Description
The AT93C86A is accessed via a simple and versatile three-wire serial communication
interface. Device operation is controlled by seven instructions issued by the host pro-
cessor. 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 mem-
ory location 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 sup-
ports 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 instruction is executed or V CC 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 sta-
tus of the part if CS is brought high after being kept low for a minimum of 250 ns (t CS ). 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 WP 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
