Product details

It packs 192 KB of Flash program memory, 20 KB of SRAM, and 6 KB of embedded EEPROM — enough for a moderate firmware image plus non-volatile parameter storage without an external serial EEPROM.

Memory and peripheral fit for a production BOM

With 192 KB Flash and 20 KB RAM, this part sits in the mid-range of the STM32L0 family — enough headroom for a FreeRTOS-based application with USB CDC or a Modbus stack, but not the 512 KB / 80 KB tier you'd pick for a GUI-heavy design. The 6 KB EEPROM is a genuine hardware block, not emulated Flash, so you get 100 kcycle endurance per byte without wear-leveling code.

Package and mounting

The 100-LQFP (14x14 mm) is a hand-solderable QFP with 0.5 mm pitch — no BGA rework station needed, but a decent hot-air station and a fine-tip iron are the right tools.

Frequently asked questions

Where can I buy STM32L073VZT6D and what is the price?

The STM32L073VZT6D is available to order through independent distribution.

What is the replacement for STM32L073VZT6D if it becomes unavailable?

There is no direct pin-compatible second source from another manufacturer. Within the STM32L073 family, the 100-LQFP footprint is shared across density options — the VZT6 (192 KB Flash) and V8T6 (64 KB Flash) are pin-compatible, so a BOM swap is possible with a firmware change.
