Overview
AT93C86A 3-wire Automotive Temperature Serial EEPROM 16K (2,048 x 8 or 1,024 x 16) DATASHEET 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) Compatibility  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 completely 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.
