Product details

Core specs and memory budget

The 64-LQFP package gives you 51 I/Os, plus a 12-bit ADC with 16 channels and a single 12-bit DAC.

Power rail and temperature grade

No automotive qualification here (no AEC-Q100), so keep it out of the engine bay.

For communication you get I²C, IrDA, SPI, UART/USART, and USB — enough for a typical IoT edge node or a human-machine interface with a small display.

The TR suffix means it ships in Tape & Reel, ready for pick-and-place. We source it through independent distribution and quote firm pricing and lead time against an RFQ — no stock number on the page, but we can confirm availability at quote time.

Frequently asked questions

What is the difference between STM32L053R8T6 and STM32L053R8T6TR?

The two parts are electrically identical. The STM32L053R8T6 ships in a tray, while the STM32L053R8T6TR ships in Tape & Reel. Choose the TR variant if your assembly line uses automated pick-and-place; use the tray version for hand assembly or low-volume builds.

Is STM32L053R8T6TR pin compatible with STM32L052R8T6?

Yes, the STM32L053R8T6TR is pin compatible with the STM32L052R8T6 in the same 64-LQFP package. The L053 adds EEPROM and an LCD driver; the L052 lacks those but is otherwise a drop-in replacement for the same footprint.
