AT93C86A Datasheet | Atmel

3-wire Automotive Temperature Serial EEPROM 16K (2,048 x 8 or 1,024 x 16) 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: 2,048 x 8 or 1,024 x 16 - 3-wire Serial Interface - Sequential Read Operation - Schmitt Trigger, Filtered Inputs for Noise Suppression - 2MHz Clock Rate (5V) patibility - Self-timed Write Cycle (10ms max) - High Reliability ̶ Endurance: 1,000,000 Write Cycles ̶ Data Retention: 100 Years - Lead-Free/Halogen-Free Devices Available - 8-lead JEDEC SOIC and 8-lead TSSOP Packages Description The AT93C86A provides 16,384 bits of Serial Electrically Erasable Programmable Read-Only Memory (EEPROM), organized as 1,024 words of 16 bits each when the ORG pin is connected to VCC and 2,048 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-voltage operations are essential. The AT93C86A is available in space saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. The AT93C86A is enabled through the Chip Select pin (CS), and accessed via a 3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a READ instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The write cycle is pletely self-timed and no separate erase cycle is required before Write. The write cycle is only enabled when the part is in the Erase/Write Enable state. When CS is brought “high” following the initiation of a write cycle, the DO pin outputs the Ready/Busy status of the part. The AT93C86A is available in a 2.7V to 5.5V version.
