25AA256-I/ST Product Details
25AA256-I/ST Overview
There is a Non-Volatile memory type associated with this device. Tube-cases are available. There is a 8-TSSOP (0.173, 4.40mm Width) case embedded in it. 256Kb 32K x 8 is the chip's memory size. EEPROM-format memory is used in this device, which is a mainstream design. Due to its wide operating temperature range, this device can be used in a wide variety of demanding applications. The supply voltage can be up to 1.8V~5.5V. A Surface Mount mounting type is recommended for this product. The chip is terminated with 8 terminations. In total, this part supports 1 functions. Memory devices such as this one are designed to be powered by 2.5V and should be used as such. In this memory, the clock frequency rotation is within an 10MHz range. When selecting similar parts for the ic memory chip, 25AA256 is often referred to. There are 8 pins on the package of the memory device. A memory device with 8 pins means that it contains 8 memory locations, indicating that it has 8 pins. Using Surface Mount mounting, this chip offers straightforward and high-efficiency mounting. It is rated for a nominal supply current of 6mA for this memory component. Power supplies for this memory chip are merely 2/5V . A SPI-type serial bus is used to carry and transfer data to the CPU through this memory.
