32 MHz Cortex-M0+ with 192 KB Flash and on-chip EEPROM
The STM32L072CZT6TR: It also integrates 6 KB of true EEPROM, which eliminates the need for an external serial EEPROM for parameter storage in sensor nodes or data loggers.
Analog and connectivity for sensor-hub designs
A 10-channel 12-bit ADC and dual 12-bit DAC are on-chip, so a three-axis accelerometer plus a temperature sensor can be read without external ADC. The USB interface supports HID or CDC class for direct PC connection in data-logging applications. With 37 GPIOs in the 48-LQFP package, there is enough headroom for a parallel LCD interface alongside I²C and SPI peripherals. The internal oscillator saves two external capacitors and a crystal, reducing BOM count for cost-sensitive designs.
Industrial temperature range and active lifecycle
The brown-out detect and POR circuits ensure clean reset on supply dips. STMicroelectronics lists the STM32L072CZT6TR as Active. The base part number STM32L072 covers multiple memory and package variants for BOM flexibility.
