1 / 24 page 1 Features • Serial Peripheral Interface (SPI) Compatible • Supports SPI Modes 0 (0,0) and 3 (1,1) – Datasheet Describes Mode 0 Operation • Low-voltage and Standard-voltage Operation – 2.7 (V CC = 2.7V to 5.5V) – 1.8 (VCC = 1.8V to 5.5V) • 20 MHz Clock Rate (5V) • 32-byte Page Mode • Block Write Protection – Protect 1/4, 1/2, or Entire Array • Write Protect (WP) Pin and Write Disable Instructions for Both Hardware and Software Data Protection • Self-timed Write Cycle (5 ms max) • High Reliability – Endurance: One Million Write Cycles – Data Retention: 100 Years • Automotive Devices Available • 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), and 8- lead TSSOP Packages • Die Sales: Wafer Form, Waffle Pack, and Bumped Wafers Description The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial electrically-erasable programmable read-only memory (EEPROM) organized as 1024/2048/4096/8192 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 AT25080A/160A/320A/640A is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP, 8-lead Ultra Thin Mini-MAP (MLP 2x3) and 8- lead TSSOP packages. The AT25080A/160A/320A/640A is enabled through the Chip Select pin (CS) and accessed via a three-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. Table 1.
