AT93C46中文资料Three-wire Serial EEPROMs数据手册Microchip规格书

描述 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.
