ACE24C16A
Technology
Two-wire Serial EEPROM
Description
The ACE24C16A provides low operation voltage of 16384 bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as 2048 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operations are essential.
Features
z Low Operation Voltage: Vcc=1.7V to 5.5V
z Internally Organized: 2048x8
z Two-wire Serial Interface
z Schmitt Trigger, Filtered Inputs for Noise Suppression
z Bi-directional Data Transfer Protocol
z 1MHz(2.5V~5.5V) and 400kHz(1.7V) Compatibility
z Write Protect Pin for Hardware Data Protection
z 16-byte Page Write Modes
z Partial Page Writes are Allowed
z Self-timed Write Cycle (5 ms max)
z High-reliability - Endurance: 1,000,000 Write Cycles
- Data Retention: 100 Years
