93C46
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 mercial applications where low-power and low-voltage operations are essential.
Key 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
