AT25256B-SSHL-T Product Details
AT25256B-SSHL-T Overview
Non-Volatile is the type of memory it has. In addition, memory ics is available in a Tape & Reel (TR) case as well. The 8-SOIC (0.154, 3.90mm Width) case contains it. 256Kb 32K x 8 is the chip's memory size. EEPROM-format memory is used in this device, which is a mainstream design. A wide operating temperature range makes this device ideal for a variety of demanding applications. The device is capable of handling a supply voltage of 1.8V~5.5V volts. The recommended mounting type for this device is Surface Mount. A total of 8 terminations have been planted on the chip. The comprehensive working procedure of this part involves 1 functions. In order to power this memory device, 5V will be necessary. In order to operate effectively, the memory rotates at a clock frequency within a range of 20MHz. Similar parts are frequently selected using AT25256, the device's base part number. The ic memory chip comes in a package with 8 pins that allows it to be connected to a computer. This chip uses Surface Mount mounting, a straightforward, high-efficiency method of mounting. Memory chip's nominal supply current is 10mA. 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.
