Product details

192 KB Flash, 20 KB RAM, 6 KB EEPROM — memory budget for a connected sensor node

The STM32L073VZI6TR: 192 KB Flash, 20 KB RAM, and 6 KB EEPROM on-chip. The 32 MHz ARM Cortex-M0+ core keeps active current low while still handling sensor polling, USB communication, and LCD segment drive without a co-processor.

100-UFBGA (7x7 mm) — tight footprint, hand-assembly considerations

100-UFBGA package, 7x7 mm.

Peripheral set: USB, LCD drive, 16-channel 12-bit ADC

Connectivity includes USB (device), I²C, SPI, UART/USART with LIN and IrDA support, plus an I²S audio interface. The 84 GPIOs are enough to drive a segment LCD directly (the peripheral set includes an LCD controller), and the 16-channel 12-bit ADC plus two 12-bit DACs cover analog sensor inputs. Brown-out detect and POR are integrated, so external reset supervision is optional.

Frequently asked questions

Does STM32L073VZI6TR have USB connectivity?

Yes, the connectivity list includes USB, along with I²C, SPI, UART/USART, LIN, and IrDA.

Is STM32L073VZI6TR compatible with the STM32L0 series?

Yes, it is part of the STM32L0 series and is pin-compatible with other STM32L073VxI6 devices in the same 100-UFBGA footprint. The base product number is STM32L073, so code and peripheral migration within the L0 family is straightforward.
