1. I = input, O = output, S = supply.

2. FT = 5 V tolerant.

3. Function availability depends on the chosen device. For devices having reduced peripheral counts, it is always the lower

number of peripheral that is included. For example, if a device has only one SPI and two USARTs, they will be called SPI1

and USART1 & USART2, respectively. Refer to Table 2 on page 10.

4. Applicable to STM32L152xx devices only. In STM32L151xx devices, this pin should be connected to VDD.

5. The PC14 and PC15 I/Os are only configured as OSC32_IN/OSC32_OUT when the LSE oscillator is on (by setting the

LSEON bit in the RCC_CSR register). The LSE oscillator pins OSC32_IN/OSC32_OUT can be used as general-purpose

PC14/PC15 I/Os, respectively, when the LSE oscillator is off ( after reset, the LSE oscillator is off ). The LSE has priority

over the GPIO function. For more details, refer to Using the OSC32_IN/OSC32_OUT pins as GPIO PC14/PC15 port pins

section in the STM32L15xxx reference manual (RM0038).

6. The PH0 and PH1 I/Os are only configured as OSC_IN/OSC_OUT when the HSE oscillator is on ( by setting the HSEON

bit in the RCC_CR register). The HSE oscillator pins OSC_IN/OSC_OUT can be used as general-purpose PH0/PH1 I/Os,

respectively, when the HSE oscillator is off (after reset, the HSE oscillator is off ). The HSE has priority over the GPIO

function.

7. Unlike in the LQFP64 package, there is no PC3 in the TFBGA64 package. The VREF+ functionality is provided instead.
