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 (AT25128/256), 8-lead EIAJ SOIC (AT25128/256), 8-lead and 16-lead JEDEC SOIC (AT25128), 14-lead TSSOP (AT25128), 20-lead TSSOP (AT25128/256), and 8-lead Leadless Array (AT25256) 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. Table 1. Pin Configuration Pin Name CS SC...
