CAT25C01/02/04/08/16
Doc. No. 1016, Rev. N
FUNCTIONAL DESCRIPTION
The CAT25C01/02/04/08/16 supports the SPI bus data
transmission protocol. The synchronous Serial Periph-
eral Interface (SPI) helps the CAT25C01/02/04/08/16 to
interface directly with many of today’s popular
microcontrollers. The CAT25C01/02/04/08/16 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
the operation to be performed.

(2) This parameter is tested initially and after a design or process change that affects the parameter.
(3) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.

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
25C01/02/04/08/16. 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 25C01/02/04/08/16. 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
