Product details

Core and memory headroom for display and control

The STM32L4R7VIT6: On-chip memory totals 2 MB of Flash and 640 KB of SRAM — the Flash holds a full graphics stack and application code, while the RAM budget supports a 320x240 frame buffer plus an RTOS task pool without external memory.

Peripheral set and connectivity

83 general-purpose I/Os are available across the 100-LQFP package (14x14 mm body), enough to drive a parallel LCD interface alongside sensor inputs and actuator outputs. Connectivity covers CANbus, USB OTG, multiple SPI/I²C/UART interfaces, plus an external memory controller (EBI/EMI) and an MMC/SD card host — this MCU can serve as the system hub for a mixed-signal board with local storage and fieldbus.

The part is ROHS3 compliant, covering EU RoHS directive exemptions through 2024.

Frequently asked questions

What is the core speed of STM32L4R7VIT6?

The ARM Cortex-M4 core runs at 120 MHz maximum, with single-cycle multiply and hardware FPU/DSP extensions for signal processing workloads.

What is the closest pin-compatible alternative in the STM32L4R family?

The STM32L4R series includes multiple memory and peripheral variants in the same 100-LQFP footprint. The base product number STM32L4R7 identifies this specific Flash/RAM configuration. A parametric search on the STM32L4R base number will show sibling parts with the same pinout but different memory sizes.

What compliance documentation does STMicroelectronics provide for STM32L4R7VIT6?

The part is ROHS3 compliant. STMicroelectronics provides a full compliance package including REACH and conflict minerals declarations through their standard documentation portal.
