Features • Medium-voltage and Standard-voltage Operation – 2.7 (VCC = 2.7V to 5.5V) • Automotive Temperature Range –40°C to +125°C • User Selectable Internal Organization – 16K: 2048 x 8 or 1024 x 16 • 3-wire Serial Interface • Sequential Read Operation • Schmitt Trigger, Filtered Inputs for Noise Suppression • 2 MHz Clock Rate (5V) Compatibility • Self-timed Write Cycle (10 ms max) Three-wire • High Reliability – Endurance: 1 Million Write Cycles Serial – Data Retention: 100 Years • Lead-Free/Halogen-Free Devices Available Automotive • 8-lead JEDEC SOIC and 8-lead TSSOP Packages EEPROM Description The AT93C86A provides 16384 bits of serial electrically erasable programmable read 16K (2048 x 8 or 1024 x 16) only memory (EEPROM), organized as 1024 words of 16 bits each when the ORG pin is connected to VCC and 2048 words of 8 bits each when it is tied to ground. The device is optimized for use in many automotive applications where low-power and low- AT93C86A voltage operations are essential. The AT93C86A is available in space saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. Table 1.
