The 120 MHz Cortex-M4 core handles DSP and control loops. The 1 MB Flash and 640 KB SRAM support application stacks and data logging. Connectivity includes CANbus, USB OTG, multiple SPI/I²C/UART interfaces, and an external memory interface (EBI/EMI) — covering most industrial and consumer bus requirements.

Product details
Frequently asked questions
What is the exact package of STM32L4R9ZGY6TR?
The STM32L4R9ZGY6TR comes in a 144-WLCSP (wafer-level chip-scale package) measuring 5.24x5.24 mm, with 0.5 mm ball pitch.
How many analog inputs does STM32L4R9ZGY6TR have?
The MCU integrates 16 channels of 12-bit ADC and two 12-bit DAC channels.
Can STM32L4R9ZGY6TR be used as a drop-in replacement for STM32L4R9ZGY6?
The STM32L4R9ZGY6 (non-TR suffix) is the tray-packaged variant of the same die and package. The TR suffix indicates tape-and-reel packaging only — the silicon, package, and electrical ratings are identical. For pick-and-place reels, order the TR suffix; for hand-assembly or small quantities, the tray variant is functionally interchangeable.
