The document describes the features and characteristics of the AT24C16B product, which is a serial electrically erasable and programmable read-only memory (EEPROM). It is optimized for low-power and low-voltage operation, making it suitable for industrial and commercial applications.
The AT24C16B serial EEPROM provides 16 Kbits (2048 × 8) of non‑volatile memory with a two‑wire I²C‑compatible interface. It operates from 1.8 V to 5.5 V and is available in a variety of compact packages such as 8‑lead PDIP, SOIC, TSSOP, ULA, and BGA. Features include Schmitt‑triggered inputs, write‑protect pin, partial page writes, and a 5 ms maximum write cycle.
The device includes detailed pin descriptions, timing diagrams, and electrical characteristics. Absolute maximum ratings, DC and AC characteristics, and bus timing specifications are provided for reliable integration into industrial and commercial designs. Revision history and contact information for Atmel support are also included.
| Supply Voltage | 1.8 V to 5.5 V |
|---|---|
| Read Supply Current (400 kHz, 1.8 V) | 1.0 mA typical |
| Write Supply Current (400 kHz, 5 V) | 2.0 mA typical |
| Write Cycle Time | 5 ms max |
| Endurance | 1 Million write cycles |
The device operates from 1.8 V up to 5.5 V.
It is rated for up to 1 million write cycles.
The write cycle time is specified as 5 ms maximum.
The WP (Write Protect) pin enables hardware data protection; grounding it allows normal read/write, while tying it to VCC enables protection.
