Atmel AT25128A
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.- Min Voltage : 1.8V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
