1 / 17 page ACE24C128B/256B/512B Two-wire Serial EEPROM VER 1.4 1 Description The ACE24C128B/256B/512B provides 131,072/262,144/524,288 bits of serial electrically erasable and programmable read-only memory (EEPROM), organized as 16,384/32,768/65,536 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The ACE24C128B/256B/512B is available in space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is accessed via a two-wire serial interface. In addition, the ACE24C128B/256B/512B is available in 1.7V (1.7V to 5.5V) version. Features Wide Voltage Operation - VCC = 1.7V to 5.5V Operating Ambient Temperature: -40℃ to +85℃ Internally Organized: - ACE24C128B, 16,384 * 8 (128K bits) - ACE24C256B, 32,768 * 8 (256K bits) - ACE24C512B, 65,536 * 8 (512K bits) Two-wire Serial Interface Schmitt Trigger, Filtered Inputs for Noise Suppression Bidirectional Data Transfer Protocol 1 MHz (5V), 400 KHz (1.7V, 2.5V, 2.7V) Compatibility Write Protect Pin for Hardware Data Protection 64-byte Page (128K, 256K), 128-byte (512K) Write Modes Partial Page Writes Allowed Self-timed Write Cycle (5 ms max) High-reliability - Endurance: 1 Million Write Cycles - Data Retention: 100 Years Absolute Maximum Ratings DC Supply Voltage -0.3 to 6.5V Input / Output Voltage GND-0.3V to VCC+0.3V Operating Ambient Temperature -40℃ to 85℃ Storage Temperature -65℃ to 150℃ *Notice: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification are not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. |
