range. Similar parts are frequently selected using the ic memory chip's base part number, 25AA640. The memory device is enclosed in a package with an 8-pin connector. There are 8 pins on this memory device, which indicates it has 8 memory locations in it. In terms of its nominal supply current, this memory component is rated at 5mA. In spite of all the merits this chip has, it also features 1000K ERASE/WRITE CYCLES; DATA RETENTION > 200 YEARS to level up system performance. In terms of power requirements, this memory chip uses only 2/5V . Integrated into this memory is a SPI-type serial bus that facilitates data transmission to the CPU.
