Product details

What this STM32L072KZT6 brings to a battery-powered design

It packs 192 KB of Flash program memory, 20 KB of SRAM, and 6 KB of embedded EEPROM — enough to run a lightweight RTOS with sensor fusion and data logging without external storage. Typical applications include battery-powered IoT edge nodes, portable medical monitors, smart sensors, and wireless environmental loggers where every microamp matters.

Memory and peripheral budget — sizing the BOM

With 192 KB of Flash and 20 KB of RAM, this part fits firmware images for BLE stacks, sensor drivers, and a modest application layer. The 6 KB EEPROM is useful for calibration constants, device IDs, and configuration parameters that survive a firmware update. The 25 general-purpose I/Os in the 32-LQFP package are enough for a sensor array with SPI or I²C bus, a few pushbuttons, and status LEDs.

Supply voltage and temperature — where it works

No extended-temperature or automotive qualification here, so it stays in the commercial/industrial tier.

Frequently asked questions

What is the difference between STM32L072KZT6 and STM32L073KZT6?

The STM32L073KZT6 is a close sibling in the same STM32L0 series, typically offering additional USB crystal-less operation and a few more peripheral options. The core, memory, and package are identical; the difference is in the USB PHY integration. Check the STM32L0 reference manual for the exact peripheral set delta.

Can STM32L072KZT6 be used in battery-powered IoT devices?

Yes, the 1.65 V minimum supply voltage, 32 MHz Cortex-M0+ core with multiple low-power modes, and integrated ADC/DAC make it well suited for battery-powered IoT edge nodes, wireless sensor tags, and portable instruments. The 192 KB Flash and 20 KB RAM are sufficient for BLE stacks and sensor fusion firmware.

What is the closest functional second-source for STM32L072KZT6?

The STM32L151CBU6A is a functional alternative from the STM32L1 series, featuring a Cortex-M3 core at 32 MHz, 37 I/Os, and a 16-channel 12-bit ADC. It offers more processing headroom and analog channels but draws higher active current. It is not pin-compatible — the STM32L151CBU6A comes in a 48-pin package — so a board redesign is required.
