Electrical characteristics

STM32F302xx/STM32F303xx

SPI/I2S characteristics

Unless otherwise specified, the parameters given in Table 61 for SPI or in Table 62 for I2S

are derived from tests performed under ambient temperature, fPCLKx frequency and VDD

supply voltage conditions summarized in Table 22.

Refer to Section 6.3.14: I/O port characteristics for more details on the input/output alternate

function characteristics (NSS, SCK, MOSI, MISO for SPI and WS, CK, SD for I2S).

1. Data based on characterization results, not tested in production.

2. Min time is for the minimum time to drive the output and the max time is for the maximum time to validate

the data.

3. Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put

the data in Hi-Z.
