25AA640XT-I/ST Product Details

25AA640XT-I/ST Overview


There is a Non-Volatile memory type associated with this device. You can get memory ics in a Tape & Reel (TR) case. The file is embedded in a 8-TSSOP (0.173, 4.40mm Width) case. On the chip, there is an 64Kb 8K x 8 memory, which is the size of the chip's memory. There is a EEPROM-format memory used in this device, which is the memory format used by mainstream devices. This device has an extended operating temperature range of -40°C~85°C TA, so it's perfect for a wide range of demanding applications. It is supplied votage within 1.8V~5.5V. A Surface Mount mounting type is recommended for this product. It is planted on the chip with 8 terminations. The comprehensive working procedure of this part involves 1 functions. There is a requirement for 2.5V to be supplied to this ic memory chip in order to operate. It is important to note that the memory has a clock frequency rotation within the range of 1MHz. In order to select similar parts, typical manufacturers refer to 25AA640 as the device's base part number. An 8-pin package is used to package this memory device. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. This chip is configured to use Surface Mount mounting, a straight forward, high-efficiency mounting fashion. As far as its nominal supply current is concerned, this memory component carries a rating of 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. As for power supplies, this memory chip requires just 2/5V . By integrating with the SPI-type serial bus, this memory transmits data to the processor.
