CAT25C08/16
Doc. No. 1016, Rev. C
2006 by Catalyst Semiconductor, Inc.
Characteristics subject to change without notice
FUNCTIONAL DESCRIPTION
The CAT25C08/16 supports the SPI bus data transmis-
sion protocol. The synchronous Serial Peripheral Inter-
face (SPI) helps the CAT25C08/16 to interface directly
with many of today
’
s popular microcontrollers. The
CAT25C08/16 contains an 8-bit instruction register.
(The instruction set and the operation codes are de-
tailed 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
the operation to be performed.

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
25C08/16. 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 25C08/16. During a read cycle,
data is shifted out on the falling edge of the serial clock
for SPI modes (0,0 & 1,1).
SCK:
Serial Clock
SCK is the serial clock pin. This pin is used to synchro-
nize the communication between the microcontroller
