M95080

16Kbit and 8Kbit Serial SPI Bus EEPROM With High Speed Clock

STMicroelectronics 

M95160, M95080

SPI Modes

These devices can be driven by a microcontroller

with its SPI peripheral running in either of the two

following modes:

– CPOL=0, CPHA=0

– CPOL=1, CPHA=1

For these two modes, input data is latched in on

the rising edge of Serial Clock (C), and output data

Figure 5. SPI Modes Supported

CPOL CPHA

is available from the falling edge of Serial Clock

(C).

The difference between the two modes, as shown

in Figure 5., is the clock polarity when the bus

master is in Stand-by mode and not transferring

data:

– C remains at 0 for (CPOL=0, CPHA=0)

– C remains at 1 for (CPOL=1, CPHA=1)
