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 -40C to +125C 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.

Functional Description The AT93C86A is accessed via a simple and versatile 3-wire serial communication interface. The device operation is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising edge of CS and consists of a Start Bit (Logic 1) followed by the appropriate Opcode and the desired memory address location. READ: The READ instruction contains the address code for the memory location to be read. After the instruction and address are decoded, data from the selected memory location is available at the Serial Output (DO) pin. Output data changes are synchronized with the rising edges of Serial Clock (SK). The AT93C86A supports sequential Read operations. The device will automatically increment the internal address pointer and clock out the next memory location as long as CS is held high. In this case, the dummy bit (Logic 0) will not be clocked out between memory locations, thus allowing for a continuous stream of data to be read. Note: A dummy bit (Logic 0) precedes the 8- or 16-bit data output string. Figure 6-1. READ Timing tCS CS SK DI 1 1 0 AN A0 High-impedance DO 0 DN D0 ERASE/WRITE (EWEN): To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when power is first applied. An EWEN instruction must be executed first before any programming instructions can be carried out. Note: Once in the EWEN state, programming remains enabled until an EWDS instruction is executed or VCC power is removed from the part. Figure 6-2. EWEN Timing tCS CS SK DI 1 0 0 1 1 ... AT93C86A Automotive [DATASHEET] Atmel-5096G-SEEPROM-AT93C86A-Automotive-Datasheet_022016 7 ERASE: The ERASE instruction programs all bits in the specified memory location to the Logic 1 state. The self-timed erase cycle starts once the ERASE instruction and address are decoded. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250ns (tCS). A Logic 1 at DO pin indicates the selected memory location has been erased, and the part is ready for another instruction. Figure 6-3. ERASE Timing tCS CS Standby Check Status SK DI 1 1 1 AN AN-1 AN-2 ... A0 tDF tSV DO High-impedance High-impedance Busy Ready tWP WRITE: The WRITE instruction contains the 8 or 16 bits of data to be written into the specified memory location. The self-timed programming cycle tWP starts after the last bit of data is received at Serial Data Input (DI) pin. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250ns (tCS). A Logic 0 at DO indicates that the programming is still in progress. A Logic 1 indicates that the memory location at the specified address has been written with the data pattern contained in the instruction and the part is ready for further instructions. A Ready/Busy status cannot be obtained if the CS is brought high after the end of the self-timed programming cycle tWP. Figure 6-4. WRITE Timing tCS CS SK DI DO 1 0 1 AN ... A0 DN ...

The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250ns (tCS). The ERAL instruction is valid only at VCC = 5.0V 10%. Figure 6-5.

The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250ns (tCS). The WRAL instruction is valid only at VCC = 5.0V ±10%. Figure 6-6.

The operation of the READ instruction is independent of both the EWEN and EWDS instructions and can be executed at any time. Figure 6-7.

Power shall rise monotonically from 0.0Vdc to full VCC in less than 1ms. Hold at full VCC for at least 100μs before the first operation. Power shall drop from full VCC to 0.0Vdc in less than 1ms. Power dropping to a non-zero level and then slowly going to zero is not recommended. Power shall remain off (0.0Vdc) for 0.5s minimum. Please consult Atmel if your power conditions do not meet the above recommendations. AT93C86A Automotive [DATASHEET] Atmel-5096G-SEEPROM-AT93C86A-Automotive-Datasheet_022016 11 8.
