Key Features
- Ultra-low-power Cortex-M4 with FPU at 80 MHz delivering 100 DMIPS with Stop 2 mode under 1 µA for battery-powered IoT designs
- 1 MB Flash and 128 KB SRAM with DMA channels support complex firmware and real-time data buffering in industrial sensor applications
- Integrated 12-bit ADC, DAC, op-amp, and comparator with LQFP-64 package enables full analog signal chain without external components
Applications
STM32L471RGT6TR suits industrial IoT gateways, energy metering, and portable medical devices requiring large program memory and ultra-low power consumption. Its 1 MB Flash supports over-the-air firmware update stacks alongside application code, while Stop 2 mode under 1 µA extends battery life in smart meter and asset tracker designs. The 80 MHz Cortex-M4 with FPU handles real-time DSP tasks such as FFT-based vibration analysis and filter coefficient computation between low-power sleep intervals.

Frequently Asked Questions
How does the 1 MB Flash in the STM32L471RGT6TR enable OTA update capability in IoT deployments?
The STM32L471RGT6TR's 1 MB Flash allows partitioning into two 512 KB banks for dual-bank OTA firmware updates, enabling one bank to receive a new image while the other runs the active firmware. This architecture supports fail-safe rollback at 80 MHz without external NOR Flash, saving approximately $0.50 per unit in BOM cost versus designs requiring external memory chips.
For an energy meter design, what advantages do the integrated ADC and DAC of the STM32L471RGT6TR offer?
The STM32L471RGT6TR integrates a 12-bit ADC with up to 16 channels and a 12-bit DAC, enabling direct current and voltage sampling in single-phase energy meters without external signal chain ICs. Sampling at up to 1 Msps at 3.3 V supply, the integrated ADC meets Class 1 energy measurement accuracy for residential smart meters while reducing BOM cost by eliminating a dedicated metering AFE.
When should a designer choose the STM32L471RGT6TR tape-and-reel variant over the non-TR version for high-volume production?
Choose the STM32L471RGT6TR (TR suffix tape-and-reel) when production volumes exceed 1000 units per run, as the 3000-piece tape-and-reel packaging is compatible with pick-and-place automated SMT lines running at 64-pin LQFP footprint. The non-TR tray format suits prototyping and low-volume runs under 500 units, while the TR format reduces per-reel handling time by approximately 60% in high-volume factory environments.
