Description

Description
The AT93C46/56/66 provides 1024/2048/4096 bits of serial electrically erasable programmable read-only memory (EEPROM), organized as 64/128/256 words of 16 bits each (when the ORG pin is connected to VCC), and 128/256/512 words of 8 bits each (when the ORG pin is tied to ground). The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. The AT93C46/56/66 is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-lead dBGA2 packages.
Features
• Low-voltage and Standard-voltage Operation
– 2.7 (VCC = 2.7V to 5.5V)
– 1.8 (VCC = 1.8V to 5.5V)
• User-selectable Internal Organization
– 1K: 128 x 8 or 64 x 16
– 2K: 256 x 8 or 128 x 16
– 4K: 512 x 8 or 256 x 16
• Three-wire Serial Interface
• 2 MHz Clock Rate (5V)
• Self-timed Write Cycle (10 ms max)
• High Reliability
– Endurance: 1 Million Write Cycles
– Data Retention: 100 Years
• Automotive Grade, Extended Temperature and Lead-Free/Halogen-Free Devices Available
• 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-ball dBGA2 Packages
