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 8-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 (10 ms max) www.DataSheet4U.com High Reliability – Endurance: One Million Write Cycles – Data Retention: 100 Years 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP Packages SPI Serial Extended Temperature EEPROMs 1K (128 x 8) 2K (256 x 8) 4K (512 x 8) Description The AT25010A/020A/040A provides 1024/2048/4096 bits of serial electrically-erasable programmable read-only memory (EEPROM) organized as 128/256/512 words of 8 bits each. The device is optimized for use in many automotive applications where low-power and low-voltage operation are essential. The AT25010A/020A/040A is available in space-saving 8-pin PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages. The AT25010A/020A/040A 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. Block write protection is enabled by programming...
