Product details

192 KB Flash, 20 KB SRAM — sizing the firmware budget

For a LoRa end-node waking every hour to send a sensor reading, the wide supply tolerance simplifies the power tree and saves a regulator's quiescent current.

For a BOM that needs multi-year supply assurance, this is a clean fit — no LTB math or broker dependency required.

100-LQFP (14x14) — board footprint and routing

Keep the decoupling caps close to each VDD/VSS pair — the datasheet's typical layout is a good starting point for first-power bring-up.

Frequently asked questions

What is the flash memory size of STM32L071VZT6?

The STM32L071VZT6 has 192 KB of Flash program memory (192K x 8).

What are the best alternatives to STM32L071VZT6?

A functional alternative within the STM32 portfolio is the STM32L151CBU6A, which uses an ARM Cortex-M3 core at the same 32 MHz clock speed and includes a 12-bit DAC, but comes in a smaller 48-pin package with fewer I/O (37) and no on-chip EEPROM.
