Notes: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings"
may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other
conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and
other relevant quality documents.

3. EIAJ IC-121 (Condition C) (200pF, 0Ω)
DESCRIPTION (cont’d)
The device connected to the bus is selected when
the chip select input (S) goes low. Communications
with the chip can be interrupted with a hold input
(HOLD). The write operation is disabled by a write
protect input (W).
Data is clocked in during the low to high transition
of clock C, data is clocked out during the high to
low transition of clock C.
SIGNALS DESCRIPTION
Serial Output (Q). The output pin is used to trans-
fer data serially out of the Memory. Data is shifted
out on the falling edge of the serial clock.
Serial Input (D). The input pin is used to transfer
data serially into the device. It receives instructions,
addresses, and the data to be written. Input is
latched on the rising edge of the serial clock.
