AT25160

Features Serial Peripheral Interface (SPI) Compatible Supports SPI Modes 0 (0,0) and 3 (1,1) Low-voltage and Standard-voltage Operation – 2.7 (VCC = 2.7V to 5.5V) – 1.8 (VCC = 1.8V to 5.5V) 3.0 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 Typical) High-reliability – Endurance: One Million Write Cycles – Data Retention: 100 Years Automotive Grade Devices Available 8-lead PDIP, 8-lead JEDEC SOIC and 14-lead TSSOP Packages Description The AT25080/160/320/640 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 AT25080/160/320/640 is available in space saving 8-lead PDIP, 8lead JEDEC SOIC and 14-lead TSSOP packages. The AT25080/160/320/640 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.
