The AT24HC04B-PU is a 4-Kbit (512 x 8) I¬=C-compatible serial EEPROM designed for low-voltage operation, with a supply voltage range of 1.8V to 5.5V. It supports multiple I¬=C modes, including standard mode at 100 kHz, fast mode at 400 kHz, and fast mode plus at 1 MHz (4.5V to 5.5V). The device operates within an industrial temperature range of -40¬8C to +85¬8C and features a write-protect pin for hardware data protection. This EEPROM offers an ultra-low active current of 3 mA maximum and a standby current of 18 OºA maximum. It includes a 16-byte page write mode that allows partial page writes, as well as random and sequential read modes. The write cycle is self-timed with a maximum duration of 5 ms. The device boasts high reliability with an endurance of 1,000,000 write cycles and a data retention period of 100 years. It is available in various package options, including 8-lead PDIP, SOIC, and TSSOP, and is compliant with RoHS standards.
