STMicroelectronics · Microcontrollers (MCU/MPU/SOC) · TSSOP-14

STM32L011D4P6 from STMicroelectronics, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model, then checked against ST open pin data); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PB9-BOOT0 bidirectional Boot memory selection pin; determines whether device boots from Flash memory, System memory, or embedded RAM on reset.
2 PC14-OSC32_IN bidirectional Low-speed external oscillator input pin for 32.768 kHz crystal oscillator connection with 5V tolerance.
3 PC15-OSC32_OUT bidirectional Low-speed external oscillator output pin for 32.768 kHz crystal oscillator connection with standard 3.3V tolerance.
4 NRST bidirectional Active-low reset input with embedded weak pull-up resistor (30 to 60 kΩ) and internal RC filter for device reset control.
5 PA0-CK_IN bidirectional VDD-tolerant analog-capable GPIO supporting ADC channel 0, external clock input, timer input capture, and USART receive functions.
6 PA1 bidirectional 5V-tolerant GPIO pin supporting timer channel compare, I2C slope master bit address, and USART control signal functions.
7 PA4 bidirectional VDD-tolerant analog-capable GPIO supporting ADC channel 4, SPI chip select, I2C clock, and comparator alternate functions.
8 PA7 bidirectional 5V-tolerant GPIO pin supporting SPI MOSI output, timer output compare, low-power timer output, and comparator output functions.
9 VSS power_in Digital and analog ground (0V) reference providing current return path for all internal circuits and external connections.
10 VDD power_in Main digital power supply input ranging from 1.8V to 3.6V for all I/O and internal logic; VDDA is internally connected on TSSOP14 package.
11 PA9 bidirectional 5V-tolerant FM+ capable I2C pin with 20 mA drive current supporting I2C fast mode plus up to 1 Mbit/s, USART transmit, and MCO output.
12 PA10 bidirectional 5V-tolerant FM+ capable I2C pin with 20 mA drive current supporting I2C fast mode plus up to 1 Mbit/s, USART receive, and RTC reference input.
13 PA13 bidirectional 5V-tolerant Serial Wire Debug I/O pin supporting I2C data, SPI clock, LPUART receive, low-power timer functions, and GPIO operations.
14 PA14 bidirectional 5V-tolerant Serial Wire Debug Clock pin supporting USART transmit, SPI MISO, LPUART transmit, low-power timer output, and GPIO operations.
