AT93C86A-10PU-1.8

Three-wire Serial EEPROM 16K (2048 x 8 or 1024 x 16)

Atmel Corporation 

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.

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions for extended periods may affect

device reliability

Note:

When the ORG pin is connected to Vcc, the x 16 organization is selected. When it is connected to ground, the x 8 organization

is selected. If the ORG pin is left unconnected and the application does not load the input beyond the capability of the internal 1

Meg ohm pullup, then the x 16 organization is selected.
