Product details

Active production, 120 MHz Cortex-M4 with 2 MB Flash

The 169-ball UFBGA package (7x7 mm) houses the STM32L4R5AII6.

On-chip brown-out detect and POR eliminate external supervisor ICs in many designs.

Peripheral set and connectivity

Connectivity includes CANbus, USB OTG, multiple I²C and SPI interfaces, plus an external memory interface (EBI/EMI) for expanding RAM or Flash off-chip. The 112 I/O lines give plenty of headroom for parallel displays, keypads, or sensor arrays. On-chip data converters include a 16-channel 12-bit ADC and two 12-bit DACs.

Lifecycle status — active, no end-of-life risk

ST lists the STM32L4R5AII6 as Active.

Frequently asked questions

What is the maximum clock speed of STM32L4R5AII6?

The STM32L4R5AII6 runs at 120 MHz from the ARM Cortex-M4 core. At that speed, the Flash needs at least one wait state inserted — the STM32L4R series handles this automatically via the prefetch buffer and ART accelerator, so the designer doesn't need to manage wait states manually in most cases.
