Application guidelines
AN2846
18/35
Doc ID 15130 Rev 1
Figure 26 shows a 16-bit transmission example when the application is running in good
conditions:
●
Application is correctly supplied: /UVA, Bit 7 not activated
●
SCLT3-8 junction temperature less than 150 °C: /OTA, bit 6 not activated
●
Correct transmission: parity bits in accordance with input states

SPI timing definition
The four SPI signals involved: /CS, SCK, MOSI, MISO are described in Figure 27. A fifth
/MISO pin output signal is also present.
The typical SCK frequency is 1 MHz, but the SCLT3 can run at up to 2 MHz. The other more
important timing parameters are:
●
tD: Delay time. This is the delay time of MISO between SCK falling edge and MISO
change.
●
tS: Set up time. This is the minimum holding time of MOSI input data for its capture
before the SCK rising edge.
●
tH: Holding time. This is the minimum holding time of MOSI input data after the SCK
rising edge for its correct capture.
The most important rules to meet to perform a correct data transmission are:
●
tCL > tD + tS
●
tCH > tH.
