Product details

What this STM32L011F3P6 brings to the board

With 16 I/Os, I²C, SPI, UART, and a 9-channel 12-bit ADC, it fits into compact 20-TSSOP designs where every millimetre of board space counts.

8 KB of Flash is tight: a typical STM32L0 HAL plus a minimal RTOS kernel leaves about 4 KB to 5 KB for application code. The 2 KB SRAM handles a few local buffers and a modest call stack. The 512 bytes of EEPROM are useful for calibration constants, node IDs, or fault logs that survive a power cycle — no external EEPROM needed. If your firmware image or data buffers exceed this, you are looking at the next density step in the STM32L0 family, like the STM32L031 with 32 KB Flash.

Supply and temperature — where it works

The 1.65 V minimum supply means this MCU keeps running as a single-cell Li-ion battery discharges to its cutoff.

No last-time-buy or obsolescence risk for current designs.

Frequently asked questions

What is the closest pin-compatible alternative to the STM32L011F3P6?

Within the STM32L0 series, the STM32L011F3P6 shares the same 20-TSSOP footprint and pinout as other STM32L011 variants with different Flash densities (e.g., STM32L011D3P6 with 8 KB Flash). For higher memory, the STM32L031F6P6 (32 KB Flash) is pin-compatible across the same package, but verify the peripheral set differences in the datasheet.
