EEPROM Serial-SPI 256Kbit 32K x 8 2.5V/3.3V/5V 8Pin TSSOP
Description
The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable programmable read only memory EEPROM organized as 16,384/32,768 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The devices are available in space saving 8-lead PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead SAP packages. In addition, the entire family is available in 2.7V 2.7V to 5.5V and 1.8V 1.8V to 5.5V versions.
