Product details

80 MHz Cortex-M4 with 1 MB Flash — what the memory and speed mean for the design

It carries 1 MB of Flash and 128 KB of SRAM — enough headroom for a real-time control loop with a display buffer and OTA staging area without external memory.

Peripheral set — CAN, QSPI, SAI, and 51 I/O

The 51 general-purpose I/O lines are enough to interface a parallel LCD, a keypad matrix, and a handful of sensors without an I/O expander. The connectivity block includes CANbus for industrial networking, QSPI for a serial NOR Flash or PSRAM, SAI for audio codec or digital microphone input, and SWPMI for smart-card or NFC reader links.

Active lifecycle — no last-time-buy risk

Frequently asked questions

What is the core processor of the STM32L471RGT6TR?

The core is an ARM Cortex-M4, 32-bit single-core, with a floating-point unit and single-cycle multiply, clocked at 80 MHz.

What is the closest functional equivalent or replacement for the STM32L471RGT6TR?

Within the STM32 family, the STM32L151CBU6A is a lower-performance sibling — it uses a Cortex-M3 core at 32 MHz with less Flash and fewer I/O. It is not a pin-compatible drop-in; the STM32L471RGT6TR offers roughly 2.5× the core speed, more than double the Flash, and a richer peripheral set including QSPI and SAI. For a true functional replacement, stay within the STM32L4 series.
