Features • Serial Peripheral Interface (SPI) Compatible • Supports SPI Modes 0 (0,0) and 3 (1,1) – Data Sheet Describes Mode 0 Operation • Medium-voltage and Standard-voltage Operation – 2.7 (VCC = 2.7V to 5.5V) • Extended Temperature Range –40°C to 125°C • 5.0 MHz Clock Rate • 32-byte Page Mode • Block Write Protection – Protect 1/4, 1/2, or Entire Array SPI Serial • Write Protect (WP) Pin and Write Disable Instructions for Both Hardware and Software Data Protection Extended • Self-timed Write Cycle (2 ms [5V] typical) • High Reliability Temperature – Endurance: One Million Write Cycles – Data Retention: 100 Years EEPROMs • 8-lead PDIP, 8-lead JEDEC SOIC Packages and 8-lead TSSOP Packages Description 8K (1024 x 8) The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial 16K (2048 x 8) 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 32K (4096 x 8) automotive 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 64K (8192 x 8) JEDEC SOIC 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- AT25080A tim
