Features
• 16/32/64/128-Kbit EEPROM: - Internally organized as one 2048/4096/8192/16384 x 8-bit block - Byte or page writes up to 32 bytes - Byte or sequential reads within a block - Self-timed write cycle (5 ms maximum)
• High-Speed I2C Interface: - Industry standard: 1 MHz, 400 kHz and 100 kHz - Output slope control to eliminate ground bounce - Schmitt trigger inputs for noise suppression
• Programmable Hardware Client Address Bits: - Configurable via the Hardware Address Register (HAR)
• Versatile Data Protection Options: - Software write protection via the Write Protection Register (WPR)
• Operating Voltage Range of 1.6V to 5.5V • Low-Power CMOS Technology:
- Write current: 1.0 mA maximum at 5.5V - Read current: 1.0 mA maximum at 5.5V,
1 MHz - Standby Current: 1 µA at 5.5V (I-temp.) • High Reliability: - More than one milli.
