2. Description

The AT93C86A provides 16384 bits of serial electrically erasable programmable read

only memory (EEPROM), organized as 1024 words of 16 bits each when the ORG pin

is connected to V

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-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

three-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.

3. Functional Description

The AT93C86A is accessed via a simple and versatile 3-wire serial communication interface.

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 Op Code and the desired memory address location.

READ (READ):

The Read (READ) instruction contains the address code for the memory loca-

tion to be read. After the instruction and address are decoded, data from the selected memory

location is available at the serial output pin DO. Output data changes are synchronized with the

rising edges of serial clock SK. It should be noted that a dummy bit (logic “0”) precedes the 8- or

16-bit data output string. 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.

ERASE/WRITE (EWEN):

To assure data integrity, the part automatically goes into the

Erase/Write Disable (EWDS) state when power is first applied. An Erase/Write Enable (EWEN)

instruction must be executed first before any programming instructions can be carried out.

Please note that once in the EWEN state, programming remains enabled until an EWDS instruc-

tion is executed or V

power is removed from the part.

ERASE (ERASE):

The Erase (ERASE) instruction programs all bits in the specified memory

location to the logical “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 250 ns (t

). A logic “1” at pin DO indicates that the

selected memory location has been erased, and the part is ready for another instruction.

WRITE (WRITE):

The Write (WRITE) instruction contains the 8 or 16 bits of data to be written

into the specified memory location. The self-timed programming cycle t

starts after the last bit

of data is received at serial data input pin DI. The DO pin outputs the Ready/Busy status of the

part if CS is brought high after being kept low for a minimum of 250 ns (t

). A logic “0” at DO

indicates that 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 t

ERASE ALL (ERAL):

The Erase All (ERAL) instruction programs every bit in the memory array

to the logic “1” state and is primarily used for testing purposes. The DO pin outputs the

Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns

). The Eral instruction is valid only at V

= 5.0V

10%.

WRITE ALL (WRAL):

The Write All (WRAL) instruction programs all memory locations with the

data patterns specified in the instruction. The DO pin outputs the Ready/Busy status of the part if

CS is brought high after being kept low for a minimum of 250 ns (t

). The Wral instruction is

valid only at V

= 5.0V ± 10%.

ERASE/WRITE DISABLE (EWDS):

To protect against accidental data disturbance, the

Erase/Write Disable (EWDS) instruction disables all programming modes and should be exe-

cuted after all programming operations. The operation of the Read instruction is independent of

both the Ewen and Ewds instructions and can be executed at any time.
