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. SPI Serial EEPROMs 128K (16,384 x 8) 256K (32,768 x 8) AT25128A AT25256A Not Recommended for New Design The AT25128A/256A is enabled through the Chip Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely self-timed, and no separate Erase cycle is required before Write. 8-lead SOIC 8-lead PDIP CS SO WP GND 1 2 3 4 8 7 6 5 VCC HOLD SCK SI CS SO WP GND 1 2 3 4 8 7 6 5 8-lead Ultra Thin SAP VCC HOLD SCK SI 8 7 6 5 1 2 3 4 Bottom View CS SO WP GND 8-lead TSSOP CS VCC SO HOLD WP SCK GND SI 1 2 3 4 8 7 6 5 VCC HOLD SCK SI 8-ball dBGA2 VCC 8 1 CS HOLD SCK SI 7 2 6 3 5 4 SO WP GND Bottom View 3368J–SEEPR–06/07
