Electrical characteristics
STM32L151x6/8/B, STM32L152x6/8/B
SPI characteristics
Unless otherwise specified, the parameters given in the following table are derived from
tests performed under ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized in Table 14.
Refer to Section 6.3.11: I/O current injection characteristics for more details on the
input/output alternate function characteristics (NSS, SCK, MOSI, MISO).

1. The characteristics above are given for voltage range 1.
2. Based on characterization, not tested in production.
3. The maximum SPI clock frequency in slave transmitter mode is given for an SPI slave input clock duty
cycle (DuCy(SCK)) ranging between 40 to 60%.
4. Min time is for the minimum time to drive the output and max time is for the maximum time to validate the
data.
