CAT25C11/03/05/09/17
Doc. No. 1017, Rev. J
FUNCTIONAL DESCRIPTION
The CAT25C11/03/05/09/17 supports the SPI bus data
transmission protocol. The synchronous Serial Periph-
eral Interface (SPI) helps the CAT25C11/03/05/09/17 to
interface directly with many of today
’
s popular
microcontrollers. The CAT25C11/03/05/09/17 contains
an 8-bit instruction register. (The instruction set and the
operation codes are detailed in the instruction set table)
After the device is selected with
CS
going low, the first
byte will be received. The part is accessed via the SI pin,
with data being clocked in on the rising edge of SCK.
The first byte contains one of the six op-codes that define

PIN DESCRIPTION
SI:
Serial Input
SI is the serial data input pin. This pin is used to input all
opcodes, byte addresses, and data to be written to the
25C11/03/05/09/17.Input data is latched on the rising
edge of the serial clock for SPI modes (0, 0 & 1, 1).
SO:
Serial Output
SO is the serial data output pin. This pin is used to transfer
data out of the 25C11/03/05/09/17. During a read cycle,
data is shifted out on the falling edge of the serial clock for
