Description
The AT24C128/256 provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device’s cascadable feature allows up to 4 devices to share a common Two-wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The devices are available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP (24C128), 8-lead TSSOP, 8-lead SOIC Array Package and 8-ball dBGA2 packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.

Comparison
Advantages1. Low-voltage and standard-voltage operation options (2.7V to 5.5V and 1.8V to 3.6V) provide flexibility for different power requirements.
2. Internally organized memory with high density (16,384 x 8 and 32,768 x 8) allows for efficient storage of data.
3. Two-wire serial interface enables easy integration with other devices.
4. Schmitt trigger and filtered inputs help suppress noise for reliable data transfer.
5. High reliability with one million write cycles endurance and 40 years data retention.
6. Available in a variety of package options for different design requirements.Disadvantages1. Limited maximum frequency compatibility, with 1 MHz for 5V, 400 kHz for 2.7V and 2.5V, and 100 kHz for 1.8V.
2. Self-timed write cycle has a maximum of 5 ms, which may cause delay in write operations.
3. Extended temperature and lead-free/halogen-free devices may have limited availability and higher cost. -
