ACE24C32/64
Technology
Two-wire Serial EEPROM
Description
The ACE24C32/64 provides 32,768/65,536 bits of serial electrically erasable and programmable read-only
memory (EEPROM) organized as 4096/8192 words of 8 bits each. The device’s cascadable feature allows up to
8 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 operations are essential.
Features
z Low Operation Voltage: Vcc = 1.7V to 5.5V
z Internally Organized: 4096 x 8,8192 x 8
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 400 kHz (1.7V) Compatibility
z Write Protect Pin for Hardware Data Protection
z 32-byte Page Write Modes (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
z TDFN ROHS compliant Packages
z Wafer Sales: available in inked wafer Form
