Product details

Active production, no end-of-life signal

The STM32L072CZT7TR is an active part with no end-of-life signal.

32 MHz Cortex-M0+ with on-chip EEPROM — what it saves on the BOM

Its memory mix — 192 KB Flash, 20K x 8 RAM, and 6K x 8 EEPROM — is the standout feature for a sensor-node or IoT-edge design: the embedded EEPROM holds calibration constants and configuration parameters without an external serial EEPROM, saving board area and a supply line. USB connectivity (with on-chip PHY) is available for direct PC connection, and the 13-channel 12-bit ADC plus two 12-bit DACs cover analog front-end needs without an external converter.

Peripherals and I/O for a sensor-node design

Forty GPIOs in the 48-LQFP package give enough headroom for a typical sensor hub: I²C and SPI for sensors, UART/USART for a radio module or debug console, and USB for direct host connection.

Frequently asked questions

What is the difference between STM32L072CZT7 and STM32L072CZT7TR?

The difference is the shipping medium: STM32L072CZT7 is typically supplied in tray or tube packaging, while the STM32L072CZT7TR suffix indicates Tape & Reel (TR) packaging intended for automated pick-and-place assembly. The silicon, firmware, and electrical ratings are identical.

What are the alternatives to STM32L072CZT7TR?

Within the STM32L0 family, pin-compatible alternatives include the STM32L071xx series (reduced Flash/RAM, no EEPROM) and the STM32L073xx series (additional USB and LCD controller). All share the same 48-LQFP footprint and Cortex-M0+ core, so a BOM swap does not require a PCB respin. For a direct parametric match with the same 192 KB Flash and 6 KB EEPROM, the STM32L072xx base part number covers the same die in different package/shipping variants.
