Product details

The STM32L471VET6: It targets industrial sensor nodes, building automation controllers, and battery-powered instrumentation where the balance of processing throughput and energy efficiency matters.

82 I/O and peripheral set — sizing the interface budget

With 82 I/O lines in a 100-LQFP package, this part gives you enough GPIO for parallel LCD interfaces, keypad matrices, or multiple encoder inputs without needing an I/O expander. The connectivity block includes CANbus, two I²C, SPI, QSPI, SAI (for audio), and SWPMI (single-wire protocol for smartcard or NFC). The QSPI interface is particularly useful for memory-mapped external Flash or PSRAM, stretching the effective storage without loading the core bus.

Industrial temperature range and data converters

The on-chip data converters — 16-channel 12-bit ADC and two 12-bit DACs — cover analog sensor acquisition and analog output generation without external converters, reducing BOM count and board area.

Frequently asked questions

What is the difference between STM32L471 and STM32L476?

The STM32L476 typically adds a larger SRAM option (128 KB vs 128 KB is the same here) and a Chrom-ART graphics accelerator, while the STM32L471 omits the graphics accelerator for a lower-cost entry point. Both share the same Cortex-M4 core, 80 MHz clock, and 100-LQFP footprint, so a board designed for one can often accept the other with a firmware change.

Can STM32L471VET6 be used as a replacement for STM32L476?

Yes, in many cases the STM32L471VET6 is pin-compatible with the STM32L476 in the same 100-LQFP package. The key difference is the absence of the Chrom-ART graphics accelerator on the L471. If your application does not use the hardware graphics engine, the L471 can serve as a drop-in replacement with a firmware update.
